Hello! I was just stringing a Yonex MP88 following the new yonex stringing pattern at 22 lbs. The result was that the racket broke at the 14th hole. It broke while I was nearly finished with stringing the crosses. The racket haven't any signs of damage form a previous crash so I'm a little bit stunned. I was stringing quiet a few rackets yet and I haven't found a n error on my side. Now I have 2 questions: First. How is Yonex warranty working? Is it easy to send it in directly to yonex and get a new one. Since it's clearly a production problem.Or have to be there any precautions? I'm living in Germany and the racket was also bought there. (Have a similiar problem with my MP99) Second. Surely the new stringing pattern introduces more stress on the lower part of the racket (near the T-Joint). I'm not sure but I think the upper part is more flexible and therefor is able to handle the stress better through flexing. Is the new stringing pattern obsolet?
I am not a stringer, but I thought the 'new' stringing pattern was for AT800 and Nanospeed series racquets as they have extra grommets. I would have thought that you would simply damage a grommet though, not break the racquet at that tension.
warranty. they should provide replacement. A broken racket during stringing is reconizable.. You can try the agent or the website. rgds
0) do not cut the string or remove the string. 1) make sure you have the right distribution code and it is still in warrenty. 2) contact yonex in germany or in eu. 3) they will give you a instruction to to send in for replacement. good luck. 3) they will give you a instruction
not that simple this time. because: 1.warranty had expired (unless it was a recent purchase of an older model) 2. if it was truly a manufacturer defect, mp88 is out of production. Your dealer has to search for other retailers for mp88 replacement if yonex agree to factory defect. 3. since u had clashed before, yonex's technican can spot that.
14th hole from where, bottom or top? Also, how did you start with your cross? From top? Middle? Or bottom?
Thanks for all your replies I will talk to yonex this week and then we'll see. 14th hole from bottom. Started with mains;-) and started the crosses on top.
I see. With 22 lb, a racket in decent shape suppose to survive. Surely worth a try and hope for the best. However, like cooler indicated, the process might be a bit difficult, especially if you own the racket for quite a while (i.e. can't prove previous usage damage - clash, or string job...) Best luck.
The Yonex UK racquet brochure says the max stringing tension for MP88 mains is 19lbs, and crosses is 21lbs. Wouldn't trying to string it at 22lbs invalidate the warranty? That is for the 4U version anyway.......
MP88 is out of production? when did that happen? It's in the 2005 Yonex UK catalogue (well pamphlet )
oops, i forgot. I dont see sponsored pros using it anymore tho. The red mp88 were discontinued for more than 1 year already. The blue on is still in the 05 catalog.
pic? Could you post a picture on it.. I do not understand what "NEW" pattern you've used? There isn't any new pattern for MP-rackets I know of.. /Twobeer
If you send it back and Yonex find a manufacture defect they will most likely send a replacement blue MP88, I know someone who got 2 old style red ones replaced with blue ones
I've just used the new stringing pattern yonex recommended for "ALL" rackets except AT800. At least that's what is written in my yonex cataloque. A friend of mine told me I should use this pattern since yonex could make some problems in warranty cases I will post some pics tomorrow.
baumbaer, sorry to see the loss. i noticed you are using an Eagnas machine. the side supports are poorly designed and very very very prone to slipping. in normal situation when the supports are secure, the crack should not have occured. did you tighten the supports adequately?
oh nasty . . . I feel sorry for you. How come you are using a tennis clamp on one side and badminton clamp on the other?
the sidesupports were tightened correctly. It's the first time I cracked a racket on this machine. I should have strung some more than 50 or 60 on it. Actually I think the crack is due to the new stringing pattern. because even when I started the crosses with the same tension as the mains (22lbs) the top of the head was deforming itself much more, as it is the case when I start the crosses from the bottom. But perhaps the racket was already too weak to withstand the tension. I'm using a tennis clamp because my other badminton clamp has a very uneven surface on the inside. Lets see what yonex is saying.
Structural Failure Baumbeer, The crack has all the telltale sign of graphite failure. How many times have you strung this racquet? Regards, Pete
