Another sucessful 22 mod
Well, maybe only .11 cents. I only used one washer to see how it would work before going to 2.
I did this in concert with a new Lexx exhaust can with the quiet core. The bike really woke up after this! Wow! Much more response instead of the rubber-band feel to the power delivery.
So, did the following on a 2012 California model:
Drilled and pulled aluminum plug covering fuel-mixture screw (discovered it was at 1 3/4 turns from factory). Turned all the way in and then out 2 1/4 turns.
Pulled needle from top of carb (diaphragm was easy to pull and re-seat, probably due to being so new)
Shimmed with 1 #4 stainless washer under head of needle. Reassembled in reverse order.
Drilled out the single hole on bottom of slide. 7/64 drill bit.
Installed exhaust can and fired it up.
No airbox mods at this time. Everything else is stock.
It started with no choke! Smooth power all the way through. No flat spots that I can tell and pulls quite well when ridden.
If you are on the fence about this mod, just do it. It is a cheap way to get a little more zing. I would say the mod just lets is respond smoother and quicker. Well worth the effort.
