TRX 250 R ?s... lot's of ?s...

[biskit134]

I just picked up an 89. I got some questions. Gas is running out of the overflow tube. I think maybe the floats. I don't know. When I turn the gas off, it quits. Any ideas?

Two, when I nail it, the front goes skyward, hard. Then when it gets up on the port, it falls on it face. Kinda funky considering it will roll the tires over on asphalt.
Any ideas?

Three, it is kinda hard to shift. Any ideas?

Four, why won't my kill switch work? I gotta stall it to get it to stop running...

Here is what I know is done...

Paul Turner prepped head.
Paul Turner #6 pipe.
FMF silencer.
Ported.
Was told it has a stock bore...
+2 swingarm, +4 Arms and Axle (all freakin' chrome... this thing is pimpin')

This thing is badass, but not running near like it should. Thanks for your help, just when I go and get versed on the T4, I go and buy an R...

1. Yes your float is off... you shoult set the float, if that does not work, get a new float and needle, then you wil fix the over flowing carb.

2. Jetting is off, you need to go bigger on the main jet.

3. Your shift forks are prolly a little worn, change the oil and see if there metal pieces in it. Really nothing to worry about that it shifts hard... but check the oil... thats bad if thers metal shaving in it...

Congratulations on the purchase :-) Sounds like a real nice R. What type of riding do you plan on doing with it? From what I can tell from your list of mods, it's difficult to make recommendations as some of the components don't really match up. For example, you have a Type 6, which is a very low end woods pipe (best pipe for that type of riding) and then you have a +2 swing arm. Doesn't really add up; see what I'm saying?

1.) Definitely check your float level. Sounds like it might be stuck. Also, since you're already having problems with the stock carb, I'd recommend to upgrade to a Keihin PWK series carb. The stocker sucks, imo. It's too small for one and difficult to jet compared to the PWK. It'll save you some headaches now and later on. Depending on the riding that you do depends on what size to get.

2.) This is most likely due to the Type 6. Like I stated above, it is a very, very low end woods pipe and has NO top end whatsoever, which explains why it's falling on it's face at higher RPM's/speeds.

3.) Can you explain this a little more. What exactly do you mean by hard to shift? Like it won't go into gear, or it requires more force than you thought it would to shift?

4.) Are you running a stock style switch or aftermarket?

You also need to check your jetting. Check out this link, it has all of the required information to do so: Keihin Carburetion Jetting - D.R.I Tech Support Center

Thanks guys...

I bought it in this configuration. I bought it thinking I might drag it, so the extended chrome swinger appealed to me. It has an aftermarket switch. I got it from the second owner who MX'd it a while... When I say hard to shift, it is hard to get it out of one gear and into the other, neutral is hard to find too. 4,5,6 seem to be ok... and I found out a little while ago that it has got good top end. It falls down in first and second.

[Bad Ass Honda 250r]

well..... theres gotta be some shifting part thats worn out.... i know neutral is hard to find on mine.... but not every other gear... I still think your jetting is off.... do you know how to jet a 2-stroke quad???

[biskit134]

Uh, no...lol. ALL my experience is with thumpers. I did have a badass T4 310, but never had to mess with the carb...

What he said


Your shifting issues are more than likely caused by a badly groved clutch basket. Take your basket off and file the ears smooth, as long as its not too bad it'll work for a summer or two.
