getting ready to start my restore,, Should have done it over winter but hey...
Not sure if it will matter when I start ordering parts.
But here's the engine/frame numbers.

4R4-007508 (Engine/Frame)
JYA4R400 4 BA007508
12/80

Title says 1981. NOt sure if those 2 years will matter in parts I order.
I'm assuming the 12/80 meaning the manufacture date.

Any info on the bike you can give me would be great.
 
Yep 81. When ordering most parts the years 80-82 sohc will be the closest to your bike. The 77-79 sohc bikes have a lot of the same parts but not all will work will work with yours. How about posting some pics of your bike. We like pics.

Here's the little beast. I pulled the front wheel. off to change the bearings. Need to do the shock oil, and change the tires this weekend.

I picked it up last year, I bought it for 500, ran rough, but found it was only running on 1 cylinder. Change of plugs, wires and boots got it firing on both cylinders.
