Hi Doing a 600ss project ie cafe racer, ttf1/2 rep, something along these lines, still in the early planing idea stage. Seen some threads and projects about Head reversal work. Is this for performance/tuning or is it get the look of the engine right on some of these projects that i have seen and read about. Do not really no a lot about this. Be interested in hearing reasons why, what other work is needed, I presume the valve timing would have to be changed? I'm handy with the spanners but not with engineering work. If i go down this route is there any one out there willing to do this type of work on the head and what sort of cost would be involved. Also on the look out for spoked wheels, like to keep 17" size for tyre choice. Probably going to use zx6r rwu forks. Thanks for any info or help
