will hot cams hurt the life on a engine on a z400 and will it hurt the gas milege.

 

it wont hurt your motor. they will give you more power but mostly used on
motors thats been hopped up and as for fuel mileage
I havent really noticed any difference. I can go around 40/50 miles depending
on how I ride

 

Putting hotcams in will cause a slight ticking noise that comes from the valvetrain.

 

put the drz-e base gasket and heavy duty aftermarket cam chain on to when you do the cams too
