My gs500 project. Hopefully a 600 killer but still completely streetable

[tunedbybugaj]

I am new to this forum so I figured that I'd put up some pictures and information about what I've done with my gs and see what you all think. It is a 2006 Gs500F and I purchased it over two years ago before I got my license. I was only 15 then so it had decent power but you can always have more  . All of the mods have been done by me and my dad. Mostly me. Here is the list so far: SV650 rear shock, handmade fender eliminator, led turnsignals and tail light, mirror blockoffs(sometimes), Jardine full exhaust, K&N lunchbox, custom jetting, Ported head(by me and my dad), head is decked .025, custom ground cams by webcams (.340 lift), valve job, 5 degree ignition advance, Puig windsheild, wheel lips stripped of paint, and more to come! The bike runs AMAZING! The cams are still just breaking in so it will be on the dyno next week. We use a dynojet dyno so the numbers are lower than other dynos. We are hoping for 50hp and 36ftlbs of torque. It revs so fast that the tach cant keep up past 7k and when using mirrors you have to make sure they are tight otherwise when the power comes in they fold up  . I hope you guys enjoy and any feedback is appreciated. Oh and idk how to post pictures lol

pics or it didnt happen.

thanks Phil!

With a title like that, really interested!  Great pics by the way.  I'd love to see it against an F2 or F3.  What does your pops do?  I'm thinking he's got some good xp under his belt?

[tunedbybugaj]

Thanks! and yea me too. I think I have alot of 600s in the 1/8 but im not too sure about the 1/4. Alot of people with 600s around where I am are inexperienced riders with either stock or slower than stock bikes but theyre extremely cocky. And if it doesnt beat 600s the way it is now then I have another trick up my sleeve that will help me win for sure . and my dad has been working on bikes for over 30 years now. he started the whole tuned by bugaj thing and hes built countless high performance engines. if you wanna see more highly technical and really cool stuff he did then just google "tuned by bugaj" and theres a guy on the R1 forums named Dee who has a really good write up on everything done to his bike. If you love bikes then you will definately want to read that article.

Nice looking bike.  But no way it beats up on 600s.  Unless they are really old, really crappy or have poor riders.   

Still, props for thinking outside the box!   

[tunedbybugaj]

Hopefully your wrong shonole but I completely understand where your coming from. But if this setup doesnt work then I do have something for it that will make it faster than most 600s. I definately will not mess with daytona 675s though. theyre in a completely different league. Hopefully next week ill have it at the track to get an idea where I am

[shonole]

Hey, me too!  I'd love to see a GS put down some serious power.  I'd be next in line to mod it!   

[cbrfxr67]

"then I do have something for it that will make it faster than most 600s."

Spill it!  Got me really interested now!  C'mon tuned, itching to hear what you have in mind!

Forced Induction? Nitrous?

Or something more Spy Hunter, like rockets and caltrops?

A wee turbo on a GS would be a nifty set up. I've heard of it being done, but never seen it. Does anyone know how much can you bore out the cylinders on a GS?

And you're my favourite poster for today for making reference to my favourite computer game ever.

He gets bonus points just for saying "caltrops".

caltrops. 

Not as good as "magma", though.

[tunedbybugaj]

Alright heres my plan. It is forced induction but not a standard turbo or nitrous. My dad built a gs with nitrous probably around 10 years ago and he could run up to a 75 shot reliably on the street and he beat most 750s. I went to the Indianapolis dealer expo this year and saw a 200+ horse turbo gs500. Ill have to look through my stuff to get you more info on that but it was used for Bonneville. But anyways the plan for my gs is an electric turbo. Very cheap and fairly simple to put on. It boosts probably only a little over one pound but I am gonna try to add and extra battery and take the turbo up to 24V. 1-2 pounds of boost may not seem like alot but 1 pound of boost is what the most efficient ram air system achieves. but ill have my boost whenever I hit 7/8 throttle. I think its a pretty cool idea, all i have to figure out is the wiring for 24V

[cbrfxr67]

  sounds interesting but what did pop's say 'bout that,.....

[tunedbybugaj]

He loves the idea and me and him have been trying to figure out a bike to do it on for a while actually. Im gonna wait a little while before i try it though because we have to make sure the motor is good the way it is now

Look into an LM2586. It's an IC voltage multiplier.

[tunedbybugaj]

Very cool comradeiggy. Were thinking about just hooking up both batteries in a series and then the blower going to the secondary battery and have switches to change from the blower coming in and running 24v off the smaller battery to just being a parallel and charging the smaller battery after I make a run. We just have to make sure the rest of the bike doesnt see 24v or else were in trouble lol

[GI_JO_NATHAN]

Yeah there's video on here somewhere of a turbo F/I GS from a few years ago.

OP, you had me up until "electric turbo." Then you fell on your face.

Also, Ignition advance doesn't do anything for late model GS's, I think 02 up. They automatically adjust, so after you advance it, it will switch back to normal. And your mirrors were definitely loose, They don't fold in like that on pretty much any bike.

Oh, and by the way, I'm one of the really nice guys around here. So your post has for sure hit a sore spot.
