TTR-90
Does anybody know if there is any restrictors on this bike to keep in under control ... rev limiter - exhaust restriction plate . Any hidden mods that a guy can do without tearing into the motor . It is an 01 and I will probably sell it after this riding season but dont want to go overboard taking the engine apart.

There are no restrictors. It doesn't need any.:)

I bought a TTR90 for my son last July and installed a Big Gun exhaust system. It REALLY makes a difference. He rides with some older kids that have XR80's, XR100's, KX60, and one with a KX65. The TTR90 will accelerate with the best of these bikes(of course he is only seven and weighs less than the other kids), plus all the kids think the pipe sounds cool. :)
