I put on an EMGO short bottle silencer and rejetted to a 126 main and 22 pilot. Here is what is happening. The bike seems to run fine but the plug is black not the brownish color im looking for. Also when I come to a stop the bike seems to idle high. Any thoughts on this would be appreciated
That seems Way too rich to me on both Pilot & Main (Stock is 15 & 110).
I've opened up my '08 AVL with a K&N air filter right on the carb & a wide open exhaust & all the emissions stuff removed & I've found (with a LOT of experimenting) that the 15 Pilot is fine & all I needed to do was experiment with needle height. My Main Jet is also still stock at 110. I'm not concerned yet with the Main Jet because I'm still on break-in.
I tried my 17.5 Pilot Jet once & it was WAY too rich & wouldn't kick start or idle right for sh*t. I put the 15 back, lowered the needle 0.002" from what it was before & it was perfect. It took a long time to find "perfect".
My Mixture Screw is right around 1 1/4 turns out & it idles like a thumping watch, never dies at stop signs & doesn't pop downshifting. Also doesn't surge just cruising under no load in 4th at 35 or 40.
