tips needed

[posplayr]

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.
Tony.

Yea we agree, the 1150's were my original suggestion

Here is another example of 83 1100 cams that have over 7.0mm lift on the intake. They could be 83 big kat cams but not near as likely as 83 1100ED/ESD cams.

If it hasn't been answered you'll need to use the 750 cam sprockets.

Well I for one was not sure if all these cams interchange; so I guess they do with the 750 sprockets. Same go for the older 80-82 GS750E's (I mean sprockets)?

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

no not electronic, but it did act like it was a few times,
the rpms were erratic but its mech tach
i cant believe the 700 and 750 have the same lift as the 1100, i have a factory manual ,and the lift is identical for the 700-750
and the 1100 has a lot biger stroke,and duration will be dramatic i will need to measure both side to side
but thats why i asked you guys /someone that knows for a fact from doing this swap

Jadesystems reported that 83 700 and 73+ 750's were electronic. I guess a 83 750E was mechanical?

Realize that the lift on the GS's was pretty conservative. Performance cams pretty much start at about 0.330-0.340" lift with 0.348" still very streetable. It goes up from there. The oil cooled GSXR up to about 1992 ran high lift cams as around 0.350 IIRC. The GSXR 750 was a real hot shot designed like a race bike for high reving. In certain years I think the GSXR 750 even had bigger carbs (38mm) than the GSXR 1100 (36mm). The GSXR 750 reved mush higher than the 1100. So this GS700/750 were precursors to the GSXR and were pretty hot little motors compared to the earlier 16V 80-82 GS 750's.

Yeah, Web Cams for the GS1100 start at 0.348" and go up from there, all the way to 0.410" I think.

Actually they start at 0.340; that is what I have. The lowest aftermarket is 0.330 but dont have the manufacturer off the top of my head.

They are pretty mild. If you want hotter then go 0.348.

FYI with a 1168 Weisco BB kit and the 0.340's my GS1150 carbs have 147.5 Mikuni jets and I get about 33-35 mpg typ. I'm sure it would continue to drop going 0.348's. But if you are doing street/strip 0.348's are the way to go over the 0.340's.

[doctorgonzo]

I didn't see the .340" on the APE page, they may be available elsewhere, or I might have missed them. .340" would actually probably be better for me. Not sure what I'm gonna bore it to, but doubt I'll go new sleeves, so I think 1168 is the max. I'm still doing my research on this bike.

Hijack over.

They are still available. Also some baby 0.310's

Contrary to what Webcams claims, the 0.340's are considered drop in with APE springs. Both Bill and I have them and see no noticeable wear with a few thousand miles. I do have a top end oiler though.

One unfortunate occurrence with my bike was my sacrifice to the GS charging gods. While doing testing on teh FET based R/R's I smoked my cams and head while idling. It was OK as I has a new ported head on the way, but I was not planning to drop another $400 for cams during my last 1168 experience.

If you do a Weisco kit DO NO USE THE MLS GASKET there are TOOLING ISSUES WITH THE GASKET. IT IS DEFECTIVE

my 750 has a screw on cable for the tach, i have nt got it apart though won do that until spring, im just researcvhing this studff, i am having my foot fused this month, no pressure on it for 3 months!,and in a boot for 3-4 months!!
so i cant do squat,but talk to you guys lol

any way to tell what year ,and brand my 1100 cams are for sure??? i got them today,from oink

[mriddle]

I have never seen an 83 GS750E have a cable driven tach

Can we see what it looks like ?

[cyclefvr2]

look up the micrfiche

[gearhead13]

look up the micrfiche

I looked up an 83 750 at bb and there is NO tach drive. Are you sure its an 83? How many bolts on the valve cover?

[Billy Ricks]

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

1100 cam gears won't work, different number of teeth.

[Billy Ricks]

Are you sure that's not the speedo drive? Guys with '83 750Es used to drop in a 700 exhaust cam for a little pick me up. Suzuki changed the 700 exhaust cam to work better with the shortened stroke.
