  1. standered jetting from new. In UK hence slow reply. Cheers
  2. I have just had a 290cc big bore kit fitted to my KXF250. All was ok for the first 2hrs of use, now the bike is missing and bogging. I took the spark plug out and it is covered in black carbon. I have had it said to me that the bike requires jetting, does anyone have any suggestions or advise to offer on this? Thanks!
