messing with my bike once again, i noticed that the front cylinder does no get hot while running, exhaust stays cool. also when trying to throttle up it only revs to 3000. any advise? should i swap injectors? compression test? please help! |

Whoa first of all are you getting a spark and is the front plug wire hooked up correct? Usually the simple problem is it. |

Probably a fouled plug or a loose/damaged plug wire. |

just replaced the coil because resistence was incorrect, along with new plugs and wires.problem still exists. |

another forum member had a similar problem recently on an x1, turns out it was the cam sensor. |

i saw that, but is the x1 carb or efi? i will look at that though, thanks. |

2000 and newer X1's are EFI |

1999 and newer.. All X1's were EFI |

Take the plugs out and check for spark on both cylinders. And depending on what happens switch plug wires on coil and try again. Are the wires going to the coil on the proper terminals? Also you said you were messing with your bike again so the question remains (what were you messing with).

My apologies Bluzm2 I always thought the 99' X1's were carbed, now I know. |

"messing" meaning trying to diagnose the issue. ive already tested for spark, also already check coil and wiress, everything is good there. also performed compression test, both cylinders are above 120 psi. following the service manual it ends up being the cam sensor, will let you know if that works. |

Check the cam sensor wires before you buy a new sensor, especially where they pass through the case and any connectors.
Possible fuel problem ?
check injector wires around the connectors, you could also swap the injectors over to see if it does the same on the rear cylinder.
does it throw any trouble codes ?
have you got ecmspy and cable, if not get it and read the tunning guide at(www.ecmspy.com). |

This is the same prob i'm having with my 00 X1, have checked every thing possible,
every thing checks out ok.(semi ok really other wise it'd be running).
Has good spark,fuel,plugs,leads etc....
It just doesn't go together
I have just tried a new to me ECU no difference.
Had it on a flash new tester the local auto sparkies got and its showing that the front cyl is firing before the injectors pulsing?.the rear is OK,fuel then fire..
I'm waiting for a new Cam sensor to try that.It has to be it,nothing else controls firing bar ECU?????????.
Hopefully i'll have tomorrow or the next day?.

checked all wires from the cam sensor to the ecm. all is good checked voltage to cam sensor, book says it should range between 0 and 5 voltswhile cranking. but voltage only went to about 2 volts. is that means to replace the sensor? rotor cup is tight. as for the injector, if i got by the book the next step would be swaping the injectors. but i think the the sensor should have ranged between 0 and 5 volts not 0 and 2.
nallac please let me know if the sensor works out for you. if it does i will probably follow your method. |

Well still waiting for the cam sensor,hopefully tomorrow(fingers crossed).
I never checked voltage from the sensor,
the Auto sparkies checked that it was pulsing/sparking,its getting a hell spark, (i knew that when the coil gave me a goooood zap).Tested good via there plug tester,sparked to the maximum width there guage went to.
I tried swapping injectors too,to no avail,still have em swapped.
Will let you know how i get on Jesse.
What gets me,is if the cam sensor is on the way out why does the rear cylinder seem fine?.
I'd thought that it would make both cylinders run like crap?.
Unless it has seperate timing pulses for front and rear?,like two sensors in one.. |

good question, you'd think it would throw timing off for both. i don't really know. but the fact that i can see pre detonation from out of the intake let's me know I've got fuel going to the front. |

still waiting for the cam sensor........
Measured mine last night,1.9 volts,Down on the 2-3 recomended in the manual.
looking at the Manual the CPS has 3 wires,
one must be power in and two out,
the two out tie in with the TPS sensor wiring.(which checks out OK)
So it has to pulse twice,once for the front,once for the rear. |

I had a similar problem with my 99 S3. Turns out that the wire that runs to the injector came out of the crimped on connector that is inside the boot and clip inside the connector on top of the injector. It was impossible to figure without an ohm meter and following wires according to the diagnostic procedure in the service manual. I do not recall the procedure exactly right now, but there was electrical pulse to that wire when cranking the engine over until I got right to the injector. It was fairly easy to fix by exposing that wire and soldering the wire back into the crimped brass terminal. |

The good new...Finally got the new CPS in,
The Bad news...it didn't fix the problem
it did start and run on two cyls till it fouled the front plug.
What next????????.
i have checked everything(i think?) twice,
the coil resistance test between plugs is quite high.Its sparking but is it late?. |
Cellerjc
| | Posted on Saturday, September 11, 2010 - 03:52 pm: |

did you check the rotor cup to see if its loose? I'm almost certain the CPS is my problem. the only other thing i haven't checked is injectors on mine. |

Yip checked the cup,its tight,and looks brand new.
Its got me stumped.
Everything seems to work but not together?. |

I wonder may be your timing map(s) somehow got corrupted. Front and rear should be the same. |

Kalali,i have checked the mapping,they are the same. I have loaded my stock maps on as well and tried them still no go.
reloaded race maps again and its still running as a single banger..... |

Stopped in at a local Kawka/suzuki dealer today to pick up some new plugs,had a chat to him.He asked if i had checked fuel pressure..i haven't, will have to check that along with another compression/leak down test. |

i think im going to check injectors and harnesses before spending the money on a sensor. at least that way i know if checked everything. |

If I remember reading correctly, you had mentioned that the spark comes before the injector pulse in the front cylinder. Now at the risk of stating the obvious, have you triple checked that the front and rear leads are not accidentally crossed neither at the coil nor going to the plugs? If not, and just for the sake of experimentation, I would switch the leads going into the plugs and see what happens... |
Cellerjc

the spark wires are only long enough to reach from coil to plug on each side, unless your saying to just swap front wire with rear wire. but i dont see how that would make a difference. unless your talking to nallac, i dont know what the configuration on an X1 is but i have an XB12R. |
