geezas Ji107 bad idea mate,don't grind the tip,when you push/press it back through the sideplate it expands & locks itself!!(usually don't have to spread/peenover with punch thatway!),i use steel plate with predrilled holes,one shallow locating the pin you leave alone,the other a predetermined depth where the pin disengages from the centre roller,but remains in the sideplate,twist the camchain sideways to release ,remove links you don't want, realign,punch back together,simple,done it that way forever,wait till you try & shorten morse (hyvo),tip, don't drink before attempting
,
ps GD,DID gokart chains lighter than tsubaki,but it's dogbone,harsh on std tensioner system,(if yer running that
)
