Clutching help needed

[01sxr700]

Last year I put a 144"x1.5" crossover track in my sxr700 and had clutching problems. So this year I changed the clutching to MM specs. Have stock MM helix 43 deg, weights 8cr, rivets 10.3al/10.3al, 14.5mm rollers and springs (ywy primary, green secondary). The only thing slightly different is the gearing. The MM setup is 21/40 and I have 21/39. My problem is over reving,when I punch it, it goes to 9400rpm then back to 9200 and holds there. Do I just need to replace tip weights with heavier and if so which ones. Engagement is at approx 4700 which is stock for the MM. Any help would be appreciated.

Thanks

what do you have secondary set at for preload? probably going to need to run 4.5g rivets both holes, or 3.6g inner and 4.5g tip.

Secondary set at 70 as per MM settings

i guess try heavier rivets.
