Newbie with at TTR 90 questions

Recommended Posts

Hi, tr4boy here...

First post!

Just getting back into trail riding with my sons. My youngest has a 04 TTR 90 that we bought used. It had been sitting unused for about 6 months before we bought it. It seems to be idling fast and it keeps pushing fuel out the overflow. Is there any reason that those two symptoms might be related? Any ideas on how I should go about fixing it? I'm wondering if the six month vacation is causing the float to stick...

Secondly, anything to watch out for on these bikes? So far it seems to be a pretty slick little machine (except for the problems noted above.

I saw the ttr90 mod sticky...any other good advice on modification / repair information sources?

Also, any advice on where to get discount Yamaha factory parts? I expect we'll see a few crashes over the next couple of months?

Thanks in advance! Looks to be a great site!

to turn the idle down turn the idle screw counterclockwise and up clockwise. and the reason that gas is going out the over flow is because the floats are messed up. just gotta readjust the floats.

u can get parts on ebay but i dont think that your little son withh crash that bad...

What you'll need to replace all depends on how hard he rides and how big he is. My son rides the piss outta his, and all he's ever broke is the footpegs. They are weak, and catch a lot on these short bikes. They bend pretty quick, but don't break off 'til you're really hard on them. Bent the bars a good bit too, but like I said, he rides hard. When my next son moves up to it this fall or next spring, it'll hold up just fine, as he doesn't ride nearly as hard. Yet anyways :thumbsup:

I wouldn't jump to adjusting the floats right away, they are more than likely fine. Look first for a piece of debris between the float valve and its seat, often a piece of fuel line or plastic from the tank will get wedged in there. It is hard to see in there, but flush the area with carb cleaner, then peak with a flashlight. While you are at it clean the whole carb well as it is probably full of varnish. :thumbsup:
