Hi ya'll
I have a 1978 xs650 "E", with bs38 carbs on it.The short version of the story so far is for a couple days i had to run without a muffler because my collector got damaged and was being repaired, on one of those days the bike started "stuttering" at highway speed, I went to a buddies house, we synched the carbs, did a little dialing, and it seemed like it was running way to lean. so I get my collector back, put the exhaust back on, it still seems lean, I go through the long process of getting my main jets just right (so i thought) and now the bike runs horribly, at about 1/3-1/2 throttle in any gear it stutters hard and more often than not dies. So heres some info on my set up: k and n pod filters, 2 into 1 reverse cone megaphone exhaust, 150 main jets, i took the pilots up .002 from stock, the carbs are clean and all that, I have my airscrew out 3/4 quarters of a turn and according to my "plug test" the jetting should be ok, the electrode and porcelain are brown with a small amount of black.
Sorry to write a novel for ya but im running out of ideas on what to do, Im going to check my coils, compression, and valves tonight just in case but I doubt those things will have to much to do with my problem. any help would be greatly appreciated.
thanks,
Jordan
