I need advice. I have a 2006 CRF 450. It has stock jetting, boyesen quick shot, and a power now. I live in sea level altitude in PA. I have tried a 45 pilot jet to get rid of the bog. No good. Does anyone have any tips on the jetting for this altitude to see if I am in the right ball park? I am thinking of just doing the redbeard mod, or the JD jet kit. Any feed back for that? I am a senior rider so I don't need the arm jerking throttle response. I am just looking to get rid of the bog instead of the bog putting me over the handle bars. Any tips appreciated.
