I'm getting some popping coming from one of the carbs I think the one in the front. Is this something to take back to the dealer to look at or is it normal?

 

What mods do you have done to your KFX 700?

 

backfiring out the carbs is a lean condition, out the muffler is rich.

rejet.

 

no mods its stock except pink spring and front bumper thanks to a tree [img]i/expressions/face-icon-small-smile.gif[/img]

I checked the plugs and they were on the black side, If I need to rejet what should I rejet to and what is it jetted now stock?

thanks again

 

Stock jetting is 135f/140r,check to see if there is any air leaks or leaking gas around the carbs.Also check the bolts on your headers to make sure there not loose.Are you using the right GAS 91+per manual?Is your air filter been cleaned lately?[img]i/expressions/face-icon-small-confused.gif[/img]
