2010 M8 Clutching?????

[09snopro]

Riding around 7,000ft with the Drive: 68g weights yellow/white spring Driven: 36 degree helix orange spring. The problem is it is only pulling 7500 rpm. What are some areas I should start looking? Thanks

Hopefully RacinStation jumps on this thread. But as you drop grams the sled will increase RPM. When you increase grams it makes the motor pull harder so less RPM.

Are any of your clutch weights broke? Or cracked spider in the primary?

I think your just to heavy on the cam arms. Try 66gr

I'm down around 65 grams with some tip weight ground off on same sled and altitude.

I'd say your secondary is binding. When did you last check the bushing for wear. If it is not very close to spec you secondary can bind causing low RPM. I am now there and will be sending my secondary to Racinstation after the new year for rebuild Oh and I ride 5 to 8 k around the McCall area.

depending on miles I would check the secondary. around 2000 is where they seem to go bad. If the secondary is good, drop some cam weight.
