So Spring is here and I'm finally starting to ride again...I had my new Diablo Corsas installed last week and rode home in the rain... In preparation for the first "real" day of riding I've been able to do since last fall, I spent a few hours tinkering with suspension settings last night...I ended up with;

Front:
preload 9 turns out
rebound damping 3 turns out
compression damping 2 turns out

Rear:
preload 8 turns
rebound 2.5 turns
compression 2.5 turns

I have no one to help me set sag so....

I tip the scales at 250 with gear and am an aspiring commuter...

I went for an 80 miler today and had to stop halfway thru to check the vin and make sure this was really my bike...I don't know if it was the tire change(190 to 180) Pilot to Corsa or that combined with the new suspension settings, but it was like riding a new bike.

My ? for the all knowing amongst us is this; I am doing my first track school next weekend and am wondering if I should refine my settings and how? Any and all suggestions are welcome. TIA.

I can’t give you any advice on track settings since I haven’t been there yet, but I would try to find someone who can help you set your sag. Seems to me that the proper sag is the starting point of suspension settings. Although they usually recommend two helpers, I was able to set my sag with only the help of my wife.

:nod: Definitely find some help and set the sag properly - makes a big difference in handling and comfort.

I'm really excited for you - you are absolutely going to love having that bike out on the track! I'll ask my friends about tips re: the Spokane track on Monday and let you know what they have to say. :thumb:

fumb, w/o a respring of at least the forks (dunno about the stock shock on the 954), you will not get anywhere near the required range in sag up front. You're too heavy.

Check this thread for a similar discussion:

This is not to suggest you can't get to the track as is and have a ball. You just won't get the most out of your suspension as it is today.

Chain,
I see the forks being re-worked in my future probably the shock as well and definitely the gut...but not in the next week. I'm just wanting to get everything as near to good as posssible for now. Thanks for the link! Bwip, thanks, much appreciated! Any word on when you may wander north?

Also to note about the Corsa's...

They are around 10mm taller than a standard diablo/sportec in the front. This will slow your steering some. If you don't want it to slow, you should drop the front of the bike (ie, raise the forks in the tubes) 4-5mm to maintain stock geometry...

Or you could use it at stock height and enjoy a slightly more stable bike, at the expense of slower turn in... (given the nature of the 929/954, thats what I would do.)

Max out the preload. That's the best you'll be able to do with the stock springs, and have fun at your trackday!!
I believe HGT is referring to the front only. The back will prob be too much if you max it so I would go 2 less than max. The damping is your preference, hard/soft. Have fun at the track!

Yeah, good point, I was talking about the front only. Sorry. Yup, at least 2 less than max on the rear. What are there, 7 postions on the rear, I forget?

as with chains advice, you really should change those front springs.get a friend of equal or even less weight to sit on the bike and see how much is used up just in static sag, their designed for someone about 160 pounds and intermediate riding level.on the track they make the tyre do the suspension work, as a quick fix raise the oil level in the forks and max out the preload then half a turn of rebound to compensate for the added preload.
