I am tuning in my sled with the stock arms and a roller secondary. At this point it comes out of the hole at about 10,100 and climes to about 10,700 or 10,800 at about 120 on the speedo. I want to bring the low end rpms to about 10,400 - 10,500 and leave the top end where it is. If I remove the first rivet in the arm or maybe the 1st and middle will it bring up my rpms that much?

How many miles on sled? Just let it break in and it comes right to life just like you want it. Take off the roller secondary and put back to stock. The roller will do nothing for performance. Been there, done that. Wasted allot of time and money. Mike Knapp#17

Mike have you ever tried the HC-X from Super Torquer? It is totally different than other roller secondaries. I have 500 hard miles on the sled so it is plent broken in. It runs pretty good already. Ran a ton of modded F-7s,rev 800s Srx and even 1 Mach z. Walked away from all of them except the Mach. At about 110 on the speedo he started to catch me but did not get by in about 1500'. Just want to bring the low end up a little.

For drag racing your sitting pretty good right now. If you want higher rpm,s grind off about 2 grams from the inner rivet.

Turk, So you think 10,100 running up to 10,800 is good for dragging? I have not tested this but I thought 10,400 running to 10,700 or 10,800 would be best. I am geared down a little with a 39 on the bottom and I have plugs and a ram air. I run a 1" track with the Ski-doo drivers.
