As long as you have tune ecu, the dongel, and the bike is registered he will be good. The airbox is what is I believe as there are no after market items for it i don’t believe but could be wrong on that. Brocks has a sprint filter available. He ask about that airbox because it could limit his work and he dont like anything on a bike that shows signs of stopping his ability to get what hes after. But hes gonna tune how that bike goes down road, no tricks, no filters off. He likes to tune for best motorcycle can be while staying above 100% efficiency operating throughout which is hard to do. He has a program on wego that shows how efficiently the engine is operating. When hes done, hes wooped, hes a beast worker! Youll test ride when he thinks its done, and he can hook a recording up like a knock test on all 3 and you can see any hiccups and temps in his tune and that thing dint lie, camt hide from that. Youll be happy with his work, and i love paying someone for a service and walk away going, should i make sure thats right.
