does it come with the matching rocker cover?and where are you located?
Cheers
-
No sorry, it doesn't. Im located in Brunswick Melbourne.
-
unfortunately Curtis its worthless as the cam tunnel is line bored with the rocker cover and both are stamped with the same number,if you use unmatched items the cam shaft bearings can sieze.
-
ive got a cover that i brought for the rocker arms if that helps that im prepared to sell 147.pm me for details
-
if thats the case im sure a light hone would sort that out or put a coat of 3 bond on both gasket surfaces
-
thanks for the offer Matt but I don,t do things like that.
-
ive got complete heads as well but i only sell the small fin/inlet valve heads
-
Interesting, I do understand its line borred, Im running a SR head with the XT cover and had no issues yet?? I guess time will tell :o

I've had the tt500s for 25 years
And Never had a cam bearing seize yet . would be a lot out there with diffrent non matching covers ,
Like some of mine . Can't see why it would seize .
I had dramas with non bearing cam heads where the covers and heads were not matched and when they were tighten down the cam would not spin , because of diffrent clearance .

I guess you could get away with non matching parts most of the time but I have seen one non matching pair that was that far out that the cam would not spin because of bearing crush, Yamaha felt it necessary to number stamp matching head and rocker covers for a good reason,the same reason they stamp the cases.

plasty gauge is a good tool, back in the good old days with no money, a mortgage etc, cam rattling its head off, on the old Honda SL125 everyday to work ride,
surface ground the rocker cover down, figure 8's on wet and dry, plasty gauge check, rub some more, she's good to go, a new cam chain, Aviation sealant, the old SL ran for years, with only advance retard rattle in the points cover.
oh yer ended up cracking the piston in half whilst monoing in 2nd gear :o loss of power, smoke out the back, rode it home, wacked a piston in it and was happy except for end float in the crank shaft :-X
