Ran my clocked jammin yesterday for the first time at the Nitro Pit. I did not have a chance to play with clutch set up so I just ran it with the M2C 4 shoe all aluminum with 4 1.0 springs. Running it rich cause it's still new I could not get ample run times with the 086 pipe so I was forced to race tune that puppy. The power was insane and my buggy was doing wheelies all over the track! The engine ran flawless all night and was hands down the fastest thing out there. It needs a weighted flywheel and a 6MM venturie as well as dialing out some throttle and it will be perfect! Not as smooth as the JL but an awesome engine for sure.
