Has anyone got a tutorial with some pictures (or without) on how to Timing Chain Slack Adjustment?

GL1800 should adjust automatically. It has a spring loaded tensioner. I suppose if you had a heap of miles on it (200k or more) you might be right, but I've not heard of any issue with chain tensioner unless it is faulty or flat wore out. If you're new to the 1800 you might be hearing the injectors clicking, try some Lucas fuel additive, they quiet right down and clean the injectors nicely. My 02 has almost 100k and haven't noticed a single issue with anything short of an occasionally stuck switch. Also use a good name brand fuel (I like Chevron and Shell), with the falling prices there is little reason to skimp, Chevron cleans the engine nicely with its techron additive.

What I really hear is like a thumping rattle that usually occurs when I lug it when warmed up.
I really cant describe the sound other than like a shaft in the gear box with a bunch of side play where it is rattling around.
I tried using Lucas Synthetic 20-50 oil hoping that when warm the rattling would let up but it is the same.
It could be that the sound is normal to 1800 Goldwing as this is the only one I've ever rode

Hmmm... First The 1800 Shouldn't Be Lugged. Shift Above 2000 Rpm, Around 2500 Is Manual Spec. I Use 10-40 Mobil T1 From 5 To 125 Degrees F Without Issue. The Lucas I Use Is The Additive For Top End Lube And Fuel System Cleaning.The Small Bottle WillTreat Three Tanks. I Only Use It About Every Fourth Tank Less I Get Chevron. You Might Visit A Dairy Queen And Listen A Few Other GoldwingS. Lol Pardon The Caps, I'm On My Phone!

A PastoT said "do not lug the Goldwing engine", what's going on is the engine when lugged, is fighting with its compression stroke because it is not getting enough power to overcome the compression and pull the bike at the same time, always keep it above 2000RPM or you will destroy it, rods or crank bearings or both. In town shift down, on the road give it enough power to pull the load and it will last 3-500000 mi just with lube and love, TLC for short. :mrgreen:

Hello all, hope you all are doing well..
i have been through this topics and similar since i think, this is the same situation I have with my 2008 GW 1800 with 38000miles.
actually is not a big issue, but with a so perfect bike ,sometimes is annoyng ,since it comes uo any now and then.

I could note identify any good tips reading the threads so my question ( if i missed that in other topics) is there a method how to identify if the rubbing is coming from chain rather than alternator?
in any case ,is there anything can be done to dump down that?...any suggestion?

thanks

I'll help you. Can you make a video of the noise, post vid on u-tube, and post the link to the vid here for others to hear ??? Hint ... if you cannot hear the noise in the vid, neither will anyone else.

If the noise is under load, center stand the Wing, make sure the rear wheel is off the ground, and "power brake" the rear wheel to make the noise. Be careful ... don't burn up your clutch.

My guess says it is ADG (alternator drive gear) noise.

Hi all folks
Even if long slow reply ( difficult for me to access my bike during covid time) I managed to start my riding season again and again I am back on this issue. Actually ,it seems you were right!
By tracking the noise , I came to conclusions that alternator is the guilty, probably the bearings.
I wish to overhaul it so I am looking for the ball bearings and the brushes.
I could identify the original OEM I'd numbers but now I would like to find the bearings type and dimensions to buy them from a normal bearing shop ( from Honda the price is unacceptable for such common spares)Also brushes dimensions I need for the same reason.
I could take the old ones as a sample reference, but we are in riding season and would like to have the parts in my hands before dismantling the alternator

Does anyone have such identification infos?...thanks

I don't have numbers or sizes but you can get brushes from cyclemax in Ohio and also get oem bearings from them on the oem side of their site. As far as expense goes you may be right about the price but you can not beat Honda's oem parts. I rather pay now and not worry about it again.
