1969 Yamaha R3 'Grand Prix' 350cc twin
My first riding experiences were in the mid 1960s on a BSA 650cc Lightning that was owned by a friend.
He taught me the essentials of riding and the bass-ackward controls used on the Brit bikes of the day.
After I got out of the Army in 1968 I borrowed a Honda 305cc from a friend and proceeded to thrash it thoroughly.
I rode that little Honda 305 everywhere for several months.
Finally, I decided to get my own bike, besides John took his Honda back, and I bought a new Riverside (Binelli) 350cc single from Montgomery Wards.
It was the most miserable bike I could imagine.
I took it back and got a complete refund within a month.
A classmate from high school let me ride his Yamaha 180cc twin.
I liked it enough to go to the local dealer and buy a new 1969 green Yamaha R3 350cc twin.
It was scary fast and handled better that most of its contemporaries.
The 2-stroke design was easy to take apart.
I spent hours tearing it down and tweaking the engine and chassis.
I ported and polished the intake and exhaust ports and experimented with the timing.
I ended up with a bike that did the quarter mile in 14.0 seconds flat with a terminal speed of ~100mph at the local drag strip.
A nasty spill on it in 1970 resulted in a big dent in the tank.
I decided to paint the entire bike black after I fixed the tank.
Sadly, I had to sell it to get the money for my new 1972 Yamaha 650cc XS2.
Here is a few pics of my old 350cc twin.
The prints are dated Feb 1971, but the film was probably in the camera for quite a while.
