go for it, i used to think the same way, im kinda leaning towards n/a sr but i still might take the ka path. ive never seen a streetable 200whp ka before, i kinda gave up. lol be prepared to spend some loot, it'll all be worth it tho. n/a is fo balla's only. i see about 170whp range with that setup, thats what scooter made with jwt cams, itbs, header, exhaust, and a real tune. there still more room for alittle more power also. like high comp pistons, knife edged and balanced crank, port and polish, clover leaf weld your head, over sizes valves, 5 angle valve job. haha lots of money, head work alone can cost like 7 grand if you want everything done.

Nice write up...very helpful to a noob like me! Thanks bro
