Thanks for all the comments guys, I took this bike on an epic ride Sunday as part of our local DGR, it got lots of positive remarks and plenty of nods of the head, the bike handles some fairly heavy traffic and some nice open roads, marked each stop over with its oily calling card but otherwise behaved impeccably. Lots of people wanted me to leave the bike as it is and I understand that approach and I take on board the comments on not over restoring it, the original picture as I purchased it started with a bike that had not seen a lot of love recently, had a Honda tank and a gearbox that didn't function so if its about keeping these bikes on the road and working hopefully that box has been ticked. Next is to return some of its finish and dig a bit deeper with replacing any worn parts.
The bike is now fully stripped down and the jobs list includes new wheel bearings as a couple are a bit notchy & new front shoes. The gearbox now functions really well but leaks oil which needs a further look - does anyone have any recommendations for oil grade / type which may stay inside the box!! ? I am going to use this opportunity to also look at the engine and check its health and maybe look into gaining some further performance + painting the tank and other parts. Its been a great learning curve so far and I see lots of fun to come.
