Last year my FI light was coming on. I pulled the air box and found a large leaf in there. Removed leaf and replaced air filter with KN filter. No light the rest of the season. This year after a few rides, the light is coming back on. I took it to the shop to get coded. They call and tell me it is give ALL of the following codes: Map Sensor TP Sensor 1AT Sensor 1-4 Injector What the heck??? So, this was a 1 hour charge at $75 and hour. They call and tell me it will be an additional 1-5 hours just to diagnose and then the additional charges for fixing it. The bike is a 98 with 11,500 miles. Any advice would be appreciated. -d p.s. the bike seems to run fine light or no light, i don't see a difference. bike does have a 2bros full system that was installed by the dealer at about 8k miles.
