I've been a member on TY now for quite a few years and have noticed the huge amount of clutching threads. Just my .02, but clutch kits are a complete waste of money if you have no idea how to tune your clutches.

Do you know how different primary spring rates affect your clutching?
Do you know how your primary spring and weights directly affect each other?
Do you know what the secondary spring is suppose to accomplish?
Do you know how RPM is affected when moving screws, or rivets throughout the weight?
Do you know what the helix does?

Just some very basic questions that if you know, could greatly help you dial in your clutching. I would suggest anyone interested in clutching pick up a copy of Olav Aaens clutching book. http://aaenperformance.com/Handbooks.asp It's a pretty technical book, but if you read it a couple times it will start to make sense. Once you understand the basics of clutching, tuning the sled will become a lot of fun.

One of the best things I ever did was dedicate a few rides to clutching only. I brought different weights, primary springs, and secondary springs with me. I made one change at a time and took note of how it affected the clutching. By doing this, I got a much better understanding and was really able to dial in the sled well.

I guess to sum it up, I think you're way better off buying a $30 book until you know how your clutches work. I've been there and being clueless sucks.

cutler performance also has a 100 page book that is fairly easy to understand. When I got into backyard racing in the late 90's skidoo had a annual race handbook that covered clutching and everything related to race setups . You can learn alot from reading but hands on is the best experience you can get. I used to test on the track come home and compare notes to what was written in race book. Sometimes it worked out sometimes not. I agree with Nikolai need to have a basic concept of why you are changing parts.
