Lately any time I stop the eng dies,unless I keep it above 1000rpms. It's becoming very dangerous to ride. Not every time but most of the time.Gas cap vent does not effect it.I have 45.000 on it. this is getting worse. Dealer can find no problem when I take it in.Couple of months ago was going home from my bros house about 15 miles, died at every light about 15 times, next day got it serviced they found no problem. This weekend went about 200 miles it started around 50 miles into ride, dies almost every time I stopped. No clutch drag.Top grade of gas , full or down makes no difference.Bike is going back to the dealer because it has become very dangerous to ride.Any info would be great.No heat problem either. Daryl

Hi,i am not overly familiar with these but it sounds very much to me like a carb problem.and very likely a carb balance problem(if the bike has carbs),the problem being that as the linkages and internal parts of the carb wears the carbs will be getting an imbalanced fuel and air load,its takes very little for the carbs to go out of sync,but when they do it will cause erratic running particularly at idle,or when as is your case coming down off the throttle to an idle,there will be isufficent mixture or fuel in the system to let the bike keep running,carb imbalance normally affects the slow speed circuit in the carbs more noticeably because of the low rpm,not so noticeable at high rpm as the carbs are getting plenty of fuel.If the bike is injected then it maybe that the butterflys in the throttle bodies have suffered the same fate,the linkages may have worn slightly allowing an imbalance to occur,or if injected(again)the fuel injection may need remapping,.road conditions are very hard to replicate in a workshop environment and your problem seems to go away once the mechanic touches the bike(its almost like the bike knows it is at the doctors),i would put my guess on the carbs being out of sync,get the dealer to put a set of gauges on it and see what happens,the adjustment only has to be out by 1/64 of a turn to be wrong...hope this helps..let me know how you get on...cheers..ian
