I don't think you can weld cast aluminium!!

yeah, you can :wink:

Doh! Never thought of that! :idea:

According to here

it's the same part number(s) front and back, so Bob's your do-dah. :lol:

My bodge-fu is superior :)

on some years the rear cover has lug but with no hole

...but rob's knowledge fu is mightier still. Mine's like that, jogged my memory.

As stated, not load bearing. Epoxy, or better still JB Weld (special metal/heatproof epoxy base stuff) if you can't source another cover on the cheap.

Thanks guys for your suggestions. I'm going to go with the epoxy & black paint solution. If that fails I will swap the cam covers round, but not too keen on doing this as it involves taking the engine fully out.

Nah, it doesn't. Just wants the radiator shifting and the plug leads pulled. You can swap cams in the frame, never mind the covers. 3 bolts...

Yep. And that results in things like me shearing off one of my rear brake caliper retaining bolts and having the bike off the road for a week (and counting) whilst I wait on the replacement part. #-o :oops:

Sickeningly, I actually had a torque wrench with the right range to do it and actually know the correct torque setting. I was just rushing and trying to save myself 5 minutes. [-X Well, that backfired... :lol:

Still waiting for the bolts...

...on the plus side, I can now justify the 60-300NM torque wrench I've had my eye on for some time. 8)
