I really respect your point of view...makes you sense...
1 - A flash and the bike is not limited.
2- correct, the bike barely gets to near the limiter in 6th even with flash... mine has like 193hp and -1F gets 13700rpm in the data logger when riding here in 6th gear.
3- Bring you bike to Dominican Republic and get ready to ride really fast.... more than a couple of bikes here blown up in the way from Sto Dgo to Punta Cana... long straights and 130+mph curves. for 50kms.
you need top speed not to get records, you need top speed because when you ride with guys that can ride fast you need all you can get, and my experience is, you get 2 short and the bike just revs and revs and dont move forward (hope I make sense), 2 long and the bike does not get to the sweet spot, you need the bike short so it can move the bike when winds are not helping and when the wind favors, the bike the power does not drop...
-1F and +2 on the back you lose on a gen4 like 6mph
the shortest for flash stock power would be -1+1.
