Old timers (I'm one BTW) remember when having an oil filter, was a luxury. Every time I service my machine, the filter gets replaced. Most any filter will do IMO. In 2020, oil filters have been around for decades. Filter & Oil technology has been in step all along.. My father gave me his PowerPa...

I'd be concerned about it ending up somewhere that resulted in it causing a problem of some sort.. pc

If most of your riding does not involve many miles per trip, I'll suggest using a POA base. If you run a lot of miles, the synthetic of your choice should be considered. Why.. POA based oils tend to maintain a cleaner engine. Synthetic oil is excellent (it's actually better than most realize) but te...

FWIW.. if anyone needs a Superbrace let me know (I got one, thinking the Blackwing Brace was history.) pc

FleeBay has the BLACKWING (GL1500) Forkbrace available @ $60 .. pc

Friction Modifies are not designed with wet clutch's 'in their' spec.
A little added cushion in a clutch design, goes a long
way in prolonging the useful life of the drive line..

I'm also curious about how friction modifiers adversely affect the performance of a wet clutch - is it a matter of permanent damage to surface of the clutch plates, or more of a temporary issue that can be resolved at the next oil change? Thanks in advance to who ever might be knowledgeable and hel...

This site isn't the location to discuss using additives. No place is. You either have an understanding of lubrication or not. If you want to carry-on with this subject, let's PLEASE open a new thread or better yet NOT.. pc

FWIW..
I used Lucas in my B' Series Dodge Dually for almost 400K w/T6 and never had any issues, pulling whatever, all over the country. Then again, a Goldwing isn't a diesel or a rig pulling a 40' float.
Still have the Dually btw.. (for sale & I'll kick in the float.) pc

Give the relay a check..
sounds like you are getting close to the issue. Good Luck pc

If you have not replaced the harness/switch yet..?? Why not TRY to clean the old switch. My switch was in the same condition (it would not turn off.) I disassembled and cleaned (CRC Contact Cleaner) and lubed, now all is nominal and I know how to fix the switch when I turn 95 (right.) BTW, check the...

Lucas claims to be 100% petroleum based (i'll guess w/no modifiers or it would have been noted.) pc

Check for a vacuum leak... hopefully it's a hose. Next attempt, would be to snug-up the all of the carb fasteners. Use your preferred carb cleaner (i like MMO) and cross your fingers while you allow it to do it's thing. Good luck, because, rebuilding the carbs is around your next corner.. pc :ugeek:

Why did you decide to replace the switch assembly?
Did you have any thought of trouble shooting and repairing the OE piece.
Typically (IMO) replacing things with used equipment isn't that positive unless the OE piece is complete junk.

After 60 plus years of riding, my balance became a issue over a period of years. I thought it was back surgeries, heart surgeries, eye issues, joint replacement or being in my mid-70s. NOPE... Vitamin D3. I got lucky and found a old(er) Doctor that suggested I investigate the results of aging and nu...

SKF 9879 SEAL/Honda has one too (if you got lots of $$$.)
Seal for the alternator drive. (less than $10.00.)
When this seal goes away the alternator gets wet (w/oil.)
BTW, this seal has nothing to do with the Alternator O-Ring Seal. pc

This thought crossed my mind. :idea: In lieu of all of the ongoing alternator issues. I used to think that upgrading a battery from a OEM battery to a improved design battery was a good move. Then... I remember a service bulletin referencing the idea and the (sometime) problem it created. Seems that...

A GL1500 is at least 20 years old.
New cables are cheap.
Why not just replace them?.. pc

Switches are available, check typical sources if you have issues cleaning the old pieces.
Most any of the dielectric greases should last for decades.
De-Tox-It (sp) cleaners etc., are good... pc

With the age of the bike.. sounds like valve guide seals. Who knows? Buy, beg, borrow or steal a leak tester and confirm cylinder wall condition with a peek into the cylinder's. Smoking that dries up (eventually) would force me into enjoying the ride and living with the smoke and pretend you are rid...

I'm not up to speed on why Progressive Suspension put 416-1633gla PN on their GL1500 Goldwing shock. Try directing the question to PS. I'm curious why PS suggested adding the HD spring set to improve the shock and played the game of not giving the spring PN. Since there are 3 different spring's conf...

Corrosion has reared its ugly head..
unless you have a mill to make a sleeve,
seems getting another MC is in your future.
Please note; I am not up to speed with a 1100
(but.. brakes are pretty much the same hopefully.)
Good Luck

pump up the brake and hang a weight on the rear pedal lever.. overnight.. then bleed it in the morning,
if you are still having problems. pc
