New tires....
 

dont ya just love the way your bike feels with a new set of tires

got my wheels and new Pirelli Diablo Corsa III's in the truck to get them put on tomorrow, now just gotta get some warm weather to ride...

Yep! I have a new set of tires just waiting to be put on! :D

(need new job first...)

thing is we put motorcycle tires on at my work, but its still cheaper for me to have someone else do it.....that blows, my boss will let me change them there for $12 each, but my buddy that owns his own bike shop only charges $10, he's even picking them up at my job and bringing them back to me, cant beat that, and its not just cause we're friends, he charges everybody $10 a tire

Wait... you would get charged to do the work yourself?? How does that work?

And I don't always love the feel of new tires. The new PP's were WAY too twitchy for the street on my 1125. After about 500 miles of highway driving/commuting, they were much better.
Loved the feel of my Corsa III's... just wish I could get more than 3K out of a set...

tell me about it, guess cause i'm using his machine and his time, it pisses me off, that s why i dont even bother, just take em somewhere else

Can't you do it after hours? I forget where you work, so :idk:

Gotta love having to pay your boss for "YOUR TIME!" (insert rolley eyes here) Isn't there some way that you could do them on your lunch break or something?? Seems shitty to me.

dont wanna even bother asking , would rather just give our buddy $20 anyway

I understand 100% ;) I probably wouldn't get mine for free, but I help out and on occassion, do them myself. :D I try to help him out on the weekends when he needs it and do other things too. I guess I kind of pay for it, but in the long run.......what are friends for? :)

Your boss sucks.



And I think I might go back to Pilot Powers when the DC III's wear out.

I warn you, be cautious on the first ride.
The fast turn/tip in that everyone loves with them on a Jap bike = super twitchyness on a Buell for the first miles. (at least on the 1125)

If you set-up your suspension you can tune-out the twitchiness.

and then i lose the quick turn in once the tires wear a bit.

a week of commuting took care of the problem just as well.

But yeah, I know your point. I just really don't know enough about suspension to be fucking around with it a lot myself.

Then learn. :idk:

Write down your stock settings (count the number of clicks from where it is to the stop for both rebound and compression, and write down what your pre-load is set at) and screw with it. If you mess it up too bad you can always go back to stock and start over. You'd be amazed what a few clicks here or there can do for your suspension.

Maybe at my next track day. tough to tell what it's doing when all you have is straight and flat.

I feel yeah on the "straight and flat"

I don't have time right now, but google "sag" and set that first (it's easy) and then mess with your compression and rebound. Even if you totally screw it up BAD it's not going to be bad enough to make you wreck (unless you're pushing, hard). My recommendation? Fine an industrial park or something with a few twists and use it as a test-track for your suspension. Make changes, ride, make more etc.

Sag has been set... it's the fine tuning stuff I haven't played with. To some extent trying to get used to having "good" suspension after the SV's preload only adjustment.

I had no idea, but I have wondered if there was supposed to be some sort of adjustment for this. Thanks for the learning man. ;)

Here to help! That's why I'm a ridercoach.

;)

Hey speaking of that...do you use a partner or do you use a sag measurement kit like this one...

I use a few buddies to help, I don't want to be your "partner" :lol:

The problem is you need to measure sag to include when the suspension is completely unloaded, as in rear tire is off the ground. If you want to do that on your own it's kind of a bitch unless you have special stands.

Yea but you only have to measure that once and really,isn't that number in the service manual under "suspension travel"? I mean that number is never going to change right? The numbers you really need to get are when the bike is alone vs with a rider. Can't you get those using stands?

I'm trying something other than Pilot Powers. I'm getting some Bridgestone BTO16s mounted to my black wheels which are currently being pinstriped. A couple of buddies won't shut up about how nice they are, so I'm giving 'em a shot.

It's a LOT more complicated than that. You are figuring out how much your suspension compresses under the weight it is supporting, that includes the weight of the bike and the rider (and gear! you'd be amazed how many people measure sag in basketball shorts and a t-shirt not taking into account how much leathers weigh). "Suspension Travel" in your owners manual is the distance from full compression to full extension, it doesn't take into account the amount your suspension settles under the weight of the bike. And because the suspension is supporting that weight you need to take it into account in your adjustments.

Hmmm yea but didn't you say you lift the bike until the tire is off the ground? That's full extension and the shock/fork's design will only allow it to go so far... Shoot,I thought I understood this shit! I take the max extension number for granted and adjust preload based on the bike alone vs bike with rider numbers...

I'm using the BT-016s right now...the jury is still out-I REALLY liked my Pirellis!

We shall see. I'll be going to my favorite spot on Sunday to break 'em in.

I like the Corsa's...and they are wearing pretty nicely. But I loved the Pilot Powers. So I figure I'll run a set and see whats what.

The XB might even have sharper geometry than the 1125. Not sure on that.

yeah the corsa IIIs are lovely, I tried the PP 2CTs and to be honest I prefer the regular PPs to them.

Really? How come. I was gonna go with the 2CT's.

Sport rider gave the 2cts the highest ranking out of the different brands they tested, over the dcIII, bt-016, contisport attack and a few others. The test was based around tires that can be used street and track.

Correct, but you have to find out how much of that travel is being used by the bikes static weight, and then again with the weight of the rider/gear on the bike.

Wait...that made sense somehow...

Yeah I read that too.

No prob :D

:lol

That's exactly what I said. Without lifting the bike you don't know how much the weight of the bike compresses the suspension.

Anyway, glad you got your answer.

Dude is on a roll today.

So,

g_{\mu \nu} = \eta_{\mu \nu} + fk_{\mu}k_{\nu} \!.

f = \frac{Gr^2}{r^4 + a^2z^2}\left[2Mr - Q^2 \right].

k_{x} = \frac{rx+ay}{r^2 + a^2}..

k_{y} = \frac{ry-ax}{r^2 + a^2}..

k_{z} = \frac{z}{r}..

k_{0} = 1.

And (with "r" being my weight with gear,

1 = \frac{x^2+y^2}{r^2 + a^2} + \frac{z^2}{r^2}

Taking into account,

A_{\mu} = \frac{Qr^3}{r^4 + a^2z^2}k_{\mu}

\vec{E} + i\vec{B} = -\vec{\nabla}\Omega\,

\Omega = \frac{Q}{\sqrt{(\vec{R}-i\vec{a})^2}} \,

with my weight of 275 lbs means that I need to add one line of pre-load on my front forks and subtract two threads on my shock.

Thanks,Guys!!!:dthumb:

Fuck....that gave me a headache... :?:

LOL What she said. :D

I was told on svrider by a few peeps that at my weight and my riding style, the stock set up on my bike is good. I still have a gix shock I was going to put on it, but fuck it....I'm not messing with it. :lol:

Bummer.

I agree, the GSXR shock is great for heavier riders and trackheads but for you I'd say if it aint broke don't fix it.

I've ridden an SV with the Gix shock and noticed a small difference but didn't ride it enough to say if it was better or at least have enough improvement for me to do the swap. Besides, it's a PITA to do...and since I didn't notice an immediate remarkable difference, I decided not to do it.

However....I've messed around with the preload on the rear shock a bit but put her back to where she was stock.

I also messed around a bit with the preload on the forks as well as put in a heavier weight fork oil. Doing that seemed to help with the way she handles on the rough roads we have here.

I'm satisfied with the way I have her set up now. :)

I almost ate it on my BTO16s. I wasn't even doing anything crazy, just pulling the bike away from the durb and turning around and right back in the garage. It doesn't help my street is dusty as fuck right now either.

Are they "broke in" at all? Mine are ok but they definitely aren't "out of the garage" ready like my Pirellis were...:panic: You got to warm these bitches up some...

Hell no. They had about 20 feet on them at that point.

20 feet. Nice.

Yea...I told you the story about an idiot who bought his bike in Nov and decided to take it out the day after Thanksgiving on cold Bridgestone tires when he was used to Pirellis....

"Hello State Farm...remember that bike I insured 4 days ago? Well.....":panic:

It was because my street was dusty as fuck. I just took them out on the highway for a bit and we have a real nice 130mph curve on an onramp. They handled it nicely. The spirited ride comes tomorrow...if I don't drink too much tonight.

Well just please take it easy,Bro. Hy did you see my post about Michelin race tires? Good deal there!
