Have had no problem with a Rivera hooking up even when my engine was on kill before pulling it back. Check your side cover to make sure the weights are not touching the cover stopping full throw, also check to make sure it is adjusted proper. Something's not right here, that clutch is tough.

 

I would've thought a little more as well.. can you post a Dyno sheet?

 

Turns out I needed the "Gold" race spring . It will be back in the dyno Tuesday..

 

 

 

I had the silver only good for 115-120tq gold is good for 150+tq so that clutch should work well no matter what motor.

 

Dream Rides in Stockton CA. Just got done with my Dyno. Said it went 113hp 130tq. Sae. He also said I should have kept my fat cat on there but that thing hung down low. I pick it up tomorrow.!!

 

Very stout! Congrats and have fun

 

The 113 is a potent engine, should go thru the tire quickly with those numbers.

Was kinda confused about the gold spring and see why after your pick, I have the Variable Pro clutch, it won't slip unless I sell the other remaining kidney for a Procharger

 

Aahhh Ah yes that was next if the gold couldn't hack it
