Woodruff Key Update: TSB On The Way!

[rohar]

Hi all.

I just got off the phone with Yamaha customer service. Aside from being very helpful, they did confirm that this is a known problem although the person couldn't offer any details as to what happened to cause it.

The good news is that a service bulletin is on the way to the dealers. The issue is so new that it hadn't gone out yet.

Interestingly enough, the TSB is not just about retorqueing the nut to a new value. She also mentioned that there is a new "procedure" that goes along with it. She couldn't offer any details. If your dealer doesn't know about it, have them call Yamaha Tech Support for the TSB, or wait till they get it - it should be coming soon... I hope.

"The issue is so new that it hadn't gone out yet."

LOL. ? Yamaha has known about the problem for months. They haven't exactly been quick to react.

For what it is worth, I talked to a dealer in Ontario today and they just some recieved paperwork, I can only assume a notice or TSB, he did say it was concerning the rotor nut. Either the Canadians are slow to get the info that we have heard about in the US or hopefully it is something new?? I will request a copy of this info this weekend.

Paperwork??? What the hell is that?

I don't buy it.

They are also going to adjust the carb to prevent backfire also.My bike is at the dealer now for this and SHOULD be done on Fri.I will get all details when I pick it up and post them for all you guys that need there keys fixed ok.

Umm....most guys on here have already "adjusted" their carbs. jetting, etc. what exactly are they adjusting at the dealer to prevent backfiring ? ?

[ThumperWR450F]

i heard they are replacing the piston and rod with a gerbil and a wheel . figuring how bad could a gerbil fart be. ?

[foursmoke]

what exactly are they adjusting at the dealer to prevent backfiring ?

Not quite sure XR600R but will find out what on Fri. Also will find out what rejetting carb. afterwards could do.

on friday i was on my way to my first race, when i stop in to my dealer for some new googels and they had the up date. took about 1hr to do. they took off the fly wheel, lapped it , appled locite, red or blue? torque to 51 lbs. and retorque to 51 lbs.

SEEEEEEE!!!! Just like I originally suggested! Just like we do the Cobra clutches! Damn I'm good! (Now I better hope it works! ? )

BTW: Use red or it's dead!

[IceBox]

I don't have a long standing relationship with this dealer so I am anxious to find out also. Saturday can't come soon enough for me!!

All they told me was that it was "adjusted". It wouldn't run with the choke off when I dropped it off and ran great after I picked it up (still a little lean on the pilot jet, though).

Same jets. All they could have done was adjust the air screw, but I previously tried everything from full closed to full open and it never ran as well as it does now.

[foursmoke]

took about 1hr to do.

My dealer wont do it without a new ignition cover gasket! &%$#@!! ?

[jackalope]

Anyone from CA having this problem? I know of 6 bikes that don't or haven't yet had this prob! Dealer said they haven't gotten anything yet. Weird! Yamaha Corp. is only 20 Mins. away!

[foursmoke]

I haven't had problem either. Just airing on the side of caution. ?

[Alabama_Rider]

They considered it but fart gas does not meet EPA emissions requirements.

I have the Technical Bulletin in my hands. According to this Bulletin, number M2003-005, The starter clutch bolt should be torqued to 16Nm (1.6m - kg, 11 ft - lb) and Loctite applied to these bolts. The main rotor bolt, is to be torqued to 65 Nm (6.5 m-kg, 47 ft - lb), then loosen and retighten the rotor nut to the last spec.

The Bulletin DOES NOT specify Loctite to the rotor bolt, yet I cannot see where this will hurt.

[WR321]

Can you post this TSB, I would like to take a look at it.

Has anyone checked the torque on their starter clutch bolts?
