I think the 80-82 750E exhaust cam is the same part number as the 80-82 GS1100E exhaust(6.5mm lift), while the 1100E intake is a bit more than the 750 (7.0mm lift).

Unless you have someone to show you how to degree the cams, you might be better of just dropping them in with stock gears.

getting adjustable sprockets will probably not be a do it once and forget it ordeal. The opportunity to try many different combinations of cam timing will be a great experience. - coming from a tinker n tune kind of guy.

I have a set set at 105 int and 115 exh the piston to valve clearance is still over 0.100" int and 0.120 " exh. (total W.F.O.)

most cam mfg. advise to run 108 sometimes 110 on either and/or both. very safe so that things do not hit each other at redline.

why not degree them with the stock sprockets in the stock timing position verify the lobe centers and check all the piston to valve and valve to valve clearances then make the decision.

mine is a 83 750 ed, im not new to rebuilding motors,or timing stuff, ,but its nice to know from ppl that have dont it first hand,and what works,so theres no guess work
the stock cams i have are great, bike screams , but i would like the rumble, of a performance cam,and some more power everywhere
will the 1100 cam gears work or use 750 gears?, i dont know the sizes ,or distance from cam to crank stuff

Someone on here will know .. but I suspect you will not see an improvement from the stock 83 cams to older 1100 cams.

83 750? Huh I don't know? The 1100 and 1150 cams do swap, but I dont know much of the 83 750 internals. It probably does but as mentioned the lift may actually decrease.

If you are going to degree your cams then this works very well.

BikeCliff has the 83 GS750ES manual on his website; It is 148 Mb or so . The lift is 7.5 intake and 6.5 exhaust. That means the 82 GS1100 lift is 0.5 shorter on the intake side. So for perfromance you are going backward.

You need 1150 cams at 8.0/7.5mm v.s. yours ar 7.5/6.5mm (Int/Exh). BTW the 0.340 webcams I have are degreed 105/107 (IIRC). I could have gone to 0.348's but if you want to keep the power low and retain the mid range this seems to be better. Bill had his degreeed at 110/110 and it is more like a light switch at 6K. No so much mid range then it all comes on at 6K

what about the duration???

The 1150 cams do not have provision to drive a mechanical tach....the 1100 EZ/ED do. If your '83 750 has an electronic tach, it won't be an issue, otherwise you will need to plan on losing the use of your stock tach.

Tony,
I'm pretty sure that 83 750 has electronic tach.

Cool, that was the only issue that kept me from dropping 1150 cams into my bike. Both '82 and '83 1100 EZ/ED intake cams have the same lift (7mm), so he would be going backward (performance wise) with either 1100 intake, I believe.....only the '83 1100SD Katana got the hotter intake (.5mm more lift at 7.5) which is the same as his stock '83 750 intake cam.

According to the various manuals the 80-82 1100E's are 7.0/6.5 mm
while the 83 GS1100E are 7.0/7.0 mm. However based on two different sets of cams I have the 83 ED/ESD manual is wrong as the cams seem to be 7.5/7.0mm which is the same as the 83 GS1100ED big Kat.

The 1150 are +0.5mm on both cams 8.0/7.5 mm.

Okay Jim, even if you are correct, and Suzuki is wrong, I think we can agree that he would be, at best, matching the lift he already has with his stock intake cam, and benefit by .5mm on the exhaust side with 1100 ED/Katana cams.....1150 cams would be the way to go.
