so, after a lot of work and trial and error including valve clearances and more, i cannot get the bike to start with ease, it takes a while with me covering the air filter to form a vacuum for it to start up, and even then it kicks into a high rpm until a few seconds after, this problem is then resolved by a warmed up engine but when the throttle is twisted the rpm seems to stick for a longer amount of time.
I suspect a carb problem but thought id ask a few more owners for advice.
