Thanks Pete! We are having some very strange weather here lately. A couple days ago it was about 20° (Celsius) but right now it's a couple degrees below 0. The low for Tuesday night is -25°! But regardless of the temperature, the roads get covered with so much salt that it makes riding kind of sketchy. The moderator here GSJack lives relatively close to me, and I don't know how he rides so much!

Good eye Adidas, but it isn't made from any wood from an alley. The majority of the bench is made from scrap wood I had around (2x8's, particle boards, and 4x4 posts) but the top layer is made from scrap vinyl decking. The vinyl decking won't absorb oil like normal wood, and can't be "punctured" by a kickstand. A friend of mine in Canada has a normal workbench in his garage that is made from a bowling alley though.....his looks great!

Forgot to update this.......

Got my Avon tyre in the mail and actually mounted it myself. Normally I take tires to a shop to get mounted, but didn't have time when it came in. I was really surprised at how easily it went on! I didn't even need tire irons - just pushed it on by hand.



Also got the master cylinder & caliper filled with brake fluid and bled the air out of the system. Still working on a fender brace, so that's why the fender isn't mounted up.......

Hmmmmm......closer definitely. But still plenty to do. Here's a quick rundown:

Order rear tire and mount it.
Weld bracket to frame for master cylinder
Hook up brake hose and run fluid
Order 520 chain, finish lining up front and rear sprockets
Paint frame and swingarm where they were welded
Install headlight, signals, etc
Wire in GS500 hand signals
Install choke cable

I think that's pretty much it? I'm sure I'll find a couple more though......

Ah, forgot about the 520 conversion... still that's not so much to do... at least there's no "assemble engine" in the list :D

Wow. I need to update this more often.......  Tires and brakes mounted:

Rear brake setup:



That's a GS500 rotor, caliper, and master cylinder mounted to the Bandit 400 wheel. Had to mount the fluid reservoir behind the plastic sidecover and have a custom brake line made.

Chain side:



Not much interesting here. Did a 520 chain conversion (stock chain is 530) , and the 130/70-17 tire was rubbing on the chain guard so that got cut down a little bit. I do have to say however, the GS5's caliper and tire is a million times better than the original drum brake and 100/90-18" tire.

Very nice, looks like a good upgrade! I would like to upgrade my lighting on my CBR as well haha. Looking for some HIDs but I have some other more important things to buy lol.

I am into buying bikes that people have given up on and fixing them up!

RIP Patrick Lajko, I miss you man.

Big Rich

Thanks man! The vast majority of my riding is during the day but I wanted more light for the few times I do ride at night. Hopefully in a week or so I'll be adding an led fog light from the same company.

the bike looks great, any idea where to start jetting wise for a set of the 500 carbs on a 450 with pods and open headers?

Big Rich

Yep - start here:
http://wiki.gstwins.com/index.php?n=Upgrades.Rejetting

It depends what model carbs you have, and what intake you are running. The chart will get you in the ballpark. That being said, I have to tell you running open headers is one of the worst things you can do. The short length of the exhaust is robbing horsepower from the engine, and even if you extend the exhaust you'll only gain any power at a very short range of rpm's (which is why drag racers use them). Not to mention it's like putting a sign on your bike for police that says "asking for trouble".

eh, there not really headers, we built a set of pipes with out baffles. http://imgur.com/FuxFs i wish i had a better picture, but the pipes continue all the way back to the footpegs.

I had not sir, thank you. That video makes it look like a bike takes a day or two to build......

It does  :D

Good site though, they seem to have worked on a few GS project bikes. They look great!
