take your carb out, clean the entire thing, that means every nook in that *****. do this and if still a problem write back because in most cases were n idiot is involved, this is the most over looked problem

SOURCE: Bike won't start

so where did you find the bad ground, and if I wire the negitive side directly to the frame can that be a permanant fix? Myne is doing the exact same thing

carb could be clogged with trash even though fuel is gettin to carb the main jet could be blocked not letting fuel enter intake

SOURCE: no spark at plugs when cranking over

Sounds a lot like a failing battery. The starter's pulling enough power that you aren't getting spark. You could try using jumper cables from a car battery, see if you get spark when cranking. Be careful! It's way easy to short stuff out with those jumpers.
