How to set the timing GL1000

Post by CamBam »



Hi, I bought a 76' goldwing. I bought it as a broken bike. The first thing I did was to remove the cylinder heads so that I could clean out the valves. I quickly did that not really thinking about the timing and how it should be put back together. So I am writing to ask how do set the timing marks? Im sure that the crank needs to be set at TDC. Other than that, im not completely sure how to do it... any help would be appreciated. Thanks!

Heads and cams installed? Safest way is to remove the belts, cams and carriers, or loosen them way out almost to the end of the threads of the six bolts holding the cams on. Then rotate the crank to T1. Then back the crank up 45 degrees or so. Keep track of which way you rotate it. Now the pistons are down in the cylinders you can install cams and carriers. Torque them down, then rotate the crank the opposite way to bring it to T1. Mark the crank up front because you'll probably move it installing the belts. Put the belts on. You should now be able to set the valve adjustments for the first T1, then rotate one turn and set the valves for the second T1.

Now time ignition.

You don't have to remove the cams, but you have to make sure no valves are open. Piston contact will almost certainly bend them.

Having the adjusters backed off makes installing belts easier.

Alright that sounds good... I haven't received my gasket set in the mail yet so I can't do it just yet. Just trying to gain the knowledge. Thank you so much!

Then you're fine. Whatever T1comes up with your pulleys having both "Up" marks up, becomes your first T1 to set valves. Do you have a manual to know the order?

How do I know if I am at T1 or T2 because all I see is "T" At what point in the crank rotation is none of the valves open?

If you had both heads off, it won't matter. You just get the belts on with the pulleys aligned at T1 and start setting valves. Then make a full rotation to T1 again and set the second set of valves.

The manual says to set the first set of valves when the T1 mark aligns just after the intake valve for cylinder #1 just closes.

If the "UP" marks are down you would be at the second T1. Cams are moving at half the speed of the crank.
