What order?

[Guest]

I have my 1982 GS1100GL engine back together and firing on all four. Now I want to dial it in but I'm not sure what order to follow. I have all the toys, (i.e., Colortune, Motion Pro SyncPro, timing light). Does it matter which I do first? My plan is the following order:

Timing
Carb sync
Mixture

Any thoughts? Thanks.

Your timing is factory set, so you can confirm it at least

Otherwise, you are correct, providing the valves are adjusted

I did an overhaul of the engine; valves, cylinders, rings, etc. I adjusted the shims during assembly and they are all within tolerance. Because of the tear-down I thought checking timing would be necessary.

Ignition timing would only be disturbed if you moved the plate at the right end of the crank.

As you assembled, you should have verified (several times) the valve timing.

After that, I would open the mixture screws on the carbs to about 3 full turns out to ensure they are running rich enough (easier to run than if running a bit lean), then warm up the bike, do a carb sync. While the gauges are still connected, do a mixture tune. As you lean each mixture screw, the engine will slow down a bit, causing the vacuum to drop in ALL the gauges. When it drops, turn that screw back out about 1/4 turn, go to the next carb.
