Getting ready to install a 43/47 helix in my 2011 xrs 600 etec shortie. I see it has a helix that kind of looks aftermark in it now. It says Q7 on it. Anyone know what this one might be?
I also plan on installing a 160/290 primary spring. Lots of people say it performs great on the 600 etec with a 120" track.
Thanks for your help. :face-icon-small-coo
