All of this sounds good. I'd add a new performance CDI box also. It gives a better advance on timing plus it raises the RPM limiter. Gives you more to work with. I also added an exhaust from a mx bike for better performance. I'm a "crawler" also. Looking for even more low end!

Would love to find GURU style bumpers! By the way, I'm also a graduate of AMI with over 20 years of motorcycle mechanical experiance. New to quads, but the same basic engines. 2 stroke or 4 stroke!
