I was wondering if there was a stage1 and a stage2? I know it is a DOHC, but All I find on the net is intake and exhaust no stage specifications. Also do you have to replace your stock springs ect? Thanks for any help.

 

Anyone?

 

Some people refer to the intake only as stage 1 and both as stage 2. In all actuality there isn't any stages in hotcams for a z400my z-400

 

Can you use stock valves and springs with both?? Thanks for your reply.

 

There are 2 diffrent hot cam stages for the Z 400 you just have to look around or call hot cams, they have diffrent specs. Ans yes you can use your orignal springs with either.

 

You will lose low end w/ both cams, but it will rev alot better. Not sure how one cam would affect low or top end.. A rev box is a must as it revs almost to quick..
