Hi all,
I have searched for any info on this site with no luck. I have a 1979 CB750F SS which i bought for parts for my 1980 model. The donor bike is in pretty poor condition as it has been stored in a damp location, although it does run ok. I want to get the RH exhaust pair off to put on my 1980 which is holed due to battery leakage but I am having trouble getting the finned exhaust clamps off the studs as they are 'welded' by corrosion. I have tried penetrating fluid for a couple of days and I have also tried heating the alloy clamps but still no luck.
Does anyone have any tips to try to remove these clamps?

I only joined the forum recently but enjoy reading all the info contained. I only wish that we had as many sources for parts here as you have in theUSA. Parts in US are relatively cheap but mailing costs are high, especially to Europe.
