GL1800 Speedometer/Odometer reading

Post by ws5bj@arrl.net »



Greetings. Newbie here. Will appreciate any advice on posting here. Am learning this forum stuff at an advanced age (69). I have acquired a 2002 GL1800 Road-master Trike that I am resurrecting. Received it not running. Through the efforts of a talented friend it is now running and ride able. My issue is that in getting this bike roadworthy again, we had to replace the instrument cluster. The old cluster indicated 59,000 or so miles. The replacement from a donor bike indicates 299,000. Is there a way to get the odometer to read the actual mileage for the bike? This thing is a joy to ride. My previous wing was a 1982 GL1100 that self destructed in the mountains in New Mexico in 1997. Have not ridden since then and am loving being back in the saddle. Any help would be greatly appreciated.

I would think it should be like a car in that one of the computers generates the odometer reading and not the gauge cluster itself. My guess is that you also swapped out the computer to get it running? I would think there is no legal way to change it, unless you can find a speedometer shop to do it.

Thanks for the response. Computer is good, no need to replace. Did get the cluster off ebay, saw a video of the donor bike running on a stand, the speedo and tach were functioning properly. Figured that a speedo shop would need to be involved. Was hoping for a way to do it at home. Agree that it most probably would be prohibited for legal reasons. But can't fault me for wanting a diy.

The only reason I mentioned the mileage being stored in a computer is because I had changed a gauge cluster on a Sebring convertible to a different style, when I changed it the mileage was the same which told me the cluster was just a display. I agree on trying to DYI it, I'm the same way. Good luck with it -

Why did you have to replace the instrument cluster?

Road-master trike?? Never heard of that brand.
Do you mean a Roadsmith trike?

Speedometer and Tach would not indicate during this resurrection. We checked all of the sensors and everything pointed to the cluster. The one received from ebay worked immediately.

Take the old cluster apart and check the odometer. It is not digital so I'm sure there is a pin you pull and can move all numbered wheels by hand. It won't hurt to try.
It ain't the destination but the getting there. You are not lost until you run out of gas.

It's a digital mileage counter

You got me on the Roadmaster. It is a Roadsmith. And, upon further investigation I was mistaken about the mileage, odometer that was with the bike when I purchased it was 45,300. I would assume that this was in error. The speedo/tach gauge combo that I purchased had 259,000 and change clocked in. This tells me that the numbers are stored in the gauge cluster. I apologize for the Roadsmith error. I can attribute that mistake to not thoroughly proofreading my text.

Unless you own the interment cluster test bench that Honda uses, the answer is no. Mileage is stored in the ECU. The ECU is integrated into the printed circuit board on the back of your cluster. What was wrong with your old cluster assembly ??? Can you switch printed circuit boards ???

I do have the old gauge cluster, one of the few things that I have not tossed when I replaced it! Just dug it out of storage, will examine the circuit board. Old one did not indicate on any gauge. investigated the sensors, they all led us to believe that the problem was in the cluster. Since it is working now am moving on to the thing that stops the bike completely. Clutch is slipping when the engine warms up to running temp. I have had the slave cylinder rebuilt, now am waiting for the new master cylinder. I have a friend that enjoys, and is good at working on bikes, but he and I are not in any shape for pulling an engine. So if replacing the master cylinder does not fix it off to the mechanics in Las Cruces it goes. Unfortunately I no longer have a place to work on bikes.

The clutch is replaceable in the frame if that turns out to be the issue.

Thanks for the response. Apparently I need to do further research on the clutch replacement. I had thought that it required engine removal. No removal may make it less expensive to fix. My last bike was a 1982 GL1100, and I did all of the maintenance on it. It was less complicated than the Gl1800. 1100 lunched the oil pump while on the road, parked it in an abandoned gas station. Retrieved it the same day. At the time had no place to work on it. Moved a little later living out of my fifth wheel and could not take the bike with me. I really missed that bike. Have not owned one since 1997. Got this 2002 GL1800 recently, SO much more to this one. I am looking forward to finally getting this thing on the road. Love to ride with my wife.

A couple of things to note about the clutch system. It’s oil pressure assisted and anything that will make that oil pressure lower can cause it to slip. As Greg would advise, use only the Honda oil filter due to some others restricting oil flow too much and use the recommended oil viscosity. There is a seal in the clutch cover that can fail to seal and the system will lose clamping pressure if that occurs, but you will usually see a lot of smoke out of the bike if the seal lets go. There’s also a oil pressure regulator just for the clutch that can malfunction and cause low pressure back there. Make sure and refer to the Honda service manual for the clutch rebuild if it gets that far, there’s specifics and small details to the clutch disc orientation and order as well. Also, keep in mind this could not be clutch related, but be a delamination of the bonded driveshaft sections. It’s two pieces bonded with rubber that can let go and allow one part to spin in the other part, giving the sensation of a slipping clutch.

Thanks for the info. I have a mechanic that is available to do the clutch if it goes that far. Here is hoping for an easy fix with the master cylinder. I will keep you informed.

Are you using a synthetic oil ???

Honda oil and filter. Replaced the clutch master cylinder today, bled the system, made MANY rounds of our cul-de-sac, it never slipped. Clutch and brake levers are aftermarket bad chrome units and do not work well. Cleaning the lever and taking some sandpaper to it freed it up some. Took it to the highway with my grand daughter on the back. Ran through all the gears. Full acceleration, no slippage, clutch engages closer to the bars, as I like. Maybe, just maybe I have tamed the beast. Thanks for the help. Will try to check the odometer tomorrow. I have the old one here in the house. Just need time to get to it. Just love having all the kids and grand kids in the same neighborhood, really! To admin, thanks for this forum. I have found a fount of knowledge here and appreciate it very much.
