A 1500 upgrade

Post by fcanary »



Good morning folks,
My ‘86 Interstate finally pooped the bed, (stator) so instead of trying to fix it and miss a good portion of the riding season I have decided to upgrade to a 1500. The one I have a deposit on is a ‘91 SE that looks like it is right off the showroom floor. Original owner, always in a heater garage, and the best part only 6263 original miles. A total garage queen. Aside from the timing belts which I will change, is there anything else I should be aware of? Common issues and problems that may rear their ugly heads? I anticipate many good riding years ahead for myself and The Precious Cargo. I will appreciate your thoughts and ideas.

Thanks
Frank

Sounds like an AWESOME find... But also sounds like it's spent 28 of its 29 years just sitting. Does it run?

Depending on what if any work has been done by current owner be prepared for:
1 - NASTY fuel tank, Poss fuel pump and carburetor issues. If it has been stored dry or serviced these items may be Okay :)
2 - Brake and Clutch issues. Even if they still work as advertised I'd change out the fluid right away. Same goes for oil, coolant and final drive.
3 - How old are the tires? Check date codes, replace if 5 yrs or older.

Once it runs and the safety items reviewed you will want to keep your travels local for a while, you will need to slowly build confidence in the machine. Give it a chance to present to you any other possible issues. You don't want to be too far from home if it unexpectedly quits on you.

Once any possible bugs are worked out you should have a very awesome ride!

I'll chime in here. Brakes/Tires/timing belts. Safe for the road and you.

Brakes - new pads, these do wear out from time - nothing stays good forever.
New tires - self explanatory
Fluids - brake/clutch/coolant
New fuel/air filter
Air compressor desiccant.

Get an OEM manual. Lots of stuff under the "tupperware".

Changing/flushing the clutch fluid on a 1500 very easy, easier than the 1200/1800. If you have an issue with the clutch, take the slave cylinder off, clean, new parts, put back on - lots of crud will build up in the slave cylinder over time. Only way to prevent crud build up is to flush the system every couple of years, probably has not been done in a while. I would even recommend doing this up front. This is what it looks like after a few years of neglect:


Not a doom and gloom comment, just is.

The rear brake caliper can be bled without taking the left saddlebag off, but would recommend removing the saddlebag - easier to work with it removed. Do this when you do the tires if you are installing new tires.

Taking the rear tire off requires you to turn the left muffler or jack up the swing arm. You may have trouble turning the muffler so buy two exhaust gaskets for the muffler. P/N 18392-MAM-000. I'm still working on doing this. If you jack up the swing arm, will have to swing the shock out of the way.

Good tutorial by Wingadmin on how to change/refresh the air compressor desiccant. It will need to be done and it keeps the air system water free.

You have to remove the upper shelter when you do the fuel filter. Need it removed for the air filter as well.

If you have the front body parts removed, think about changing the various little air filters. These degrade over time and are easy to do.

Use a carb cleaner fuel additive for a while. Varnish will build up in the carb passageways especially with such low miles and some 30 odd years. I have used Yamalube Ring Free Plus.

As for skeletons, it's a 30 year old hardly used bike. Lots can happen. Roll with the punches, come up with a work/maintenance game plan and all will be well. Lots of good information on this and other forums. Have a good read.

Good luck.

Ernest brings up another good point - Air filter. With all that sitting, it's possible Mr. Mouse found the intake to be a nice home. See the "Air filter Hall-of-Shame" thread. But if Mr. Mouse stayed away it should be in near-new condition. Worthy of inspection.

It sounds like the wonderful garage queen is in for about two months of dissasembly and parts replacement.

Maybe 2 months in total but I have found that you make it roadworthy doing the necessities then ride. Determine a 3 to 5 day work package, do when weather permits ( not nice riding days) then ride, repeat as necessary. You may be removing/installing body panels a lot, but you get to enjoy the bike. Too much work all at once can be a downer, especially with a new to you bike.

Thanks all. The bike is in the shop now having the carbs gone through by the current owner. I’m already looking at tires and those will be replaced very quickly. Hopefully, I’ll have it by July 7 or 8. Looking forward to it.

No one has mentioned this.
Pull the rear wheel and the final drive unit and remove the drive shaft.
Lube all the splines with the proper high moly grease.
Also lube the splines on the rear wheel itself.
There is no doubt that whatever grease was in there has dried
up over the last 30 years.

This is all great info 👍

I also just purchased a 95 GL1500 SE “garage queen” with 18,000 miles and will be performing the same maintenance before she stretches her wings.

I would recommend installing the shift brace now, before any possible damage could occur.
And replace the shifter seal at the same time.
GL1500 are known for the poorly designed shifter assembly.
I did my 97 and it has been worth the investment.
