1967 yr1
« on: December 02, 2022, 06:01:02 PM »
this is a project i did a few years ago. it was a labor of love for the 2 stroke twin that started 40 some years ago as a 16 year old with a brother that left for collage. he left me with his rd350b that had bassani's and filter pods. so for the yr1 i modified a set of dg pipes, added filters, and jetted it. what a bike it was.

Here’s the ‘67 YR1 I brought back a few years ago with before and after pics. It now resides in NY state sold on eBay. I told the new owner about 2SW but I haven’t seen him here.

BTW, if anyone needs parts for the YR1-3, I still have a few.

Wow, nice work! What's the silver horizontal bar in front of the cylinder heads? Hard to tell in the photo.

Mark is correct as I found NOS period correct twisted chrome highway bars that I just had to put on this bike. I probably only put 100 miles on it and could not get the front drum brake’s stopping power to my liking. It also had a front end shimmy that I chased for a long time which turned out to be a warped front axle. I had another NOS axle and shipped it to the new owner. RB Designs rebuilt the crank and I found a pair of 5 port ‘69 R3 cylinders that we used. Thanks for the compliment and you just can’t keep ‘em all!

they were definitely ahead of their time.
i don't think i could use the highway pegs even in my younger years.
