1980 GS850 engine --> in a 1982 frame and drive train no

[petermatra]

Ok I got this 1980 GL engine that looks good. She slid into my 1982 frame well. I HAVE ONE PROBLEM THOUGH

The final drive shaft mates with the engine, but the screw holes do not line up correctly. I tried to work the screws in FOREVER. the holes only seem to be off just a quarter of an inch or so.

Am I in trouble? Whats going on?

Years?

Are the drives diff. from '80 to '82??

[petermatra]

shafts 1980 and 1982

I thought all of that was the same and standard for the 80-82

I just compared parts numbers on BikeBandit and they are different between 80 & 82 on the Secondary drive and popellar shaft.

So what do I do????

[shortlid]

Me too

I though they were identical as well. Anyone on the board have any other thoughts. Spinning the rear tire to make it line-up ir making sure the bike is in N? Maybe new bolts would help and some anti-seize?

FINAL judgement

I got the ANSWER!

1979, 1980, and 1982 the drive shafts are all the same size.

for some stupid reason they decided to split the year 1981 and make the drive shaft a different size. so sometimes it fits, sometimes you have to replace the shaft like I will when it warms up

I thank greg at www.cycle-salvage.com in connecticut for his help
