they was this style of circlip http://www.ebay.co.uk/itm/MZ-NEW-PI...47?pt=UK_Motorcycle_Parts&hash=item3efc1e6a93 just fitted it like any other one ive fitted with the bits that sqeeze together pointing forwards
Never buy them ,,,cos Wat happens as the gudhin pin moves an spins it will wear at them and eventually snap them ...I learnt that couple week ago ...buy the full circle ones and also when you fit them fit them facing up or down not at an angle cos with every rotation of the crank they will bend and it's will eventually get loose and ping out
they came with the piston and i had no others to fit but either way they shouldnt have failed after 20 miles all i can think of is it wasnt a flat clip and its caught the port and pulled it out.
yeh but i did some looking on the net and there not chinese there tiawanese compleatly different quality. i emailed the company i got the piston kit from and they couldnt say sorry enough and have sent me free of charge a new piston and barrel kit. I wont be fitting it but always handy to have a spare lying around
