i just picked up a "well used" 2001 200 exc. i have been wanting to get back into riding for a long time and i just could not pass up this deal. the bike is rough looking but fires up first kick and seems mechanically sound. unfortunately i have been out of riding so long i have never had a bike with rear disc brakes. the disc pads are not even on the bike. the guy i bought it from had the pin but not the 2 cotter pin type things that go into the 2 holes on the pin. it seems this "pin" is all that really holds the dics brake pads on. i have ordered disc pads and a pin(which i am assuming comes with the 2 cotter type pins). my main question is how do i compress the caliper which is now fully extended, so i can put the new disc pads in. also it is missing one of the tangs that the 2 exhaust pipe springs hook onto. the one that is still on looks like it just bolts on. any ideab where i can get one of these? and while i am at does anyone know where can i get a good service manual for this bike? any input or suggestions would be greatly appreciated.
