Hi,

I was looking to get some help/advice with suspension set up and hoped someone on here might be able to point me in the right direction,
the suspension didn’t feel good so I took it to a local guy to set up for my weight and ability and he revalved and put correct shock spring for my weight.

it feels much better now but I am struggling in a few areas of the track and wondered if theses things are linked and what I should be doing or trying to resolve.

please note I’ve set up sag etc and dropped the forks through a little.

1. Acceleration chop feels very harsh front and back

2. I feel like I lack bite/traction with the front wheel when entering into turns

3. I have no confidence at all on sweeping turns with bumps either on entry or exit front end just feels loose

im a complete novice with suspension set up but have been trying to learn on YouTube and listening to keefer etc. so if anyone does any advice I’ll need in stupid persons terms lol

thank you in advance

You say you "dropped the forks." Do you mean you lowered the forks in the triple clamps, or did you lower the front end by raising the forks? That's an important distinction. Lowering the front end helps your corner entry and will increase your front-end traction feel. You must raise the forks a few mm to do this, however.

Also check your tire pressure. Running a high pressure always make my front tire feel skittish.

To answer all the questions so far (thanks for coming back to me)

The bike is a sxf 350 2012 so it’s getting on a bit now but I still enjoy riding it and it’s reliable so decided to keep it another year or 2 and get the suspension work done.

the sag on this model in the manual says  30mm/90mm and that sounded low so I have also tried 35/100 and 40/105 which is what seems to be standard for a lot of bikes.

I feel the 35/100 felt best but still having the issues

and yes I meant I have lowered the front end slightly instead of the top of the for being level with the triple clam they now stick above around 5mm as I read this helped with cornering,

im not sure what offerup is? 
thanks

If you had a local guy revalve it for you, you should ask him to come meet you at the track and watch you ride so he knows what changes need to be made.  If he’s like every other suspension shop I’ve ever dealt with, he will work with you until you are satisfied.  The first bike Factory Connection ever did for me was too soft.  When I told them, they revalved it again.  I told them it was still too soft, so they had me meet them out at Glen Helen and they watched me ride.  They revalved it at the track and it was perfect.  Now that they know what to do for me, every bike I’ve sent them since has been perfect on the first try.

Yep.  This is actually a huge selling point for having someone local do your stuff for you rather than sending it somewhere in the mail.

That 2012 should have the Closed Chamber forks right?  Those should be pretty damn good once set up correctly.

You’re are right but I don’t think that’s going to happen, whilst I think the guy I used really knows his stuff he does it on the side and works as a fitter full time and rides in his spare time, I expect if I paid more from one of the bigger shops here in the UK like KTech they may offer that but unfortunately I’m not going to get that from this guy,

Since you mention being somewhat of a novice...do you have a friend that is more experienced that could take a spin on your bike so that he can give his opinion? Problem with online advice is that there are so many factors coming into play that it's pretty difficult to get some solid advice on what should be done ...outside of setting your static and race sag.  Not saying this is the case but maybe even the way your riding the bike is contributing to the suspension not feeling right.

There are a lot of factors.  You already mentioned fork height, sag, springs, and valving.  These are all very important, but even the type of tires and amount of air pressure make a difference.  But the good news is that you can just learn as you go.  The best rule when trying to dial in suspension is to just do one thing at a time.  Don't change the forks and the shock all at once.  Don't change compression and rebound all at once.  The second rule is that you have to go fast to feel it, but don't go full blast.  You need to ride around 95% so you have enough control if something gets worse.  Charge, but don't ride at your limit.  Once you get it 90% good and want to just fine tune, then you can go all out.  The third rule is that you have to change enough to feel it, but not too much.  3-4 clicks should be noticeable.  1-2 is not enough and 5+ might just bee enough to end your day early.  Same with fork height or sag, 1mm change and you probably won't notice.  5+ mm might just be too much at once.  I also have to add, that I went through a LOT of suspension guys before I just paid the money for one of the best.  Enzo was my favorite.  PC and FC did some good stuff for me a few times too. Not sure what your options are over there, but it might be worth it next time.  

Does it feel harsh the first bump you hit?  If so, it might be stiff.  Open up compression 3-4 clicks on the shock, or fork, not both.  See how it feels.  If that it is better, do it some more.  Too much?...back it off.  If shock feels better, try fork.  

Does it feel plush at first and then get harsh?  If so, then you likely have rebound too slow and the suspension is packing up and then reacting.  If this is the case, then open up the rebound 3-4 clicks and see how it feels. 

For the fork, does it continue to get lower as you charge into a corner?  This can be both compression or rebound....probably a little of both.  But start with rebound and then add in some compression as you continue to ride.  If it deflects when you hit the first breaking bump, go the other way.  

For the shock, does it feel good in a rut, but get worse?  Does the seat continue to get lower as you accelerate out of a corner and then just start bouncing?  Then probably rebound, and a little compression too.  Start with rebound and speed it up.  Then add in a little compression.  

If you are going through whoops and it feels good at first, but then the rear starts to dance side to side, you are too slow on rebound.  You might also be a little too soft, as compression and rebound both affect each other some.  But start with one or the other, not both at the same time.  

As track conditions change, the pros make changes to their bikes.  But if you ride the same setup all the time, you can lear how it is going to react and adjust your riding style.  And sometimes, maybe you just need to go faster.  That's what I was told when I was complaining about my suspension in the whoops one year.....  "You are going too slow.  Go faster and it will work better."  Thanks Dad.  But, he was right.
