I know there has been lots of input about changing rear shock ,just wondering has anyone fitted a wilbers 640 shock,maxton , ohlins ,nitron seem to be the most popular ,looking to upgrade but not sure which one to go for ,also has anyone found benefit fom changing springs and oil in forks or does it need to be cartridge internals to make any benefit,just picked up 6mth old mt last week ,front is like a pogo then rear unsettles over bumps and pushes front even more giving a very unsettled feeling ,bike is on std settings can mess about with settings but most seem to change shock,have a wilbers in lc350 like a new bike thinkin of wilbers for mt just want to see if anyone has it in mt.
