WHATS A TRE?Yessir Flash it or get a TRE
This is, lol
186
But if you remove the top speed limiter, you will have more.
Is your bike tuned, or are you using a generic map?
As for the K&N most tuners will tell you you that the filter is a restriction.
Sorry, only know that the guy who traded it in was meticulous about everything so infer what you can with that.
this might give you a rough idea on HP/TQ: https://www.hayabusa.org/forum/gen-ii-busa-information/159542-gen-ii-busa-what-does-really-make.html
And unless you "remove" the factory top speed limiter, you can only go 186 mph (regardless of what mods you slap on it)
Stock gearing on any year gen1(17/40 gearing) that is or has been desrestricted has a potential top speed of 194mph.
Stock gearing on a derestricted gen2(18/43 gearing) has a potential top speed of 197mph.
This is what the bike is capable of, rider weight, temperature, humidity, wind, elavation, ect., all play a big part in whether or not you can actually go that fast.
A gen2 needs a 41t rear sprocket, or a 55 series rear tire with the stock 43t sprocket to be able to break 200mph.
Ballpark gains from full exhaust and filter are 10hp/5 ft lbs trq...give or take a few. Every bike and dyno are a little different.
So what is a good gearing setup that you would recommend for a gen1 to hit the big two-double-O?
