Hey all,

Recently got an 2002 Eton 90cc 2 stroke ATV. Previous owner could not get it to run and just wanted it gone. Cleaned the carb, put a battery in and it fired right up. Not knowing its history I pre-mixed the fuel, pulled the injection line to see if the pump was working. Turns out the injection wasn't working and that explained the rattle coming from the engine.

Did a quick compression test and found 90 psi ... low! Pulled the clyinder and found the piston/ring toast and the cylinder scored pretty bad.

Now I need a little help determining some replacement parts. I am not really interested in mods, just want to get it running good. There seems to be a crazy amount of cylinder/piston kits online available .... many 52 or 54 mm bore, however measuring my existing it is only 50mm. The pin is a 12mm. Crank seems to be fine ... might to a tiny bit of radial play .... if i had to guess by feel, maybe .002-.003"

Have found one kit that I am interested in it says "CYLINDER KIT 90cc 12mm JOG Yamaha Minarelli Engines" .... $49.99. Will this work for me or is it just a waste of money?

Thanks
