2008 Road king
Replaced stock comp at 14,500, now at 16,500 and still working like new. Much improvement in low rpm smoothness, and NO starter clunk ever. I filed out the primary and that was time consuming, over an hour just for that. I have the serivce manual and couldn't tell for sure if removing the inner primary opens the crank case, if so, timing this job with an oil change would work well. Guess that would require the inner primary to engine gasket also.
Some people claimed the transmission didn't clank as loudly after the change, but mine seems just as noisy, especially when going into first just after engine start. I had the starter BANG from day one but didn't know what it was until I read about the SE Comp. here. What a wonderful improvement. Making that much noise on every start can't be good for the involved parts.
Got my comp. and gasket from Zanottis, about $250 for parts and shipping. I'm glad it was no more expensive, but well worth both the price and effort. I also believe the manufacturer should include this item as standard on all the 96 ci engines.
Some folks had reported their dealer changed to the SE Comp. under warranty for just the price difference of the old vs the new piece. I took mine in and was told the "box of rocks" noise and starter bang were normal. Perhaps that's true, but it is all fixed now. I can't accept that any mechanical noise that can be heard above the exhaust, wind and road noise is "normal". Glad I did it, and recommend to anyone else considering it.
