300R have a freindly powerband ?

[Huffa]

I have a 300R, didn't ride it much at all yet, maybe 20 minutes total since I got it 5 months ago or so.

I took it out tonight just for 10 minutes or so and noted that it is jetted way too rich (a blubbery pig) and seems geared way too tall, I did not check the gearing yet but that is my impression of it as it stands right now.

Anyways, I'm just wondering if once I have the jetting sorted out (it has 38 or 39mm carb on) and put fresh reeds in, that it will help broaden the powerband and smooth it out some because the way it is now, it is entirely too peaky to trail ride.

If it doesn't change the personality of it enough, my frame of mind right now is to sell it because I just don't want to be riding a guided missle through the woods. I'd rather have a "freindly" 350X for PA woods, this thing seems more of a desert machine to me or a pure bred motoxer and I don't think the big carb is helping with a smoother low end either.

I guess it never was intended for trail riding so I won't be dissapointed if the motor can not be "tamed" to my liking.


So this whole post is mainly asking all 300R guys if they take theirs in tight trails and wanting to know the true personality of the engine. When and if you give comments, please let me know how your 300 is set up reguarding the size carb,reeds,pipe,etc,etc

BTW........My top end only has about 4-6 hours on it so it's quite fresh. It was rebuilt by a Honda mechanic, which was the guy that owned it from new before me.

[edog]

Sounds like you have your hands full.:lol:

Time to down grade.:D

Try riding it for a Hour and see if the problem still rearing it's ugly head.

Try selling it and get a stock 85 or 86 250R.You would like the power.

Well yea, right now I do, I just want to know what to expect when the engine IS running correct.

I rode a Z a few months back and the power was NOTHING like this beast. That Z was great on the trails powerwise, this R is not simular in power what so ever, seems to have gobs more.

I want to be fair and give it a chance though and am just curious what other owners are using them for.

Up your way in the winter on the wide open lake, this thing would rock!

I don't have anything like that down my way though :(

Edog, I'm not going to go thru all that and downgrade 50CC. I'd sooner have a 350X then buy another one of these but don't get me wrong, they are great machines, I tend to like more tractable motors though and am not concern with just how quick the machine is.

[SYKO]

mine had half a piston blown away it was geared high and I LOVED IT!!! it would stand up in a heart beat! and I had a blast through trails wither puttin around or flying, the power is not like my light stitch 85 it jsut felt even all the way through had great low end/mid/and top, the engine i found out was on its second to last bore 34 keihn carb and a jemco pipe with uni filter it needed to be tuned better becouse it fouled plugs like mad, but that may have had something to do with half the piston missin lol that tends to mke things run differntly.

not its being bored fgr the last bore piston 1 over thats alos teflon/ceremic coated I might no some light porting, bigger carb going to my mikuni 38 and the same boysen reeds that came out so it should be ready to hit then!!

[Huffa]

the power is not like my light stitch 85 it jsut felt even all the way through had great low end/mid/and top,

This thing IS pretty much like a light switch too and I'm hoping I can get it fairly even like you state yours is.

Having power that is a switch is no fun over slippery rocks, logs, moss ......stuff like that.

[chris200x]

If that bigger carb gives top end why not put the stock carb back on it. (if you have it) That may be a good starting point. Then go to a smaller front sprocket to gear it down.

I don't think a 20 minute ride is enough to really get a feel for the machine. try some changes (drastic if needed) then take it out for a day on the trails. AND GET RID OF THAT DAMN TWIST THROTTLE!!!

[firefirefire90]

don't try to make a beast into a piddler. Just buy another trike and let someone else enjoy the trike as it is.

and BTW

a stock tri-Z is hardly a comparison for a fairly fresh 300R

[deathman53]

why get rid of the twistie?, I love them. Once you get used to them, its hard to ride anything else. Get the jetting more correct and remember, its not just the main jet, your needle and pilot have alot more to do with 1/4- 3/4 throttle then does the main!!!! My 250r was kinda peaky, I leaned the needle and it was quite different, now it has low end to it, not just screaming mid-top end. If you get softer reeds, you will have more low end. There is many things you can do to improve it.

[SYKO]

you need to ride it ALOT more than 20 mins, a 2 stroke is totally differnt than any 4 stroke, they getting used to but can be fun in any terrein I love my 300 it works great anywhere

[cr480r]

It may just be the way it was ported... or the pipe... or the carb tuning... has the flywheel been cut down? I would put a stockish top-end on the bike before I sold it...

[Huffa]

I don't have the stock carb.

I'm not trying to tame it by less power, I just want more USEABLE power, that's all.

I know I'm jumping the gun a bit on judgement of it and do beleive it can be made more rideable, I'm just anxious to hear what type of power other 300R guys have that do have one in perfect state of tune.

There are certain body english postions on a trike that a twist throttle puts your wrist at an odd postion, so that's coming off for sure.

Years and years ago I rode one for a while with the twist, just couldn't stand it. It may very well be the hot set up for some but me, naaah, no can do, it must come off!

[200xman]

If you go to a stock carb the main jet that comes with the kit is a #135 for the 83-84 carb. If you PM me your address I can send you a copy of the 300 kit instructions if interested. My 300 in an 81 frame just pulls like mad. Plenty of power down low and hauls when you get on it.

I like the twist on some machines and hate it on others... But if it feels akward then its definately not safe...

I completely forgot!!! ...........it has a heavier flywheel on so that should help it "thump" along a bit better then a stocker!

NO WAY, why would I put a stock 250 jug on when this 300 only has 4-5 hours on it, that would be a total waste of time and money.

I think the huge carb may be the main culprit but I MUST inspect the reeds too.

[Tri-ZNate]

2 words, plug chop. Clear it out some and it will probably act better. What are you mixing it at as well?

Thanks for the offer but I have the directions and even the 300 kit box yet.

I'll check and see what jets are in it now.

You bring up another good point, it has Golden Spectro in at 25-1 which I feel is too rich with oil. The other owner did that and always ran it that way.

The gas is 5 months old and was fresh when i bought it. Time to change it for sure.

I'd think I can safely run it at 40-1 but don't have current knowlege of the newer two stroke oils that are outnow a days. With some oils even a leaner ratio I bet!

[Tri-ZNate]

wow 25:1? yeah lean it out to about 40:1 and I'll bet it will cure all your ailes

Almost any major brand is good stuff, I stick to Klotz and Amsoil.

Your R running now wheeliepop ?

[Tri-ZNate]

Yep always ran just need stuff so it could move. Basically a fooked up swingarm bolt has kept me from riding it

[Louis Mielke]

dude 32:1 in the air-cooled bikes in my honest opinion but whatever you want to do.

[BigGreenMachine]

32:1 and jet it right for that big carb or an 85 R carb thats jetted right.

As for power is should have a broader powerband then the 250 since thats what a bigbore does. (more everywhere)

The flywheel weight will make it a great trail bike.

22 inch tires would be a good idea too if your trails are as rugged as you make them out to be.

Sort that bike out and ride it, if you don't have the patience for that then sell it to someone that does.

[MO dx]

never liked 2strokes for hard trail blazin but thats my opinion. They were made for runnin not puttin.

[Huffa]

That depends highly on the type oil your using and the CC of the machine.

A smaller engine like a high strung 125 takes a richer mix because you are revving the snot out of it.

There are guys that run 60-1, 70-1 EVEN a 100-1 with no problem but I can't recall what size machines or oil they were using.

With most oils, from what I am use to at the moment, 40-1 is perfectly safe.

[Huffa]

Not so any more though, think of what trials (not trail) bikes do, they putt around at LESS then a walking pace and have gobs of useable power.

.......but yea, pertaining to 80's machines, 2 strokes are not real good putters.

[Mosh]

Sell it and buy a new armchair:lol:

[MO dx]

I guess your right thats the era I tried a few of them. Thats why I stuck to the dx and sx for the trail ridin style I like. Hard to teach a old dog new tricks

[Dammit!]

Tuning and gearing. If you get it jetted right, use an appropriate premix, make sure the spark is good and you have it geared right for whatever riding you're doing, it should be fine.

2-strokes usually end up being peaky because they're just not tuned right. My R used to be extremely peaky but that was my own fault. I got the main dialed in perfect, got the needle to what I felt was "close enough" and left it like that for a while. Basically I got lazy and didn't finish the job. Once I got off my butt and finished tuning it, the light switch effect pretty much disappeared and I had a lot more low end and mid-range power.

A little too rich or too lean on the needle will make it feel like a light switch because you're basically running in a throttle range where it's out of tune (1/4 to 2/3 throttle), then it hits the main that's dialed in right and all of a sudden it has a ton of power. The needle is also affected by the taper, not just the needle position. If you can't get it dialed in right, you might have to consider using a different needle from what's in there now.

[ceaserthethird]

Trail rider here ... I have a water pumper 250R

I don't get out of 1st & 2nd Gear Pretty tight and rocky area's ...

I' say put the Stock Carb on or a 85-86 250R carb .

That's exactly how it is behaving and agree with all what your saying, I hope your right !!

Thanks Dammit, I feel a little better now.

[slothminx]

Some people love em on a 3 wheeler, But I just wouldnt be able to ride with one and have any kinda of precise control over technical trails. Oh..im talking about a twist throttle :D. Swap a thumb one onto it and see what its like to ride then.

Oh and about the Z and 300R power, Id like to bet that its probably pretty similar, standard 84R isnt near a Z's getup and go.

[nate b]

when I had my 84, I put a brand new honda 300 kit on it, stock pipe,carb, 15t front sprocket, 20" tires and it was an awesome trail machine, the torque and power band was great.

My bike has a 36mm pwk a cobra pipe and a 300r kit I use 20:1 amsoil dominator and 110 octane leaded fuel the carb has perfect jetting and it runs perfect I use it for drag racing. I also drag raced my 250 motor with same fuel ,same oil ,and ratio with a stock carb that engine is still perfect it is going in my 83r.
Jetting is the key no matter the oil ratio get it right and your bike will wake up big time on top and bottom end.

[dufrain]

My 300 in the 82 frame has a ton of low end ,it will definately snap the wheel up but it pulls down low great.Mine has the stock pipe with a dg silencer,along with a stock 86r carb and boyeson reeds.The stock jetting is pretty close. I run Klotz r50 at 32:1.That 38mm may not be keeping the air velocity up being that big along with the low speed jetting being off some,causing a little hesitation making it feel peaky.Try a stock 85 or 86 carb.

[fla 2-stroke]

my 83r with 300 kit that is 80 over runs awesome.stock carb, bassini pipe,full airbox.I run amsoil dominator 40-1. never fouls plugs and has great low,mid and top.very smooth power delivery.It has more low end than my 86r.I also believe it will out top end it.overall it is a great bike.

[Huffa]

Thanks guys, great info.

The previous owner was just more concerned with top end (he drag raced it) and not how ridable it can be.

I'd rather sacrafice top end and have great low and mid range.

Mine has ..........

DG pipe and silencer
K&N filter
Boyeson reeds with reed block, I think ?
38 or 39 Mikuni
fresh top end
heavier flywheel

rewound stator with 200X rectifier on it (must of rode at night often ? )

Man, I didn't even check if the airbox cover is on, can't even recall if it has one or not, now that I think of it. That can lean it out quite a bit right there, by taking it off, if it is on that is? :D

[Bryan Raffa]

guess you were serious about makeing it your daily rider!! Im gald ya did,, it needs to be rode!

[Huffa]

guess you were serious about makeing it your daily rider!! Im gald ya did,, it needs to be rode!

Yea, I'm sick of just looking at it and it's actually not good (motor wise) for them to just leave set.

You ever ride a air cooled R Raffa?

If not, next time we meet up we will switch for a bit, if ya don't mind.

I'm of course going to take the fairing and rear fender skirts off, it makes the machine look so huge.

Hate to take the vintage stickers off but he has the thing way over stickerd, looks too busy. The front fender I'll leave them on and just get another fender, that one is worn thru anyway. The rear they are all coming off.

I want to relocate the light rectifier too, that's a 1/2 fast stupid place he put it, I'll make a bracket up or something, mount it under the tank on frame I guess?

.......get the right bolts for the triple clamps also. Weird, the guy works at a Honda shop for over 20 years, ya think everything would be thought out perfect on the thing with having access to all the machines he does :rolleyes:
