430 AE 84 changing gears problems or carb tuning ?

Hi Michel,
do you really use a 166 R-6 Needle jet ?
That´s very rich for this bike !

With the 6DH20 ( 3. clip position ) needle i use in my 430 max. a 166 R-0 ( by colder as 15° Celsius ) or a 166 Q-8 by warmer as 15° Celsius.
I live also in approximately 280 Meters high.
The rest is how following:

2.5 slide

6DH20 3rd clip

420 main

45 pilot jet

air screw 1,5 turns

No , mistake I use a Q6 not R6 , sorry !

'merican feet

Soo about one feet long and two feet wide?

Is an American foot as long as a Viking hand ?

Michel, I'm still working on my jetting as the bike runs rich up to 1/2 throttle, I went from a 40 pilot to a 35 and will test it this weekend. The top end seems to pull well with the 430 main, but Nikel might be right, too rich, want to get the bottom end cleaned up before I start on the main.
