hi i,ve got a predator 07...Great bike but got a big problem
my inlet valve clearances keep closing i keep putting in thinner shims and now its running out of space....

i raced it in an 8 hour endurance and adjusted them first after the race they had closed back up ... any ideas what it could be would really help me out cheers

have the valves redone and go with an aftermarket valve, as far as why
do you run on the limiter alot it will shorter the life of the valve. What shim are you on now?

if you run that machine wide open alot then it will cause that. Those stock valves are good, but i would go aftermarket. I had an 03 Preddy, and i put in an HPD 558 kit and there valves and springs, with there cams. I have never had a problem!! I could run that thing wide open all day, and it never gave me problems.

yeah its only the intake valves that will give you trouble for whatever reason.
