GS1000 streetfighter idea w/ picture

A couple of photos from today while waiting for it to drip-dry at the carwash:

like i said these are rough numbers, I'll let you know what the hp numbers are once i put one of these 1k motors together. hopefully by spring......

Id stick with the 2 valve. Its more period authentic and it seems its much more rare to see a built 2 valve GS.

Mine sounds a lot like this one: http://www.youtube.com/watch?v=XEAUAD78Imc

The 1100s and 1150s sound awesome too, just different.

Love this video of an 1100 in action. That blast of torque from 0:17 to 0:20 is insane. http://www.youtube.com/watch?v=-EI4E-K6xFI

Does the 2 valver sound a lot different?

To bore a block is $300!? That seems a little high; are you sure thats correct? Im not going to get a professional port/polish job; which will save some bucks. I think Ill just be very careful and smooth any rough casting marks, attempt to polish the exhaust side, and try to match my intake boots to the head as best I can. All this performed very slowly and carefully of course. Like you mentioned I want at least 100 RWHP too. I think it will be easy to get from: 1085 kit, 29mm smooth bores(cross your fingers) , K/Ns, good exhaust sys, dyna coils/ign, cams, and most importantly; cams/timing and carbs set up properly. The bike I want to model mine off of is in the july 2006 issue of motorcyclist. Im thinking of even doing number plates, but have the front plate perforated so the head light shines through when lighted. Also flush mount turn sigs. Other ideas are to cut twin oval vent holes in the cooley fairing to vent a hidden oil cooler on one opening and place that heat generating Rectifier/Reg. in the airstream behind the other. I dont know if this stuff is possible due to the size of the bikini fairing; but its fun to think about.

Hrm, wonder what kind of performance numbers you could get with that motor configuration? Part of me wants to build out the GS1000 motor since it'd be more authentic and the 2 valver sounds incredible, part wants to replace it with a GS1100 or GS1150 or even GSXR 1127 16 valve motor. Might be more cost effective and reliable?

500 piston kit
300 bore job
800/900 port polish
50/200 kz650 under shim buckets
400 cams
75 16v 750 oil pump gears
100 gasket kit
400/500 weld balance crank + 100 for lightening
200 billet clutch basket
200 earls oil cooler set
75 ape cam chain tenioner
90 good cam chain
120 gasket kit
120 clutch disks
200 for engine cleaning/blasting for gunkote black paint

so for just a quick calc, spliting the differances with a few things looks like about 3700 buck, You can look most of this stuff up and come up with solid numbers I am just trying to rember what i came up with last time i looked into want i wanted to do. Best thing to do is slowly collect parts.

opps forgot to add need some good carbs to let the motor breath 600/800 +150 for filters... yeah fun costs money

i am kind of in the same boat as you guys but would perfer to run vintage race parts instead, so if you ever have a lead let me know. I am about 50% of the way there now.

Are you also going to replace valve seals and guides? Im planning on the same bore kit as you in the next year and am curious what all should be replaced. Im trying to approximate expenses. In the next year Im going Wes Cooley replica all the way; But a little different: with Radials, Gsxr front end/brakes, GS11000 swingarm. I want to get as close to the bike featured in "motorcyclist magazine" (1980 spec machine) as I can. Im talking bikini fairing, paint, decals, velocity stacks, possibley race numbers...the whole shabang. When are you geetting your engine work done? Im very curious what your expenses will look like.

The motor work will be done when I can afford it.

I think the bodywork paint (tank, tail etc) and seat will get done before the motor work.

We want pretty much the same thing in the end - a Yoshi GS1000 replica with uprated running gear, brakes, and motor. Here's that magazine article you were talking about: http://www.slcelectronics.com/GS1000...Yoshi-Article/

i figured to built a serious gs1000 motor you are going to need about $3500 in the bank. keep in mind a good head job will cost you about 900 bucks.

What would that $3500 buy you?

They needed those wide bars for leverage. It takes muscle to push a GS1000 through tight turns. I'm told Cooley used to yank so hard on his bars that they bent.

What route are you going to take with the engine?

1085 kit, new valves, and replace the tranny for now since it slips out of second gear under the gun. I found a complete GS1000 tranny in good shape for short dollars ($60) so the whole thing will probably be swapped out. Maybe do a bit of porting and lap the valve seats too. If the budget allows, weld, balance, index, and lighten up the crank. I'd like some more performance but not at the expense of reliability or streetability. If it put out 100-110 HP with good torque I'd be happy. The motor's got 32k miles on it and could use a bit of freshening up. Paint it black like the Yoshi GS1000 bike.

man its weird to see a race bike with upright bars like that....it works for him i guess and thats all the matters but how often do you see em sittin up like that hehehe

That's a good point - clip-ons were around long before the 80s AMA Superbike racing. Wonder why the guys selected handlebars over clipons for racing? Was it an AMA rule or something? I'm seriously considering putting the clipons back on the GSXR forks because the riding position is better for sport riding.

I think blue/white Yoshimura wins in terms of paintjobs - it looks the business and honors this bike's racing past too. What do you think?
