The horrible word again - TPS problems - Fazer 600 year 2000

[darrsi]

I just bought a fazer 600 v reg and it didn't have a tps just a smashed casing, found 1 on bike hut for £38!!!! fitted yesterday and guessed how to set it, runs ok I think, shame my carbs are dripping coolant

Oh bugger, that's probably the one they offered me by email, the only one i could find

...runs ok I think, shame my carbs are dripping coolant

Now that's an accomplishment

Tighten all the clips around the thermostat housing underneath the front part of the fuel tank, and top it up with coolant while your there!

I just checked and bikehut have another TPS for sale.
The thermostat on my bike doesnt appear to be the correct one as thew wiring pins dont go anywhere, square male pin and round female  , so mine might be overheating?? going to try to redirect the water pipes away from the carbs to stop leak.

Okay cheers.


Best to keep your leaking issue to your other post otherwise it's gonna get confusing

Took the bike out for a long run to get the engine up to maximum temperature, and as it was also very windy i thought it may also help if there was any condensation in the loom or wiring.
Kept my eye on the rev counter as much as possible and as far as i could tell i never saw it misbehave once.
'Marvellous' i thought, problem sorted!
 
Then, on the way to work this morning, the rev needle dropped to 0rpm about 12 times, then back up to normal speed again.
It doesn't go to 3000rpm at all, which would indicate TPS problems.
And if i unplug the TPS then plug it back in, it goes straight to 5000rpm, also indicating no TPS issues.
 
My head hurts now, has anyone got any other ideas at all what could be going on?

Anything else electrical stop at the same time? Headlights would be the main thing I'm thinking of, that and warning lights (wouldn't be the speedo I don't think as that's mechanically driven.

Speedo is still electrical, hence wires, not cogs.
I've ordered a used TPS for starters, got home last night and bike was running slightly jerky at lower revs, and when i did a diagnostic check it went to 10k again, even though i set it to 5k a few days ago.
And just to rub my nose in it, the needle has dropped clockwise again so that it's underneath the stop pin.
Must remember to turn the engine on, rather than switch ignition off when it's at the 10k position!

is it actually affecting your ride? If not.... ignore it? Put on a acoustic tacho?

Yeah it did today, the bike was very jittery to and from work.
I've just sorted the needle in the clock out and reset the TPS to 5k again so hopefully it should ride a little better.
There's no way i could ignore the rev counter needle bouncing all over the place, that would send me mental.
I'll get the other TPS i ordered within a couple of days and give that a go.

UPDATE: I think the new TPS has done the job 


After fitting it, i set it to 5k then twisted the throttle, and it went to 10k then back down to 5k on release, which i believe is the way things should happen.


With my old TPS yesterday when i twisted the throttle it went from 10k to 5k to 0..........not correct.


Also i could feel the difference straight away just riding out of my driveway, and after a short ride up the road the needle behaved and the bike generally felt much more at ease with itself. 




NOTE: My TPS hadn't failed completely but was obviously on it's way out.


I think it's important for people to know it did affect the general riding of the bike, especially at lower speeds and revs.
I was getting a jittery/hesitation feeling, almost like i was riding with the brakes on, but at higher speeds it wasn't so noticeable.


Also for what it's worth my original TPS had 'A2' stamped on the back but the replacement one has 'A1' on the back, but it works okay.

Temperature senders on on the fox eye are dual connectors and they are not interchangable with the box eyes single connector type.
