5mm or 6mm sync kit?

[Magonsterz!]

Hi all, recent 79 GL project purchase. What size are vac sync ports on 1979 carbs? 5mm or 6mm? Swapping in a 1975, 22k mile long block out of donor bike and have already added Dyna ignition and spin on oil filter adapter. Going to utilize original running 79 carb and intake and want to try my hand at synchronizing after i set rocker arm lash. Should i set timing last?

You want everything else optimal before syncing carbs, Set the ignition timing before the carb sync.

You want the 5mm kit.

Xcllnt thx much appreciated couldn’t find online.

Got it, lash, Timing, sync thx again

update, set lash yesterday after work.
Ordered 5mm synch kit

Going to install enginge this weekend and set the timing.
engine was said to of had less than 25k, how many miles does a stock clutch see before rebuild?

[DenverWinger]

Clutch will often last the life of the engine (100,000-200,000 miles) but that depends on how the driver uses it. With only 25k miles that clutch should be almost new.

great news, can that be said for the stator? cycle has been stripped and only running gauges and headlamp.

[DenverWinger]

Biggest killer of stators is short circuits and bad connections, namely the stock connector by the battery. Most people simply cut the connector off the wires and solder them.

On the GL1000 they are pretty much trouble-free. There is no such thing as a "Preventative" replacement. If there's an electrical problem a new stator can be killed just as fast as a working original one.

The amount of electrical load on the bike doesn't affect the actual load on the stator, the permanent-magnet alternator gives full-output at all times, and excess power is shunted to ground by the regulator. Reducing the load on the bike actually makes the regulator work harder to maintain correct voltage.

great info much appreciated! Guess im safe to swap in and HID headlamp.

The stock connector by the battery? The positive cable to the solenoid?

No, to the left (front side) of the battery as you are looking at it the bike originally comes with a connector that the three yellow wires from the stator pass thru. That one. If you can't find it and the stator wires go directly to the bike's wiring harness someone has already eliminated it.

light bulb on! gotcha will inspect this evening. thx much, really looking to improve and remove any already known, possible gremlins. On a mission!
