I am using the standard clutching for the prox everyone else is using. It works well. I am turning about 8200 on a calibrated tach(thanks nickels) on flat panned trails.

It is alittle bit over reving....correct???? but in the loose, ungroomed, deep snow I should be fine, correct?

I don't want to buy a set of 66's if I don't have to.

Thanks guys.

Are you running 10-64? most stock piped 700 will not pull 10-66 weights unless its really cold and hard pack. your turning about 150 rpm to fast , it would pull harder if you get a lighter finish on the primary spring...... all the 700's I have looked at run 10-62 stock , adding 2* of finish angle to the helix would pull it down some also.

if you are running 8200 you are hurting your performance unless you've got twins that move the power band up... the bigbore ves motors do not over-rev well... you should be shooting for about 7900rpm on a stock ported motor with a single pipe...

See what it does in the deep snow, if it revs ok, try just changing the primary spring to an almond/gold. Are you sure the secondary is not slipping a bit? If you have the black secondary spring, try it and see what it does.
