Bike stuttered tonight under hard throttle......

[tim]

Coming home tonight the bike stuttered up high in the revs under hard acceleration. Filled up not long ago, but switched to reserve anyway and it did it again.

I pulled over at a servo down the road, switched to "prime" on the petrol line and shook the plugs, got back on, and I couldn't get it to do it again all the way home.

Thoughts?

It's a suzuki.....Burn it and buy a kwaka

[tim]

DOH

I need a shirt. "I posted to get technical support, and all I got were these funny smart asses"

Dodgy fuel, or you have some loose crud in your tank/carbies which is now loose crud again (instead of being 'stuck-where-it-isn't-needed-crud').

Anything in your float bowls? Drain them anyway as it also could be water in your fuel and it'll end up down there. FWIW I have had the same symptom with my old ZZR600 and it was water. Drained the float bowls, decent slosh of metho in the tank and all was good...

I'm guessing it could also be water in your ignition system somewhere, pull your plug caps off and spray WD40 up them.

Thanks Mick. I'm across the "loose crud" "water in fuel" and "water in plugs" concepts. Might consult the service manual for "float bowl draining".

So I'll spray the plugs and see if it happens again I - still 2 days of commuting to do until I'll have any more time than that. Riding sunday hope it stays away for that.

GS500......Hard acceleration....... Bwahahahahahahahahahh!!!!!!

Sorry Tim. Could've just been a bit of crap ie water or something. Maybe the Carb's need a clean out. Bring it around on Saturday. I'll be doing th oil on the tracky

[hoffy]

water in your plug leads or dodgy plug leads or ill fitted plug leads. washed your bike recently?

[tim]

Nah haven't washed it Hoffy (needs it baaaaad), but replacing those plug leads sounds like a good idea....

[tim]

Glen drained the float bowls on sat. Left carby had some water bubbles, and lots of tiny ...... Things in the fuel. Right was clean.

Right on the money Mick!

Bike is going great guns..... For a suzuki.

Thanks for your input everyone, and thanks as usual for the kellyville zx workshop expertise Glen!

Nows the time to sell & get a real bike........ while its going that is

[Glen]

No worries Tim. I've disinfected the garage just in case the Kwaka's were susceptible to Suzuki Flu

[tim]

Dammit it's doing it again - 3 weeks later..... And this time it's continuous!

dained the bowls this morning, about 5 big drops of water and i've had 2 tanks through it since then...... Maybe it's my servo! (always bp95 before anyone asks)

Kept doing it... So went to maw. Greg said sounds like you need this: motorex system guard......

So whacked a 3rd of the bottle in and rode it hard for a few ks... Still doing it maybe not as badly.

If i have slight throttle it's smooth, but there's an exact spot as you twist when it stops smooth power: jet? (carby has 3) Fuel supply?
Gha.
Tim.

I would be taking the carbs off for an overhaul, it definently does not sound electrical, talk to Colin in the workshop at MAW .... Greg is not the mechanic

[tim]

Hmm ok thanks Rob, i really shouldn't have put 15 litres in it last night

I'd wanna do as much as i can in order to learn, but depends on if the mechanic need the whole bike, and How involved and tricky is this overhauling carbs business? I'll get stuck into the workshop manual tonight.
