View Full Version : New suspension 70 build
1979ATC110
04-30-2010, 05:58 PM
My 70 frame snapped in half a while back so I've now rounded up most of the parts to build my suspension frame. I'll post more pictures here as the build progresses.
I'm using a pit bike frame, making my own swingarm and triples.

Today I've been sizing everything up on the bench, trying to work out what wheelbase length I want to go for. I don't know how the extra length, width and rake affects the ride so it's really hard to decide. Maybe some of you guys can help me out here; The A+ frame looks about right to me - it obviously has a longer wheelbase than stock, can anyone tell me exactly what it is (or the length of the A+ swinger) and did the A+ use wheel spacers to increase the width to keep the overall geometry the same?

Nice start to a good build! Keep up the good work, and keep the pictures coming! I really like seeing the 70's with suspension, and even more of them being jumped! It must be a riot.

well iam just thinking outside the box but a little longer is prob better just like a extended swingarm.i dont have one but iam diff going to watch this build cause i have everything in the making to do this so .in due time i will be doing this .and i mean longer then the stock length on the stock 70 .

ONE THING TO LOOK AT, the neck is alot shorter and the top clamp will hit the tank right in the middle.. so adjustsments will have to be made there,,,
1979ATC110
05-04-2010, 06:15 AM
Thanks Kasey, I hadn't thought of that. Just looked at a few pictures of 70's on pit bike frames, they seem to have moved the tank back far enough to avoid them hitting, without it looking odd. I'll watch out for it.

I got the swingarm spot welded together, didn't want to weld it all in case I need to make changes. Also lowered the rear shock mount on the frame because it was in the way of the seat.

I like it :beer:
There are 1000 ways of building a suspended 70..........
What do those forks cost? and where can I grab a set, I was gonna chop down some 200X forks but those look pretty trick!
I think you may be angling that shock back a hair. Like you said, thats why it's just tack welded. The same reason I do it that way too.............
Nice work so far!! :D
1979ATC110
05-08-2010, 07:26 AM
Thanks Dirtcrasher, it's nice to get some feedback......
The forks are Marzocchi non-adjustables - Goggle it. They're Italian high quality forks, a proper adjustable set costs about $700!!!!!!!
These are only sold as part of of pit bike but occasionally they turn up on ebay form new bikes that have been dismantled for about a $100.
The rear shock is only 11 inches long, and the seat height as it is now, is 26 inches. I'll see how it rides, but you may be right.

In my haste to get the triples done I made a stupid mistake on the setting out, luckily I spotted it before I messed up the 2nd one. Managed to make a couple of 1 inch wheel spacers out of the centre part of the 1st but it meant I had to drive all the way out to the metal supplier today to get a replacement. Hopefully I'll get her rolling later this week.

Aluminium is strange stuff to work if you're used to steel, it's taken me a while to get the hang of it. Making something else first, like wheel spacers is a good idea, as it's not such a loss if you mess up and it gives you a chance to get used to working thick aluminium.

This is way cool to watch come together.
Pit bikes come with Marzocchi forks? Shock, too? Wow - I had no idea.
inv3ctiv3
05-11-2010, 03:52 PM
Everything looks great so far! But maybe angle down the shock a bit like DC said, the swing arm has a pretty crazy angle on it.
1979ATC110
05-12-2010, 06:16 PM
Yeah Marzocchi make forks for a few different types of bikes.
I haven't lowered the shock mount of the swingarm anymore as the angle affects the amount of leverage on the shock, and the shock is already quite hard and the angle is already less than it is on a pit bike. I'll see what it's like when she's rolling again.
Got all the holes drilled out on the yokes today, if all goes well I'll hopefully get them shaped up tomorrow and then I can finally start getting her up and rolling.

I had to go to an engineers shop yesterday to get a wider front axle turned, so while I was there I asked them to rough out the 2nd Ali triple for me - wont be ready till next Friday, so today I decided to have a go at knocking up a set of steel ones - a few hours later and they were almost done, just need welding in the morning.

^ YOU GUYS - Tell ME, JASON,SWIGIN and MANY OTHERS and we'll fabricate whatever you want.
BUT, there is almost never enough demand in this economy for anyone to tool up most of the time. I can't have 5000$ worth of Machine Shop equipment and make 10$ an hour......
Anyhow, I'm sure you found steel to be a bit easier. Aluminum is not very forgiving and like you said, not easy to weld!
Looking forward to seeing the finished product.

Of course daddy is going to be keeping it lubed and warm for her till she is ready. Wow? and hey?, why don't you guys spend time building more seriouse Trikes??? Not to take away from the awe of a suspended 70 though its coooooool.

Just curious I wanna do a suspendy 70 after a project or two more and I'm wondering what is everyone else do for triples? Does everyone make there own or does some bike out there fit perfect? Sorry to steal on a thread. I am watching this build and it is coming out beautifully. I just don't want to make my own triples if I don't have to... Thanks..
1979ATC110
05-22-2010, 06:07 AM
Triples are the most difficult part of the whole project. If you are going for inverted forks then you have no option but to make them or get them made. If your going to use normal forks then there are a quite a few different bikes you can probably use the triples from, most would require some adaptation though.
1979ATC110
05-22-2010, 04:23 PM
Hoped to get her running today but hit a few snags. The atc70 foot rest clashed with the pit bike frame which has a built in mounting for the 2 rear foot rest bolt holes, so I had to work something out without weakening anything - eventually by cutting a couple of slots and lots of wiggling I got them to go together.
http://www.vftshop.com/images/others/SNC00207.jpg
http://www.vftshop.com/images/others/SNC00206.jpg
Neither the atc70 or atc110 manifolds I have fit with the new frame - can anyone suggest one that might fit this or a work around?
http://www.vftshop.com/images/others/SNC00208.jpg
Also I was hoping my spare 110 chain would fit with the extra length but its 3 or 4 links short, so I might have to borrow a few link from my 110 for a while...

Have you thought about chain tension with that much slope on the swing arm?
1979ATC110
05-23-2010, 05:13 PM
I was desperate to have a ride on it today, so I modified the old 110 manifold and managed to get it to fit with a slight rise in the rear end of the tank. Threw on the exhaust, wiring, and chain - she fired up first time, I set off and... bang! the chain snapped... :-/
The way the rear suspension is at the moment, means when swing arm goes up the chain gets gradually tighter. I guess that's what you meant xr132 - another reason to move the shock mount farther down the arm?

Today I moved the bottom shock mount a couple of inches down the swing arm and raised the subframe up a bit to compensate. It's now got that V shape back that pit bike frames always have, and when I put the seat back on, its too high, I see why everyone else's ends up like a bar stool now... Think I might have to lower the swingarm pivot mount instead.... :wondering:
Drove all the way out to the nearest motorbike shop to buy a new longer chain today, only to find when I got back that it's the wrong size, so I still haven't got to ride this thing :cry:

hello
i dont claim to be a expert but dont the location of the swing arm bolt need to be higher up like inline with the motor sprocket? when i modded my 185s with a 200x rear i put it to low and it threw the chain and gave it a hell of a tight spot. i moved it to where it was almost even with the rear sprocket and that solved my prob.
did u place it where it is because you were setting up stance and trying to get more ground clearance?
love the build!!!!!
1979ATC110
05-25-2010, 05:56 AM
I'm no expert either, and if there is any out there, then they're keeping quite about it. I initially set it up so it had a good amount of suspension travel with the right seat height, good ground clearance and not too long a wheelbase. I didn't notice the chain would hit on the swingarm until I put one on.
The rear shock I have is designed for a pit bike and should be almost vertical - parallel to the upright part of the frame, that way it has a huge amount of leverage on it, as I move it farther down the swing arm there is less and less leverage, making the suspension harder and harder.
I'm thinking to put the shock mount and seat back as it was and instead move the swing arm pivot down so it's in line with the chain. Can anyone tell me of any other potential problems that might cause?

05-25-2010, 06:45 AM
a spring loaded chain tensioner would solve this.
AutoXer
05-25-2010, 08:41 AM
seems like it would allow you to run your chain looser at rest (+ you on it ) and have enough length when at full travel and a better slider and roller for your chain to run on would also be some thing to look into
1979ATC110
05-25-2010, 04:27 PM
Didn't get anything done on it today. I'll get back to the bike shop tomorrow and get a 420 chain and see what it looks like then, but it definitely needs a good tensioner and new slider. I have a roller, just need to fab up a bracket and spring. Not going to make any more alterations until I ridden it and got the feel of it.

05-26-2010, 04:15 PM
Got the right chain this morning, threw together a rough chain tensioner and finally got to ride it :) Hasn't lost any of the fun, the suspension's just made it much better. Couldn't really go for it though as the brake is hardly working - looks like the cable isn't long enough now that the wheelbase is longer.
Need to spend some time now working out all the little niggles and decide what changes need to be made before tearing it down for finishing and paint, then the final build up. Will post some pictures when it's all done.

On mine we cut the intake manifold and rewelded it at an angle that allowed it to fit fine. It was about a 75 degree angle. The carb jutted off to the side like a Harley. It was out of the way and looked cool as well.
1979ATC110
05-28-2010, 04:02 PM
Yeah, I think that's what I'm going to have to do. I've ordered a CT90 manifold, (which is the closest looking match to what I need) and a few low temperature aluminium welding rods so I can cut and modify it if necessary.

1979ATC110
05-29-2010, 06:01 AM
Someone else suggested a carb spinner so I made one up myself but it unfortunately didn't help - it makes the manifold even higher. The angle of most manifolds mean it hits the frame or tank at every turn. Need one with a very sharp angle that's about medium length, the CT90 looked about the best candidate. Post is really slow to here so it'll be a week before I'll have the parts to try it.
1979ATC110
05-29-2010, 05:50 PM
Ran into another problem today while making up a chain tensioner - the chain was so loose that the tensioner pushed it up against the bottom of the swingarm, so I took out 2 more links (the minimum possible) and then the chain was really tight and caused the rear sprocket to wobble and pulled apart the split link. The only way out of this I can see is to slightly shorten the swing arm... Anyone else come up against this?

WHAT ABOUT SPROCKET CHANGES TO GET THE DIAMETERS CLOSER? ATC70 has a 35 or 36 rear sprocket,, if your using 35 ADD a link and go with a 36 or vis versa since i don't have chain adjusters on 70 swingarms i use sprocket diameters ,,
Dirtcrasher
05-29-2010, 08:11 PM
^ I have had the same issue.... The halflinks I bought looked good but both broke.
You have to shorten it, make the chain length adjustable and or redesign your auto-tensioner.

I didn't know there are 2 different rear sprocket sizes, I thought about changing the front but it's already very tight to the engine casing and I didn't want to mess up the gear ratios.
What's the point of the rubber rear sprocket drive connector thingy, it's all a bit worn, can it easily be converted to a direct drive?
MuckUte
05-30-2010, 07:42 AM
There are a few sprocket sizes for the 70s. The rubbers in the rear drive are supposed to cussion the drivetrain from shock loading. The rubber inserts can still be purchased if they are worn or you could convert a brake drum similar to how the disk brake conversion is done as the splines are the same on both sides of the axle. The only other option to get rid of the rubber inserts would be to use an axle out of another bigger trike, this would also help with stability by widening the rear. I'm still thinkin about makin a r55 style swinger as i think that tube style looks sweet and the ball joints allow for adjustment of the swingarm length to sort out chain length problems.
1979ATC110
05-30-2010, 09:01 AM
I pulled off the rear sprocket this morning and it's a 35T, the rubber bits are totally mashed now after riding it with a very tight chain yesterday. Looking at it I reckon it would be quite easy to bolt the sprocket straight to the aluminium drive that holds the rubber bits - easier for me than trying to find another brake drum. Anyone done that before?
I like the r55 swingarm but if I build another it'll be like most quad swingarms that go inside the rear of the frame, not on the outsides so theres no way it can interfere with the chain.
1979ATC110
06-02-2010, 04:44 PM
The last couple of days I've been working out all the little faults and finishing off;
Shortened the swing arm by quarter inch and now it's the perfect length for the chain.
Bolted the rear sprocket directly to the drive hub, makes it a lot more responsive - wheelies galore.

Made up a sliding seat mount so I can use the kick start, works really well

Wow amazing job mate!
I only just found this build and its awsome!
Had I found it earlier I would have told you that your swing arm pivot has to be inline between the rear axle and the front sprocket shaft so that way the chain only gets looser from travel either way. It seems thats how its ended up anyway.
As for the intake manifold, did you try any of the china minibike manifolds?
The USD forks are awsome too by the way.
Thought of upping the horsepower yet?
Here is one done in Australia by the expert mad scientist mart.

As soon as I tried to put a chain on it I realised they should all be in line, I've got the swing arm set up now so that when I'm sat on it everything lines up perfect. It's really worth thinking about the chain length when your making up a swing arm - a 420 chain has 1/2" links so I needed a length that ends in a 1/4" or 3/4", it's now 12-3/4" centre to centre.
The engine in it is a beefed up CT110, it's already dangerously fast and so much fun that she leads you on into doing things you know you shouldn't, dont think I'd trust myself with a 140 in it...
I still haven't sorted the manifold properly, I got the CT90 one I'd ordered yesterday but is different to the picture of what I ordered so I'm going to have to try something else, I'll check out minibike ones. Thanks.

how exactly did you do the drive hub mod? did you just drill holes in the sprocket and hub? does anyone know of any negative effects that could result from this? Im thinking of doing this and just want some more info before i start. thanks

Ah yeah, I saw that too but forgot to go back and see if there was any progress, looks like a real beasty.

I didn't drill the sprocket, I ground off the rivets that held on those square pegs (that go inside the rubber drive thingy), then lined the sprocket up against the back of the drive hub, marked through the old rivet holes, drilled and bolted. It's made it much more responsive, every other 3 wheeler has a direct drive so I doubt it can be that bad.

Did a few more bits on the bike today. Took off the foot rest and cut out the middle section turned it and re-welded it so the foot pegs are about 2 inches lower. Feels much better - no more knees under the armpits.

Also made up a new chain tensioner, the pit bike one just pushed the chain up against the bottom of the swingarm. This way it lifts it slightly and stops any chain drag on top.

Working on an adjustable silencer baffle now, so I can turn the volume up and down :)

Only done a few little jobs on it recently.
Got the catch for the sliding seat figured out:

Made a temporary extension for the brake cable - next big part of the project's going to be a hand and foot operated rear hydraulic disc brake setup. Just searching for the right parts for it at the moment.

Had to re-do the direct drive hub today, bolts kept coming loose, and still trying to figure out how best to do the adjustable exhaust volume.
I'll keep you posted. :-)

I found a new switch for my NOS headlight but I cant find the rubber grommet that seals it to the top of the headlight, anyone got one they can sell me - it's the same on all the ATC90, 110, 185 and 200 models with the switch on top of the headlight. :-)

Got a few more bits done on the 70 recently so must be time for an update.
Headlight brackets made and the headlight on. New Maier rear plastics, (on but need to rebuild the sliding seat catch as it's a different shape underneath). Complete new hydraulic hand operated rear quad disc brake system on and working.

Time for an update to this build. The swingarm broke recently so I pulled it off to repair it but it was covered in cracks from metal fatigue so I decided to rebuild it better and stronger.

All the welds around the swinger mounts were also cracked so I re-welded and added some strengthening.

Extended the subframe so it works as a wheelie bar

Had to re-weld one of the studs on the brake disk holder that I made out of the old 70 brake drum
