2 valve gs1100--gs1000 top end swap

[acp4me]

hi .will a two valve gs1100 top end bolt up to a 1978 gs1000? are the rist pin sizes the same?. my bike needs a ring job. my neighbor has a 1100 parts motor low miles bigger displacement. larger valves and carbs. what do you think? thanks darrell

Swap the whole engine. It should bolt right in

The top end of the 1100 2 valve should fit the 1000 motor without any problem. Use the block & head together, as Suzuki added an extra bolt on the 1100 to prevent oil leakage in the front of the head gasket. You'll need the carbs. (They're better anyway) & an airbox that will fit the new carbs & your frame. One from a 1980 GS1000E should do the trick.
The entire motor won't fit. The 2 valve 1100 is a shaftie.
