I have the 00' blu/sil busa....And I thought I broke it in on the street from some hard riding....But I brought the bike to dynojet and it was only pushing 157 hp at the rear wheel.They told me that to break in the bike properly you have to put the bike under a load....After doing this and putting on a full Yosh RS3 system and a PC2.I am now pushing 164.5 hp at the rear wheel.But now with that power boost I can't keep the rear wheel from spinning......I'm going with some Michelin pilot sports next.....Because there is nothing left of my stock tire.....Joe
