zx7r problems when running... Carb Icing??

[WINJA]

Carb icing is pretty rare,and not related to ambient temps,at least not in a temperate climate.If it died with absolutly no power at the dash,then you have a wiring fault from battery to ign switch - it's not getting that far,so trace back until you find where it is/isn't.

MOST LIKELY

MOST LIKELY

Oh yeah it is. My GPX600 would suffer at around 3 degrees. Weirdly it was fine below freezing. Think a lot of humidity causes it too.

Anyways, Gremlin hasn't got carb icing....he should take off the bodywork, start the motor and begin wiggling/tugging the wires, ignition switch, battery and sidestand cutoff.

So got around to having a better look at the bike on Monday afternoon...

Enjoying the pleasure of starting a full system muzzy and letting it idle too

All wires I could immediately access were tweaked, tugged and pulled. Side stand was played with. Then I moved onto the kill switch. Nothing immediate. However, took the kill switch apart, and pulled on the contacts etc. Also nothing.

But I noticed the throttle on cable was looking a half frayed. So I took it much easier into the city on Tuesday morning, not knowing how long a frayed cable lasts. Got some time early afternoon to take it to the shop. It turned out that it was more like 8/10 frayed through, so I might have been extremely lucky to find it.

Now I have to see if it makes a difference, as the problem did seem to quieten down right before I noticed the cable... so worst case, the problem might have disappeared...

Dont bet on it. Im a Electricial Engineer and have seen many intermitant faults return at the most crap time! Be cautious...

urgh... I don't want to assume that its gone... and it will be annoying if it is, as then I don't know what made it go away/come back...

Also I won't know for sure that its ever gone until I'm lucky enough to find a conclusive fault.

i think i found the problem...

somehow you've managed to buy a ZX7R

this can be easily solved by trading to a better bike...

Pull apart every connector you can find and give it a squirt with CRC, plug and unplug a few times. Maybe you'll get lucky, doesn't sound like your loosing all power from the battery as you first were. Was the loom they gave you brand new? Could it be it had an intermittant fault in before you got it?

[Gremlin]

I should have a sub forum for my problems I think....

Another one surfaced today, it felt and behaved like it needed to get flicked over to reserve, yet it didn't need to. Once revving it beyond 3-4, and more like 6-7, it was still fine. When revving it, it was almost like a rough burble (later it would of course it would be the cylinders)

Jetted into Mt Eden before a class, they reckoned crap in carbs. Getting sick and tired of constantly visiting Mt Eden I popped over to Ricky, because I really trust him. He played a bit with liquid, and found that cylinder 2 wasn't the same as the others (liquid not evaporating as fast) - and don't ask me exactly what it means... I just know it obviously isn't operating normally...

As for the jerk, I'm not 100% sure, but it might be gone... but I certainly wasn't travelling at a constant speed heading home in traffic... so more testing is needed there...

Just taking a huuuge amount of time, effort (and dollars) to get the problems fixed... its extremely annoying.

It's a lemon, sell it. I know that sounds harsh and a pain in the butt, but life is too damn short to suffer that crap.

[Gremlin]

Beginning to think that way.... but I still have to sell it...

Wouldn't sell a bike in shit condition... but I have noticed I have developed a wandering eye when seeing some gorgeous model eyeing me up

My bike had better shape up or ship out. Then again, when the problems are fixed, it should be really good. Blardy hell... whyyyy me, I don't have the money to let it sit in the shop and be fixed

Symtoms of icing?
After a run of more than 5-6km;
Rough idle on slowing down and stopping (if it doesn't die-out completly)
Rough or no running on slowing down for corner and then opening throttle - but if engine stops it starts and runs properly after 3-5 minutes of sitting.
Throttle sticking in one position.
Piss-poor fuel economy.

Needs: cool temperature AND high humidity.
