  1. thanks for the help. these are the only corners im really having problems with
  2. i went racing this weekend and i had some good motos but my rear end kept sliding out from behind me in flat corners. what can i do to stop this from happening?
  3. what are the good and bad about the 08/09(if any info) kx450f. i will be having the suspension the suspension set up for my fat arse if that matters at all. its between this and a yamaha.

  5. you would have to split you cases to replace the bearings
  6. no you dont. you just have to remove everything around it. while your in there you might as well replace your bearings.
  7. you sound good for the yz125 the cr125 is a good bike but they are not fast nor reliable as the yz125 from what i heard
  8. hello i am rebuilding my bottom end i was wondering what way the seals go in i wasnt there when my dad took em out . i think they go in with the part number facing you but i am not 100% sure any input would be helpful josh p.s. its a 99 yz125

  10. lk into the 125 the 85 has vertualy no bottom end and the powerband is very sharp. the ktm 200xc or what ver is supposed to be un beatable in the woods and the kdx200 is a very solid choice
  11. that mixture is fine im in renton and i run one size smaller pilot in the winter and stock during the winter. im one size smaller main and 2 leaner on the clip. mine only smokes till it warms up.
  12. dont worry about the main all it does is when your at full throttle. the clip is from 1/4 to 3/4 if i were you id lean out my clip a position or so and that can deffinatly clean it up. if your crank seal is leaking youll notice your loosing tranny fluid. if it is smoking when at idle go down 2 pilots and then adjust your air screw.
  13. a top end rebuild is piston, rings piston pin and bearings. when i do it i also get new gaskets.
  14. that things sweet. hows its suspension compared to newer bikes
  15. can we possibly get some side pics of that kx250. looks sweet:applause: also what year is it
