hello all its been a long time since ive been in here ive got a 440 ltd 1981 the bike was given to me, i was told that it sat up for quite a while, well last year i started working on it, i got it running then things got a little crazy around the work place and i put the project off well now im back at it, i went out to the shop the other day and turned the engine over a couple of times and she fired up. but she started backfiring through the carbs after she warmed up, so i took off the air box and started her again it lookes like its just the left carb also looks like the bike is spitting an awful lot of oil out of the breather tube? any suggestions as how to correct the carbs? and is oil supposed to be coming out of the breather? thanks
