'13 Strada still won't start

It started out as what I thought was bad fuel so I drained the tank completely and added 3 liters of fresh non-ethanol premium. Also new spark plugs, checked the air filter, checked all fuses, cleaned up the ground, battery fully charged...still won't start. The motor turns over well but doesn't want to fire. There is a spark on the horizontal cylinder and plug looks and smells like fresh gas. Checked all connectors leading to plugs. Bike ran fine last year with the Eldor coils I had installed over the previous winter. Hmmmm...WTF

I was wondering if there was a clogged fuel filter but the whole fuel pump is replaced as a unit with no separate filter and seeing as list price is $1123US, don't think I'll be replacing that on a guess.

Any suggestions?

Maybe not engaging or broken sprag clutch? It's a weak point in Duc's. If the starter turns and it's making spark, it must not be physically turning the crank. Easy to mess up if you replaced the starter yourself or cracked the left side of the engine case. Read my entries on the starter DIY.

There's some YT vids on diagnosing bad sprag clutch.

I'm pretty sure the crank is turning cause I can feel puffs coming out the pipe.

Know what you mean about the starter, I replaced 2 on previous Ducs and used a little tool from Desmo Times to remove the case side.
