I had the same exact problem with my '97... I pulled all the vent lines from tank and blew them out along with the small vent at cap. Pulled and cleaned the carbs and petcock. And definitely change the oil because it does have gas in it. I filled it up and rode 150 miles yesterday with no problems, stopping and restarting several times just to be sure. I turn my petcock to off every time I let it sit at all now. Before I left it on all the time. I never did find a definite problem but the bike is running now.bilyum said:what causes gas to leak out exhaust??? Or , what is the fix for gas leaking out exhaust pipe.?
The overflow of gas diluted the oil and flooded rear cylinder with oil and smoke was white until plug fouled. Cleaned up and excess gas burned black smoke until flooded and flaming backfire. Cleaned carbs and all vent hoses and lines from tank and bike is back running.artman said:Did the bike smoke when you rode it? If so, black or white?
