06 drr50 won't start HELP!!

[fultz416ex]

i have a 06 drr50 that i can't get to start. I just put a new oem carb and moved the old jets over from old carb. everything is clean. put new plug in it. it has spark, but can't get it started. i have ridden it with new carb but one day it wouldn't start and i haven't been able to start it since. any ideas? thanks

spark, fuel, air

Compresion could be low might need a piston and ring or at least a ring. Helped a guy at the track last weekend with same problem your having. Had good spark and fuel.

put a new plug in it and some starting fluid and it fired right up. rode it for about an hour today and when i brought it home, it wouldn't start again. might be time for a top end?

my sons 07 drx50 quit on him one night after his first moto..couldn't get it started..fought n fought n fought with different stuff..come to find out, when i unloaded off the trailer i hit the pull out kill switch in the back by the grab bar,and it fell off after he pulled into the pits..never even thought to look at it till a week later,and countless trial and error fixes..LOL, it's always the simple things

Another tool you'll need is a compression gauge. At about 70PSIG the two stroke should not kickstart.
Then again a plugged exhaust port or exhaust pipe from too much premix oil can cause this problem. Also a bad crankshaft seal. Poor electrical connections, spark plug cap being bad, a bad tether switch, and the list goes on.
Does it ever miss or pop when it does run?

thanks for all the help. it runs great when it runs. haven't ridden much lately, might go tomorrow.

he is only 4 and is having a hard time with the brakes and his little hands. wildcat is an awesome track for sure! does anybody know if there is a foot brake kit for a 2006 drr50? thanks
