mine did the samething and i thought i burnt up the clutch so i ordered another one and it still wont grab as hard.i also orderd the mip clutch and the spring they sent me was skinnier than the one i already had on it is there a difference in the size of the spring.thanx.
The lighter the spring the earlier it will engage. Also, I think the MIP shoes are lighter than stock, so the require a lighter spring to engage properly.
