I have an 09 race bike with power commander, exhaust system etc. Been reading up a little on smog block off plates, can anyone tell me if this is worth doing or is it something i should leave alone
Have you had it properly mapped or just loaded a map yourself on the PC? You normally remove it when getting mapped as you can get false readings otherwise. Good explanation from timternet: If you decide to have your bike dyno tuned then you cannot run the pair valve system because as it adds oxygen to the exhaust. The dyno “sniffer” is picking up false readings from the additional O2 added after combustion. When it reads the extra O2 it thinks the bike is running lean and will compensate by adding fuel to the fuel map. Now you have a map that is much fat (too much fuel) and the bike will run terrible. The person that is tuning the bike will have to pinch these off every time you dyno the bike. To eliminate this add the smog block off plates.
