So after reading thoughts about how to gain more performance, I've decided to go with suspension upgrades instead of motor upgrades for my 9Sl.

I'd like to add the 1125r's brakes, but am curious as to what you guys are running for aftermarket suspensions...front end especially. Even with proper suspension setup and new rubber, I still get the Nervous Nellies and twitching in the front end...ideas? I'm not opposed to spending money on new forks if need be.

That is an excellent idea Steve, thanks.

+1 on suspension

Also, how about a double ZTL2 front wheel? Add that to an improved suspension and that will be a fast in and out of the corner XB.

You can always add a 88" kit later.

No doubt about improved suspension vs. horsepower.

But gettin' your suspension tuned to your riding style and physical reference is worth more than fancy new forks. I would first try to find the 'sweet spot' with what ya have first. I am unsure of the 9SL, but the 12scg actually had a smaller outdated set of forks and rear shock on them. My STT came the newer SHOWA's. I added some chamber inserts with progessive springs and top-outs. I changed my oil to 15W and they fit my attributes perfectly! All the stuff I put in, we had laying around the shop.
Any questions, I spent too much time rebuilding my dirtbike suspension to not know a few tricks.

The steering shake is common on all the XBs and XBr models. lots have tried stabilizers. I am a huge fan of GPR and have a decent knowledge and catalog of stuff to look through. The setups get pricey - 300-500 dollars.

(I copied an earlier post I had) - Besides the steering stabilizer, also look into changing the egros of the bike. Some actually believe that the trail of the bike is actually the culprit. They even sell a kit for your bike on trojan-horse. I believe this is the direct link:
http://www.trojan-horse.co.uk/prods/148.html

I have a a different trail and it made a difference. I have had head shake one time on my bike. Pulled a second gear leaner on an exit ramp. Wheel came down with a TON of right input. Throttled right out of it, maybe two shakes. Just something to think about.

Any Question feel free to ask . . . forks can be done relatively cheap!

Look into the Traxxion AK-20 gas cartridges.

Better response. The Rossmeyer MotoST bike uses them. Bilansky has used them so IF they offer benefits, he'd be able to set you straight.

I haven't run my AK-20 modified forks yet but have had friends in CMRA who race GSXRs and after putting in AK-20 modified forks, they ditched the Ohlins.

I had Henry send Max (Mr. Traxxion Dynamics) a set of race only forks and Max did the complete front end rebuild (valving, springs and AK-20) - when I upgraded the 03 from 41mm to 43mm forks)

Max and Dan are really responsive to email and phone through the Traxxion.com website.

Traxxion has been working Buell racing suspensions since the earliest days.

Bilansky can give you a good opinion on whether it's worth the extra $$$

The heavy rotor (from Duga/Buell Racing) and 1125 caliper ought to give you a more braking-capable system for endurance-type racing. Willow Springs where I end up doing most of my racing just doesn't require a lot of braking since there are such long high-speed sections between the heavy braking - so you get such good brake cooling.

Just my $0.02 - worth half of what you paid for it

Oh and check the rules for racing - 88 cubic inches will not be allowed in almost any race class. If you're NOT racing, it's not a biggie. Cubic inches are a better way to get HP than bumping up compression.


On the motor thing:
If you're opening up the motor anyways, consider upgrading to the 2008 crank.

The motor mods start getting pricey

Yeah, just price out an '08 lightened/balanced crank assembly from Hals.

But I suggest EVERYONE buy one.... Since I get paid to do all the lightening on them : )

And before anyone asks, no I wont tell you what goes in to it, and no, I wont do it for you : )

Not to hijack here but I have a few questions about the 2008 crank.

Where is the material being removed off the crank? Were the rods also lightened? Pistons? Was the 12 crank the only one that was lightened or the 9 also?

Speedfreak, Since Hals HD/Buell is my customer in this respect, I can't comment on WHAT I do for them. I value my relationship with them in this respect, and what THEY do to the crank assembly is *THEIR* proprietary info that I wont give out. Sorry I can't be of more help. But to get the answers to your questions, I'd suggest calling their speed shop at:
262-814-8661
Tell Sam I sent ya : )

I understand what you are doing is proprietary and not to be disclosed.

If I understood the post by Slaughter correctly then there is a difference in the 2008 crank vs the previous years. That is where my questions apply. So what has BUELL done to their cranks.

thanks,
Bart

"And before anyone asks, no I wont tell you what goes in to it, and no, I wont do it for you"

How's about some sliders Steve!??!!

Let me ask this. Would the newer Scg forks slip on to my Sl?

yes, the scg forks and low forks share the same dimensions. In fact I'm not aware of any
changes between the 2 models.

Not having actually SEEN an 08 crank, I can only repeat what I've been told - that the main pin is larger. (therefore stronger, more rigid). I think this is the primary reason that the 2008 redlines are set higher than previous years... and I went and ordered the 08 crankset for my resurrection.

Spinning these motors faster and hitting the rev limit a lot is really hard on their bottom ends.

I think I'm going to try adding 2° to the rake and increase the fork size from 41 to 43mm.

Has anybody tried a front tire that's a little larger? Would that help or hurt?
