My son has a new '08. He says that it is hard to shift. He also said that his '08 YZ 250 t-stroke is the same way. Is this typical to Yamaha trannies, and is there something you have done to fix it.
Thanks for the help.:)

These bikes have something called a clutch Teach him how to use it:bonk:

It beats the heck out of me why people shift without the clutch. I don't care how well you sync unloading the engine/shifting, it only takes a moment to disengage the motor from the tranny with the clutch. Your tranny will thank you for it down the line.

Rant over:busted:

No kidding....It has a clutch?
If your poking along smelling the wild flowers, using the clutch is fine.
When your ripping on the track, many riders are shifting without it. Did ja know?:)

Even while useing the clutch, he is sometime getting a false netral.
I know that on my early model WR 250f, this was also a symptom.
the fix was stiffer clutch springs or add a small washer on the end of the spring where it contacted the pressure plate(see free mods)
Is there such a fix for the '08?

Anyone else have a reasonable suggestion?

Thanks:ride:

No sure where everyone above my post say that your son doesnt use the clutch...:lol:

but to answer your question, both my 06 and 08 were "hard" to shift when new but once they are broke-in they shift like butter :)

Absolutely knew that. It's still my opinion that using the clutch is easier on the tranny and you don't really gain anything by not using it.

I haven't read anything on either the YZ or WR side indicating a systemic problem with the 08 tranny. Like the above poster suggested, give it time and it should loosen up.

Oh, and use the clutch:smirk: :)

well if you are hitting a false neutral, it is rider error. he is not pulling the shifter up all the way and it is getting stuck between gears.
