Hi fellow thumpers,
firstly if there is other threads on this topic I apologize.
i have a 2009 KTM 450 exc. I live at 5500 feet. I have a keihin carb. I currently have it set up with
green needle (jd kit) @ 4th from the top
in setting it up for some desert riding I plan on doing next month (LAB2V). Right now I’m getting a bog if I rack the throttle a few times. I’m reading this is semi normal as the accelerator pump has a hard time refilling.
i have put a new diaphragm, spring, lean jet is at #40 and air fuel acre 1 and 1/8 out.
im planning on going back to 172 main, red needle 5th from the top and #45 pilot.
i normally ride the trails around lake arrowhead and Big bear in California. The trails are single track from 5000-10000 feet.
Anyone see any issues with either set up?
how about the big if I get on it a few time ( not really noticeable when riding)
sorry for the questions. This is my first carb I’ve ever worked on.
Thanks in advance
