Random Engine dying??

**Sketchy_Racer** · 11th April 2006, 19:02

Today i was on my way to piecock to see a mate, and as i was going down the straights (at about 120ish) my bike all of a sudden lost power and wouldnt run higher than 6000rpm.

Oh my bike is a KRR150ZX

After starting off again and cruising along at a slow speed it seemed to clear it self out..... and ran fine the rest of the way there and back.

Any clues?? its got me stumped

I have it!

Firstly, it's a Kawasaki. That's the main problem.
Secondly, it's a 2-stroke.

So...Get a Honda and get your strokes upgraded to four.

On a serious note. Fouled plug?

Have you replaced the sparkplug?
Mine was doing random coughing and dying while idling, and it was suggested that the bike might be running too rich. I took the old plug out, and it was covered in oily goop. So far the new plug, and only leaving the choke on for a few seconds when I start it seems to have it sorted out. But if I start having random problems again, I'll fiddle the air/fuel mixture.
Good luck getting it sorted.

Whip the plug out and sandpaper it clean and see if it works. If it does work, it's only a temporary fix and you'll need to replace the plug

Sounds like a typical kawasaki. Follow cowpoo's honda burning guide

Fuel blockage? Have you had the tank off and maybe one of the vent hoses etc isnt correctly routed?

Sounds like a temporary blockage of some kind. Fuel,, or carbon blocking a power valve maybe? Is your motor running clean enough on the inside, (ie. power valves not gumming up)? These things happen occasionally, if it keeps happening, then have a good look for the problem.

SNAP!!

i got it.

I got my mates infared heat gun and after a good ole thrashing it was only reading 53degrees on the head and 55 on the hotest part of the radiator.

Now the temp guage.

I didnt think it worked until now. At the lights if sitting for like 10min, the temp guage gets to about 1/5 of the way up. at 50kph it falls back down to in the 'blue' bit in the guage. At 100kph it goes all the way down below the blue.

SO, i figured it out to be that becuase it has no thermostat it cools it down too good for the low temp in NZ compared to where ever it was made for.

So, I blanked off 1/3 of the radiator and so be it, it runs perfectly. with the temp guage at 1/4 !!

doesnt foul up and runs mint YAY

thanks for all the in put tho guys

That's useful to know.

The temperature gauge on mine never reads anything unless I'm riding around in first for any length of time.
I think the KRR's are made in Thailand, so that would explain the need for a kick-ass cooling system.

**sefer** · 12th April 2006, 11:27

I've only seen my temp gauge move once since I've had the bike, pretty normal for a krr though. They haven't got a theromostat at all, so nothing to regulate the temp.

I might do what you've done and make a peice of plate up to block out some of the radiator, since bogging out and (sometimes) stalling is a right pain, expecially with a kick-start.

Yeah, think I need to do that to my RG. It takes a while for it to warm up
