How many of you have had the hesitation problem? : KawiForums.com Kawasaki Forums: Kawasaki motorcycle forums

Yup, Thats right, I have it.

Done some searching and have found a couple of different possibilities. So my question to those of you who have experienced it in the past or know someone who has...

A brief description of your particular problem and the the solution if not listed in the poll.

Mine hesitates/stumbles, and kind of falls on its nuts at around 10.5-12k somewhere. It will pass it and go higher in the rpms. Hard throttle= tiny hesitation. Moderate to low throttle= hard stumbling hestiation.

I personally have replaced plugs, air filter, and oil. Kickstand is already bypassed, but I need to check the jumper still. It was already bypassed when I traded for the bike. I purchased 2 used pressure sensors from ebay for 10 bucks each, haven't installed yet, just got them yesterday. Going to check the Fuel pump out this weekend and most likely replace anyway ( Just seems way to common for these to go bad, from what I have read).

If these don't solve my issue I will be building a leak down tester, lol. The reason I will be building and not buying is, I looked around for one and they just are to expensive, almost 200 bucks for a couple of pieces of air hose a regulator and threaded ends? I think not.

If I get no joy there, I'll be cracking her open.

ETA: The other day I was cruising home form work on the bike, and was coming up on a red light at about 55mph, in 6th gear. It was pretty far away, so I pull in the clutch and kick down to neutral and let the clutch out, as I have done a millions times in the past ( Not on this bike as I have only had it for about 3 or 4 weeks).
I know this can sometimes be a very hard clunky thing. Anyway the bike shut off, I didn't even realize it. So I'm thinking with the hard clunking of the downshift, may have unsettled my kickstand switch, and shut her down. Just a thought. I will vote when my problem is solved, hopefully this weekend, maybe not if I have to buy parts, cuz I'm broke.

Kickstand, lol. Wasn't bypassed, the piece that connects the switch to the stand was just removed. Shaking the switch I could hear something rattling around. The hiccup is gone.

Wrong, i wanted it to work but it didn't. Fuel filter has metal shavings, gonna replace the pump, I knew that was the answer just didn't want to spend the money.

Just take the fuel pump screen/filter out and clean it thoroughly, before you purchase another

03-04 Fuel Pump Replacement. ***Warning: Lots of Pictures***

**WhoUtink** · 12-29-2012, 03:21 PM

I cleaned the crap out of it. I sprayed carb cleaner through it, then blew it out with compressed air, then filled and flushed with fresh fuel and blew it out with air, several times. No Joy.

StuntbikeJake- How is that pump working out so far? thats the first thing I was thinking when I pulled it, was the fact that it looks no different than so many fuel pumps I've seen in the past. lol, give me the go ahead and I'll do it.

Me and my teammate are both running civic pumps in our bikes. No issues at all. Even the fuel pressures are the same between the stock mitsubishi pump and the honda civic pump.
