Well after a week of applying penetrating oil, that the exhaust off, sheared another stud with literally no force, they are badly rotten and have zero strength left.
So net result have 3 sheared exhaust studs if looking at the bike front from left to right on the inner or no.2 cylinder both were snapped when i bought it going by the black marks on the down pipes had been this way for a bit and the flange was rattling down at the bottom of the down pipes. no.3 cylinder inner most stud sheared.
Sods law the easy to access 1 and 4 cylinder came off, studs looks rough 1 has been replaced looks new compared to the rest.
Access is not great, is there mileage in draining the coolant and removing the radiator?
on no.2 the access is really poor due what looks like an oil scavenge pip that runs form the sump to the head, obviously I would need to drain the oil to do this.
Question I am asking is will this give any better access as the frame looks to be in the way also?
Am I kidding myself on or is this an engine out job?
The studs sheared flush with the flanges so have just about 2 nuts depth left sticking out, but if they are that soft I imagine they will just shear flush with block if tried.
I don't have a welder at home to try welding a nut on and spin them off
reading this forum seems some have had a real nightmare with this?
Open to all suggestions or experience on this
thanks
