Please don't tell me to buy a Keihin. Yes I'm sure there's many other threads but when I search on my phone it's just people saying to swap carbs and what not.

I live in SoCal and all the bike has is V-Force3 reeds. Currently has stock jetting. Thanks in advance, much appreciated!

Is your name Anthony? Did you race with CMC years back on Yamaha's?

I really haven't seen much about fixing the jetting on these, other than buying a Keihin or Lectron

Buy a JD jet kit. Worked wonders on my CR'S. Never tried the Keihin setup though.

Get an s4 nozzle, and it helps that carb out.

I remember watching you smoke every body in 250 or 450 intermediate. My dad ran the starting gate. My name is Matt Hammer, but I rode novice at the time, haha.

Haha the good ole days! I use to be able to go as fast as anyone on the track on any given day.. stopped riding for a few years and had a family. Now when I watch current pros, I can't wrap my head around the fact of me being able to go that fast lmao. Now I'm good for 2 laps hahaha.

I think the stock was s8 or s9. It's been a while, but the case reed motor we ran s4 in 03 and 04 . The later 05 to 07 was different I think. I used an s7 in 01.
