'83 GPz1100 Streetfighter ... changes
- Thread starter Fossil
- Start date
Thanks Noel. Nope, no intention to run the pipe up under the seat. I like the old 80s Superbike style header and small muffler style. It's an old bike and I'ld like to keep that "feel" to it. The pipe needs a sandblast and repaint, maybe wrap again, so I'll have the stainless steel muffler blasted at the same time to knock the shine off, give it a satin finish.
If I could of economically upgraded the forks, swingarm, wheels and brakes without using modern components , I would have used shortened late model conventional forks and had 17" wire wheels built, but the cost would have been prohibitive. Used sport bike parts are fairly cheap and readily available.

Carb trouble? I thought the '83 GPZ 1100 had fuel injection

If I may make a suggestion...
You should cut some sheet metal or fab up some fiberglass covers (hack the OG sidecovers?) to better guide the eye from the end of the tank to the beginning of the seat. Not to go further down but just to keep it as a flowing line.
I made my own sidecover for my KZ out of sheet metal so that it would be slimmer than stock, its pretty easy.
edit: shitty paintshop chop of what im talking about.

Thanks but I really don't like that, looks very close to stock. Besides, the idea is to shed weight, not add parts for the sake of style. The only extra for the sake of style part on the bike is the little Buell fairing, but it's carbon fiber and does actually help a bit. The speedo and tach are combined in one electronic unit from Acewell, and the fender and seat are race weight fiberglass. Looking for more parts to strip off, drill out, replace with aluminum etc.

Is that the best you got? OK.. now my TURN...
Fossil said:That would work!

Oh.. and quit PMing me Fossil!!!.. I dont wanna trade my cb750f for your GPz... LOL...Well Ok.. you've convinced me!!!.. LOL!!!...
I think your bike rules so far man. I think you're at the stage where you're going to have to go with an aluminum subframe if you want to lose anymore weight. It really would be a piece of cake too, considering that you have a monoshock.
Other things I noticed:
Change those stock rearsets with some anorexic ones. Those things with stock footpegs and everything are HEAVY.
Are you still using the stock steel mounting plates for all of the electrics and the original steel battery box?
How big is your battery? The newer sealed batteries like the ones on the R1 are pretty lightweight and compact.
Kickstand? Steel or aluminum? Its not like you're kicking it with a kickstarter, an aluminum one will do just fine.
Does it still have the centerstand brackets?
You could probably lose at least 20lbs with this stuff.
Good luck, I know the weight reduction thing is like a disease. Nothing is ever light enough when you get invested into it.

Thanks for the comments, I appreciate it. Yep, the rearsets will be replaced this winter. Plans are to replace steel mounts and brackets with aluminum and a fiberglass battery/electrics box. All the extra brackets and uneccessary gussets on the subframe will come off eventually when the bike is stripped to nickel or chrome plate the frame. I'm thinking of modifying the stock subframe, but might consider an aluminum sportbike subframe. The centre stand brackets are gone to make room for the pipe. A friend made a Ti stand for his bike, so maybe I should talk to him. So far I have shaved off a fair bit of weight - for example the wheels are each 9lbs lighter than the originals. What can't be replaced will be drilled out if possible. It's taken 3 years to get to this point, so I'll just keep tinkering away at this pace until its time to strip it down for the frame refinish.
