^ Geez that's pretty incredible. Do you have a write up somewhere I could gawk at?

I've stumbled across this on the wiki, I wish there was more:

Sorry, no. I ran across the bike at a show in Pittsburgh. But being that it's a Suzuki GS, the folks over at the GS Resources probably know all about it.

there is more to the turbo wiki, there is a thread kicking around somewhere

This is why I love this group. Great ideas and great laughs!

I think I'll explore the sticker idea and rejetting. Maybe upgrade the sprockets.

Just looking for something to do over the winter.

Can anyone suggest a good place to get the rejetting done in the Toronto area. closer to the east end would be preferred.

Thanks

I don't know how handy you are but you could do that yourself. I live on the far east end of Toronto myself and just picked up a new set of jets at Snow City Cycle Marine (http://www.snowcity.com). I'm not sure how good the workshop is because so far I've only worked on the bike myself but I'm sure they can do it for you as well.

I'll definitely check out Snowcity. Thanks for the info. I'll do a little bit more research before I try it myself.  I always fear of f**kin the bike up when it comes to the mechanical components.  Let me know when you do yours and how it went.

Sprockets just gives you the Illusion of HP. But, that's what matters... the Illusion.

If you want something to do over winter... how about move to somewhere where you can Ride all through winter  :dunno_black: :thumb: :thumb:

I ride until there is snow on the ground or it drops below 0 but it would be nicer some where warmer.

Nepronic, if you do decide to re-jet, make sure it's after any intake/exhaust upgrades. May as well only do it once. Buddha can sell you a jet kit, and I highly recommend doing it yourself. It takes about 2-3 hours if you have never done it before and you will become familiar with your carbs. Plus, some shops charge an INSANE amount to do carb work.

Out of curiousity, why rejet after the upgrades?

Any changes to your intake and exhaust system will change the requirements for your jets. If you rejet for standard intake and exhaust you will probably needs to rejet again after you change your intake and exhaust. It will save you some work if you do it all at once.

It changes the requirements because you have changed the airflow in and exhaust flow out.

I worry a bit about that too but I don't let that stop me. I'll give you a shout when it's done. I hope to do it before I put the bike away for the winter so I can make sure it runs good before I clean it and stuff it in a corner of the garage for a couple of months.

Btw. the wikis and the board have good information on what parts to get and how to make the changes. It's also a good idea to have something like a Haynes manual handy.

Well I seriously not mean to be rude but before you do any mods involving carb work to your bike make sure you read about what you;re doing and why you're doing that.
It will help you understand the mechanics of the bike and will make working on the bike both easier and more fun as you will not have to do the same thing twice and spend more money than necessary.

And believe me I was the same way, I rejetted my bike few months after I got it and I could still barely ride it. Now after 6000 miles of everyday commute for the past 2.5 years I have learn that ability to ride well is much more important than having extra 2 or 3 HP.

With that being said, modding is part of fun so go ahead and mod as much as you want  but set your priorities. Learn to ride, learn the mechanics and mod as you go.

Or forget entirely what I just wrote as I am bored at lunch break and have nothing else to write :)

Just make sure to RIDE SAFE and HAVE FUN at all times

Mod the bike to make it more rideable... Mod if for fun. I wouldn't mod it for more horsepower unless you plan to race. With a little suspension work, it's all down to the rider. I used to regularly put the smack-down on 600s and liter-bikes in the fastest groups at local trackdays.

The jetting is worth doing on a stock bike, since it can improve throttle response, and the general health of the engine.

I didn't take in a rude way. You are actually right. I've been riding for a year and a half and have gotten to know the bike well. The one thing I'm actually looking at doing first is tightening up the suspension (Front). My bike is an 06 and it feels very bouncy. As for the HP I am just looking at what is possible and if it's even worth doing. Realistically, I don't see the need for anything above 600 cc bikes. How fast does one really need to go.

BTW, I put 10k on the bike just this season. Good times!!!

Right on!!!

From Gears 1-3 is there any way to make them runs a little longer with out losing torque? bigger Sprockets?

Bigger front, or smaller rear will make the bike run a little further in 1st gear through 3rd gear. It will make it a little more difficult to get the bike going from a stop. The GS seems to do okay with stock gearing, or lowering it slightly, since it doesn't really run too high in the revs in 6th gear.

I wouldn't recommend doing anything extreme, like a -1/+2 swap.

Stock suspension on the GS is pretty terrible - I cross referenced the parts, and found that it was sprung about right for a 40lb rider... Especially bad for those of us running Radial tires.

I seriously wouldn't do anything else before sorting out the suspension. I literally had a complete front end and shock upgrade on the bike before I even started the engine for the first time.

Suspension is definitely a must upgrade on a GS500. I went with Progressive Springs for comfort but now I wish I got something a bit stiffer.
I wish I could put 10K miles in a season! Between work and school there is not much time for me to ride just for pleasure and my commute is relatively short - less than 20 miles a day.
