Hi <o> </o> I feel my 950 could run better than it does, at present the jetting is standard with the clip moved to the third groove, a Sommer copy door and Akrapovic cans with the standard restrictors. <o> </o> I find during my daily commute through town that the engine runs rough below 3500 rpm, it sounds as though itâs running on a little choke. So I thought Iâd try a different approach as I know little about jetting and have a lathe in my workshop. <o> </o> I made some different restrictor as seen in the picture. The smaller bore is the same as the restrictor, this enlarges to the full bore to give a smooth path for the escaping gases. <o> </o> This made changes to the way the bike ran and sounded. The first thing is the noise which is louder than I like. Around town the bike is a dream now (other than the noise) running smooth and clean and no snatching from closed to open throttle. On the open road things are not as good, opening the throttle wide at about 4000 rpm the engine feels down on power until 6000 rpm when there is a definite surge in power back to normal levels. Vibration from 4 to 6000 could be greater than normal. <o> </o> Now I donât know if this info is of interest to anybody but thought Iâd pass it on. P.S. How do I insert an image held on my HD?
