Looking for engine parts for Yamaha GPX338G (free air engine)

[jfpsteve]

I am rebuilding a 1975 GPX338G free air engine. Need a bottom end for my engine. Yamaha free air 340, 440, Sno Jet Thunder Jet 340 ,440 and a few others are the same. Any parts out there available? Mainly need crank but would like a complete bottom end if available. Thanks.

Be careful the bottom half of the case is the same for a 340 or a 440, the crank also but the top case is different for the larger 440 cylinders. I may have a 440 crankcase with crank.

You should post in the want ads at the bottom of the forum page. You would have better results.

while the bottom half of the case is the same for 338 and 433 never miss match cases they are a set and finish line bored that way ...........do you need a crank or crank and cases? do you have a crank that just needs to be rebuilt if so I rebuild them
