You will have a detuned 1100 with the 79 cams in there. I know you need them for ignition, but 75-77 cams have more lift and duration.
Yea Looking for a set. Ebay is nuts with some of them. Where can I find the Lift and Duration figures to compare what I have though ?

In the Shop Manuals. The lift isn't much difference, but duration is.

Thanks for trying, I looked for stock cam specs for the 1100 and couldn't find ANYTHING

However, knowing that I have a DE-tuned 1100 engine now... is nice....

I Have NO idea what was wrong with the 1000 but something was BIG TIME wrong with it. I always thought it was way slower than the dressed 1100 I rode in high school, even when the 1000 was naked.

I took the bike out for a little spin last night..... HOLY horse manure Bat Man, this thing runs good.....This is what I remember a Gold Wing running like. The extra gearing in town is GREAT but I want to get on the highway and see what shes like before I make a definite judgement on it.

Any reason I shouldn't run D8EA plugs like the 1000? Since the ignition system is from the 1000! Don't see why I need resistance plugs

still thinking the timing is too advanced because it starts so hard. Reminds me of a high compression smallblock we built for a dirt track car in high school.... ERRRRURRRR ERRRRUR.. could be the starter though. Using the one off the GL1000 because the 1100 was bad.. but the 1000 had no problems with the worn out 1000 engine

Pulled the 1100 starter apart last night. Everything is fine but the gaskets and Brushes ..... found the Brushes but I cant find the gaskets without buying a kit that has everything in it ...Paying 40$ more for overpriced bearings that I don't need ..... anyone know where I can get the gaskets from?

Got some exhaust leaks but that's easy enough...
Good so far.

Those plugs are OK, same thing in the 81-82 1100s. What gaskets do you need for the starter? The only "gasket" it has is the o-ring on the nose.

With no God over the state, the state then becomes not the defender of liberty but the definer of liberty.

If I disagree with you it's simply because you're wrong.

That kind of hard starting might be caused by a liquid getting into a combustion chamber.

Why ain't we ridin'?

Year.

75-77. 5 50 50 5. Intake and exhaust 235 duration
78-79. 5 35 40 5. Intake duration 220 exhaust 225
80-83. 5 43 45 5. Intake duration 228 exhaust 230

At wot, above 5000 rpm most feel 75-77 make better power than 78-79. The 1100's were in the middle and had the extra 25cc's to boot.

Dave, Gaskets on each end, well not 100% sure on the gear end but it looked like gasket material stuck to the gear housing what was left was "fiberous" not like old grease, the one on the armature end is/was definitely a gasket. Cleaned up all the internals and did a slight resurfacing of the commutator. The Pos (+) Brush had no insulation covering the wires but the brushes are short anyway so the new ones will have it. So at least one gasket and the brushes I should be good to go.

Hadnt thought of it but once I find gaskets I will check the 1000 starter and rebuilt it too, so I have a good one on the shelf.

Dennis it could be but I don't think it is. You can turn it off and immediately try to start it and get the same thing.
bike doesnt smoke at all. Well 3 sec when you first crank it up from the side stand. meaning normal.

Ekvh1 thanks for that, thats not an inconsequential change... actually the early cams are closer to the 1100s than the 78-79s are.

thanks again
