I recently adjusted my suspension and thought I would try SR's #'s they have on the web. At first, it fixed my rear wheel "slide" and I thought I was back in heavan. Now last night was only the second ride since I had changed it...

My problem, the bike does not want to lean into corners, no matter how hard I push on the clipon. It slightly leans over, then from there, its almost impossible to steer the bike without hanging off like a spider monkey.

If anyone has any suggested settings for a 190LB 6'2" rider, I am willing to try them out, before I just go tweaking the hell out of it.

My question is, what part of the suspension is keeping it so upright, or where should I start?

I assume you have a stock setup? If the bike is turning slow, that means that you have to much Rake &Trail up front. Did you adjust your Fork Height at all? How much Pre-load do you have in the rear?

My guess is that since you don't have a ride height adjustment, you don't have enought pre-load in the rear (I know it should only be used for sag but). You can try cranking up your preload to raise the rear some, which is going to take away some Trail from the front...

The only other thing you can do is raise the forks in the Triples a few Millimeters....

With your weight you are going to over-load the stock rear shock anyway so it is going to be hard to get correct sag in the rear, and still have the bike handle like it should...

Chime back with some more specifics of what you did to your bike and we might be able to help you more...

But it sounds like a Rake/Trail issue to me, more than likely due to a low rear end...

This is what I did...

front preload
3 lines showing (this may have been where I went wrong)

front rebound damping
7 clicks out

front comp. damping
9 clicks out

rear preload
position 8 of 9

rear rebound damping
21 clicks out

rear comp. damping
7 clicks out

These are numbers I got from sportrider, which at first I thought was good, till I took the bike to some moderate twisties, and realized I couldnt steer the bike. Your help is much appreciated, and yes, all stock suspension parts.

Ok..How many lines of Preload did you have before?

This is going to sound funny, but when you say position 8 of 9, is position 9 turned all the way to stop clockwise or counterclock wise? (I always do my Rear Preload measurement in mm :) )

The more clockwise you crank your rear preload, the more you are going to get, and the higher the rear is going to be...

I still believe that you have to much Rake and Trails, which tells me you more than likely took out some rear preload when you made your changes...

What was your preload front & rear before you changed?

Preload was like 4 lines showing up front, and rear preload was position 3 of 9 before.
Position 9 is all the way to stop, full stiff I suppose. When I had it before, my rear tire always felt like it was sliding out on me upon cornering.

Silly question, but is front preload the same as fork tube height above triple? Thanks again, Ive got to get this beast tweaked!

EDIT: changed "it" to rear preload ...

No front Preload is not the same as fork tube height...

To adjust your Forks you will need a front stand which lifts at the triple tree, you will losen all the clamps on the triple tress and slide the whole fork tube up or down in the tripple tree...

One line of front preload is not a drastic enough of a change to cause your issue...

But going from 3 in the rear to 8 in the rear is...

I still don't understand when you say "full stop"

Let's use counter-clock wise and clock wise...

To go from 3 to 8, you turned the preload...

a) 5 Turns Clockwise
b) 5 Tunrs Counter-Clockwise

FWIW, this is one of the hardest parts of suspension between people...Everyone has different "phrases" they like to use...

Typically when a person say "Full Stop" they are saying "Full Stop Clockwise"..

If that is the case, you have no rear preload, with 8 clicks of 9 from "Full Stop" so let's clarify what you mean when you say "Full Stop"

Is the answer "a" or "b"?

I am guessing "b" :thumbup

Actually, 5 turns clockwise.
:cryin

Guess this is going to be more difficult than I thought...

When I turn my Penske Clockwise I am adding Rear Pre-load...Sorry to say but I have always taken my Stock Shock off right when I get my bike so I can't for sure say how it works.. :lol

I would try going back 5 click counter-clockwise and see if that helps...

I am 100% convinced you have a Rake/Trail issue and w/o a height adjuster on your stock setup the only thing you could have fugged up was your Preload front/rear...

1 Line up front is not enought to cause your problems....

Go back to 8 of 9, and see if it fixes your turning issues...If it does see if you rear end push issue come back, if it does go down to 6 of 9, test again...

Yeah, I will try that. So rebound and compression damping wont come much into play with this scenario? Ill focus on preload for now... thanks for your time man!

The SR settings are prabably for someone lighter than you(140ish?).
Set your sag at 1 3/8 inch at the rear and 1 1/2 inch front.

Drop the front 5mm.....:thumbup
