Not really a frame question

I'm trying to figure out what 650 i have,The frame question is the neck is stamped the numbers 447-911334, i've looked here and there,they do'nt match anything i've found, come close.It's a 1980 as far as the papers,but as i said the numbers do'nt match. Help?

thats a 1977 number , I have one similar to that number., possibly early 1978 it could be at latest , but I don't think so , I think its '77

So what your saying is the frame is from 77,but built in 80?How about the motor? I't stamped 4T6-000681?

a little search on google for your motor number and I can conclude that its a "special" , the motor is anyway, so its a '78 or up , probably is the 1980 motor it says on the title, but its on a '77 frame, if you have to have the numbers match like I had to in my state here in Mass. , frame needs to match the title, you will have to do a little custom work, get yourself a set of 1/4 inch metal number punches , I got mine on ebay, then I ground down the numbers on the neck to flush metal again , then stamped with the 1/4 inch set the same as the engine, gave it a little black spray paint again and bingo!

Thanks xsfun
I can go with the fact that it's a 80 special,no need to punch #'s they match as far as the ownership goes.

most welcome, someone somewhere along the line made 1 bike out of 2 bikes, you will have to determine what parts are when you go to replace anything, cause you have a '80 motor on a '77 frame, are the forks , rotors, calipers, brakes etc..etc... from the '77? cause they are different from '77 to '80 for sure.

I'll have to run with part numbers there.

Bought it new in 78 ... still have it ... stamped on steering column ... 447-9030xx ... MFG 04/78
Its a 78 Special ... chew on that Smile

mine is also stamped 447-9xxxxxx and its a '77 , so it appears they used those numbers thru early '78 as we thought earlier ,same frame, but his motor is different number.
