1100 motor

[monte]

Just installing a 1982 gs1100 motor into my 81 gs. only difference I can see is two additional rocker cover bolts at the front. Are there any internal changes between these years? tks anyone ..Monte

The cams changed in either "82" or "83". In mid "82", they started welding all the crank pins, except the one at the primary gear.

1100E or 1100G?

If it's a G, I don't know about the bigger engines, but on the 850 the driveshaft flange is very very very very slightly different between the 79-81 engines and the 82-83 engines. We're talking a very slight yet crucial difference in the spacing of the bolt holes. Guess how I learned this. Just guess. Imagine the things I said...

Anyway, if you are in fact working on an 1100G, then triple-check to make sure you have the correct driveshaft.

If not, then never mind. I don't know squat about 1100E models. But you might want to make future posts a little clearer re: the exact model you're working on, or put them in your sig.

If I remember right, the "81" G was a GS1000G, Don't have a clue of the differences in it & a "82* GS1100G eng. maybe 100cc

He's talkig about the 16 valve 1100. The 81 and 82 are pretty much the same. The cam setup is a little different on the 83 and as noted sometime during the 82 production they strarted welding cranks.
