so long story short….i got this 85 trx125 from a buddy of mine. it had the infamous no spark problem, which was fixed by replacing the cdi, coil and spark plug. it fires up great now……until a couple months ago, the motor started knocking. im 90% sure its piston slap.

ive heard that if you pull the motor and take the head and piston off, some guys online will machine it and send it back with all the necessary parts to put it back on. after some heavy googling, i havent found a reliable source that would do it. so any reliable good shops to do it would be awesome. i have no problem pulling the motor itself. but i dont have the tools to machine stuff down. and what about cost? this is obviously a budget build.

would a crate used motor be cheaper?

in other news….its for sale if anyone in texas wants to buy it
