Wonder what year would be the best donor to put the Yammy 500 in?
Here is a picture of my 1978 390 AMX frame fitted with a SR500 engine. Front forks are YZ465. I built this in 1981 after the auto tranny let me down in the 4-day that year. It was campaigned in MX and enduros for a few years with the 500 engine.
Don't despair Husky lovers, the AMX engine was refitted a few year back and the bike get the occasional outing. I have a 1978 CR frame in the shed that I will one day fit a 500 engine into, I just need a bit of time and money.
