Easy check. With bike idling pull low tension lead from top of stick coil one at a time. If coil is good a 25 rpm drop should be had. If no change, pulled coil bad. If engine dies pulled coil good, opposite coil bad. Confirm by doing same procedure other side.
Remember, pull only the low tension wire. Don’t pull the coil off the plug and don’t pull the lower plug’s high tension lead.
Could be clogged fuel filter and/or leaking fuel pump hoses (internally).

The main plugs that I changed out where pretty good. The secondary ones were black and a little wet, I will pull one of those back out and check them again.
How do I check the fuel fuel filter and hoses? Tank the tank off and pull them out?
Thanks for the advice!
