@imagoas has been said think about your suspension setup its worth spending money there as well, makes a world of difference in the real road going world
58 now and the 260hp light weight Harris is a joy to ride. The power is just some thing you get used to, just means you don't have to thrash the bike to play with modern stuff
My big valve flowed heads on my turbo bikes make more power than the standard heads. The better these engines can breath the better in my opinion (air cooled & oil cooled) . Your only looking to make 200hp so just turn the boost up
