Just got the old thumb out my ass yesterday and all valve play was fine, except both left exhaust valves coming out at .30mm. this leads me to belive those valve seats are just plain old coked up, maybe left carb float sits a smidge higher?
Havent actually adjusted for that since the bike was new.
First plan is to run the engine fully warm, then blow some water mist through the left pot and see if it coughs out some black stuff. Remeasure. If no improvement, inspect fuel level and reset the carb floats. Valve play shouldnt Increase, and if i reshim this, then go about looking at fuelmixture which might burn off the coke again im just gonna have two tight valves..
Might try and mix the water spray im gonna run through the engine with some e85 for greater effect. We dont have seafoam or magic snakestuff like that in Sweden, otherwise i would have tried it.
