Review of the SPORTS VALVE by Errol Johnson from New Zealand. Errol races a Honda CB900F and has been testing his new valves out at Pukekohe Park.

"Thanks so much for the work you did on my CB900FA Post Classic bike, it is like a new bike, soaking up the lumps at the recent Pukekohe meeting like a modern bike. By the end of the weekend I was a shade under 3 seconds a lap faster than before, with no other new mods done since last year. I haven't even tried fine tuning it yet as I need to get used to its new handling."
