cam mods

[MacDo]

Hi

I am new here and i just want to be sure about a thing that i eared before.

I eared that if you was changing intake cams on a z 400 for a hot cam that you could put the old intake cam that you already change a the exhaust cam place and it will be better than a exhaust cam.

Do i dream about that or its true

Thanks for answer and sorry for my little poor english

Not sure if it is any different, but yes you can use an inlet for the exhaust.

The tricky part is dialling the cam in, as all the timing marks on the cam sprocket will be wrong,

you also lose the auto decompression, right?

here are some cam specs from the yahoo drz group, it's not obvious to me the intake moved to exhaust is better. The lift is greater, but duration shorter

Clearly the E cams are better than the S

Those figures actually came from here eddie (burned) on this board ?

There isn't enough of a gain to go through the effort
