550xp running on 20% Ethanol = Bad News

Yeah, that's what I sell them for also. so that's a legit price. List is $230 something.

Unfortunately, the full kit is the only option if it's gotta get done quick. 550 pistons are backordered til August. (not really that long). And the rings are September. Only the full kit is in stock at the moment.

Well dang, for $185 I'd pop a new top end on the thing and stay away from ethanol!

Lots of scenarios being built on speculation here.
