low power, slight hiccup thru the carbs, and one fouled plug?
Okay, so it's time to figure out just what is wrong with my bike. (2000 M750, aftermarket high pipes, aftermarket dynacoils & pod filters) I bought the bike used & untaken care of, for the most part. It has a hiccup throught the carb(s) that is very noticeable at idle, and sometimes when shifting. I don't want to say backfire, because it's not a big pop, just a cough.
The bike is very underpowered, so much that I thought maybe a belt was off by a tooth...checked that last night & the belts are in correct position. The vert. cylinder's plug is fouled pretty bad & exhaust smells like gas. Horiz. cyl. plug looks almost perfect. This makes me think ignition timing is either weak or retarded on the vert. cylinder, since (I hope) both carbs would be adjusted fairly close to one another, and might explain the hiccupping thru the carbs.
Any suggestions? swap the coils to see if the fouling follows the coil? I don't have a compression tester, but can get one...how do you adjust ign. timing? or at least check it?
