I was in the process of valve checks for my 2006 ABS ST1300 tonight....
I noted the dealer that serviced the bike last from previous owner (yes, name and shame! Ferntree Gully, Vic. Jeffrey Honda, no longer in buisness....
) has worn of the soft walls of the 10 mm Alan / Hex inspection / crank cap on the front engine crankcase cover.

I also note he has mangled the o-ring of the cap which is visibly pinched and making a nice little mess....
The top (valve T1 T2) inspection cap was also mangled by the same heavy handed idiot, but I got it off eventually.
I have removed the front wheel and guard for better access.
I have tried the following to no avail:
slightly lager hex 11 + 12 mm, the end of a 1/4 inch socket extension and Torx driver
it's locked on tight and the 0-ring is likely binding the alloy cap to the cover.
I cant weld, tig, mig due to risk of creating further engine problems without removing case cover, I really dont want to remove the cranckase cover, oil etc...
I know a large grabbit / ezy-out will do the job, but involves drilling and thus, removal of the cranckase cover to avoid metal shards dropping into the sump...
I will try to use a hammer / persuader tomorrow to "set" a 1/4 inch extension bar, and hope to break the seal that has been created.... but would appreciate any advice from our fitter/ turner lathesmith professionals, if possible. I will order the damaged caps and o-rings tomorrow...
thanks
