clutch balancing

[big tom]

So just coming off a doo rs860 mod with a race supposedly balanced light weight primary. I just watched a youtube vid at Patrick custom carbon as he took 3.8 grams off the fixed slevee and almost 14 grams off the outer with assembly of the same clutch. So how balanced are the Polaris primary's ?. Are they in need of balancing?. I notice in the 200 miles I put on in I have some pretty good ski shake at a idle. I don't want crank problems down the road as there not cheap when they come apart..

The P85's are usually pretty good from factory and not as bad as the tra

But, I would get the primary balanced anyways
