Hi
A kind thank you to those who answered my question on the yellowing of my downpipes I have no idea if the exhausts downpipes are aftermarket versions as Muttley 🐕 has unfortunately had so many owners before me 20+ so its difficult to know what's been done before,
I decided to renewed the wiring loom over the winter and I might have found one of the running issues was 1 of the spade connector on the charging system (R/W wire) was not long enough so dismantled part of the old loom and refitted a original spade connector then put a volt meter across the battery with the bike running and as I increased the RPM so the voltage when up which is what it should do so hopefully that's sorted that issue
Think possibly the other reason might have been the oil was just on minimum line thought I only checked it 100 miles ago and it was further up the "within the fill range" should have topped it up then,
what a "PLONKER " Hopefully its not done any lasting damage to the engine and gearbox / clutch
So now I check the oil level every few weeks Lesson Learnt !!!!!!
Thanks once again to all those who have help me with Muttley
