Take the cap off of the end of the air filter. Add a K&N or Uni filter. Clip the pink wire coming out of the engine to remove the limiter in 4th gear

Anything that you can do to help those little engines breathe is a big help

Clip the pink wire coming out of the engine to remove the limiter in 4th gear>> Hey i was wondering why there is a limiter on the 4th gear anyway? and if you could explain more on where this pink wire is located, i just got a 700xx and was wondering some of the same things.

powroll makes a pretty good bigbore kit for the TRX90, pair that with a good exhaust, and air filter and you should run pretty good. You can also get an aftermarket CDI that will change the timing curve a bit and increase the rev limit.
