Stepper motor probably

[Tinker]

So got my tank leak sorted and a fuel gauge fitted, new fork seals fitted. Worked ok for Dave Day run and now it's revving to 3k rpm tickover, it's ok when under power.. So I'm guessing stepper motor so need to get Guzzidiag out and have a play.

the stepper motor is a small solenoid type plunger valve in a cylinder, it has a 5v feed check its getting a supply , you could pull it off very easy and try some WD 40 in the intake, plug it into the feed and switch on the ignition you will feel it vibrate as the plunger moves, you can pull them apart and replace the plunger, I have a spare ready to fix mine when it goes.
have a look online , I can not remember all the ins and outs now as it was a while a go. I will dig my spare out and take a pic.
keep persevering I know you have had your share of woes, these are terrific machines once sorted are reliable, mine has not been used for 20months and she fired up, and ran ok after some intial roughness.

best of luck

Thanks how does the motor split from the body? I did look online but every comment suggested it couldn’t be split(but I haven’t looked myself)

Took the stepper off and cleaned it the pic is the gunge that came out.
The video is a rough test rig I used to try it. Sorry video doesn’t seem to work.

Hello Tinker,

do you have any news about this? Just curious, if cleaning helped or not.

Hi
good work , looks like a load of carbon does it vibrate, ie move in the housing.
I am trying to find the info on pulling them apart, see photo of the plunger and part no/
