Hi guys, just picked up a 03 250 SX and love it. Was wondering a couple of things: has anyone experienced any problems with the new integrated rear master cylinder? I talked to Mark Hyde and he recognized it as a problem, he even told me that they wanted to put it on the 04 EXC's but the exc's have a larger caliper than the sx's so the integrated master cylinder could not even carry enough fluid to actuate the brakes properly. I'm worried about overheating the fluid as I do use my rear brake a lot off-road. Also, has anyone tried a flywheel weight for off-road, the power seems extremely strong but maybe too much for woods. Thanks
