Hi Richard 54
Yep raced n built just about every type n size of bike you can think of from super light 125 suzuki stinger in the 70s to my last one 3 years ago a 900 fire blade , went drag racing with a kh 750 kwaker 2 stroke tripel .
Not rode for 2 years now as balance not good but am hopeing to get a 1800 Harly abandond projecte and have use of an old air strip lol still got a 1100 v 4 honda cant bear to part with it , lol.
The old bikes are harder to ride but great fun , you need to be a better rider to get the most out of them but its worth it.
As for over hauling your bike why not start small with just a top end rebuild rebore piston grind valves eck eck eck,
or just a full service and tidy up n see how it gose from there im building 4x4 s at the moment it keeps my brain active and my boady moving lol
well thats all for now so live well n ride free Cc
