please post here: YES woodruff key problems
Posted February 19, 2003 - 12:25 PM
Several members have come up with some great ideas on getting to the bottom of the Woodruff Key issue. I would like to bring all the information together for documentation purposes. The 30 day warranty period is expiring for many new owners. I would strongly recommend that you contact your dealer concerning this issue and keep a record of the date you brought this up. By bringing together specific data, we can increase our standing if we run into further problems in terms of Yamaha taking care of this problem. In addition, we might be able to find a pattern related to production date, state of sale, miles and torque.
TO MAINTAIN INTEGRITY ONLY POST THE REQUESTED INFORMAION. FIND ANOTHER POST FOR OTHER COMMENTS.
Please post the following (try to keep in order)
Name, date of purchase, serial number, state purchased (or county for outside of US), miles on bike at the time of key failure, any torque adjustment after purchase prior to failure..

Two other bikes in Memphis with less than 20 miles with failure

5)Failed at approx. 50 miles
On a side note Yamaha told dealer to torque rotor nut to 61(I made them call twice) They also said they had no knowledge of the incert calling for 47 and requested my dealer fax it to them.

Broken woodruff key at 32 miles, along with the left side case cover. Dealer fixed.
Now we are going back tomorrow for a shifter that doesn't want to come back up (now at 56 miles). Saw this on TT, that there is an adjuster that may iron out the problem. Sure hope so.

Our new bike idling in the shop, it stalled, the when refired, held throttle open a little, pop and backfire, sheared key way. Even tho the dealer did the yamaha bulletin, which most dealers dont even know about.
We disassembled, found out the tapers are off slightly, lapped the flywheel in, took about 5 minutes with valve laping compound, 120 grit, works great. Tighten to spec, made it a day without a failure.
When we blued up the taper, they dont match, only by a few 10ths of a inch it is off. Lapping it in will ensure that you match up the taper, and you will know when it is matched, the shaft will turn a satin grey without any shiny spots.

My number is 0389.
Has anybody been able to talk to Yamaha directly yet? I think we need to stand up to them and get it taken care of. We have a real short warranty on these bikes, and need to make sure they are fully aware of the number of problems.
Even if our warranty expires, if there are enough complaints, and they find it to be a factory defect, they should step up to the plate and take care of all of us!
If anybody has actually been able to get in touch with Yamaha, it would be helpful to the rest of us to know exactly how you did it, so that we can call too.
