Here we have a set of cylinders original for the 1971 SL 338 marked 337cc. These have good smooth STD bores that have been cleaned and honed. All the gasket surfaces were scraped clean and they also have been glass bead blasted so they look very nice also. Shipping will be $15 in the US but more to ship internationally. Thanks

Will gladly combine shipping on multiple auctions won.

I also have many other yamaha snowmobile parts listed in my e-bay store, if you're looking for anything specific send me a message.
