GT186 +NK Road exhaust

[Covboy]

Hi

Anyone using a gt186 with a nk road ?

If so what are the pro's and cons from your experience?

Would also like to know the main differences between gt186 + nk road vs gt186 + 42mm big bore af clubman

I'll probably be using :
25mm dellorto
17 /46
Sx150 gearbox

Cheers

cant comment on the 186 kit, but AF clubman Vs Nk road.

similar sort of power delivery about 500 rpm higher and more of it.
Didn't Rich recommend raising the exhaust port 1mm to give the reeds an easier life with an expansion.

Have a gt186 with ads3 which I believe isn't a million miles away from an no road. Difference between clubman and ads3 is like night and day. Transformed the ride. I didn't follow Richs advise and raise exhaust port and on first rally with expansion I broke a petal. Still haven't done it but since have doubled up the reeds on that side of the reed block and done 1000s miles since without a repeat and not noticed any discernible drop in power. I run 25phbl through a ram air and some drainpipe with standard sx200 gearing and have done 72mph gps fully loaded with panniers and front rack with more to go (a way off wide open throttle). With af clubman it wasn't nearly as good, tried a hand built mb clubman and that was a lot better but very loud and not as good as ads3 so have gone back to that.
