Black/Gold,
I'm curious about the bronze small end rod bushes. Did you add these? Why? Are you running a different piston/pin combination? I've seen these on Triumphs, but never on a Norton before. Inquiring minds want to know.

Well as for the small end bushes, I didnt add these this bike has been in my family for 20 or so years. When my dad picked it up around 75 the previous owner had no idea and he had put the pistons in around the wrong way and the isolastics were up the shit. My dad rebuilt the whole thing and then added new clutch plates. He took off quickly and snapped the mainshaft in the gearbox so from then till now the bike has been sitting in pieces.

RE: Bushes

I can't remeber why this was done but I think that someone may have reccomended it, not sure.

I don't know for sure but it seems a feasable explanation. What is your opinion?

Cheers

Black & Gold,
Seen the photo's and I am very impressed, it looks great and ready to get out on the road and ride. I'm rebuilding a 74 model in Sydney, but not so far advanced. Work stopped today, 44C inside the shed and more outside.

Cheers Richard

Congrats on a first class restoration.I am in the process of rebuilding a '73 Roadster[Oct 72 build] in tandem with my mate Richard who is rebuilding his 74 850. I was at first puzzled by the black cylinder barrells rather than silver, then my old eyes picked up the engine no 204###which I note is a combat motor and hence the correct black colour. Did you need to "superblend" the bottom end ? :)

well hear is the story my dad has owned it since 1975 when he rebuilt it in 76 after the previous owner had no idea so it was rebuilt then having the bottom end done and a reco head and such he later on replaced the clutch took her for a rip and snapped the main shaft in the G/B wich in turn ruind a few gears and a case he got a replacement case but was not machined right out of factory thats were i come in about 20 years later when i was doing an enginerring course at school and decided it was time for the old girl to be on the road again fixed the case tried to kick her over no luck it had been ceased up pulled it apart but left the bottom end as it was fine so that stayed as it was as it had only just been rebuilt before breaking the G/B got the cylinders resleeved back to original size and got new pistons and rings and new valves guides collars and collets and just added a few other things in between like the new paint new front shockers and gave her a polish so about the bearings im pretty sure that they are the roller type but not positive as i wasnt around when it was done as im only 16. so thats the story on the bike.
