Trottle body STPS motor

[Idh]

Another update!
All in bits and no loose magnets.
Bugger!!

Next plan is to throw the bike in the skip....

Well at least that eliminates one suspect.  Im pretty sure the STVA motor only drives the shaft at #3-#4 throttle bodies, and relies on the linkage to #1-#2 for them all to work, so with your missing spring and screw, it may have tried to, but as the secondaries open reverse to the primaries, nothing happens.

But you did mention you saw none of the secondaries move.  Also pretty sure the stva motor gets 5v from the loom, so best to check that too.

No, secondaries never moved. Got a genuine spring coming, so once in place I will temp fit bogy and tank back on the bike to see what does and doesn't move.
In the mean time will give everything a check and clean.

Excellent post mate! Would you recommend the spring that is listed when clicking the as the OEM counter part or some different size?

[Barbastro K6]

would need a sample to place order or else diameter of the base where it rests and the length.
It is probably a size that is widely shared by other models

I have got two new springs!

Due to my old fingers,  I have pinged them both accross the garage!

I surrender!

More ordered, but away at sea for a month tomorrow,  so my nc500 trip for when I get back is on hold.

Silly boy!

It's so easy to do though.

Happened to me as well mate. The scary thing is that a couple of days later, I found a random spring in the garage which wasn't even the one I had lost...
