April 17, 201016 yr Can anyone tell me what jetting they are running on a Kehein carb at sea level for a 09 2.9Thanks in advance! The standard setup on mine was ok at 45/125, yet this was never fine tuned, yet ok, and you would need to test it as I think you might want the main at somewhere about 118-115 for it to rev out really really clean. Needle second groove from top for starters. Pilot jet seems to vary upon taste a bit to either side. I think Smage was on a 48 and some run less. Try to keep the airscrew between .5 and 1.5 turns if you can. That should give you some basics, as thest things are bit jikky and set on the taste and the day. No simple rule that I know. Due to the high vacume on the smaller 24 OKO i am running, I had to take the main down to 105 for things to clean up pretty well and could go further. Runs good though. Never realized just how rich it was running on the main till I took it to TN and tried to climb some mountains under load in the mid range consistant! Still the smoothest 2.9 I have had, and very rideable. Just my tweet on it, as most do not need a 28 to begin with! The 26 or 28 will only be less progressive and more aggressive, not less powerfull untill one gets into the top range of 80-100% throttle. Seldome done for me. All this just an update to prior posts, good luck with the things, as they are an issue within themselves. Mark Edited April 17, 201016 yr by copemech
