Long time bike (2stroke) nut, currently in the process of building a air cooled RD with my dad.
He is actively involved in the vintage motor scene (building/riding old Nortons) n about 8 years ago he dragged me along to a classic race meet at Sydney Motorsport Park. I was bitten hard by the RD race bike bug n so the search was on for a suitable donor race bike.
Through the old boys network of mates in the vintage club we found a bloke that raced a 1974 RD350 in the 70's. The call was made n he was happy to sell

It was a true barn fined.....as we had to drag it out of a old overgrown weed covered chook shed. But it was worth it as the bike a little busted up, mostly complete, had been fitted with genuine TR3 barrels, heads, pistons, 36mm carbs n big pipes. A genuine kit supplied to racers in the 70's by Yamaha to get ur street going RD into race form. This was all well before smart phones but i do believe i have some pics as she was when we got her home. I will endeavour to find them.
So skip a few (8ish) years n the bike has sat idle while life happend e.g. traveling, house, marriage, kids.....but the time has come to finally get it built.
Plans have changed a little as we have picked up a few spare engines n a second frame. Most recently i have bought some 400 barrels/heads out of Tazy n sourced a 1975ish 400 bottom end out of Sydney, they should arrive any day now. It will be registered n we will build the 400 as a street motor n the 350 (with TR3 heads) as a race motor hopefully with a close ratio box. This way i can simple swap over engines when we go racing n stay within the period race rules.
Anyway, to much rambling here are some picks of her through the build n as it stands now.
