Hi, I've got a '98 Scrambler 400 that I bought from a guy in the Twin Cities metro area (MN). I live in the Black Hills and there's about a 2300 ft difference in elevation and I need to make some jetting changes. It doesn't run bad but is obviously bogging a bit. I haven't yanked the carb just yet so I don't know what's in it for sure. I'd assume stock but the guy did do some clutch work and I didn't ask him about jetting. Has anyone run one around 3100 ft and if so, what jets were you running?

FYI, no other motor mods other than V-force reeds.

 

Well some scramblers came with a 230 mainjet. to rich try a 210 at those elevations. what temp? 65-80

 

Yeah, it was a chilly day so probably only 55 or so. Kinda damp too. Will try a 210 and see what happens.
