I just bought my first new Prairie 650 thanks to all I have read here from you guys. This machine is a blast. Again from listening to all of you I ordered a new air filter, dynojet kit and Diamond G snorkel. I was thinking of the black clutch spring but had a few questions first. Is it hard to install or do I need any special tools to do it. I am pretty mechanical but I have never worked on ATV's before. I did just order a shop manual also. Lastly the guy at Erland Performance said if I wanted even more out of it I could get the primary spring as well, but I havent heard anyone here talking about that one. Does anyone have any info on it as to why it is or isnt used ? Thanks in advance, John

 

This thread probably tells you all that.
