Two of the exhaust head clamps on my 81 GS650E were cracked and broke when torqued.
Tried to use different high heat epoxies and puttys along with steel dowels inserted, but all attempts eventually failed.
Finally took the pipes to a welder, but the material (cast aluminum/zinc?) doesnt hold up to welding.
Looks like the only real option is to replace the clamps which requires cutting the welds on and removing the flange piece, then installing a replacement clamp.
Problem is that the clamps are integrated exhaust parts and not individually available.
Several GS models in the 79-82 year range do have replaceable clamps that are available, but I'm not sure if any of these would fit on my bike.
My dimensions are approximately as follows:
Pipe diameter: 35mm
Pipe Flange diameter: 45mm
Clamp bolts distance: 55mm
I would guess that the clamp inside diameter would need to be around 37-40 mm
One type available seems to be combatible with the 850 and several other models.
Any help on this would be much appreciated.
