The work was done at bob weaver in Buffalo when the guy bought it brand new in the 2nd owner and yes these stacks suck lmfaoYep just finished. Those are race track stacks, unfiltered and gritty, its chewing up the Cylinders. Look great work crummy.
Contact Churchkey here. He builds VBAK kits designed for this bike. You get filtration and big air. Ask him to upgrade you to RC1290 K&N's. If he does not do that anymore then first air filter change go to K&N RC1290's you'll feel the difference.
What we still don't know is if your Beast has S* pistons and valve springs and cams and fuel injectors. If you send me your bike's VIN off the steering neck AND the Engine ID off the block I'll see if I can identify if the S* motor mods were done at the factory. Also if there is a white sticker on the ECU opposite side send that too.
If no paper trail then the motor mods were done by a dealer or maybe by a savvy owner. You can manually check. Let's cross that bridge if/when we get to it.
