[QUOTE="dansavage, post: 1337533, member: 93169"] Doug, sounds like you have a nice opportunity on your hands. To be sure I understand, you did get the RB carb modification (with RB's pilot, main, and custom needle), but now you are using the following: Specs: (now) 152/42, CEK-5, 40:1 mix And have tried: I'm in the NW, temps are low 40's to low 50's. Tried every combo of jets from 40/150 to 45/155 and CEK,DEK -3,4,5. Leaner jets and needle settings made the bog worse. I have a 220 w/ a new 35mm carb in it, and it is jetted as follows: CEL (2nd position from top), 35 pilot, and 152 main (cold) / 150 main (warm 55+F). It took me some time to get here with mine, a lot of fine tuning, but it is on. The 152 main you are using feels a little lean for your bike. Have you done a WOT plug chop, confirmed leanness isn't a problem then worked down to the needle jet clip position? Maybe I missed this in your detailed post, if that is the case, my apologies. Also a question on your needle jet position, does 5 mean the bottom position (closest to the needle tip that is submerged into the main jet at rest)? If so, you are pouring her the gas at 2/3-3/4 throttle. I began with mine in the mid clip position and it ran like hell, had to lower it a notch to clean that up. If your running in the 5th, then that would be the next step after the main verification. Just some thoughts. [/QUOTE]
