Hi i have just bought me a Buell M2 1999 mod,, The bike is surging and pufs/backfire in the carb a lot. I have tried all the tip in carb mods and have rebuild the carb 2 times.ihave replaced the intake seals and exhaust seals. It has a KN filter and Hines exhaust.. Main 200 sec 45 and 2.5 pilot turn.. Do anyone have a tip what to do further?? | ||

Thank you for the reply, i lent my friends one and tried to change it, sorry no change in behavior  .. Maybe it could be the ignition,, do anyone know how to check the timing on this one? | ||

Paal, post some pictures of the bike. Particularly a close-up of the carb area. Give some more background on the bike, is it a stock/original setup? It still sounds like there could be a leak somewhere in the intake. | ||

Hi, I found that the intake valve at the top is not sealed properly. Engine disassembled and neatly winter work from now on..  | ||

Just out of curiosity, how did you figure that out? | ||

you take out the spark plug, connect the compressed air in the plug hole(one bar) when the engine is at top comp center,, then you have to listen in the air intake and exhaust side .. if the air leaks out you have a bad valve.. Mine where leaking a lot at cyl 2 |
