Thanks for all the info! Having tested now I am unsure as to what the culprit of my dropping idle and hesitation is.
The ignition pickup tested at 320ohms so all good there.
Following all the instructions the ohms test was 4.8k cold and warm.
The volts is 0.68 with the throttle closed (which is higher then the max 0.5v you specified) and then runs smoothly up to 3.9v without and huge jumps or losses on the way to full throttle and back to closed.
Does the 0.68v mean the sensor needs attention or would this not cause the issue? As spiking isn’t happening and so I’m inclined to think my issue may be elsewhere?
Thanks for the reply, gremlins like this aren’t major but makes riding the bike less enjoyable when it isn’t quite how it should be!
Hi Hubb.
Gremlins can be hard to locate.
If you're convinced you've electrical Gremlins, which it sounds like you have, I'd be working my way thru all the electrics & test everything to manual specs.
2 main loom multi-plugs under left front infill panel, known Gremlin location for corrosion, I found some green corrosion in em on mine when I was unpicking the loom yrs ago to get rid of a shitty Meta alarm system, so I thought fuck it, while bikes stripped & half of loom is out anyway, I started at the arse end & methodically opened up every loom connector, pulled every wire out 1 at a time, wire brushed out any green crap, flushed with brake cleaner, painted every connection with AC50, never had any electrical issue since, that was nearly 10yrs ago.
Out of curiosity, have you replaced or had the plugs out, checked cleaned, ohms tested & gapped em etc, never assume all new plugs are good, test & gap em every time, fake dodgy plugs are out there.
Plug threads & cyl head threads should be clean & grease free, plugs earth thru cyl head, if gummed up with copper grease it can kill the ground for the plugs, many use copper grease,it's not conductive, clean is better, no car or bike motor comes out the factory with greased plugs.
Main Battery to engine earth cable terminates at starter motor bolt, unless cable Ohms test with no resistance which it won't, it's 20+ yrs old, it'll defo have some corrosion inside the copper strands or in the ring terminal crimps, copper multi-strand earth cable & ring terminals are cheap, common sense to replace it, at least then you're 100% sure you have a good ground from batter to starter, starter bolt holes need some love too, drop starter out, run a tap thru em, blow em clean, same love to bolt threads & under bolt head, it's the only earth between battery & engine, so it need to be clean & grease free for a good ground.
Let us know how you get on?
