QUESTION: Cam setting instructions needed - 1982 GS1100

I need instructions for setting the cam timing marks on a GS1100.

RIDER: David Johnston

REPLY: Frank Perreault
The camchain tensioner should already be out.

1) Remove the side timing cover and rotate the crankshaft clockwise until the "T" mark for the Number 1 -4 aligns with the mark.
2) Lube the journals and bearing surfaces on the exhaust cam (marked EX) with assembly lube.
3) Take the exhaust cam and slip it through the cam chain with the notch on the end of the cam facing to the right-side of the engine.
4) Position the chain on the camshaft so that the arrow on the side of the cam sprocket is lined up with the gasket surface of the cylinder head. (facing forward). Make sure no slack is in the front of the cam chain and that the mark still lines up.
5) Install the inside and outside bearing caps. The letters in the casting of the bearing should match the number stamped into the cylinder head. The triangle faces forward. Torque bolts to 6-8.5 ft. lbs..
6) Lube the journals and bearing surfaces on the intake cam (marked IN) with assembly lube.
7) Position the chain on the cam sprocket so that 20 chain pins are between arrow 2 on the exhaust camshaft sprocket and arrow 3 on the intake camshaft sprocket.
8) Install the inside and outside bearing caps. The letters in the casting of the bearing should match the number stamped into the cylinder head. The triangle faces forward. Torque bolts to 6-8.5 ft. lbs..
9) Install the cam chain tensioner.
10) Adjust the valves.

Post deleted!!! It is LATE, I had a LOOONG day & I am operating on only 5 hours sleep in the last 2 days. 20 pins IS correct! I had to go dig out my 1150 manual when I came back here & saw your post Terry! Thanks for the correction. Elvis has left the building, good night! Ray.

Nick, I am planning on degreeing the cams however money is getting pretty tight atm, so I'll probably do it after the first 500 miles of the initial break in period.

I don't feel comfortable slotting the sprockets myself so will need to get an aftermarket pair. Also, I need to get a degree wheel and TDC gage/tool. All said around another hundred or so shipped.

I've got a couple other items on order so can't quite swing it for a month or so, which will give me more than enough time to start her up and get a few miles in (weather permitting!!!)


For now I'm using my stock 1100 Sprockets with the 1150 cams. Everything is lining up good and it appears I should be OK for the mean time.





And Ray,

I went back up to take a look after your post and actually I WAS off on the timing. I hadn't fully tightened down the tensioner and/or bumped the crank... Once the slack was taken up my alignment was about 2 teeth off counter clock wise.

I have some CNC slotted stock cam sprockets if you are interested. I can send them to you for 40 bucks shipped to you. Let me know, Ray.

[niclpnut]

Thanks Ray.

Well yesterday and today I got the cams degreed in. I'm sitting right at 105.5 and 107.5.



Took me some time, but after triple checking I ain't gonna move it no more!

Guy in my neighborhood had an 82 1100E that he was going to mod. However, he lost interest in the project and sold his bike (good condition and RUNNING! for $350). I asked him if he had any extra parts and he gave me a set of slotted sprockets that he never got around to using. Might still hit up Ray for another set that will eventually go into the red bike.

Just finished checking the valve clearances and I'm set on the fat side of .04.

Real gasket install, which is actually kind of a pain since it's wiggling all over the place.



Sprocket conversion kit got here today! Went 17/48.



Started breaking down carbs to install new O rings.



Carb body interiors are super clean.

Lookin' good!

two things

#1 THROW AWAY THAT REAL GASKET IT WILL CHEW UP YOUR CAM GEAR. Dont use it on 16V motors

#2nd you might find this method interesting to improve the accuracy of the measurements so you can get the degree adjustments dialed in faster.

This bike has an electronic tach, so no gear to worry about.

From my research I should be OK using the Real Gasket.

Without a mechanical tach, the thicker Real Gasket doesn't cause an issue?

Sorry ; I forgot you had an ESD.

I see there is no tach gear; are those stock cams or 1150?

Edit: OK you got the 1150 cams from Nick

[niclpnut]

1150.

It appears that the new 530 chain is actually 116 link and not 114.

Not sure why I was counting the links (well it was about 2 am and I had a few too many)....

Also not sure if it was my error in ordering or the vendor's.


Anywho, guess I'll break the 2 extra links.


Nic

[Nicholaschase29]

On my chains I grind down the pin with a air cut off disk and then pound it out with a punch. Works like a charm

[niclpnut]

Yep, same here.

Chain lengths are counted by the links...including the master?

[Nicholaschase29]

I mocked it up and then cut it to fit rather than counting links and doing the math... So i'm not really sure.
