I have a 99 and about year ago it developed a miss when the rpm gets to 2800 and quits at 3500. It does this most of the time but not all. When I got the bike it already had the full Ti. Achropvic exhaust, the breather was modified and it had the Power Camander on it. It allways ran great exect for a lean stumble at the lower RPM. I lived with the stumble for a year. But then it developed this miss. The miss got alot worse sometimes feeling like it was dropping a couple of cylinders over all Low RPM. I took it into a local shop and he said one of the coils went bad and he replaced it with a used one. At that time I had him tune on the programmer a little bit to help the stumble out which he did make it a little better. A few months after riding it four or five times the miss started coming back. I wanted to take it back to the shop to get the miss fixed and have him put it on the dyno to a full fuel map done on the Power Camander. I wanted to change all the coils so I bought four used coils off of Ebay. I took the bike over to the shop he changed the coils for me and put it on the dyno for tuning he said he was able to get fuel map done and it made real good power 168hp but the freaken miss is still there at the same RPM. The lean stumble is fixed. But the miss. It does it almost every time it goes through that RPM range. The shop guy said he was baffled is not sure what it could be and if he is baffled,I sure am. I am sure hoping someone on here could help me out so I don't have to spend a bunch of money trying to chase the problem down. Sorry for being so long winded, I just want to give all the facts to get the best help.
