My bike is cutting out at mid to high rpm. Low hours, drd full system, jetted spot on, valves in spec, 06 cdi. I'm at the park right now and this is killing me. I hope its the tps so I can continue to ride today after I disconnect it. I bought the cdi off here and it could be bad. Any suggestions? Thanks in advance.

Tried the tps it didn't work. I don't have the 08 ecu to swap right now.

Well I traced it down to the charging coil. The spec is 720-1,080 ohms and Im getting an open line. So I need a magneto assembly which is $150. I'm gonna double check before I bite the bullet but I just wanted to update in case anyone else has a similar problem.
