Message: [QUOTE="wrooster, post: 93699, member: 21800"] grunk250r-- false! my brother has the yz250f, i have the wr250f. both were dleivered in late feb '01. the yzf was perfect from the factory. my wrf required a tweak (~0.5 turn) to the fuel screw to lean out cold starting. delivered it was too rich -- one indication of too rich is that it is easier to start the bike cold with the hot start button pulled out. this of course makes hot starting difficult to nearly impossible. so adjust the fuel screw if you have trouble starting. in addtion, starting gets easier with some miles on the bike. now both bikes start with 1 to 3 kicks hot or cold, and generally on the 1st or 2nd kick. of course when cold you use the choke, and when hot you use the hot start button. once you have "the drill" down it's pretty straightforward --> gently kick until hard (=TDC), pull comp release, kick 5-10 degrees more (just past TDC), return kickstart to top of travel, and kick like you mean it. also, we're at 100' ASL, using 93 octane pump gas, did not have to change jets. ps never kick thru TDC without using the compression release! some folks have snapped their kick start shafts (not the L-shaped kick start lever but the shaft that goes into the engine) trying to start without using the compression release.
