Starting Problems

[hondamanex400]

I just got done boring my 400cc to a 416cc. i also put a stage 2 dyno jet kit along w/ k&n filter and Full Yoshi pipe. it used to foul plugs all the time when it was stock. after just putting it all back together w/ these add-ons, it is having problems starting. the plug is brand new. it will crank and crank, firing every once in a while. i was wondering what yall thought it was. im in need of a fix quickly cuz im soposed to be riding on saturday. thanks a lot

what is your starting method? try pumping the throttle 3 time without the choke on. crank until it fires, then pumt 3 more time and it should crank until it runs a few seconds. pump the throttle 3 more times and start it up and ou should be good to go.

What is your jetting at?
