hi everyone
my name is paul and i'm new on here, just registered, but been using this brilliant site for a week or two for some very useful information.
iv'e just bought my second berg a 2002 fs650, i had a 2003 fs650 about 2 years ago and never had a problem with it then sold it and bought a r1, and regretted it ever since. so bought another one.
but this 2002 i've bought is driving me insane i've had the bike about 3 weeks and have had it running for 2 minutes, i've put a newly rewind stator on from motoplat (sparks a very helpful guy), i've set the valves 1/8 turn, and the decomp as the manual says but still wont start, and i've been in the garage down to my undies kicking the crap out of it, there is no estart just kick
i took the cam cover off today to see if there was any physical damage i could see but there is'nt, but when i've tried to turn the engine with the kick start i here a hissing sound on compression stroke, all the valves are closed as there is no rockers to operate the valves, i put all my weight on the kick start and it hisses like there is air escaping from one of the valves then it turns on the down stroke and then becomes stiff and hisses again on the up stroke.
is this normal to have a little leak of air on the valves or should they be air tight so i shouldn't be able to turn the engine at all when all valves are shut. i'm thinking bent valve but don't want to take the head off if it is normal. or have i missed something else, i've set the mixture screw on the carb 2 turns out and had a play with the idle screw but is back in original position.
any help would be gratefully received
cheers paul
