I adjusted my valves last night and started the bike today to find this... Idles great with maybe a very faint grey puffs of smoke from the exhaust but when you give it throttle and let off it will rev with no smoke but when it comes back down it puffs a small cloud of light grey smoke. It didn't do this before and I'd rather not run it if its too lean... Thanks guys! I'll be back in about 5 hours if I don't respond right away.
