I need a good shims stacks combo for SACHS on ec 300 2010
 

I recently bought an EC 300 2010 six days ,super good condition. My fear is the suspension,forks more exactly .
Would be nice to have Marzocchi&Ohlins but I hope to find good revalving combo.

I have 75kg without gear.

I will pick up the bike Saturday,I don't know nothing about spring numbers.

So,is worth to revalv those SACHS forks or to find some KYB,SOWA,WP?
