[QUOTE="Black Flash, post: 31908, member: 433"] I am at the moment trying hard to get the jetting right on my 600 cc Comet special. I have been kicking the bike a lot the last week believe me. With my brothers clapped out 500 I use the valvelifter to get the bike over the compression and then give it a good kick-I am 17 stone by the way- and the bike starts 8 out of 10 times. with the 600 having been completely rebuilt and not yet run in, this procedure does not work as the friction slows the engine down too much before the ignition fires. I do not know about the difference in k/s gearing between a Norton box that I use and a standard Burman box. But now when I have eased the piston over compression I let the kickstart come back to the top and slowly depress it to the bottom of the stroke just to slowly revolve the engine further. After the kickstart has returned to the top again a give it a good long kick without touching the valvelifter and the engine starts every single time. Simply because the engine spins faster by the time the spark occurs. hope that helps Bernd [/QUOTE]
