With no codes, I would be a little suspicious that the valves are not closing. Maybe the push rods are not adjusted right. Just an outside guess. No compression no fire.

That was exactly my first thoughts ih4x4, first thing I did was reposition and check push rod adjustment. I would think the plugs would fire even if the adjustment was not right. I have pulled the plugs and checked them outside the pistons they don't fire at all.

Ok so I'm a real dumb a##. I have got fire. Plugs won't fire if you have both plugs out of the bike. Says so right there in the manual.

Problem is now, bike still won't start?

Do you have the correct plug wire going to the correct cylinder?

Yes sir, best I can tell at this point is I am getting fire and I am getting fuel but I am not getting combustion. I have checked the battery for voltage but have not checked battery load test. Is it possible the battery could be weak enough to not let it start?

If you have fuel and spark,the next thing needed is compression.
Valve timing off?

OK so ran compression check, 120 psi front cylinder, 122 psi rear cylinder. That look about right?
