??? from another FNG

First off wanted to start by saying hi to you all and what a great board with a wealth of info here.

Question is jetting on an 05 all the free mods done YZ pipe and Lowedog kit soon on the way. Riding 90% of the time at sea level (Ocotillo Wells). It has the usual decel popping and slight backfire.

I know there are many treads on here about jetting but there are so many different setups and combinations being used I don't know the right one for me.

Thanks in advance for the help.

:cry:

cut the ais tube going from the pump to the head in half then get a two sided nut to fit tight in the hole then close and ziptie both ends, popping and backfire will be gone I swear

!

The lowedog kit is to eliminate the A.I.S. system with plugs. It is a very clean kit.

I also must add that the head pipe gets to be glowing red :cry:

glowing normal, I was saying that the popping and decel are from the ais not jetting, if you want to fix before you get the kit do what I said

The glowing is not from a very lean condition?

even after the jetting if your in the dark that thing will light the sky!

Are you suggesting not to do any jetting? or which setup should I run?

Most I see look like 170 main 48 pilot 70 starter. This sound good?

I'm not nearly that good just sharing my experiences with you, as for my self, I went for the JD kit and followed the suggestions for my area. :cry:

That should be the correct jetting for you. Also get an 04 needle and try the 4th position from the top.(05 needle is non-adjustable) Also get a zip-ty racing fuel mixture screw. With the 48 pilot you'll have to adjust the idle mixture leaner as the weather warms up.

There are 5 different part numbers for an 04 needle. Do I just use the STD one?
