sweet ride mate, with the 23hp estimated is that at the crank or wheels, id be lucky to get 18 hp at the wheels with my 155z hi-comp piston and V2 head with s35 cam, you maybe more looking at 15-16 at the wheels for the postie. But its a sweet ride and thanks for sharing. Thats just my opinion and i may be wrong dude.

Yer at Crank, told there 19hp standed, cam an that has made it feel like a 4 hp improvement at gess, yer gos allrite for a postie but want more power, so am tossing up if i should get a 190 anmia or just spend the 1300 on this 1, what's the best option for reliable hp?

From what i could find the 155z/160ho have around 10.5kw/14.07hp at the wheels in stock form. Does anyone else have figures? You could look at going big bore on the 160 and also the V2 head which has s35 cam roller rockers and huge valves. TB 184cc Bore Kit, Race Head V2 and 28mm Carb Kit
