just got a call from my dealer telling me that the wrist pins on the
the 670mxz have to be replaced. i hate to have the motor taken all
apart fearing that something we get messed up! how hard of ajob is
this? i realize the cylinder heads have to come off  do they have to
remove the crank shaft also. my dealer said it was no big deal and the
job could be done in acouple of hours.

thanks
mike

Mike,

It is not the wrist pins that need replacing, only the needle bearing in
the piston.  Something about heat treating, or lack of.  Only the Jugs
have to come off, This is something that can be done relatively easy, in a
couple of hours.  

As far as durability?...I really don't see any reason this would be
affected...but I'm sure others have other opinions!

Anyone?

it's a serious job.  You'd hope your dealer has a good mechanic.

Mike,

Don't worry about it, your dealer is "RIGHT"! It's not a big problem!

Hardly. If a putzzz like me can change wrist pins most anyone can. The
only tough part is draining the anti-freeze all over your shoes,
garage floor, belly pan, the brake disc etc... After you get that all
cleaned up it's a breeze. Pop the cooling jacket
then pop the heads for a total of about dozen to twenty bolts. Take
the jugs off (another dozen or so bolts) and then you easily remove
the wrist pin clips (Don't forget to drop pin down in the crank! :-) ) and
then the pin and bearing slide out. You may or may not need a
puller. Install the new bearings and reassmeble.

To be honest this is too easy as compared to swapping out a track.

Two-strokes are amazingly simple.

PS: In regards to dropping the wrist pin clips down into the crank ->
I'm kidding. Do this and you are guaranteed to have a full day's work
ahead of you unless your brother sells Snap-On tools and can get you
this trick little bendable magnet to pick up the clips. It saved me!

Yep, Tom you're right! ;-)

Actually I'd worry more about the average mechanic setting
ignition timing...

MIke,

If it is the wrist pins then the job is pretty easy.  And no, the
bottom end doesn't have to be touched.  No big deal.
