try push starting it.
there's a trick to doing it, for the old and gimpy, yes i'm talking about myself.
set it up just like you normally start
cept put the kick stand up, put in 1st, others will say 2nd or 3rd
i say 1st cause when it kicks over it's going to sputter and die if you take the clutch back in.
so, clutch in, stand up, run on, 1st, and you're standing beside it.
now run like heck, don't forget the bike
jump on and push the starter button and immediately let out the clutch.
as soon as the clutch goes out, it'll lock out the starter so don't worry about letting go of the starter button. it'll chug chug thump thump thump...
you might want to have it in prime to make sure the bowl is full.
and i've been thinking of taking the starter cable off, it's only one nut, and isolate it somehow. but it might make it a little easier.
