Years ago cams were case hardened, so once worn through the much softer steel would then wear out rapidly..
I have no idea if modern cams are the same though..

Well i had a ride out and engine sounded very rattly??
Did the valve clearances the next day and one of the screws needed 2.5 turns to get back into spec?? Very odd that they should suddenly be out..
Went out for a ride and within 10-15 minutes its rattling again..
Me thinks rocker arms/cam are worn through?
5500 miles on the clock !:steamed:

What happens is your quad stops !!
The clearances get more and more each mile until the valves are hardly opening, strangling the engine...
By what i experienced i would say 10 miles max from when its just down to soft steel.
Revs need to be kept high as mine got to the point where it was threatning to stall any lower than 2500 rpm.. chances of it restarting ??

Just pick on a part where there is an edge to gently tap it !
The gasket will make it stick down and its on location pins so needs a little persuasion to break the seal, then it comes off easy ..
It is only a cover so unlikely to bend something..
