I was at 9-10k' so I threw in some 10-58's and was revving where I wanted it to but the engine seems like it was running rough. When I came back to 5k I went to put in my 10-62's and thought I should do some weighing. Turned out that the 10-62's came in at 62.9, 62.9 and 63.0 grams and the 10-58's were 58.3, 58.7 and 58.9. I think the engine ran rough because the clutch was out of balance. I know that they need to be within 1 tenth of a gram of each other but where is the best spot to drill/file weight? I'm thinking the backside obviously, but in the crook of it or closer to the tip?????

I'd shoot for all exactly the same weight. There is no perfect answer on where to grind. Logically they weight a different amount because of the varying weight of the metal used. The shape is very close. With that in mind, I'd grind in relation to the mass distribution of the weight. More at the underside of the heel where there is more metal & a little along the rest of the weight. It's a judgement call but avoid taking very much off the tip.
Hello. I am new posting here.
First of all, 10-62's weighing in at +63g is not uncommon. In fact, the ones on my 600 weighed around 63 1/2.
Anyway, for balancing I always lighten the two heavier weights to the lightest one. I use a bench sander which seems to work good.
The variance in your 62g(63g) weights are excellent btw.
If you need to make them lighter than the lightest one, then be consistent when grinding the weights(length of time/pressure). If a gram or more of weight needs to be removed I think you are better off looking for a "lighter" set of 62's.
I sand the sides rather than the back, and of course dont touch the contact surface where the weight meets the roller.
Finally all this means nothing if the clutch balance is out to begin with.
Hope this helps.
Oh well
Thanks for the replies. Just found out that I can't read them though.
