Changing bottom end?

[IanC]

I need to replace the cam-chain tensioner rail (plastic) on the LHS top, as it's broken. I'm told the only way to do this is to split the crankcases, as it pivots on a pin sandwiched between them.

Apparently a better option is to put in a new bottom-end. Motorworks have a few @ £475 a shot, but obviously the major deal is fitting it in the bike - changing the cylinders/heads being comparitively minor in comparison.

Any recommendations of an independent who could do this? I've established it's just not worth doing on a 77,000 mile bike at BMW labour rates I don't need it doing 'yesterday'. It's a 2006 GSA.

Dunno if this is any use to you - it's the 1150 but I guess it's similar:

Thanks Chris, that may be very useful!

I wonder if anyone's done this on a 1200? Steptoe???

To confirm, it's the top LH blade that's gone.

I've never done it on a 1200.

But see no reason why it can't be repaired in the same way as the 1100/1150..

I'm going to collect the bike from dealer and give it a try - nowt to lose really as the only other viable option is to sell the bike for breaking

I'll report back.
