How aggressive coming up? I now how you get down with it. I know the fdr #s but real life pull can be big would you go higher than +3?
Well, I had no problem wheelieing it stock, but the +3 alone was noticeable, then the flash added more timing lower in the rpm.
So, with a fast half twist of the throttle, it power wheelies easily.
I could go 80-100mph in 4th, let of the gas for a split second, then nail it wide open...a d it would power wheelie about a foot in the air.
As for regular, balanced wheelies, it just felt more fun +3 for me, as well as feeling noticeably quicker accelerating.
2nd gear wheelies balance at 100-120mph if you don't slow it down first too, then they'll hang around 70-80mph.
1st are 60-70mph, again unless you slow them down, and I'm not very good below 30mph anyway(I need a stuntbike for that, and that's in the future too).
As for bigger than 46, I personally wouldn't, as 17/43 to 18/46, and any combination of either and anything in between, all fit the stock length chain.
The Toad and the old Pirate both run/ran 47t rears, but also ran 55 series tires, so equivalent to a 45.5-46 with a 50 series for overall gearing.
Going any lower is going to give the bike more of a tractor feel to it, torquey noticeably lacking top end.
With 18/46 and a 50 series tire, you still have a 175+mph top end too.
Swap back the 43 and it's capable of 197mph(gen2, restrictions removed)
