Sorry to all that i hav`nt been in touch for a while,but finally after some redesign work we got the results we were after,using the dyno at GT Motorcycles of Plymouth for two days and some 47 runs later trying different air boxes,jets ect we got a 20% increase in bhp over the standard bike, and a 22% increase in torque over another cbr125 fitted with an after market exhaust can.The first system we made was to quiet,but this new design is the dogs.
