By looking at the past posts, I can tell that this discussion has taken place many many times, but I would like to get input yet again.
I am going to go to a 416 on my 2000 EX soon and was considering other options since I will have the top end open any way.
Here is what I have today...
White Bros. e-series with 6 discs
White Bros. rev box
UNI foam filter with lid removed
Jek kit with 150 main
other non related accessories
I have read posts about the XR400 cam--
It is just a drop in. Correct?
What other valve components will need to be replaced as a result of the new cam installation?
I am going to go ahead and do Viton seals.
What can I expect to be bad, or good about the install? What other changes need to be made (jetting etc)
Piston:
Probably going with 11.?:1 and continue running pump gas.
JE or Wiseco and WHY?
XR400 gasket to up the compression a little more???
Will I need to do anything to the crank and bottom end because of these mods? If so, I probably need to back off a little (wife thinks this is a cheap hobby).
Thinking about letting Marcums do the machining. Any complaints? How long does it take and approximately how much will shipping cost?
Thanks
