1984 GS 1150 engine into GS1000L frame

[LA_Mike]

Hi

I wonder if a GS1150 engine made in 1984 will fit into a GS1000L (1981) frame without doing any major mods. The reason being is that my GS1000 engine gave up and it seems to be more cost effective to swap the whole engine instead on trying to rebuild the old one.
Did anybody attempt this in the past ? Can it be done ? [-o<
I looked through the messages and only found 750/1000 swaps ...

If it had been an '80 GS1100L frame it would be a bolt in...but in '81 they dropped the 16 valve 1100L model. It can definitely be done, but you may have to make some motor mounts which are not that hard to make.

Isn't the '81 1000L a "shaftie" ? ( I think '79 was the only chain drive 1000L ).

May be tough going with a 1150 chain drive engine.....

That may be the case but the model chart indicates that there was a chain GS1000L in 1981:

If Greg is correct (and there is a very good chance he is) then the shaft would be a huge problem.

Greg is correct, the only 1000L that was chain drive, was the semi rare 1979.
a 81 1000L is going to be a GL shafty.

Oh no, you guys are absolutely right. I have not driven this bike for a while since I have a newer one as well, but you are correct it is shaft driven.
I guess now I'm toast - I've found a decent GS1150 engine, but it will do me no good. I think it might be possible to change the rear tire and such
and take out the shaft link all together.
This sounds like a lot of work and I need to buy many more parts to make it work - if the engine even fits in the frame with making new motor mounts as somebody mentioned.
Basically it is bad to have an older shaft driven vehicle in a sense that the parts supply is very limited ...

I might have to shoot the bike since I'm not able to spend a few thousend dollars to make it work again.
