2012 XCT. I replaced the clutch cable with the hydraulic unit. During normal acceleration everything is fine, but if I twist the throttle a bit harder I can tell it's slipping. Any tips on how this could be adjusted?
It shouldn't be slipping. I'm pushing really close to 120/120 with my upgrades and have no issues with the clutch slipping. I would make sure you have the system bled. There have been some that have bent the mounting bracket for theslave cylinder over some to make an adjustment. I wouldn't advise doing that until you have ruled out all other possible causes and confirmed that it is actually slipping.
First step would be to change fluid and bleed system depending on age. Also make sure pivot point on clutch lever is lubricated....it does make a difference! After that you can change oil and see if it helped. My 2011 Vision started slipping @ 18k miles, bone stock and Victory oil. My 2009 never gave me any issues with 40k miles, Mobil 1 oil and Lloyds bits @ 108hp/112ft.lbs.
