Cold Start
mikesmith:
I just slowly boot it over a few times,choke it,bring it up to TDC,1 or 2 good kicks,and she starts right up.
Timbowe:
Mine too. But I have a prob with the choke. Has to be held open like by hand while trying to hang on to the throttle. Awkward as. But starts great! Usally 1st time. Settles in to nice low idle after 15 seconds. Sweetas.
TomL:
Mine revs up real high when started cold with the choke. It's just because the pilot jet is a little lean. I like it lean though because I do alot of idling in tight stuff and don't want my spark plug to load up. I use a b7es (1 step hotter than stock) plug, but it still runs wet and black if I do too much putting around. Don't worry about the high rev at cold start. Just hit the kill switch a bit to bring it down if necessary. I just let mine scream for a second or two. My KDX220 does the same thing due to lean pilot jet. No big deal!
hughes:
Update. I installed a 27.5 pilot jet which is as lean as I can go with my 87 500. I set my mixture screw at 1 1/2 turns and she starts fine when cold with no reving. She also returns to idle quicker when you bip the throttle.
KXcam22:
For cold starting I always use the rocking method to prime the cylinder. Simply put it in 1st with the choke on and rock the bike back and forth a few times. Apparently is supercharges the cylinder with rich mixture. People look at you a little odd but are mightily impressed when your big bore always starts 1st kick cold. Cam.
