I have the holeshot in mine. It does make a difference when you hammer it off the line- after that there is no difference, no change under normal riding conditions. All in all a good mod for a little boost out of the hole- but you will never feel it unless at wide open throttle. I would buy it again. I have epi black spring as well. Grips the belt much better and makes low gear much lower with way better engine braking in high and low. I would also buy it again. I think that is a good indicator if it is worth it or not- if you would buy it again after you had it for a while. Thanks.

 

Cattman, I'm glad you said that. I like my low gear how it is. I will have to check in to the Holeshot. Thanks for the info!

 

You guys with the artic cat 650's..... get the black spring asap!! Makes the belt tighter. Tighter belt = longer belt life and less slipping. Also i just put in a nabor mod. Similar to the dg holeshot and reds650 mod. All i can say is make sure you got a firm grip!!!!![img]i/expressions/face-icon-small-wink.gif[/img] I have a 2500 lb. warn and a custom box on the front of mine, i could get her to wheelie with some effort. But now all i have to do is try and hang on. LOL

 

WHERE CAN i GO ONLINE TO FIND MORE INFO ON ALL THESE MODS i,ll be installing my outlaws soon just arrived new set for the front so i,ll need that black spring for sure

 

4x4 races are exciting, WTF
