***this is a special deal because the cylinder skirt was cracked in shipping. you'll need to cut off the cracked section of the skirt or the entire skirt before running it. the cool thing is that you can totally still rip with the skirt removed!! cheap cheap cheap so no returns! sorry! ***
here at long last is the yamaha QT50 yamahopper kit! it's a 70cc 45.5mm cast iron kit. originally made for the yamaha STING SG50, this actually fits perfectly on yamahopper QT50, TRI ZINGER YT60, TOWNY MJ50 and i believe the PW50 as well.
comes with everything pictured, cylinder, piston, ring, wrist pin, clips and gasket set.
get a replacement piston here!
get replacement gaskets here!
get replacement ring here!
get a hi compression head here! If you want to use this head, be sure your spark plug is the correct model. this head uses short plugs like these. do not use the wrong plug length AND check and recheck your squish and the spacing before you run this head with this setup. or suffer the consequences. the stock head is totally usable on this setup as well, it is all in your hands, don't destroy your new kit. check everything out before you run it and destroy it. if you don't have a lot of experience with spacing things out use the stock head for now.
also probably a good idea to read this thread to get some more ideas on spacing and necessary modifications.
