Trx90 engine

[hrc450er]

I have an 02 90 that the piston broke on. Cylinder could be over bored and be fine but the crank has a few niks in it. For what i could buy a new oem crank,bore cylinder, and buy new piston for i could buy a lifan or some other motor for. But i dont know if they will bolt in easily or not with little mods. Boy is gonna be 3 so i dont need a race engine for a few years

Terry at Firepowerminis could prob fix your motor for about the same as buying a new Lifan motor, keep the Honda motor
