Great Info
This man has a few video's on you tube. I talked to him Friday for almost an hour. He has the Doo clutching and balancing figured out. His test set-ups accurately measure run-out and vibration correctly. He balances all rotating engine components on the sled. Both clutches, flywheel, crank shaft, ect. He has worked on many Doo's and can get them to sit and idle without a windshield shaking.
He's in Utah, which for me is bad. I'll have to ship my motor out, I'm trying to figure out the cheapest way. A balanced engine will last thousands of miles, unlike the crap Doo sends out. I'm at 3K miles and my crank seals are shot and my sled shakes like a damn Fusion.
Give him a call. He's very nice and has the ability and equipment to get these machines fixed correctly. I'm waiting on some extra cash and my engine is heading his way.
