Hey what's guys this is my first post. I raced my brother on his raptor 660R this weekend all he has done is full pipe, K&N air cleaner and gearing change. I raced him a bunch of times on dirt and pavement he beats me every time. Even if we start from a roll we are dead even nobody pulling away. My mods are FMF gnarly pipes powercore silecers,boost bottle,boysen reeds,+4 timing,toomey air cleaner kit. Does this sound right or is my banshee low on power for its mods. thanks for any help.
