It has an Ohlins rear shock (or maybe just an Ohlins sticker) and WP forks, whatever the fook they are?
Is there like a chart or something that shows how many ideal clicks/turns = rider's weight?
I know I sound vague but haven't got it long and had major surgery of late and haven't done much poking around with it
suspension is easily the most important aspect of a bikes handling. it will def have an effect on stability. however, head shake is still going to be there to a degree.
brother id love to just feed you my settings so you could simply go out n plug them in but unfortunately it doesnt work that way.
the thing is suspension operates differently for each and every bike depending on several factor unique to your specific bike. i dont mean model, but literally your bike. things like oil level, oil condition, bushing and seal condition etc etc.
ill go on to say setting up suspension is a very hard thing to really tell someone how to do. its a bit of a black art really. something all the reading in the world wont make you good at. it involves a fair amount of experience to be good.
the basic idea is you want it even front to back. even going down and even coming up. if its off front to back youd really be surprised how much it affects handling.
my best advice is get your bike to someone who knows how to do a setup. the good news is for an experienced suspension technician this is an easy 30 minute job. its cheap to have it done for you. i understand everyone doesnt have a suspension tech in their town but itd be worth a drive to one.
call a few shops close to you and inquire about some help with a suspension setup. see what they say, chances are if they cant help you they will know where you can find someone and usually within any local mc community there are one or two that everyone uses. so id ask around n see where people point you. then id go see them. if youre interested in learning ask for a guided tour while they set you up.
suspension is like a chain in its only as good as its weakest link. rear shocks hold up much better than forks because they are more of a closed system. so a suspension setup consists of getting the forks to the best setting they can be for the condition they are currently in and of course with you the rider using them. then the rear is tweaked to match the front as best it can.
you asked about the damper. ill tell you with 100% certainty that your best investment, and one you should def spend money on before you buy a damper would be getting proper springs for your weight in the forks. those arent crazy expensive. youll need a few other things with them tho. obviously to get the springs in the forks gotta be taken apart and this is the time to replace the seals and oil. you can buy springs and all the parts to freshen the forks for about 200$, give or take and itll be another 150 or so to pay a good tech to do them. whoever you find that can do that job around you is likely the same one who can setup your suspension as well. id call a few places n get as many opinions as you can get n go with whoever is recommended the most. just because a shop can do the job doesnt mean they are going to be the best at it. do some research.
this would be by far the best money you can spend on your bike. period. if you dont have the money to drop on a 700$ rear shock there isnt a real need to revalve the front forks. remember suspension is only as good as its weakest link. the rear shock can cover a broader range than the front end so a good set of springs and fresh oil n seals is all you really need up front until you do think your ready to go to that next level n buy an aftermarket rear shock. then doing the valve upgrade would be justifiable.
