Hi guys, I have 1968 Sportster that I think needs new clutch friction plates.
The stock replacment plates are $36.
The Kevlar ones are $69.
The Carbon Fiber plates are $89

I assume that Carbon Fiber are best because of the way that it disapates heat.
But is it worth the extra cost?

My bike is 900cc with a mild cam, pipes, and bigger carb so I am not making a great amount of horse power.

 

I use Energy One clutches (http://www.energyoneclutches.com/sport70.htm). They make the plates for Rivera's racing clutch kits. Best on the market and at a lower price than from other sources. Carbon fiber isn't worth the extra $$ unless it's a race bike.

Also, I use stock clutches on my '76 XLCH race bike, and have never had a problem with them. It's your money and your choice. Either one will work as well as the other.

 

Thanks for the info. I believe that because my bike is mostly stock and will not be raced that stock replacement clutches will work.

I have also heard that running only a small amount of oil (like 6oz) in the primary will prevent oil from getting on the clutches. Because as I understand keeping the dry clutch setup dry is almost impossible with the primary filled. Is this a good idea or not?

Thanks
Mark

 

ALWAYS run what the clutch plate manufacturer recommends for oil weight and amount. Energy One recommends using the stock level and non-synthetic oil with their clutches. If it's a dry clutch, then do what the factory service manual recommends. The Energy One clutch for your bike is a wet clutch, so use the proper amount of oil or you'll burn up the clutch and destroy the primary chain. The oil doesn't just lubricate, it also cools everything.
