Heres my 98 yz400f Queensland Australia.

It's actually a 444cc it has a 426 barrel and with oversize wiseco kit and hot cams to match. Dyno'd at 52hp. Still the nicest 400 if seen in the country. They are getting rare here.

Thats cool mine has a 426 head with a 444 oversize barrel and hotcams. Its an animal

Here's my "Street Legal" California Plated 99 Yz400 that I got last year.

Bike still needs work, but runs great and a blast to cruise around the city with... Previous owner pretty much effed up the carb, but I upgraded the carb to a 06 450.

Also the previous owner messed up the head and got a hairline freeze crack in the head which they jb welded it and ran it that way for 2 years they said... I've rode it around on a couple hour cruises around town and its fine... But it's def next on list to get fixed... Plus maybe adding 5th gear.

Does anyone know if I can use/put a 2000-2002 Yz426 head on it to replace my current head?

Got the bike for stupid dirt cheap, and when I went to register it at DMV ended up with plates for it(after a brake and lamp inspection)

Mine is a 98 400 with a 426 head and works great, pulls like a train. Didn't realise that they made one with 4 gears??

"They" didn't.  Very rarely, you find one that was set up as a four speed for a race team, and the first generation YZ450F was a four speed, but otherwise they were all 5 speeds.
