ok i have a trx 250r engine and i split the case and im going through everything what do i need to do to make the thing a absolute beast! But still have total reliability!! im building it all and stuff like that so what do i need to do as far as cranks rods pistons bore size carb port and polishing pipe clutch reeds best kind of seals to put in the bike anything and everything!!! i am wanting a lot of tourque and top speed also But please keep in mind Reliability is a big factor on this bike! so tell me what would be the best set up for me.. i am enduro racing and MX ( i dont have alot of cash to throw around when it breakes apart) i do know about 2 strokes and everything like that and i have no problem replacing pistons and rings but just no major stuff like cranks going out breaking rods and stuff! so any help would be greatly appreciated
