I have a 88br too but it feels kinda like it has no power. And i only have 1 radiator. 88br Mvt srace 80 90 Malossi vl6 360 intake 30 motoforce pwk I think the stock ignition holds it back.
The reason why it so rapid whit the rpms is the electrics (mvt or something)but it dosent help alot maybe couple hp more but you could get almost same hp whit right tuned cdi on stock electrics and the reason why it is so rapid is the light flywheel it dosent have that much power than you think.and the flywheel dont have anyneffect when you ride it or maybe in 1st gear.
