need help about spark... (cam sensor)

[flower-power]

hy, can anyone help me... my c2 don't want to start... spark plugs doesn't give any spark at all... all wires are ok... is it a rectifier problem?

[kwakmad]

IF ITS A c1 or c2 check the cam senser,my c2 did the same thing and it was that senser that coused it (turned over but no spark)if it that its an easy fix and not to pricey.
heres a link with the same prob.

Strange how they stopped fitting them to the nines but fitted them to later bikes?

[flower-power]

looks like it's not so easy to find that cam sensor...

[Steve-TC1]

Do you mean secondhand cam sensor

[flower-power]

Do you mean secondhand cam sensor

i wanted to have a new one, but... the second hand sensor would be good choice as well

[Steve-TC1]

Why can't you have a new one , if that's what you want


or second hand

Yes it is ,
purely a guess but i think they thought the superior 32 bit electronics of the e/f models would do away with the need for it ,

another thing to note is all those later bikes are fuel injected as well as having better electronics , strange init

The only reason a cam sensor is fitted to an engine is to time the ignition. This is done by 2 sensors, the CkPS and CmPS (crank position and Cam position sensors) It is done so the electronics can figure out the exact position of the crank relative to the cams and then determine TDC for Cyl 1 and create the correct timing of spark.
It is more common on FI bikes and cars, as the 2 sensor system is not really required on carb fueled bikes

I've read this a few times now, and worked out it means nothing.
What you mean to say is the IC ignition unit needs the cam sensor with the crank pick up unit to comfirm when to squirt the Fuel Injection in to the right inlet at the right time. There for was removed from the zx9 E's and F's which came with updated electronics and timing disc, that only needed to generate an ignition spark.

[ckleanth]

was thinking that the only way to change the sparking to any zx9 with by using one of these
always thought that the cam sensor was for electronic/parts compatibility with other models i.e. the z1000 which has FI

basically you are both right and say the same thing

and I still dunno how torque does this

Why can't you have a new one , if that's what you want


or second hand

I gotta know how you do the parts thing m8

Maybe Kawasaki intended to fit FI to the C's but could not get it to work, and thats why its only fitted to bikes after 2000.
Wonder if a Z1000 ICU and FI could be fitted to the C's?
Would it be worth it..... probably not, zx12 one maybe.....

I dont think the z1000 ecu would be a good choice as the bike is not meant to be in the supersports category then again I dunno how well and how easy it would be to fit the z1000 injectors and throttle bodys.... what would be the gain of fitting a stock ecu if you cant remap it. maybe would be better to do this with a power commander, stick the bike to a friendly dyno and map it.
