your boot may also still be leaking - check that it is fully seated and the clamps are snug - if too tight it can leak.
check the front engine ground - if not grounding well it will cause problems.
flip the center clutch diode it will by pass the safety - it some times causes running starting problems.
cut the wire to the kick stand and twist together - that safety causes problems
-- WARNING - if you disable the safety's you can then start it in gear without the clutch in and it may jump - or you can drive with the kick stand down - ( this should be done at your own risk)
