hey i got a z400 and i was wanting to know what the best mods for it are. i got yoshimura pipes and nerfs and i want to know what to do next. what do you think is the next quadmod that will give me the most performance and the most advantages on a track? (kfx or z)

 

whats up local boy, My brothers Z has the Pro Alba Kit on his and it came with a pipe and header, K&N filter and jet kit pre-filter and speed decals!(haha) I would go for the K&N and jet kit with a pre-filter, put a few small holes in the airbox lid and pull the snorkel and you will fell the power.
