you have already found it, this Technical Forum is where you need to believe.

Unlike some other forums, we do NOT have multiple forums dedicated to a single model of bike.
It is ridiculous, as nearly all engines suffer from the same exact symptoms, and the repairs are really pretty much the same.

A few wrinkles where one model has a unique part maybe, or the position that part is located it, but the symptoms are the same.

As far as belt changing video's I haven't seen any.. However I'd check YouTube to see what is there and also a member might come along with a link.. It's not that hard to do with just the shop manual as that's what I used.. I recommend the Clymer..

The charging system is the only real weakness on a 1200 especially the Fuelie's due to the larger, 500 watt, charging system and the connectors are the weak link on that due to heat and age.. First, what does the voltmeter read that's on the right hand side? It should read about 14-14.2vdc. You can check the battery voltage also which will be a bit higher at about 14-14.3vdc..

Next take a look at the charging system connectors. There are 4 to look at for signs of getting hot and burning: the Stator connector located to the left of the battery accessible by removing the side cover. Next is the 2 regulator/rectifier connectors. To access these you'll have to remove the fake tank fairing and it's on the center left kinda buried a bit.. The manual can walk you through removing the tank fairing also.. The 4th connector is on the starter solenoid and has 4 wires. The 2 in the rear of the connector are the hot wire and the ground for energizing the solenoid for starting.. The 2 red-red/white wires in the front of the connector are the ones that will cause problems as they carry most of the amperage load for the system and will burn!!

I have the same bike and I had problems starting with the stator connector burning. I wound up removing all 4 connectors, soldering/heat shrink insulating 3 new 12 guage yellow wires at the stator and doing the same with the regulator/rectifier wires. At the starter solenoid I clipped the red-red/white wires and soldered them to a 30 amp inline fuse holder, bypassing the 30amp dogbone fuse, and crimping/soldering a round end connector for connection to the hot side of the solenoid...

That outta get you started... Anymore questions just ask and we'll try to help out!!

Oh... I almost forgot... Here's a parts list you might find usefull! The fuel pumps/filters are for the carb's 1200's as are a few other things but timing belts, hoses and such are good numbers!

Good Luck with her!!

I recommend the Honda manual over the Clymer. Where is that hiding these days, John?

Ignore all the lines that are through those bottom part numbers. I didn't put them there and couldn't edit them out! They are good numbers!!

Also 2 extra manuals you might wanna get is the Limited Edition Supplement manual and also the 1985 GL1200 Electrical Troubleshooting manual!! Try E-Bay.. You should be able to find them there!!

Roscoe,
I removed all of the Strike Through marks from that post.
IF, you were using a laptop, the Strike through, and Subscript controls are in the Editor's control panel, just to the right of the Italics button.

Links are okay, even if they go to a hardly page, as long as, the topic is relevant.
