Hello I've recently bought a cr125 , I was on it and it seemed abit flat and then I changed the spark plug it went like a bad out of hell for about 15 mins then it stopped when I was going really slow went to start it and it wouldn't start on the kick only backfired after about 10 . It bump started and I ride home however now it won't kick start it only backfires after a few kicks ? It will start on a bump to make sure the fire triangle is there !

I was talking of the head to see if the rings had gone while there I was training the coolant to my surprise nothing came out ,out a drop in and it leaked out a small hole under the casing behind the water pump turbine it couldn't have mixed with the oil ?

Ino I'll need a water pump seal and bearing but what else will I need to set this bike right ?

You'd be well served to check all the basics. Pull and measure the cylinder, check the rod and crank for wear, measure the piston and rings, check the reeds etc. With a used bike it's best to assume everything is worn out until you measure and prove otherwise.
