87 WR 250 WON'T START

There is clearly an issue that caused it to stop and has continued to hassle you. you need to think carefully about what could have happened on the ride.

a bad earth, loose wire..failed secondary coil? something is affecting the running up to half throttle. checked air filter? nothing blocking the airway? what about the reeds, all ok? haven't lost a jet in the carb? ...just throwing stuff out now as all the obvious things covered.

good luck

Check for a cracked reed valve. My 83 250WR did this to me at a race. Never did find the piece that was missing off of the reed petals.

endurokids beat me to it pull starting and broken reeds have been very close together for me. If you can put the piston at bottom snake a tube down into the transfers and blow compressed air before resorting to pulling.

Amusing reading what different folks have for ignitions. I figure if the tech data calls out 70 watts it is sem, 35 or so motoplat mini 6.

This may sound stupid but my 87 xc did something like this too. One time it would start and the next time it would not ? It turned out that the spark plug boot would turn a little between rides causing the spark plug wire to ground out on frame or radiator , so I ziptied it so it cant move around and now it starts everytime. P.S. If it dont start on 3 to 5 kicks it's not going to start, so dont waste your energy. Hope this helps .

I second 84scarmbler's thought... that if it don't start in 3-5 kicks, don't waste your time trying. I learned that the hard way, kick, kick, kick, nothing. I now pull the plug, shut the fuel off, kick it over a few times to clear the fuel out, turn the fuel on, then put in a clean plug back in. Starts every time after this procedure. I'm just back from riding my 87 430 WR today so I got a refresher course.

Both my 87 and 88 430s need the right starting procedure to start. You learn to feel where the piston is near TDC at the top of your kickstarter stroke. Easy to flood, otherwise. Probably not so bad with a 250.

the 80s 250s start super easy...nice long kickers...long as you dont have the earlier bull-horn kick lever....i hate those things
