I would not raise limiter to 12.200, its set at 11,700 the stock Gen2 tach is off by 1000 rpm, so I would shift it 12,400 on the tach. The Gen2 clutch is a waste for a landspeed bike, it's made for dragracing, you'll have trouble trying to use the clutch like it's made too with tall gearing. You pin the throttle and throw the lever otherwise it's not being used. You can't leave on a starting line of a runway like it's a drag strip. It's not prepared for traction. You'll spin or wheelie up, you gradually feed it what it needs as you learn how to progress the throttle in 1st. Here is our Production bike running 220 at Loring.
