Engine and Clutch

Engine and Clutch

One of the typical stumbling bike when reviving a vintage RD350 is errant engine oil leaks. Your engine gaskets are 40 years old, well past their useable service life. When brought back to the land of the living, those old seals and gaskets are bound to yield to your vintage Yamaha 2-stroke’s pressure. As the pace gets frenetic, the situation will only get worse. Luckily, Mikes XS has what you need to right the ship. We stock RD350 and RD400 overhaul gasket sets and engine oil seal kits, so you can renew these critical vintage Yamaha engine components.

Mikes XS is also a great place to find new OEM-type replacement parts for Yamaha RDs. We have the RD250, RD350 and RD400 spark plugs, kick-start lever, kick-start rubber, and kickstarter rebuild kit. And while you have those vintage Yamaha engine cases split, check the condition of your clutch and renew worn or wearing parts. Mikes XS carries RD350 clutch friction plates and clutch spring sets to get your Yamaha 2-stroke shifting smoothly, as its engineers intended.
