Title: raising the rear
Post by: jeremy_nash on March 03, 2009, 09:58:53 PM
I've searched, and couldn't find the answer too my exact question.  I want to raise the rear of my bike, like around 2 inches or so,  but  dont want to have a harsh ride.  the only raising links I can find are 1 1/4 inches.  is there a longer shock that wont ride much harder?  I currently run my stock shock at 4, and it rides comfortably   thanks

The SV shock... i've got one all set to bolt straight in if you want it... i only recommend that you upgrade the front end springs with it... cuz it's kinda "divey" in turns and under hard braking.

PM me.

how much will it raise my bike?  I  dont want it to ride hard, just a little taller.  if I could find raising dogbones in a 2 or 2.5 inch, that would be perfect.  what kind of adjustments are there on the sv shock?  have you ridden on it in your gs? was it harder?

These people have links in about any length you might need:

http://burkhartcycle.com/store/index.php?main_page=product_info&cPath=24_28&products_id=73

Stock links are about 7 1/16" between hole centers and the ratio of change is about 5:1 on the GS.  I put on links that were 1/4" longer than stock and it lowered the bike about 1 1/4".

I discovered these links after I bought some Pingel links from Dennis Kirk for about 3 times the price of these Burkhartcycle links so I haven't tried this brand myself yet.

Those are cool. I would worry about vibration loosening the lock nut over time if not checked. Wished I saw these before I ordered my links.

Ok I changed my 07 500 stock shock to 7 setting...I like it, pretty stiff enough...so I'll probably pass on the Kat shock upgrade for now since I'm sure it will feel the same...except that the Kat shock will raise..............SO shorter dogbones I want to do, to still raise the rear end....I went on www.burkhartcycle.com....they only have LOWERING links for GS500...unless someone can tell me where to look for RAISING links???

Are the shorter dogbones being sold on eBay trustworthy?
http://cgi.ebay.ca/Raising-Riser-kit-GS500-GS-500-All-Years_W0QQitemZ280276836501QQcmdZViewItemQQptZMotorcycles_Parts_Accessories?hash=item280276836501&_trksid=p3286.c0.m14&_trkparms=72%3A1215|66%3A2|65%3A12|39%3A1|240%3A1318

But they only raise 1.25 inches...will it be a noticable difference...both visually and when sitting on the bike???


P.S. Yea those adjustable links are very smart design, watch the installation video, I love them! But a bit pricey

Post by: gsJack on March 07, 2009, 08:15:50 PM
Like I said above, the stock links are 7 1/16" long.  The links longer than that will lower and the ones shorter than that will raise it up.

OH you mean that page I can select my own length...ok so which length will raise it by 2inches??? Appreciate your help
Title: Re: raising the rear
Post by: gsJack on March 08, 2009, 06:58:21 AM
It's about 5:1 ratio so for 2" higher you'd want about 2/5 = .4" shorter.

7 1/16 = 7.06 - .4 = 6.66 approx.  I'd try the 6.660 long ones for about 2" higher.

I put on 7 5/16" links and got 1 1/4" lower and another poster reported 1 3/8" lower for 7 5/16" links so the 5:1 ratio seems about right.
Title: Re: raising the rear
Post by: vorBH on March 08, 2009, 08:37:57 AM
Awesome!!...but question...I don't know whether if I want it up 2inches or 3inches......what is a way to get a feeling...put a 2 or 3 inch block of wood under the rear tire?? Will that give the feeling of a 2 or 3 inch raised bike?
Title: Re: raising the rear
Post by: vorBH on March 08, 2009, 09:42:02 PM
Guys, does the front end need be worked on if increase rear end by 2.5inches?
I am aware of the 'diving' situation with a higher rear end........BUT if I get shorter dogbones/links that'll raise the rearend by 2.5inches.....will I need to do some work on the front end to make them fit??
Title: Re: raising the rear
Post by: vorBH on March 11, 2009, 12:46:54 PM
I emailed http://www.burkhartcycle.com/Site/extras/linktable.htm regarding a 2inch raise.

They said:
QuoteI'll take a closer look at it, but I'm not sure if that much lift is a good idea. Had you swapped out the shock or anything that lowered the rear?

So is it a problem if I get 6.660 length dogbones to raise the rear end?

Very good numbers. From eyeball many years ago I calculated 1 to 4 for linkage and 1:2 for shock. The thing is a slightly longer set of dogbones, you wont even notice. Till you put it on.
Cool.

So do you think 6.660 will be safe for about 2inches higher?
Title: Re: raising the rear
Post by: bill14224 on March 11, 2009, 04:11:25 PM
Before you jack up your ass end, remember it'll put more load on the front end, change your steering geometry, (it'll steer even quicker) and you'll lose rear wheel traction easier unless you use a softer rear spring setting than you normally would, go to softer rear tire compound, or both.

Our bike doesn't lack rear travel or ride height.  I don't understand the desire to increase it.  Looks?  :dunno_black:
Title: Re: raising the rear
Post by: vorBH on March 11, 2009, 05:33:43 PM
Actually, it is kinda on the lowside (I find)....I was riding a cbr125 just before it, now got the 500....and the 125 is way more comfortable for the legs....the 500 is more cramped and what not
The riser kit wont make a huuuuge difference, but its also for looks and the minor improvement, if any

I put a 1.5 inch tall piece wood under rear tire to simulate and it felt better, it needs that 1 or 2 inch raise I found...kind of feels like I'm falling backward in stock height...even on 7 stock shock setting...But I guess everyone has their own preferences! :)

You raise up the rear, the bike will go faster, always, run better gas mileage and really accelerate better.
Cos you're going downhill all the time ...  O0

Post by: gsJack on March 11, 2009, 08:52:53 PM
After wearing out the oem Excedra tires and a pair of 1st generation oem size BT45s I put a couple of 130/90 size rear tires on my 97 GS. These 130/90 touring tires were a full 2" larger in diameter than the 130/70 oem and raised the rear of the bike 1".  The steering was noticeably quicker and I liked it that way.  The front was completely stock, I added my Progressive springs after the 130/90 tires were used up.  I had no problems with the handling due to that 1" rise in the rear.  The 1st 130/90 was a Metz ME88 and it handled about as well as the early BT45 but the 2nd was a Dunlop K491 and it just didn't want to go around corners as fast as the GS did.  I went to some sport touring radials after that.

Lol, I'll look out for that after the mod!

Wait...the stock height of the wheel is 70....will 90 height of the tire raise the bike up in the back?? (ie 130/90)
Because I need to get tires soon and I don't know what to get...
Title: Re: raising the rear
Post by: gsJack on March 12, 2009, 07:11:35 AM
Yes, they all vary a bit but a 140/70 will raise it about 1/4", a 130/80 or 150/70 will raise it about 1/2", a 140/80 about 3/4", and a 130/90 about 1".  Could be a taller tire and only 1" lowering links would give you what you want.
Title: Re: raising the rear
Post by: vorBH on April 01, 2009, 10:17:35 AM
Ok got a problem....I'm getting word that the raising links found on eBay or any raising links don't work on the GS...since it will lift it up and cause the swingarm to hit something and what not....I don't know the details.

Can someone who has put the raising links on a stock shock GS500 confirm that it works? Couple people would be good.....I have the raising liinks ready to put on, but its better to find out this way if they are not going to workout.....but I imagine that they will....appreciate the help
Title: Re: raising the rear
Post by: The Buddha on April 01, 2009, 10:36:50 AM
Yes it will hit the swingarm ... shock hits swingarm. Grind up the swingarm if its not too bad.
Cool.
Buddha.
Title: Re: raising the rear
Post by: vorBH on April 01, 2009, 10:47:12 AM
Hmmm What is it exactly that hits the swingarm?

If you could explain what happens when the bike gets liffted 1.25inches...thanks man
Title: Re: raising the rear
Post by: The Buddha on April 01, 2009, 10:52:29 AM
The linkage actually points toward the rear wheel's contact patch. Shorter dog bone makes it point toward the sprocket. It moves it up. That since the linkage has to be the same length as stock will shove the bottom part of the shock toward the back, and that = clink with the swingarm. The spring of the shock hits the back side of that hole in the swingarm on the bottom.
I would however think that you could run that with stock shock, or run just a longer shock, and not do both. Personally I prefer shock ...
Cool.

Quotebottom part of the shock toward the back, and that = clink with the swingarm. The spring of the shock hits the back side of that hole in the swingarm on the bottom.

Hmm Ok, so which part would I have to shave? And how much to shave off...and is this safe to shave off frame metal?
Title: Re: raising the rear
Post by: joshr08 on April 01, 2009, 11:24:02 AM
i personally would go kat shock and taller rear tire over grinding the swingarm and sticking with the stock junk gs shock :thumb:

Its prolly safe ... but hey, its your bike not mine, so let me go on a limp here and say its very safe, in fact it may be unsafe to not do it. Bwaaaaaa ...
Dude, that part is plenty thick, however its not easy to access without taking 1/2 the bike to bits. I'd infact take the swingarm and invert it and grind up the right spot if someone had a gun to my head.
Just swap shocks like joshr08 said.
Cool.

Title: Re: raising the rear
Post by: vorBH on April 01, 2009, 11:41:32 AM
Ok cool....last question tho.....if the Kat shock also raises the bike....why doesn't this problem exist when you install a Kat shock?
Title: Re: raising the rear
Post by: joshr08 on April 01, 2009, 11:47:57 AM
because your not shortening your dog bone so its not pulling the shock in. it stays at the same distance out from the swingarm. 

side note.  i used to run my gs shock on 7 so it felt ok to me now with the kat750 buddha suppled shock im running it on 4 and as far as ride it feels pretty close to the stiffness of the gs set on 7 but with the adjustablity to fine tune it for riding style.
Title: Re: raising the rear
Post by: vorBH on April 01, 2009, 11:52:53 AM
Perfect, thats just the info I needed....so I'll keep the shock at 7 as I have it right now....dogbones an issue though
Title: Re: raising the rear
Post by: joshr08 on April 01, 2009, 11:56:41 AM
are you missing the point where the kat shock is better and raises the bike 1 1/4 inches and then with a 1 taller tire you get your 2 inches or a bit more of lift without grinding anything and getting rid of the crap gs shock.  unless your 220+ you shouldnt have to run your shock on 7 for preload
Title: Re: raising the rear
Post by: vorBH on April 01, 2009, 12:02:09 PM
lol no I get it....but changing the shock is such a hassle...well in the GSXR and SV650 shock upgrade case.

But the Kat shock is just bolt on right?....so easier, hmmm I guess I would reconsider changing to the Kat750 shock
Title: Re: raising the rear
Post by: joshr08 on April 01, 2009, 12:04:52 PM
lets just say when i did mine i was also doing the carbs so it too 3 mins that included taking old shock out and dropping kat shock right down through the air box opening.
Title: Re: raising the rear
Post by: vorBH on April 01, 2009, 12:06:21 PM
Awesome so just bolt in and go right?
I sent Budda an email for kat750 shock
Title: Re: raising the rear
Post by: joshr08 on April 01, 2009, 12:08:06 PM
bolt in and go now my shock was super easy to line up because i didnt have the rear tire weight to deal with but it shouldnt be bad if someone can just move it or hold it while you bolt it up
Title: Re: raising the rear
Post by: vorBH on April 01, 2009, 12:11:36 PM
Ok thanks for your help man, you've helped me to make a quick turnaround on what I was going to do about raising the stiffness of the shock and height of rear
Title: Re: raising the rear
Post by: joshr08 on April 01, 2009, 12:14:40 PM
if you look at my pics of my bike its got a kat 750 rear shock but 160/60 rear tire and i used to touch flat footed with gs shock and stock tires and im not so flat footed anymore with the new tire and new shock  and its not set anywhere close to as stiff as the ol gs shock was.  i really think kat shock and taller tire will get you more of what you want with less headaches

GSXR 90-95 750 and 91-98 1100 does fit ... but yes linkage has to be shaved. I am out ... I need all the cores back.
SV650 - forget it its not even close.
Kat 6/7's fit like the proverbial glove.
