Used stock cylinder head for yamaha qt50 mopeds nopeds coughscooterscough

custom cut squish 45.5mm head specifically designed for the yamaha QT50/YT60/SG50/MJ50 malossi kit! that's right, the squish angle is spot on for the unique dome shape of the malossi piston.

NOTE! due to the unique shape of the malossi kit piston, you will need some spark plug index washers to space the tip of the plug away from the dome of the piston. we found that the thickest of the index washers works well!

NOTE! this head uses standard short thread plugs.

***there is some very small pitting from the initial casting of the heads. it will not affect the performance do not fret***

for malossi kit part # 31 8007

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 originally made for the yamaha STING SG50, this actually fits perfectly on yamahopper QT50, TRI ZINGER YT60, TOWNY MJ50 and i believe the PW50 as well.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 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.
