Motorcycle Questions? Ask a Mechanic.
Hi Mike and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, it would appear to either be a fuel delivery issue (most likely) or an electrical-heat related concern (least likely). Proposed preliminary tries (if have not been done):
Appreciate the post back; still, is there spark? ...does fuel reached the plug? (when "...it won't start...")
Thanks; significant information "...have perfect spark..."
With no airbox installed, cover the carb mouth with the palm of your hand and attempt to start. Please determine if there is suction and if fuel would wet your palm.
If have not been done, perform a compression test or better yet, a leak down test.
The question would be re-opened that an alternate approach may be proposed by another member of the site.
Still, good luck with the Kymco even if I am opting out.
