Took the ole girl out for a ride today and it felt like the chain in the primary is slipping when I get on it hard(loving that big bore kit). I checked the belt and i is tight. Can anyone give me something to look for.

 

You have a big bore, what size? Did you upgrade the clutch spring or add a VPC? If not, that's probably what's slipping.

 

Chains don't slip, they break, but the clutch certainly can slip.

 

Hey DUde , before you start tearing down try draining your primary oil an replace it with "0 viscosity" "100% silicone motor oil" . Drive around town , so you will have to shift a lot soaking the clutches about 10 miles or so. if the clutches are good this should work. just my thoughts . Duane 08 Blue Ultra #617849 Born 08-02-07
