Weeks ago in did the job on bgc

Bike runs awesome, except if I decide to wot from no throttle

I would never do this while riding but wondering why bike us choking out like that?

Just did a 600 mile ride and never had an issue but was aware at no throttle to wot it has this bizarre issue
Almost like fuel/air is messed up or bike taking too much air

This could be dodgy or out of sync TPS.
Do you have Tuneecu if yes check the % and voltage over the tps and see if it's fine.
No need to have the engine running to do the tests but it needs to be warm (+4 bars) otherwise the throttle is held open by the idle control and the TPS will not read 0%.
