Problems with the wee Spada

[Brayden]

Like none other huh, maybe we can open tourist resort there!

Little update on the bike Today it has been bogging down lower down the rev range since it first started at 9, was at 5-6 today. On the way to my night shift holding down the throttle all the way in 2nd travelling 60/70ish k's it suddenly revd all the way up to 13k with no issues, ran fine all the way to work. Didn't hear any loud bang from the exhaust or anything, maybe some built up shit in a pipe somewhere finally came loose?

On a related note, I forgot to mention that about a week ago my speedo rev counter only was half working, only lighting up half the revs. I also noticed after my revs started to work that the speedo was now fully lit? Maybe this could have something to do with electrical or something..? Will be cleaning the petrol cock on Friday regardless.

Cheers for the replies!

Stranger things have happened at sea, but...
A lighting issue is VERY unlikely to have anything to do with a failure to rev freely. The 2 functions (lights/spark) are on unrelated circuits.
Holding the throttle wide open, and the engine suddenly responding as it should, suggests that the vacuum effect of an open throttle has finally sucked a hose blockage clear. Or dragged a drop of water through one of the main jets. Perhaps you will never know...

Yes and no - a dodgy earth return path can affect the ignition module which is where the tach will pick up its signal from. Lighting to the instruments is wierd though.

If you are about over xmas yo are welcome to stutter up to Kapiti and we can take a squizz.....

He wasn't clear, but I understood him to mean the dials didn't light up properly. If the tach needle was reading less than actual revs, I'd agree with you. Speedo is hub/cable driven on Spadas.

Ah - I wonder if there is a loose connector some place?

Cheers mate, everything working as it should now, but if it happens again I'd definitely take you up on that offer!

Yeah lighting on the bike is kind of strange I think somethin is a built faulty. My Speedo light has not been working for the past few months as well, makes it hard to keep to the speed limit sometimes as I have to guess me speed

Clean the petcock, clean the filter (it's on the petcock, in the arse of the tank)
Clean the carbs and clean/replace the vac line to your petcock (lots of cock being mentioned here...)

Hopefully it was a petcock isuue and is resolved, they're troublesome piles of shit those petcocks.


Cock.

Spadas are typical of those bikes with a shell-backed headlight. There is a spaghetti of wiring and connectors in there, and shorts/bad connections are common.
The other thing they have is a bright little bulb at the bottom of the speedo face which lights up when the road speed exceeds 90kph.

Not after I've been near one....

BTW, it's not a hard job. Remove tank, drain fuel, turn tank upside down on a soft surface (no need to scratch that paint), remove petcock (the bit that you use to go from the main to reserve tank), disassemble (noting the position of everything), clean the mesh gently, check for any blockages, reassemble, put it back on the tank, tank back on bike, connect fuel line, refill tank and ride.

If you haven't done so check that the fuel line isn't crimped anywhere.

I'd add to that check if it has an inline fuel filter anywhere, and replace it.

my though was fuel tank vent or fuel issue too.
