Top speed of 80 is due to the carburettor installed in it.
I had installed Honda cd 100 genuine carb in my altered bike speed was not exceeding 80. Whereas with my dekni pz22 it would reach 100.
Pz22 are performance carburetors they are very aggressive. Engine idle was aggressive on it. But pick and speed was bombastic.. Fuel economy is low on it. However riding at average speed not much difference in economy .
If riding at 60-70 bike has more power on pz carb then pb.
Pb are very soft smooth carbs. Good for average and smooth ride. Engine is much smooth on it.
