00 RM250....losing my sanity

[GoonRider200]

I am completely stumped...the bike was running perfect. Went to ride it two days later and it would not start. I changed the plug, still nothing. I have had the carb apart 3 times and everything checks out. It is getting fuel, the spark is strong and the bike has plenty of compression. The bike should at least try to fire but it won't even pop. Any ideas or suggestions to look for here?

Is the rads still full? Kick it with plug out and wfo - see if anything is coming out. Maybe flooded?

[Tailender]

Is plug wet or dry after trying to start? If wet, float shut off valve may not be closing off fuel to carb. Turn off gas and hold throttle wide open and kick to start. When you turn gas back on, bike should want to flood and not run good except maybe at wide open. Air filter could be realy dirty and blocked. Let us know what a new plug looks like after trying to start. Gas is fresh?

[GoonRider200]

It has fresh gas, the float isn't sticking because it isn't puking out the overflow and I did already try kicking it with the petcock off. Air filter is clean and the plug comes out wet but not overly wet so it is getting fuel. I am getting spark but that also doesn't mean it is sparking under pressure in the cylinder. Right now I am almost thinking it may be electrical/timing issues. Nothing else makes sense.

For the hell of it, check for a broken reed,,, there was another Guy on this thread that had the same problem, and, it ended-up being a broken reed..... it may not be Your problem, but, it's worth checking.......good luck Bubba.........Dr.D..

I checked the reeds and they are good.

Hold the throttle wide open and kick it.

Hold the throttle wide open and kick it.

I did every time I tried to start it and it wouldn't start thinking it may be flooded but it did not work. I am lost right now and i might start testing the electrical system to see if everything checks out there.

The old electrical gremlin. Either that, or a timing issue. You seem to know your way around the bike good enough to rule out the typical "Doh" stuff...Time to start checking wires and such! Keep us updated.

Is this bike new to you or you've had it a while and know the starting drill that it likes?

Just for the heck of it check that the stator is tight or even the stator plate bolts. Then also check that the key did not get sheared between the stator and crankshaft. Then the last thing I could think of, since it seams like you covered every thing else, is to see if the crank seals did not pop out on either side of the crank. Did it smoke a lot the last time you rode it?

[GoonRider200]

I bought it in the spring and rode it all summer so I know the bike pretty well and have the starting drill down.

If I was in your boots right now, I would pull it untill it started. You know the bike and you know it was running fine and now nothing. If you did not turn the gas off the last time you hauled it home or left the gas turned on in the shop while sitting, it could have flooded the cylinder. Plus you have been kicking on it for a few days now.

I'am an Okie Redneck, and we just like to pull stuff for kicks and giggles, but I bet it will start.

[BlackCR25098]

Yea could be the float is set wrong and just letting gas pour in. Didn't you say there was a leak or was that someone else?

Yeah, that could be a possibility,,if so,, pull the plug, and turn the bike upside-down, and drain the crankcase........ I've seen it before.......good luck........Dr.D..
