Do I need.....

[EXDUNER127]

I am building my 400ex with a std bore 11:1 piston and hotcam, and ported head. Will i need a longer swingarm to race up hill or flat drag.Do you guys with 416's get alot of front ends popping up with full throttle?

I had a 440 and when I got it I bought a lowering kit from durablue and I never really had a problem with the front wanting to come up.

how much difference will an inch on the swingarm make?
