does anybody know what year the 650 t-jet was made ,what is a running 650 and pipes worth,thanks

I think the t-jet 643's were produced in '72 and '73 only
as far a value? hard to say. More valuable to a collector who is putting it into show sled. Not too many are raced anymore
check out Blake Reeds snojet website: http://users.accesscomm.ca/rread/snojet.html

thanks for the info ..is this the same engine as the yamaha SR had?

 

[GP292Racer]

Same engines, but Sno-Jet was not given the oil injection

 

[montynormand]

I do not believe that the SR engines were oil injected, were they? look at the cylinder casting numbers and I can tell you exactly what you have

The 72 SR 643 had oil injection and tilted plugs in the heads. 73 SR 643 used pre-mix and had plugs straght up in the head.
