for GS550 owners only (80-82)

[first timer]

as promised all the info i have on getting as much power from the gs550 as you can...

http://www.macperformance.com/ give them a call directly and they can swap stock baffles for competition baffles (1.5?) at no extra cost. You can check out the pics at http://www.macprod.orc.ca/


Rear sets http://www.discovolantemoto.com/firstpage.html

A Jet kit from http://www.dynojet.com for a SUZ 82 GS550 KATANA part number 3314 will fit your bike if you have the bs32cv carbs on your bike
You could also call k and n and see if they have any extra jet kits for the above mentioned bike available for sale since they are currently having a clearance sale on jet kits. This is the current kit I have on my bike and it works fine.

You will also need to order k and n filters part number rc-2382 I found http://www.martelbros.com had the best price and shipping is free, you just need to order one set or 1 box I mean since 2 filters come per box and each filter goes on 2 carbs.

o-rings for carbs http://home.att.net/~robert.barr/#Outside%20of%20the

good prices on tires http://www.ronayers.com/ I had the Bridgestone spit fires and they were ok but now have some pirelli sport demons and these by far are the best sport tire for these bikes

good article on degreeing your cams here http://medlem.spray.se/biker66/index.html under ?my modifications? ?cam timing? very well done biker66

there is a 650 top end coversion that has been done ask Nerobro

I have also seen braided steel brake lines for our bikes but don't know where they are off hand.


There are also articles achieved in the GSR on how to make your own too lean / too rich sensor for your bike using a oxygen sensor

Other then that, thats all the info I have on making a 550 faster and the only stuff that have done to my bike to make it faster and has worked with minor problems are the jet kit, exhaust and coils, I plan on degreeing the cams this winter.

First Timer,

WOW!!! Let me say that again WOW!!!

What an awesomely, detailed and helpful post!! It is extremely cool of you to go through all that trouble for me... Thanks!!

You have given me a huge head start, in getting my bike to where I want it to be. Thanks! This winter I am going to tare my bike down, and strip, clean, paint, buff, and refinish every last part, nut, and bolt. I have already bought just about everything I need so far. Once I figure out which carb I have I will be able to decide whether or not to jet etc.

thanks again
Van

these are the carbs (CV) that the jet kit i told you about will work for

ryan

[AOD]

yes, you have Mikuni 22mm CV (constant velocity) carbs. used on GS's from 80-86.

Adam,

sorry that i have to ask this, but "yes" what? yes the jetting kit that Ryan mentioned will work on my carb, or "yes" to something else.

sorry

Van

[first timer]

van, if you have the above pictured carbs, then yes you can run the jet kit i told you about. the above carbs are the CV (constant velocity) bs32 carbs. which i believe is what adam is trying to tell you. i compared all the oem jets and stuff of the 80-82 cv carbs. they all use the same stuff. they only have the gs550 mz kat model listed for jet kits because that was the sport model but all 550's that have cv bs 32 carbs have the same stuff so you will have no problem running a jet kit. just make sure you don't cut corners and get cheap air filters, you have to get the ones i mentioned above in order for it to run right.l

Van, you said you didn't know what kind of carbs you had...so we are telling you!

K&N DID have a jet kit for my bike.. like $40 with shipping!! not bad compared to the $150 the other place wanted. i also bought the filter.

I have questions about the exhaust though..

Adam has a kerker
Ryan a Mac
Robben a jardine

why did you guys choose the ones you did?

i searched around and didnt find any conclusive statement labeling any one brand or style/type as the best choice.

i will continue searching around, but any input from ya'll would be great..

thanks again
Van

Jardine for me, because the dealer (a trusted one) said it was the only one available in his catalogs for my bike. I didn't use online purchasing because most are US based, and with the exchange rates, and broker fees, it can end up costing more. As it is, I have to suffer with a chrome setup. I wanted black. Thus is the schtick of living in eastern Canada, sometimes.

I go online to buy when it just isn't available here.

Robben

'member when I told you you'd get more info than you'd ever need?? Now do you believe me? Sometimes, you just need a little patience. 8)

it is a virtue ;-)

thanks Robben

No problem. Looks to me like you've got a busy winter planned ahead. 8O Just remember to have fun, and come up for air once in awhile.

Hi,

I've got an '80 GS550L which has been almost stock from the time I bought it (1989) 'til now. I say almost because the guy who owned it before me said he drilled out the baffles to make it louder (which it is ... too loud!).

I recently added a Dyna S ignition to replace a bad igniter and am in the process of relocating one of the mounting brackets for each of two Dyna Green coils because my originals overheat after about 5 - 10 minutes of running. Hypothetically the improvement in spark ought to result in a slight improvement in overall performance, although I don't really expect to feel a difference -- I chose the aftermarket parts because of the reported improvement in reliability over the stock Suzuki parts.

The latest project I'm going to undertake is to cut off the stock cans and adapt two Harley FLH cans (which I got free from the local Harley Dealer!) to quiet the bike down. I might wait till winter to start this project. I considered the possibility of completely removing the stock exhaust but after reading several posts about broken exhaust bolts I decided not to mess with mine right now. Ironically, the Harley cans will be the best looking part of my bike, which has a lot of surface rust. Once I have the bike running reliably I'll attack the aesthetics. I'm actually very happy to report that the original seat is in mint condition -- it sounds like most GS seats haven't faired as well over the years.

Future projects include lowering the rear end and putting better shocks on the bike. One thing I've always liked about this bike is that it looks like a bigger bike than it is. Good luck with yours!

Hi, thanks for the post...

Mine is 100% stock. it has the sissy-bar w/backrest, and case gards (i dont know if any came that way or not). but it looks very retro and i dig it. so i really dont want to do anything to it that will change the way it looks to much. it does have a little rust and a scrach/dent here and there, but this winter i will re-do everything to make it look loke it just rolled out of the dealership showroom.

I know what you mean about the "too loud" thing. my uncle has a harly bad-boy edition. it's phat but way to loud. when he starts it windows rattle in the next town over. i mean it definatly gets the testosterone pumping (I am man hear me roar) but come on...

i am by far more interested in performane then noise...

anyhow...
i am just about to buy the Dyna 2000 ignition, do you or anyone else know of a reason that i should go with the "S" or "3000" series or whatever??

thanks again
Van

your best bet is there is a yoshimura exhaust for sale on e bay, they are the cream of the crop, that sez it is for a 550, i went with the mac exhaust because i got a deal on it. you could try calling these guys and see if they have any exta exhausts milwaukee cycle supply salvage. 1800 359 6014, any 4 into 1 you find will be a good performance increase.
