Excellent video. Fixing buy a bbr big bore myself for my childhood dirtbike. Got it new in 1992 figured it was time for a refresh. Starts first kick still but smokes like a freight train
There's only 2 ways oil can get into the combustion chamber, rings or valve guide seals. So be sure to replace the seals and check the ring fit in the new cylinder before tearing down your motor. Cheers.

I need to slap a 100 motor in my 80
Where can I find the tool you used to spin the valves to create the proper valve seat?
I made it. It's a piece of 3/8" round stock. I drilled a hole down the middle using a mini lathe and added a set screw to hold the valve in place.
@@ronporteous1411 thank you sir!
@@ronporteous1411 that is brilliant and simple 👍🏽🇺🇸
