GL1100 Transmission Issue

Post by ewhadley81 » Fri Oct 13, 2017 10:29 am



Hello All,

Not long ago, I started having issues with my '83 GL1100 transmission. I did have an occasional issue with going from first into second, and even second into third. It seemed like it did not fully engage into the next gear. I would simply up-shift again, and it would go into gear. I did not think much of those occurrences at first, as they were sporadic and rare. However, more recently, the transmission has a major issue between fourth and fifth gears. The bike sort of shutters when I'm in fifth gear, and it even decelerated when I open the throttle more. WHAT?!?! That's exactly what I thought when it happened. I had no clue what was going on. I slowed down some, down-shifted into fourth, maintained that speed for awhile, and all seemed okay. I up-shifted again, only to have the same issue occur.

I spoke with a friend of a friend here locally (he currently owns two Wings - one 1500 and one 1800). I mentioned " my '83 Wing has some kinda transmission issue." Immediately he asked me, "is it between fourth and fifth gears?" He said that is a common issue with older Wings. "Ride it til it dies or get rid of it now," were his exact words.

So my main questions are this: Should I get rid of it now? How difficult is it to fix the transmission on a 1983 GoldWing Interstate? I am somewhat mechanically-inclined, and have worked on my own Wing on other matters. (Replaced the water pump, replaced both tires, misc other stuff.)

It currently has under 70K miles, and I have always enjoyed the bike. I don't really want to get rid of it, not unless it will be a major hassle to fix the transmission. Can you educated folks here help a guy out, please?! I would appreciate it greatly. Thanks in advance.

Sincerely,
EZ

Cheaper to buy a replacement motor than fix a transmission. The gasket set is $200 plus you should buy OEM head gaskets another $75..plus all the labor of splitting the cases Vs just pulling and replacing the engine. Of course you are buying a used engine, so there are risks there too. Not a hard job but tedious..taking lots of pics as you go to you know how to put it back together.

The 4th to 5th gear issue that I know of was on 1500's not 1100's..which was fixed in 97 by Honda going to the Valkyrie transmission.

Was a heal toe shifter used on your bike..a source of trashing trannies..too much pressure on the heal shifts.
HAD LOTS OF GOLDWING 75-83
NOW INTO 1500'S..RIDING A 1998 SE

FAIR WINDS,

This does not sound like a transmission issue. Possibly a clutch issue, combined with an adjustment and tuning issue. Really, there is much that could be going on here, but the transmission would be my last suspect.

Give it a tune up.
Adjust the clutch cable to spec.
Make sure the shifter lever does not contact anything through it's travel.

That would be a good start.

Guys,

Thanks for the tips and advice.

RBGERSON - I do not have a heel/toe shifter. Just the original toe shifter is all I have. But I understand what you mean - too much pressure on the heel shifting. It makes sense.

jeffcosmo - I will try to do what you mentioned here, but I am not well-versed at bike mechanic work. Not yet, anyways. What do you recommend on giving it a "tune up"? I do have a manual, so I can probably find the specs on the clutch cable, but I'm just not sure what you mean with "tune up", sir. New plugs, wires, etc?

Thanks for the help and advice. It's much appreciated. I really want my bike in tip-top shape by spring, and it's a great old bike that I want to keep.

Plugs, filters, carb sync, valves, all the usual items we did before computer-controlled engines.
Fair bet the coils are weak as well. I like the Neon coil mod, it's worked well for me.

You might also want to try a modern synthetic oil, that can sometimes clear up problems like this.
