TPS for a Gen 1 1000 needed

[AyJay]

Hi everyone,


This is a long shot, but has anyone got a Throttle Position Sensor attached to a knackered set of FZS1000 Gen 1 carbs they'd be willing to sell? Mine's on the way out and a new one is hundreds.

Some suzuki ones will fit.
I have a note on what ones somewhere, just need to find it

Cheers Unfazed. Any help would be appreciated.


It would appear the xvs125, 250 and the T Max TPSs are the same too. I might have to buy a carb to get one.

It was the Suzuki RV125 Van Van 03-06 TPS, it is the same fitting, but I had to reverse two the wires to get it working on the fazer 1000 as it was working in reverse on the suzuki. It was very easy to unclip the wires to swap them around in the connector block. I did not need it afterwards as the problem was a dry rubber seal in the hole where it fits causing the tacho needle to jerk.
Out of curosity what is the problem with you one?

Ah. Thanks for that info unfazed.


I think it's plain worn out. It's done 121,000 miles and the when holding the bike on a steady throttle, throttle just open (as you would when doing 85 on the motorway) I can feel a slight hesitation. It's very slight, but just recently it has started occasionally flicking the tacho needle and pointing at 3000rpm.


I tested the TPS according to the manual and it registers 6k ohms at rest, then just slightly open 10 or 11k, then down to 5,4,3,1 which I presume is the track on the potentiometer being worn out. I could easily be proved wrong by someone who knows what they're on about. This is just my guess.


I've found a tragic looking pair of T Max carbs on flea bay for 25 quid, TPS intact, so that's good. If only he knew they had a 200 quid part attached to them!

Excuse the pun but your on the right track and yes they do wear out.
My Fazer 600 one had the same problem at around 70000 miles with the resistance varying and I bought a Suzuki one for £40 which is exactly the same and it has been fine since.

Most of the 3 wire ones like the Fazer ones are simple passive devices with just a potentiometer inside.

Amazingly enough the Suzuki part is only £80 brand new whereas the Yamaha part is £240. The only difference being the box it is in. I don't believe any cardboard box is worth £160 
Mikuni make the 600 ones and Keihin make the 1000 ones.

Let us know how you get on.

Just in case anyone needs to know, the TPS from a 2002 T Max does indeed work on the FZS1000.


Unfazed - it's a winner!
