Hi guys , old member returning for some help . I have a 2003 b1200s , this is my problem . bike was running fine , parked it for a couple days , went to start it up and white grey smoke bellowed from the exhaust. Ran just a minute and died. I had heard about the fuel pet cock going bad . So pulled the tank , air box full of fuel,plugs fouled. Cleaned the carbs ,put in new plugs and air filter,rebuilt petcock...now this is the bad part, went to start her up ran for about 15 seconds and the smoke starts bellowing again. stops running I guess fouled the plugs..was this caused by fuel being left in the cylinder or do I have a much bigger problem.... the bike has never given me any trouble until now..it has always been adult ridden ,,by me only, and no I don't loan her out. have any of you had a problem like this ???? I have searched on the internet for any help , none to be found. If anyone can help me , thanks in ADVANCE Gary P n.c.
