06 YZ450F Problems

I just bought a new 06 YZ450F, its my first Yamaha is there any problems that I should be aware of with this bike? such as overheating, not starting, things like that. Please let me know.

Rejet and change the tires. Oh and the chain cutting into the swing arm all easy fixes.

I agree with yamahacrazy. The only other problem is loving to ride the bike too much!!

The biggest problem is having two riders and only one '06.

The only other thing is that they come with an undersized pilot (42), and they need a 45-48. Everything else is more minor than that.

the stock jetting is ridable, at least here, but could still use the jets already posted. chain stretches like crazy. i adjusted mine 4 times, in 4 different rides, since then i put a did x ring on and still have yet to adjust it. front tire could be better, but ridable if you dont have the money right now. other than that, be carful hitting that throttle out of turns, you dont want no busted rear end. :excuseme:

Go completely over the bike (greasing swingarm, steering head and hubs)

Set the sag, New chain, Adjust some freeplay into your clutch :excuseme: Get ready to be the king of all wheelstand disciplines :bonk:

What I have found with my new 06

Needs chain slider fix, or TM chain slider.

Needs new chain

Needs rejetted

Needs greased (swingarm linkage, steering stem bearings, wheel bearings)

Needs to be a little slower for a noob like me :excuseme:

hey there is a clutch situation!! it doe heat up like crazy and when you adjust it durin your ride it is fine but when you done riding you need to turn it back cus when it cools it ets tiht aain and you will burn it up next ride.. so jsut check it for free play every time you take off after it sits .. its super stiff at first but wow is it nice after 15-20 hrs

there is a clutch sitation on your bike but not on mine.....and that is because you are using the clutch way too much.....that is why it is heating up like crazy.

here is what needs to be done on every new 06 - hopefully before riding it

regrease steerhead, swingarm, pivot and wheel bearings immediately

ditch the stock tires, stock chain - they are junk

check the jetting - go up on the pilot jet 45/48

raise the forks to the line -

oil the airfilter

now it is rideable :excuseme:

other things to do to make it better:

ditch the handlebars they are to low - need Windham bend

buy a skid plate GYTR or Works connection

Hour meter - for true scheduled oil changes /maint

I have only ridden fourstokes the last 4 yrs.. I do not use the clutch to slip it like 2 stroke guys do.. in any case I'll just say that in my case the clutch is more sensative than the 250f'sand big bores I have ridden... I dont know your qualifications nore you mine .so I'll leave it as my opinion to be aware of not abusing the clutch..I have one up one tooth on rear to make third more useable for me.. it has cut down on shiftin and seems to have worked well for me ..

MY clutch acts like that too. I have to really watch it. In fact, not watching it cost me a clutch pack already, so now I'm quite aware of it :excuseme:

I rarely touch my clutch after a start, so.... i also have a 50t rear sprocket.

What oil are you using? Im using shell rotella t 5w40

agreed.....no offense meant. Just that I ride the stink out of mine and clutch is perfect.... :excuseme:

Amsoil Baby! :bonk:

I use my clutch ('06) as much as I ever used the clutch on my 2-stroke YZ250's.

Its as robust clutch as long as you "get in and get out of it immediately" (just poke it to get the revs up). However, if you keep your hand on it letting the clutch plates slip, well, I guess you can kiss it goodbye in short order.

Probably also has to do whether you are a "shifter rider" or not. This transmission is the best I've ever had on a dirt bike in recent memory. So I tend to use a lot of gears. I even speedshift (clutch + full throttle) almost all the time. Still no clutch issues However, if you insist on riding the track in 1 gear, I really don't see how you can avoid slipping the clutch since a quick stab in slow, tight corners is pretty impracticable. So its risk stalling or play slipper clutch. And the latter will wear it out real fast.

When you use the '06 clutch, just dump it hard and quick. If you do that you can use it as much as your heart desires.

Thanks for all the tips guys I really appreciate it.
