got the bike back together today and rode it for the first time,and no surprises it worked first try! i was kindly amazed that it worked perfectly first shot,i used 5 tungsten balls and the soft spring on the perch adjuster and it grabs right off of 2000 rpm exactly where al said it would(thanx al)great engagement,perfect comes to mind! no slip just hook up and go.it definately was worth the money,i tried to stall it on some nasty hills behind the house and could not,got to the top and had nowhere to go,turning around was the hard part! it lost no compression braking and the only drawback i can see is you can't bumpstart anymore,oh well small price to pay! the install gap was a tight .030 so break in should put it right where it belongs(will check after one more ride) so far after an hours ride it has not changed any, and doing the 3rd gear brake test kills the rpm's so that is good,and have the proper play in the lever still so it might be good to go!(will check anyway)great product,i didn't believe at first but that changed quick! thanx to all the people who answered my ? all through the process, i'm glad you talked me into it..... if anyone is considering one go ahead and get it, well worth it.
