Go Kart/Mini Bike Clutch 5/8 Bore #35 Chain 11 Tooth

works great .

Easy installation works great

So far so good easy install took about twenty minutes and everything works as described

It worked but nothing crazy.

I have a 212, it is jetted, has a staged header exhaust, 308 cam, 8 degree timing advance, no governor, billet flywheel, 22lb valve springs, chromoly rods, and .009 head gasket. also has Pulstar spark plug and high drag magneeto. Far from stock. This clutch stood up to about 40-50 hours of punishment before the metal housing cracked. I have bought 2 other clutches of different brands since then and one of them also cracked in the same spot and the other is awaiting the same fate. It seems that regardless of brand, this is a bad design. I have a buddy that has a similar setup and a clutch which only has 2 shoes instead of 3 and he hasnt had the same issue. His is about to go out from worn shoes, not structural failure. I would recommend that if you have aftermarket parts. They sell them on BMI karts for 60-100. These make your motor die when they go out, youll know. The cluch completely seizes. The triangular shape on the back kind of loses a fin. With his the clutch has started to lag and make noises. It has seen about 130-150 hours.

Replaced the oem monster moto 80 with this a few months ago and it works great.

Improvement from stock

Noisy and slipped

Had good luck with 3/4 shaft clutches but this 5/8 one is a problem. I think the spring holding the shoes in is weak or poor quality.
