first i put the honda rec. jetting in and it was way to rich with the stock pipe. so now i have a 143 main i think went back to the stock neddle but raised the clip one changed the pilot richer and did the leek jet. dubach racing says go stock 04 250r jetting what ever that is.

I am running a 155 main, JD red needle(4th groove i think), and 42 pilot jet. I have a R muffler with the stock head pipe(the longer X head pipe keeps the low end power). I also have the backfire screen out, the air box cut, and the pink wire mod. I have a Dr D ordered so I will know in a week or two how the jetting is. I would be surprised if I have to make much jetting changes going from the r muffler to the Dr D. If anyone is interested in a complete R exhaust let me know.
