got a qestion....i heard the angle job on your valves will really pep the ex up, but is this true and how much will it help....is this the same as "port and polishing head work" just wanted to know because im fixing to get allot of motor work done to shut these yamy boys up....thanks

 

yes it is!!!!!!!!!!!!!!!!

 

What is involved in an valve angle job on a 400ex, and what are the bennefits in performance?

Thanks,

Anthony

 

Save your money and save your time. You will never know it was done.

 

i run right with the ds650 with the stage 1 kit on. you have to do it all to get the full effect
on what it is intended to do!!!!!!!

99 426ex,11:1,web cam,3 angle port job,rev box,
dyno jet kit,6 air box vents,super trapp pipe,
= lots of power!

 

porting is not in the valves, it is done in the head to increase flow

 

a 3 angle valve job just refers to the way the valve seat is cut, on your EX you wouldn't even be able to tell it was done.

put that money into a higher compression piston and a slightly more aggressive cam, and you would have something
