Hi to all i am new to the forum . I have a question are there any differences between kr1 and kr1s pistons ? Cheers in advance
yes, but they are interchangeable. don't use original KR1 piston's !
goolge them and you'll spot the difference immediatly.
main differencen : ring-peg on S-piston's is covered by the rings who prevent if from comming out. KR1 rings go half under the peg, and the peg could come loose and hurt you cylinders badly.
