Rushed home from work last night...Borescope fired up and down the plug holes,Couldn't see anything obvious,couple of slight marks on the bore but certainly no gouges!!! Looks a lot better than my KTM crosser barrel.
Turned it over to check the whole barrel and all seems fine. Fancy wee mirror fitted to the borescope to check out the valves etc and it all looked fine too:thumbup
Changed all the plugs for the correct heat range and torqued them in cleaned plug caps and fired her up. Sounds ok.
Will need to take her for a run too see if everything is ok but i will wait for my seconhand cooling fan arriving just in case.
