Here's the four stroke class. I'm goofy guy in green. They tried to line us up in rows of two but the other guys didn't catch on so we just formed a line haha

Nice job!!! You got the holeshot!!!!

[plevib]

Thanks! That was the first and last time I was in the lead that race haha. ... hey does anyone know how to move this thread out of new member discussion?

Also here is a longer video after some carb tuning. After I took this video I got it to idle quite nicely. Good throttle response off the idle. Obviously I don't know how it runs under a load yet, but all of my fears (and people's doubt) about my home engineered intake are silenced! I'm very pleased it turned out so nicely!

Also on a side note, this thing is gonna be a definite sleeper. I'll look pretty stock to someone who doesn't know their trikes, and it's actually pretty quiet.

What I personally do about threads is to update the first post with the link to the latest thread on the subject, but keep this one open for those stuck in this section yet. Basically the same thread in parallel. The other option is to hit up an Admin and request it.

I figured the intake would work, hopefully the longer intake tube gives the better bottom end grunt like other online forums suggest (for cars). It might make less HP overall with the longer intake, but the TQ will be higher in the lower RPM range, but this is purely what I have read. Should be a fun wheelie machine, or hard launcher.

Ok I'll try talking to someone. And I'm glad you had faith in my intake cuz I didn't haha. ... and yup, it'll be totally opposite to the 250r that it was before haha. ...... all low end power. I think it'll love hills!

I did a little fab work tonight. I modified the shifter. Now it's very comfortable. I also created a clutch cable bracket. On the xl the bracket is the frame so I had to make one for my application.





All I'd have to do is put a chain on it and I could ride it! But alas, I will do the right thing and make skid plates and paint it first. :/ I would say I'll have skid plates made and hopefully it all painted this weekend. Then next weekend, reassembly, work out any kinks, and ride the crap out of it! That's my goal

[ps2fixer]

Well I knew it would atleast run, I have seen some toyota engines with intake tubes 9 inches + per cyl, then they hook into a main tube that spans about a foot or so long before the throttle plate. Fuel injection vs carb blah blah, not a massive crazy difference really, fuel still gets in the engine and fires to make it run. I do think the carb car engines are shorter intake tubes though, so should be interesting to hear the ride report, hopefuly peak TQ isn't at 1200 RPM lol.

You could throw one of those vortex things into the inlet if you do have fuel suspension issues, but I would just give it a go how it is, it may be fine.

Vortex things? Never heard of that. What does it do?





One skid plate done. Hopefully I'll get the other finished tonight but probably not. As usual I didn't get as much done this weekend as I wanted to..... but my Saturday was spend driving to Mr twisted's store to trade the 250r motor and exhaust for a 200x bottom end, a rusty dg exhaust for a 200x, a 350x headlight shell (I'll show you guys what I have in mind with that later), and most of a 1980 xl185 (cuz he was gonna put it on the street for someone to take). I'm tickled pink with the trade! Plus I got to check out some of his collection. Holy cow! That man has some sick trikes! Anywho, back to work!

Are you going to leave the front fender sitting on the tire? Nice build!

[plevib]

Thanks! No, so there's that guide for the front brake line in the fender, and there's a screw in the fender holding that part on, the nut was just spinning in the hole. So I just left it there.



Front skid plate done. Off to paint!

[plevib]

Looking sweet

Vortex things? Never heard of that. What does ?

They're a very simple helix style gadget, branded as hyclone I think, that gets installed in the intake tract that puts the moving air flow into a spin. Similar in concept to some vacuum cleaners on the market, and air intake pre cleaners as fitted to some trucks.

The concept is the air is made to spiral along the air flow path either to throw particles away from the the final destination of the air flow (in the case of a vacuum cleaner or air intake pre cleaners) or to maintain air velocity though a restriction (in the case of a hyclone intake gadget)

I'm not vouching for the validity of gadgets of this nature, I'm just suggesting you could try something like this if fuel suspension becomes a problem as a result of the limitations of your intake.

But like I said, give your set up a go, it may work just fine as is.

[plevib]

Hmmm interesting. I'll keep it in mind if this doesn't work. But the way it sounds I'm thinking it will work well as is.

So as usual I didn't get as much done as I wanted to. I'm anxious to ride it! But I have the skid plates %100 done! I figured out chain slider mounts and finished up a few things that I just had tack welded and then I got some of it taken apart for paint. I pretty much just have to remove the triples and swing arm and then I can sand!

[plevib]

So excited! I'm putting it together tomorrow!
