[QUOTE="Big Daddy, post: 578395, member: 37497"] Try using the choke while driving. If the bog goes away, your to lean. I think Eric Gorr's book said to use a #1468 needle. I had this problem with my 1998 cr 125 and the needle had to be changed from a 1370 to a 1468(#16012-KS6-004) this will richen up the midrange. I still have black goo coming out of the pipe. But the bog is gone. I doubt changing the pilot jet will fix this. HP-2 oil, FMF fatty, Boyesen Rad Valve, 12-51 gearing, 1468 4th clip is what I have. Good Luck :yeehaw: [/QUOTE]
