Hi Hogweed1963

and welcome to the site:smile

Some how i feel that tdrifter wont be hanging on watching this site for a reply after 3 years?i maybe wrong,but don't think so.

Must say though i do like the colour of your bike,its that paint that changes as you look at it at different angles,very nice.

when the throttle is closed and the bike is slowing down (overrun) is due to an air leak into the exhaust system.

Chameleon paint is the stuff, Oh wearer of budgie smugglers, and sodding expensive it is too.
