"What's that about hindsight always being 20/20?!" :lol:

Problem: Intermittent engine bogging issue shortly into ride. Similar to what it feels like when a 2 stroke is fouling a spark plug. - Engine would run perfect in garage and in staging area, but 5 minutes or so into ride this problem would present itself. Very short in duration, and when not bogging out, engine would seem to run perfectly.

Solution: Both my battery terminal cables were loose. Tightened up, bike runs as good as new! :cheers:

I actually went through the entire gambit of solutions before realizing what it was. It took several days and a lot of teardown, assembly time chasing down. :? This included checking fuel pump, changing fuel filter, checking injector, changing spark plug, and finally trying to chase down electrical short that didn't exist; fun fun! And yes, after I discovered, I was both pissed off at myself and happy it was so simple.

So if you're some what new to the battery operated, EFI dirt bike world like myself - Don't assume its something mechanical before you've thoroughly checked electrical; Start by checking your battery condition, connections, and fuses first! :roll: - Hope this helps someone else, Happy Trails!
