Suggested maintenance

Postby dpmath » Thu Jun 07, 2012 12:14 pm



:?: I'm picking up a 95 Aspencade Trike on Saturday and would like suggestions on maintenance actions that should be inspected/taken. The bike has 53K miles and has been well taken care of. My problem is that I haven't ridden since the 70's so I'm unsure of what might need looking into, other than my automotive experience. A fellow PGR rider who knows Goldwings in and out did check the bike when we went to see it and said it was in great shape. Thanks to any input you have!

hello dpmath, welcome to GWD.service the drive shaft and u-joint, most trikes use the stock u-joint not a heavyduty one

Grease the drive shaft coupler and by all means REPLACE the timing belts ASAP.

As stated, check the drive system and timing belts (Probably just change them for peace of mind) then do as with any other new vehicle, change oil and oil filter, clean air filter, replace brake fluid, check cooling system and brake pads (also consider flushing brake system) and grease all pivot points and you should be good for many years to come.. You should also consider changing the fork oil and fitting stiffer springs to correct for the extra weight of the trike conversion..

This is really helpful! The kit is a 2007 Motortrike.
Thank you!

MY cheat sheet for 1500

Drain tubes on left side with oil changes. SE 1500 that there are 2 tubes/hoses inside the left engine cover that are supposed to be drained when changing the oil. Check and drain those.

New sub filters a PITA to get change the cruise and sub filters (behind the tupperware by your knees) as they just disintegrate in time not mileage.

Blow out alternator brushes compressed air nozzle

check rear pink VS blue shock air filter under the seat you can take the air pump out and change it's filter and check the descant beads if they are blue put them on a piece of tin foil in the oven at 400 degrees and watch them they will turn pink again remove immediately from the oven and put them back in the air pump. They keep water from getting into the shocks.

check/replace timing belts

vacuum lines. When I had my carbs done, the mechanic found 5 or 6 lines that had holes in them. Some have 90 degree bends molded in and they rub on adjacent parts and get holes in them, especially as they age and get brittle. The vacuum lines are like spaghetti on these things. Worth checking though.

4 DOT brake fluid

If you need to pull the starter for any reason make sure you get it all the way in by hand before tightening the bolts! Otherwise the reverse gear can break and an engine out job to fix that! Several people have done that.



1. Engines on the GL1500 proved to be the most reliable Goldwing lump during their time. They just go on forever, I know several owners with over 150,000 miles (I know there are some with double that) on their 1500's and they sound as good as new. A light rumble from the clutch area when idling (which goes away when you depress the clutch lever) is normal, I have had this on my two new 1500's as well as a seven year-old one! The engines from 1993 had needle roller bearings fitted to the rocker arms to make things even quieter. The 1990 models got improved driveability with tighter bodywork which made the bike rattle less. Gearboxes are quite reliable although the gearchange can be clunky, especially the 3rd-4th change, almost unforgivable on a machine that costs as much as a nice sized car. If the 1500 you are testing hops out of 4th gear, don't automatically assume the problem is only a dodgy selector. There were improvements in 1994. The twin carbs on early models can need balancing at as low as every 5,000 miles or you will experience a huge flat spot, later models can go 20,000 between balancing. It is worth looking down into the carburettor bodies when changing the air filter, the sliders are plastic and some corrosion from the body scratches the plastic, causing the sliders to stick. A finger of grease spread as best as you can fixes the problem for a while. The early (88-89) models had to have the carbs overhauled by Honda dealers because of flat spot & sudden surging problems.

2. Electrics are generally trouble free but get yourself a Honda shop manual because the amount of relays and wiring is huge. Woe to he who decides to replace any relays with cheapo car items, so don't say you haven't been warned! None of the alternator problems of previous Wings although the bearings can wear out which gives a peculiar wobbling sound and/or vibration when you rev the engine to around 2500rpm. If left unattended the back plate on the alternator will wear and have to be scrapped. It pays to replace the bearing early, before it starts spinning in the cover. It's a doddle to remove the alternator so no excuses for letting it fall apart. The rubber damper blocks in the engine that the alternator slots into can also wear or break up and this results in the same wobbling/vibration. Also it's worth noting that after Honda stopped producing alternators in Japan during 1996 and started having them made in China instead, the quality suffered. This is down to the inferior wiring used in the China made units and is another victory for the bean-counters at the expense of the customer. Many later GL1500 and GL1800 alternators have been know to fail suddenly, even when quite new and with low mileage. I've seen one on a new (in 2000) GL1500SE fail within a week and only 26 miles. Honda did replace the alternator under warranty, with another new Chinese unit which lasted just over a year.
Starter motors are extremely reliable compared to those fitted to all the earlier Goldwings. The 1500 starter has a lot of work to do as it operates the reverse gear as well and Honda really engineered this one well, so no criticisms here. Some electric fuel pumps have been known to give up the ghost at low mileages although these are in the minority and not confined to any particular model year. The LCD clock display on 1996-97 models can be inclined to go wrong and were replaced under warranty at the time, this of course is no use to those whose clock only ran amok a couple of years later. The jury is still out on the actual cause of the clock problem, I know of two people who had the display replaced under warranty but the new ones immediately went haywire too! Theories about the cause of the problem are still doing the rounds on the newsgroups and message boards but nothing concrete yet.

3.Steering head bearings can need re-torqueing around the 8000 mile mark but oddly enough probably only every 20000 after that. A slight wobble at low speed is usually down to an underinflated front tyre or one that has too much mileage on it (even though there may be lots of tread left). I've seen 1500's with only 2-3000 miles on front tyres that developed flat spots, this is caused by the bike not being used for a while and up on the main stand, the weight presses down on the tyre and over a period of time the tyre goes out of shape. If you feel that you have to drag the 1500 around corners instead of it going with you, the fork oil has probably turned to mush, this makes the front end sit lower, thus increasing the weight on the wheel. Progressive springs improve the 1500's front end immensely, they banish the dreaded high speed wallow when negotiating the twisties.

4. Exhausts are longer lasting than on earlier Wings and when they do go they still look good while the insides are rotting but they start to sound more raspy, some owners like the change from the usual quietness of the 1500! Eventually the joint where the tailpiece joins the silencer blows a big hole and that's your lot. When removing the dead mufflers it isn't uncommon to find the collector box rotted as well, the first unwelcome sign being the mounting pipe that the muffler bolts over having rotted off and stuck inside the muffler. Collector boxes are not cheap for the GL1500.

5. Swingarms can rot badly on very old GL1500's. They usually rot on the inner side of the legs, ie the part you can't see facing the tyre sidewalls. There is a recessed welded seam along which wet mud etc. can gather and start the dreaded tinworm. In severe cases the swingarm swells out along the rotted area and can rub against the tyre sidewall. It pays to inspect and clean the swingarm when changing the rear tyre. A coating of body sealer (the rubbery stuff for sealing underneath cars) along the inner swingarm will prolong it greatly as the paint won't break down as quickly.

Bank Angle Sensors had to be replaced on GL1500's of all variants. The recall was announced at the end of June 1995. The purpose of the sensor is to shut the engine off if the rider is unfortunate enough to drop the bike. Many of the sensors failed (leaked or dried out the fluid) and caused the engine to cut out while riding. This happened to me in May 1996 while riding my 1989 GL1500, which only had 22,000 miles on it. I was only doing about 40mph at the time, but the sudden loss of power made the Goldwing feel twice as heavy as it really was, and coasting it across a lane of cars to get to safety wasn't exactly a barrel of laughs. Honda, to their credit replaced 54,388 units (many long after the recall was made) and I know of many owners who had their Bank Angle Sensors replaced free of charge up to three years after the recall. My machine was seven years old and two years outside the recall and Honda still replaced the sensor for free.

In the final few years of GL1500 production, Internet discussion groups saw a fair number of postings from owners who complained that the build quality on the Goldwing (since 1998) was not up to the same standard as earlier GL1500's. Exhausts and engine guards that rusted at the first sniff of rain, poorly fitting rear lights, uneven gaps around the headlamp, indicators and trunk, also alternators and often their replacements giving up the ghost at low mileages were the main culprits. This might have been the first signs of old age, or perhaps more likely preparing the production line for the GL1800 saw the existing resources being stretched.

Kudos to RBGERSON for the excellent and informative post. Lot's of excellent info there.

The PDF download links don't work for me.

Wow! This is awesome info! Thanks to all who provided input. I picked up the bike in Houston yesterday and did a little familiarization ride in the neighborhood yesterday. I'll be going to a nearby school this AM to do a complete check out before hitting the road. Again, thanks to all!
