Sup peeps, I got an 89 Honda TRX250R.  I bought it in pieces and having a hard time figuring out what could be wrong with the thing.  I can't get the thing to start and here's a list of what I did or checked and if anyone could suggest things it would be really helpful.  

Installed kill switch

-Connected short wire with ground and long wire with black/white wire

Changed oil

Changed spark plug

Connected ingnition coil

Fuel line is good

Gas could be a little more

Fuel Petcock has a small leak

Exhaust seems to be all good and connected

I don't see what else needs to be checked and stuff.  Thanks to those who's given me advice and stuff.  Mahalos!
