Running rough

[raptor4lady]

I am getting a backfire right off idle. It will only run at idle. Fires right up but cant give it any gas. Does this sound like a valve adjustment? I have a video of it running.

Have you played with your air/ fuel mix screw at all? Try turning it all the way in and go 2 full turns back out and see if it makes any difference.

 

[raptor4lady]

Yes I have. It makes no difference when I adjust it.

What jets are you running and where is you needle at? Post the vid of it running and your trying to gas it.

 

[raptor4lady]

How do you post a video? I have an MP4 file

Take the carb off and clean it good pull the jets and clean them too.. Is your petcock flowing enough gas?

 

[jeffsyfm350x]

Will it rev with the choke on? If its not the carb Id say it jumped time...!

No it wont rev at all. I already took the carb off and cleaned it.

How do you adjust the timing?

Is this good gas flow?

 

[american opel]

yes that's plenty.does it do it if you have the airbox and filter on?are you sure the choke is open?

 

[lbjamm]

To me it sounds lean like maybe a air keak in the boot or not rich enough jets. JMO

Yeah but he should still be able to open throttle with it out it dying I dont think its a carb prob..

 

[raptor4lady]

How do you check the timing?

 

[raptor4lady]

How do you post photos?

 

[nukacola]

upload photos to imgur.com or photubucket.com to host them, then use the insert image tag in your post with the URL they give you.

Which one is better?

If I were you, I would check my connections going from clutch/pb lever and unplug them and try it. I had this problem your talking about and was ready to pull my hair out, and it was those danged clutch and pb safety switches that were keeping my bike from revving up. I would almost guarantee its those. It takes about 5 seconds to unplug the one and switch plugs on the other, and it will run fine! (We hope) haha
