Hi all.. I'm based in South East Queensland. Motorcycle tragic.. Recently acquired a 1966 YDS3. Woo hoo...
Wow , that's nice , well done. There is a service manual in the resources section if you weren't aware of it. Yamaha YDS3 250 Service Manual | 2FIFTYCC.COM - Home of the Quarter Litre
Welcome. That is nice. Remember NOT to sit at lights etc with the clutch pulled in as no drive to oil pump. And if you are looking for the 7mm hose from tank to carbs, then go to mower shop and get the black hose from a B & S motor. I restored a YDS5 a while ago.
