They are the best pads I have ever used, so bitey. I ran em on my gu which didn't have a built in booster and they were good, not such as good hold as my plaz but on my new Gu which has a built in booster ther amazing
Completly take it to bits and clean everything, after that put it all back together with some really thin grease. Don't use much but enough so that it doesn't destroy your hub.
You running a booster? My reds were mint on my Ko, then when I got my Le with a built in booster I ran a top booster and they must have been the worst thing ever.....
