Addl. 440ex mods?

[atb7346]

I am planning on turning my 400ex into a fire breating 440ex. Below is a link to the package I am going to get. What other things should I consider doing that may be neccesary for this upgrade. Thanks.http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=4555099800&category=43977

Heavy Duty head Studs ;)

[atb7346]

where is the best place on the web to get those. HOw much do they usually run?

[400exrider707]

Heavy duty head studs - GT Thunder has them for like $60

Heavy duty cam chain - www.servicehonda.com and get the 02 CRF cam chain

Those are what I would consider to be necessary

Options:

Full exhaust - your choice
Bigger carb - FCR or Edelbrock
Definitely remove the air box lid if you haven't done so already
Rev Box
Oversized valves
Port Work
Heavy Duty Clutch set up (Plates/fibers, basket, inner hub, and heavy springs)
Suspension work to get the new power to the ground and possibly an extended swingarm to keep it from wheelying over backwards.

Heres a nice list to get you started and just some items to think about if you truly want a "fire breathing 440"
