1982 RM465 new rebuild,Will It Start ? 

Rare and cool.i remember back in the day every one was on a yz or the new cr 480 back in those early early 80s..which makes that 465 .rare and cool

i got one aswell need to get it running, great video!

I had a Yamaha IT 465 and theres no way on earth i could use my hand to turn the engine over. If it backfired it could break your leg.I’m thinking your ideal compression is around 140-160 psi…Also a great technique i learned on starting big bore bikes…..and any two stroke bikes in fact…..turn on the gas and choke….lean the bike over till the fuel comes out if the overflow… stand the bike back up, kick slowly to compression just past top dead centre or until the compression stroke eases slightly…and THEN, give it the beans…..it always seems to work and looks pretty cool too. Good luck 🤞🏼🏁

Pulling with the pick up all ways works

Check out Swain Coatings. They can build your piston back up close to the size you need.

Air leaks are the sneaky gremlins on a two smoker.

The DG silencers are horrible for performance, I raced a rode a 82 RM465 from 2009-2013- once I replaced the DG silencer with a stock length aftermarket- wow what a difference in mid-top end!

Beautiful build. Who did you buy the tank decals through? I have a 1982 rm80 and rm125. I’m looking for better than what I have. Bought thru eBay. Seller in Australia. Not the greatest. They are bubbling. Thanks 🙏
