hey guys. I have a clutching question for you. My dad has a '98 v-max xtc 600 and we just recently got done doing some mods to it. I need some input on fine tuning this thing in.....clutchig wise that is. We got all these parts from Hauck powersports. Here's what we added: reed spacers, carbon fiber reed petals, thin head gasket, hauck blue primary spring, hauck green secondary spring @ 80deg, 6ms7 helix (maximum performance----I think a 51/47), stock rollers, hauck "x" adjustable weights, w/4.6g inner--1g center--.8g tip. off the line it will pull to 8150-8200 and then climb to 8400-8500. This was the 3rd run and it did the same thing on the 2nd run w/weight as follows....3.3g inner--1g center--0g tip. With the added weight to the inner and tip, why the heck would the rpm's not go down? Where should I add weight now....on the tip correct? How much would I add to get it to run at 8100? Some guys were saying to clutch it to run @7800, but that seems a little low to me. 8000-8100 seems better. On my ski-doo 600ho rev, if I add like .5g on the tip, it will drop peak rpm's like 100-150 rpm. On this v-max there was no change. Does like 1g on the tip, drop the rpm's like 50-100 on a yammi? If I add more weight to the tip, could I add more inner weight, so it would help get the weight to swing out?

no one has any thoughts?

I recently bought a Hauck clutch kit myself. If I remember, the setup sheet says to add the provided weight in order to increase the RPMs (or change the spring position of the secondary helix). I can't confirm this because the setup sheet and sled is 300 miles away at my friend's cabin. I was also told from a respected tuner on this boards, to add weight until I hit the desired RPM (8100 in this case for my 96 VMAX XT with my particular mods). Could this be your problem or am I crossed in my thinking? Can anyone else confirm or deny this strategy?
sounds like you took weight out , you need to add weight to the tip,try 3 grams. rpms should be around 7800 unless you have it piped! go back to your first setup and add 3 grams to the tip....if to much (rpms to low) take a lil out till u get desired rpm!(7800). If not enough add more weight to the middle.

Thanks for answering my question, I had it backwards. The original poster did add weight but didn't see a drop (maybe more weight is needed as mentioned).
