recommended oil...the conclusion...

[mjlyam850]

my 1991 klr will occasionally hesitate as it accellerates at around 4000 rpm. if i am cruising at about 65 then accelerate to overtake, the bike seems to miss a beat as i do so. it is fine after that. seems worse on fairly aggressive use of the throttle. if i gently open her up it seems fine. any ideas ?? carb or electrics. - i have the pilot screw out 1 3/4 turns. (my first post as i have only recently joined you !)

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

Thanks to everyone for your opinions on the oil. By far most seem to prefer (or have no problem with) Rotella. Special thanks to Jeff Saline for the tip on replacing the crush washer (complete with part number!!!). I always was going to change the oil every 3k, but if changing every 3k w/Bel-Ray vs Rotella only gains me minimal (if any) extra engine life, I'll go with the less expensive alternative. Thanks again for the advice! Jeremy [Non-text portions of this message have been removed]
