alright, let me first say that i like the clutch and my problem is that i dont have the lever override. i was riding this huge, steep and rocky hillclimb. my trusty auto-clutch 426 has never let me down, but this hill was different. my bike pulled hard at the bottom of the hill, but as i got further up the hill the RPM would keep dropping... to the point where i would stop and be unable to start uphill again. i kept trying it, raised the stall speed, but nothing worked. it climbs everything but that hill. just a heads-up. if your a perspective auto-clutch buyer and think it will make your bike a great hillclimber, be prepared to spend the extra $100 on the override lever.
