gs 1100 gs1150 cyl block,head and crank

[Anonymous]

hi

i have a 1980 gs1100et and i'd like to know if the block cyl ,head and crank from 1980 ,1981,1982 and 1983 gs1100 are interchangeable

the 1150 look similar can i use block cyl ,head and crank without modification except for the 20mm wristpin

i have 1168cc piston kit and i have to find another block cyl
( the 1150 look like the best choice it don't have to be bore to the last oversize like gs1100)


thank you

All 1100 and 1150 blocks interchange, just remember your 1168 pistons wont work on an 1150 crank cause of the 20mm wristpins.

And if you use the 1150 head on your 1100, you will need to use 1150 cylinder studs.

The cylinder head and crank are all interchangeable. The valve cover on the head is different. The cranks are interchangeable as we'll for the most part. I think it was in 83 they went to the big left end on the crank. Makes for a different magnet assembly on the end of the crank. You can use an 1150 crank and cylinder block. Or so I'm told. The wrist pins are different size than the 1100. If I'm wrong on any of this someone please correct me.
