View Full Version : K 90 customization question

09-21-2007, 02:22 PM
i just recently got into the customization business and i'm just wondering if what im doing is wrong. i added about 12 grams of lead to the 3 and 9 oclock position on my k 90 and im wondering if this is bad or should i add some weight to the 2 and 10 oclock position instead.

feedback from k90 users would also be much appreciated

Why did you add weight? How does the racquet play? How are we supposed to know whether or not that set-up is good for you?

If you don't know what you're trying to achieve by adding weight, maybe you shouldn't do it.

i added weight cuz i wanted more stability and it plays just fine

More stability? Than a k90 stock?

In my hands the k90 stock is the most stable racquet I've ever hit with.

Did you typically play with 13.5+ oz racquets? Mine two k90s come in at 370g without extra weight.

If not, you may want to remove the weight and try different strings and tension to get better "stability." Adding 18+ grams to an already heavy k90 may excessively stress your arms, shoulders, or wrist.

reduce the headlight by some 2 points. i added a lead tape and a damper and it's so stable :) but mine's the asian version

The K90 is 12oz (340g) stock isnt it?

My racquets are stock, and combined with a fairly tight poly string with a decent dampener makes for a really solid, crisp racquet.

I think you can add it inside the butt cap, by opening the trap door. I tried it, added 3 grams by rolling up a 1/4 inch tape, then sticking it with double-sided tape.

BUT unfortunately, after hitting abt 4 hours, the lead tape came lose and started causing vibrations in the racket on off center shots. Any idea how to fix this?? Would super glue do the job?
