My guess is its dropped a lifter. Needle bearing has failed, dropped its guts thru the cam gear drive.
Just component failure, it happens, and not attributed to servicing or riding styles, good luck with your repairs hope your up and running soon.
Any reason you wouldnt drop in a cam? You'd lose nothing, and gain a bit without compromising anything.
Yes, but any ideas on what would cause this to happen?
Definitely drop in a bolt in cam and fit full compliment cam bearings while you are in there
Stock lifters and the stock cam bearing are just not that good a quality mate. You're rolling the dice running them mush past 40 K klm's IMHO.
That bearing was the first thing I replaced on my old Evo.
Have a look at this address below and pick what would be best for your style of riding. Lean towards low to midrange power rather than hi end I would think.
just thought I would add, if it was me and was in your budget. I would change valve springs to beehive springs, as do not need as much valves seat pressure. so will take more wear and tear off the valve train.
I’ll chat with mechanic today to see where I’m at with the cash, it adds up quick!
