Progress Update :
Now have 8 shiny new exhaust studs fitted, not pretty but all lines up and clamps the header fine.
Had to throw the header pipes and old end can on to do an oil change and dropped the coolant as well, thought I had over filled but checking the next day was spot on the middle.
Both the oil and coolant were jet black, had the radiator off so flushed all the crap put of that refitted and put the garden hose in the inlet and flushed it through a few times until it ran clear refilled with new coolant all seems fine
Oil I might redo once I have got the engine ran a few more hours as the sight glass while not black is darker than when i filled it already, must be collecting all the crap gathered in it over the years.
I painted all the areas behind the radiator, and the fairing is still off touched up the surface rust where i seen any, repainted the rusty rad guard, shoved some Redex fuel cleaner in the tank, had a look, no sign of rust or anything nasty.
Going to refit the headers properly now i know they fit ok, I have new copper crush washer/ gaskets that came with the stud kit.
The previous owner had issues with the headers blowing at the seal to the block he said the nuts kept coming loose and he kept tightening until he sheared the studs and necked the others then he sold it !
Given the history do I just refit with the copper or go belt n braces and use exhaust paste as well? or bed the copper gaskets in coppaslip?
I rather not have to take the headers off again, I think part of the issue was the rear support under the centre of the bike was not fitted so all the weight was between the end can and the headers. The headers are slightly out so will make up a spacer to bolt it into the rubber mount on the frame bringing it slightly closer without stressing the joints on the head.
Was considering getting some additional stainless nuts to act as lock nuts and cover some of the exposed thread.
I have stainless link pipe and option of cans to refit.
Got the engine running, it went fairly easy, rough as tho! got a lot better but still a bit lumpy at idle and might be a back fire when coming off a rev, hard to tell as the headers are leaking and throwing off all kinda sounds and heat.
Got much better when warm seems to rev quick enough idle almost settles small fluctuation.
Not over worried just now as still have to do the air filter and worth giving the carbs a good blast with brake cleaner when i have the airbox lid off? going by rest of the bike expect the air filter to be manky. Still to change the plugs as well and check the HT leads but facts it fired easy and revs makes me think its got an ok sprk?
Am I fooling myself or a bike that not run for 8 months going to need the carbs off and cleaned? plus no guarantee they were good when I bought it as clear little or no care had been taken with it.
Chain has rusted up as well will need to look at that when i have time
