[QUOTE="Smerkal, post: 990354, member: 29283"] Compression is 85-88 all across the board. I have no reason to suspect a mechanical issue. Bike Only has 13k miles on it. I am unable to isolate it to a single or pair of cylinders either. I can disconnect the injectors one at a time, inducing a dead miss on that one cylinder, but the other three continue to burble, and it's the same all across. The rpm drop on each cylinder is identical as well. Enrichening with propane/ether smooths it out some but not completely. Perhaps they just do this? Can others confirm or deny? It drives me nuts especially edging slow in first such as in a parking lot because the bike surges. [/QUOTE]
