Complete engine is present with OEM parts carb and electronics, but I am parting it out and not selling as a package deal.
Many new OEM parts were purchased like Power valve (YPVS) main crank bearings and seals, aftermarket complete gasket set, C/S sprocket Guard, OEM rubber intake carburetor / intake manifold, PRO-X piston kit (FAT STD), and more were accumulated but never did get the cylinder sleeved or re-chromed. I recall the chrome about the exhaust port was worn through. The engine is completely disassembled/cleaned and prepped for assembly. I've been told by an engine builder for bikes that someone did a nice job porting the cylinder !
The only other thing I'd change out is 2nd gear, there was some MINOR tooth issues, but it still usable like it is.
sleeve is a ya5174 which is an L A sleeve and runs on eBay when they're listed from low one hundred's to about a buck fifty. This engine was last run in the early 2000's by me on a 86 YZ chassis, which I restored the proper 86 engine and installed it back into the original frame.
Respond by email, include location, name and phone number and I will reply when it is convenient.
