Project GS1000 with GS1100G D-Port Head, 1100G Cylinder & Mikuni RS34

[Sci85]

Wow, amazing build out. Too bad you have a long wait until next ride huh?

Quick question, when dropping on the cylinder, how do you get all the rings compressed at the same time while also lowering the head? I've done it on single cylinders before but never 4!

Thanks,

Beautiful paint job!

In pairs.
With two hands and a helper pushing down the cylinder.
I have done it by myself by tilting the cylinder on the way down. Much easier with help though.

Installing the cylinder block

Use 4 Terry bands of the right size that you can screw around the rings on the pistons just enough to hold the rings flush with the pistons. Then place a new gasket on the crankcase and lower the cylinder block on the threaded hold down shafts slowly. Two pistons will be UP and two will be Down. As you slowly push down the two Terry bands will slide down as the two pistons engage their bores. Once the rings are seated you can remove the two Terry bands. Do the same for the other two pistons. I have done this on many bikes including a Honda CBX 1000 6 cylinder.

What did you do to get the cylinder block and head looking so good? Bead blast and paint? What paint did you use?

[Sci85]

Terry bands? Not familiar with that term...

Another amazing build thread, it was a treat to read and I enjoyed your skill and attention to detail.

Great job!

Question, will my GS1100L top end. Fit my GS1000E block? Gotta 82 GS1100L shaftdrive motor,run's like a top. And I have a 79 GS1000E motor thats tired.If I take from the pistons up/jug's an all.Will it set on my 1000 block/crank????

[GS1100EGS1000E]

Amazing! You guy's have shared a tone of information. And the pic's are perfect as well. This 1100/1000 rebuild will be the first of what I hope will be a great learning and great fun filled journy.With more bikes to come.We both are inlove with the GS/E model's.He started back in the late 70's with a 1979GS1000E. That bike started the addiction with the both of us. We now have his GS1100E 1982,the only thing is.It does'nt have the correct motor.So we want to repace the 4 valve 1000E cylenders/topend. With a set of GS1100L 4valve cylenders/topend. Your knowledge and photo's are awsome. Thank you, and again. AMAZING WHAT YOU DO WITH YOUR BEAUTIFUL BIKES.

Welcome to the Site GS1100EGS1000E

So you have a 1982 GS1100L 2V and you want to transplant the cylinders & head on your 1000E. That will bump the displacement up to 1074cc. (In my project I used Wiseco 73.5 pistons to yield 1100cc). It should just drop onto the 1000E block but since I have not performed the modification your contemplating I cannot say whether it will work. . . . Worth trying.

The later model 1983 & 1984 1100G's head had the D port head which boosts low end torque . . . should be the same on L's? (No comments Tkent02). Look in the exhaust port to determine if its D shaped.

Another option is the tried & true Wiseco 1085cc 10:25CR. Look forward to seeing your project.

just re read this and wow. steve great job on the bike and the info sharing. i sent you a pm about a head.

thanks

Matt,
Looking through the Inbox I never saw the request. In the interest of keeping this information in front of new GS projectters I figured to give it a bump too.

How has this 1100CC build held up since you did it and what do you ultimately think of it vs. the 1085 kit that you had previously? Did the swap achieve your goal of more low end torque?
