Default Getting to pilot jet screw .... popping

I get quite a bit of popping when letting off the throttle. Its not a backfire but it does make a "popping" noise. I think I need to tweak my pilot screw up a bit ... or could it possibly be normal to get this with a CT pipe, pro-flow, and open air box. The reason I am a bit confused is my KFX700 with Alien exhaust periodically backfires when letting off the throttle going down a hill and I am sure it needs a pilot screw tweak but it is much more of a violent noise than what the Raptor does. Could it possibly just be how the CT pipe handles back pressure differences or something simlar ... talking out loud here ...

I didnt do the jetting myself ... so, if the pilot does need adjusted can I get to the screws without taking out the carbs ???

It is really hard to get to the screws without removing the carbs,,,,,or burning your fingers.

I just ordered a 'Pilot Screw Adjusting Tool' from MotionPro. towards the bottom of the page It will make things way easier.

So, to clarify, if I order the tool does that then allow me to adjust it without removing the carbs or will I still likely need to remove them ???

Thanks for the help ...

I bought an equivalent tool a couple years ago. You have to be very careful that the screwdriver head is seated into the pilot jet slot or it's no help.
