Bad Idle and won't stay on (but turn on...)

[TomInPA]

thank u tom
tomorrow I will check now I 'm too drunk

Hey, send some of the good stuff here!

Another thought that might be easier is to clean the ignition switch. Get some good contact cleaner and spray upwards through the weep hole in the bottom of the ignition switch. This has been a common cause of no start in Gen I bikes https://www.fjrforum.com/forum//index.php/topic/125465-intermittent-code-19-on-05/?do=findComment&comment=695657

I have found corrosion of 2 pin in the large white connector under the tank near the cooling pipe....

 

[lele]

update:

I clean the corrosion on the pins...

the problem still persist

Here is a video of the problem, if someone is interested maybe can be helpful

ciao

That is a serious miss. The engine starts but clearly is missing at least one cylinder. Have you pulled the plugs? This makes the ignition coil suspect.

 

[lele]

do u think one cylinder is not fired?

go to try each plugs if they spark

 

[Mihalis fjr]

May that help..

I am kidding!Sorry for your problem!Perhaps a defective TPS but i am not sure..I have never seen a like this...

Yikes ...... horrible.

It sounds like the cam chain has slipped a tooth on the cams.

 

[lele]

how is possible the cam chain slipped a tooth??

CCT is new

 

[Mihalis fjr]

Have you replaced the CCT?Did it your self?You didn't tell it...

 

[Twigg]

Has it run correctly since the CCT was fitted? "CCT is new" is a big red flag in a situation like this.

 

[TomInPA]

Timing skip was my first thought on hearing that noise, but I didn't want to go all worst case. Not good if the CCT was replaced in between the last time the engine ran, and now.

 

[Mihalis fjr]

If the problem comes from there,not sounds that is only one tooth..Two or and three i am afraid....

 

[lele]

just opened now the head cover..everything is ok and both cams are aligned

the CCThas been changed 2 year ago, is the newer version with green dot

I repeat, before winter storage the bike was perfect run like a beast

every plug spark correclty

 

[lele]

could be a fuel pump problem???

 

[Mihalis fjr]

If your bike before storage was fine,then something has to do with the fuel,fuel lines in my opinion..But i don't know what..A bit strange...I am really curious what is going wrong there...Are you sure that the fuel is ok without water or anything else in?

The fuel pump in your video sounds normal..

I'm really curious too, I'm becoming crazy

 

[lele]

yes but it could not give the right pressure of fuel

 

[Mihalis fjr]

Have you ever replaced the TPS??

 

[lele]

TPS is trottle position sensor?

I think is fine, in DIAG mode I can check it, it range from 17 to 99 correcly
