I am busy rebuilding my wifes 400ex. Have already purchased a JE 416 High Compression piston.
We ride trails here in the desert, plenty of dunes and drop offs so not many oportunities to really open up. What we are looking for is a little more Top End (Just to keep the Z400's out of the way in the few straights the trail does have) but mostly aggresive and snappy torque for acceleration and mid range power.
Should I also replace the cam and with what? I was reading on Doug Gusset's site about the BigGun CDI :) which received a very strong nod of approval from himself and his techy's. But they also seemed to say that Piston + Cam + CDi is the way to go. Individually the components will be "flatish' in performance increase?
Dramatic Top End increase is not the aim of the excersize. A little more will be good but it is the instant acceleration and torque in between and over the dunes which is going to keep her way out front of the Z400's so when the straights come they have to catch her first before they can over take.
The budget is limited and everything will have to be imported so what ever I get has to make a difference and be real value for money in both reliability and increased performance.
Can anyone suggest gearing? She is a weighs in at 130 pounds.
Appreciate any constructive advise. :)
