RPM clock doing weird things

Well I attempted to open it all up the the Alan bolts are seized solid... Covered them in wd40 but no joy. Even a knock with a hammer wouldn't budge them.
Decided to leave it over night and see if the wd40 penetrates. The cables were well out of alignment so at the very least the fault shouldn't come back. Cheers all.

wd40 is not a penetrating fluid,you need a proper penetrating fluid like plusgas or similar,and get some heat on the bolt,when you reassemble the exup fit some stainless bolts,i got mine off ebay in the correct lengths
