Hi Guys, I hope I am not intruding into this thread, and my 1985 Honda NV400MK2 is also considered a classic. I need some recommendation on a good workshop/mechanic who can properly do up the bike. It needs some carbureter tuning, valve gap setting, clutch plate change.....etc. Those motor tiam owner/mechanic who I know are familiar with this bike, are not interested to touch my bike, for reason that I believe is too "slow" money making business for them. I understand old bikes require Leaded petrol, for the engine to work properly. I was once advised to use the petrol additive
