    Yz250 jetting

    Next size pilot would be a 50 , which is stock . I thought with the NECJ needle you lean out pilot and main? I do notice after riding wot and pull the clutch in i do get a slight surg (lean) maybe ?

    Yz250 jetting

    Bike warmed up, 60-70* right now around 300-500ft. I can get rid of it by adjusting the air screw in more but then it's def under 1 turn out.
  3. 2011 yz250 , rb head mod, New top end and changed out my jetting for the NECJ needle and no 8 slide. I have a small bog when I whack the throttle from an idle. would changing the clip position on the needle help this? Current jetting pj 48 main 170 NECJ 3rd air screw around 1 turn

    Piston and cylinder question

    Is the wash of the piston anything to worry about ?

    Piston and cylinder question

    bike ran mint, just thought it was weird how much wash there was on the piston crown.

    Piston and cylinder question

    No didn't wash of the piston , had no carbon build up which I thought was weird.
  10. Hey guys , bought this 2011 yz250 last year looked like low hours. Gonna throw a new piston in it over winter. Looking to get some insight on how this piston looks and why there is carbon on the intake side of cylinder(shown in pic). I run 32-1 yamalube with 50/50 pump 93 and leaded 110 Sunoco. Stock jetting. Thanks

    2011 kyb sss question

    Do the upper tubes vary in size or just the lower section ?

    2011 kyb sss question

    Hey guys I got a 2011 yz250 I recently picked up. Notice the fork seals leaking. Then upon closer inspection I notice the upper fork tubes are corroded and some of the anodize is gone. Then the lower tubes there are pits and a few little nicks in them. Looks like the previous owner left a corrosive dirt or some sort on there. My question is should I look for a used set of forks on eBay and swap my internals over? Also would the yz450 forms be the same ?

    SSS Upper fork tube question

    Yeah it was kinda dirty , wonder if the dirt was the reason for all the staining and oxidation. Frame and engine have a little bit of oxidation. Wish I really paid close attention to it before I bought it, but little soda blasting will help.
