I was wondering if anyone could help me out? I have a 95 xcr600 that I put slp pipes on. I have installed 10MW weights in the clutch with the stock blue spring, the secondary is stock with the red spring in #2 hole and the 34 helix. My problem is that I have a huge bog if I pin it out of the hole, it will almost die I let off and it takes off. If I hold it it will spin up to 9500 and hold there. If I get into loose snow or powder it seems to slow down drastically, while on harder snow it will pull up to 100 or so. I would like to lower the rpms closer to 8500 because I just put the motor back together and I don't want to have to do it again to soon. I am planning to put a black slp spring in the secondary and a helix but i'm not sure which one, I was looking at a 42/32 or a 42/36/34. Not sure if this will help my problems or make them worse, any help would be appreciated.
