I recently picked up a 2001 TTR 90. It was missing the airbox so I picked one up on ebay. The bike runs pretty good without the airbox installed but will not accelarate with the airbox in place. I had the carb off already and cleaned it out, it was pretty clean in there already. The float seat is bad I think, so gas drips out the overflow tube. I have looked all over for a rebuild kit and cannot find one. I found jets and parts but not an actual kit. Is there such a thing for this bike?
Also there is a vent tube or something on top of the airbox. I have no idea where this goes. I thought they usually went to somewhere on the motor but I cannot find a spot anywhere on this thing. Looked through the manual but nothing is really clear.
Any help would be appreciated.
