I'm really stumped now i tried putting some has down the spark plug hole and it started then died and wouldnt start again so i took off the air filter and hand choked it and it fired once but wouldnt start and now it wont fire at all. I know it has good compression adn the piston is installed correctkly i double checked today the spark is good and it has lots of mixed gas.

 

check for leaks on your intake side (intake boot)

you may be getting some blow by (unmetered air)(creating a lean condition)

 

check carb to boot,,,,boot to head connections

 

they are all tight no leaks

 

when you check your plug,,,,is it wet?

 

yes it is wet

 

from what I have read, Being that you spark is wet then mostlikely of all you don't really have a good enough spark. or you should also check to see ware you spark is going to, if it sparks to the side of the plug then it is your pulg, try cleaning it or better yet change it $5. and it you should also take a compresiion tester to it very easy way to tell. you would be suprised at how high the compersion might have to be. should be around 150 psi !!

 

the plug has excellent spark the best ive ever seen actually. The bike seems to have much more compression now then it did when it last ran so i dont think it's that.


thanks for helping everyone

 

the only last thing that i can think about would be carbed up leaky valve seats or worng spark pulg,

but im sure that you have those good, thats all i got sory

 

anyone else have an idea
