what year is this motor

is this an 83 or 84 vf750 f motor number Ro15E-2005090

 

how do i find out what year this is. was ther a diffrence between 83 and 84

 

Most likley an 83. My 83 is RC15E2000875. Yours should be RC not Ro. ??

 

your right it is rc but what number tells the year, and whats the diffrence in

 

Try this VIN decoder, it should break down the code to tell you the year, engine, plant of assembly etc.

 

It's a 1983 VF750F engine. The engine serial numbers 2000022 to 2008111 are for that year. I hope that helps!
