Setting valve lash

Postby echinus1988 » Thu Apr 14, 2016 6:02 am



Once again I find a question the book doesn't address.

The Clymer manual says rotate so the T is on the line. Set for #1 cylinder and ... Rotate 360 degrees to the T again and set the other valves.

My question is, what is the marking that I took a picture of? It has a two with a T above it. And that is where the valves for 3 & 4 appear top dead center.

I'm confused. It make sense to hit the T 1 mark but doesn't look right at the cylinders. And what is the T 2 mark used for?

Nothing I know of maybe on an engine rebuilt setting crank before installing rods??? ...but 2-f firing/timing 3 and 4 ..although you can't adjust timing on an 1100???? just check it..

Well, I set my valve lash and took it out for a ride.

Well, it runs worse than it did before adjusting valve lash so it's back in and recheck all my measurements again. Make sure I didn't screw it up!

Thanks for the help.

Complete instructions..not mine..from Steve

Engine must be Stone-Cold . . . that's overnight-cold.

1. Remove the valve covers by loosening the four 10-mm bolts evenly and in a diagonal pattern. This helps to avoid distorting the covers.

Orient yourself to the piston numbers. The first time on an unfamiliar engine it's good practice to make numbered masking tape labels and stick them near the set of valves for each cylinder.

2. Remove the spark plugs. Remove the timing mark cover and rotor bolt cover.

3. Place a 12-mm offset-box-end wrench on the rotor bolt. Rotate the engine clockwise until the intake valve on #1 cylinder opens and closes. Pull up only! You do not want to loosen that rotor bolt. #1 Intake is the upper valve on the right front cylinder.

4. Continue rotating until the flywheel's T-1 mark is aligned with the index marks on the case. #1 is now at TDC (top dead center).

5. Check the clearance on the following valves by running the correct size feeler gauge between the valve stem head and the adjusting screw.

#1 Intake - - .004” (.1 mm) - - - right front, top
#1 Exhaust - .005” (.13 mm) - - right front, bottom
#3 Exhaust - .005” (.13 mm) - - right rear, bottom
#4 Intake - - .004” (.1 mm) - - - left rear, top

6. If the gap on a valve is incorrect, loosen the nut with a 10-mm box wrench and screw the adjuster in or out with your screwdriver. Use a light touch here and don't push in on the screwdriver. Turn the screw in until the feeler gauge won't move, then back off slowly until it just starts to move. You want just a little resistance to movement here. When it's correct, the next size larger gauge will not easily slide in and the next one smaller will be sloppy-loose.

7. When the adjustment is correct, tighten the nut while holding the adjustment screw in position with the screwdriver.

8. Torque the locknuts to 9-12 lb.ft. (1.2-1.6 kgf m) and re-check the clearance on #1 intake and exhaust, #3 exhaust and #4 intake. Adjust any that are incorrect.

9. Rotate the engine 360̊ clockwise until the T-1 mark is again lined up the the index marks. #2 piston is now at TDC. Check and adjust the clearance on the following valves as you did in Steps 6 & 7.

#2 Intake - - .004” (.1 mm) - - - left front, top
#2 Exhaust - .005” (.13 mm) - - left front, bottom
#4 Exhaust - .005” (.13 mm) - - left rear, bottom
#3 Intake - - .004” (.1 mm) - - - right rear, top

10. Torque the locknuts to 9-12 lb.ft. (1.2-1.6 kgf m) and then re-check the clearance on #2 intake and exhaust, #4 exhaust and #3 intake. Adjust any that are incorrect.

This part is not required but a double check..

11. An additional check should be done at this time as described in Steps 12 -15.

12. Rotate the engine 360̊ clockwise. #1 intake will open and close. Align T-1 to the index marks. #1 is now at TDC. Check #1's intake and exhaust valve clearance and re-adjust if needed.

13. Rotate the engine 180̊ and align the T-2 mark. #3 is now at TDC. Check/adjust valve clearance on #3.

14. Rotate the engine 180̊ and align the T-1 mark. #2 is now at TDC. Check/adjust valve clearance on #2.

15. Rotate the engine 180̊ and align the T-2 mark. #4 is now at TDC. Check/adjust valve clearance on #4.

16. Inspect, clean/replace gaskets and refit the valve covers. Torque the 10-mm bolts to 6-9 lb.ft. (.8-1.2 kgf m) evenly and in a diagonal pattern.

17. Inspect, clean/replace O-rings and refit the timing mark cover and rotor cover. Do not overtighten!

18. Go for a ride and enjoy the weather.

NOTE: Valve clearance varies on GL1000 and GL1200. Consult your manual for details. Also, on a GL1000 you should follow this with ignition points and timing adjustments.

Now, a good carb. sync. is probably in order. Click=>> Randakk's Carb Synchronization Procedure.

I'm redoing the valve lash tonight. I like the suggestion of next size up won't fit, one size down will be sloppy.

Plus I'll do the recheck and make sure those are correct since I didn't think of that or see it in the instructions I had.

Thank you for the help.

Won't ride tomorrow since snow is predicted for tonight.

Did you have a look at How to adjust your valve clearances?

Yes I did. I printed it and have it for reference. I went out and used the book since it had a full section on adjusting. I'll use this guide this time.

I went through things very carefully I thought but the bike miss fires whenever I use the throttle now. So I am assuming I did it wrong.
