Sounds like it's starved for air, fuel or may have a worn plug. Hard to tell which. Check your air filter then check the plug. And maybe look at the timing. any one of the above could be the problem. Kerry

<><><><><><><><> <><><><><><><><> mjlyam850, I'll make a wild guess it's a fuel delivery issue. Since the bike is pretty old I'm gonna guess a fuel passage might be clogged just a tad OR the needle is worn an excessive amount. Might be the slide is sticking a little too. I'll bet the carb has never been apart and it just needs a little attention. Kerry suggested you check your spark plug. If you do pull it make sure you clean around it very well first. There's usually lots of stuff around the base of the plug. If you don't blow it out or somehow get it away from there it will probably fall into the combustion chamber when you remove the plug. Then you may cause more harm than good. Good luck with it. Make sure you take it one step at a time so you know what happens to performance with each change or repair you make. Oh, and welcome to the list. Best, Jeff Saline ABC # 4412 South Dakota Airmarshal Airheads Beemer Club www.airheads.org The Beautiful Black Hills of South Dakota 75 R90/6, 03 KLR650, 79 R100RT
