Ok here comes the fun part.I just pulled the head on my 95 raider 1100.The top of the pistons are stamped with KD and two numbers.Does anybody know if kd is a aftermarket piston.If it is is kd the name of the company that makes the piston or is it another company and they just stamp kd on it?Just want to try and find out what this has been bored out to (if it was)so i know what i have.The other thing is does anybody have pics of there pistons(tops)on a properly adjusted machine just want to compare to mine and see how it was running.
