2T snowmobile gauges?? Anyone thought of that?

#1 Post by Disco » Tue Sep 27, 2016 5:32 pm

Hi all,

Just bored and reading more threads on here, thinking future thoughts of what to do (or not) based on some of your great ideas and photos. Since I'm from a northern state and love snowmobiles, I had an idea that some of you may have tried, would like to try, or know more about. A snowmobile gauge pod. The speedometer would perhaps be the biggest issue because of how it is set up, but maybe not? The tach should work with no issues (some of you are fighting the 4-stroke/2 stroke issue with more modern tachs).

Here's an example I found on a very quick search.

Here's another, from an old ss 440. If cleaned up this could look great on a naked bike. Has anyone attempted this? What might be major reasons why it wouldn' t work?

The issue with the modern gauges is working out what the inputs are and you always have to find one which doesnt use an external ECU really, thats why people struggle with the dash's post 01 really.

Which is perhaps why some of the older snowmobile gauges, such as the 2nd one shown might be a great option. Computers weren't a factor, yet the gauge pods are easy to find and fairly cheap, some would look great on a naked bike.

If I ever take the fairing off my Spec II, I might mess with the idea. I know where there are two yamaha srx 440's sitting in the weeds, but cosmetically in good shape.

Jon, you don't need the challenge of trying to find sled parts down there. :smt002

I'd have to learn a bit more about how the speedo is set up, I've never really had to mess with one. I know on older snowmobiles it's just a normal speedo cable that comes out of the drive shaft or on some, the primary clutch. What I'm not sure of is if/how there is some sort of gearing either in the speedo output off of the driveshaft, or within the speedo its self to make it function somewhat accurately. Probably the easiest thing would be to spin one with a drill at full speed and do the same with a bike and compare results, or simply do a temporary hook up to the cable on a bike and see what the results are.

Anyway, it's food for thought, and around here, finding an otherwise junk sled that has cool/interesting gauges isn't too difficult. most snowmobiles have a life of less than 7,000 miles, so components like speedos have plenty of life in them.

Interesting,
I just pulled a part number for the speedo gear for an european rd350 (it popped up first) and also stumbled on the speedo gear for most yamaha snowmobiles (also first one I found).

Bike - 4L0 - 25190-10
Sled - 1FK - 25190-02

A possible match? Granted these are totally different years and I took 2 seconds to look for a part number.
Hmm... Maybe the snowmobile world would have some parts that could work for all of us, cheaper and more available, be it replacement, restoration, or modification???

no totally different, the middle number just means 'speedo gear' in this instance, the first part is the bike it started with/on, the last part is the revision.

Right, but these were two very fast look-ups without any actual attention paid when doing it, just the first two I found. Maybe there are some out there that are the same part number minus the vehicle ID. Additionally, would the different part numbers on the speedo gear mean that the speedo gear on our rz's wouldn't work with the speedo/odo from a snowmobile?

I realize they could be WAY off, but then again, maybe it's only a livable percentage or pretty close to spot on.

Anyway, just thinking outside the box to the possibility of interchangeable parts.

The speedo drive gear is on the wheel on the bike, you cant really make a bike version run that much faster or slower as its wheel dependant and the unit is usually driven by a cable or electrical. Where it is driven from on the snowmobile? and how to the systems differ?

Not trying to rain on your parade at all just trying to help. The mechanical snowmobile unit had something like a 12mph speedo, thats not going to work on a bike, hence why i suggested a substitution which fixes the problem in one foul swoop etc.

29L-25168-00-8L
5KS-25168-10-35

First # is an RZ350 front wheel, 2nd is from a V-star 1300. Despite the middle 5 digits being the same the only similarity is that they are both round.
Typically if they use a part on 2 different vehicles the part # stays with the first model to use it, hence the US RZ350 wheel listed above is actual from a 29L model, '83 RZ250 that was never sold in the US. Similarly some RZ parts now have Banshee model codes because they are interchangeable but updated for the Banshee so not identical, hence going to the new #. I know what you are thinking, but since bikes and sleds pick up the speed differently its a real long shot, although not entirely impossible.

Exactly Ruz.

Electrical bike speedos pick up from the gearbox with a sensor or wheels if they use a magnet, if its a magnet system that drives the snowy then youre still stuck with the single revolution issue, and the circumference of the wheel/tyre x the revolutions = the speed....
