Hi Guys,

I thought you might find this interesting. This is an 1143cc (3mm overbore with a 4mm Stroker Crank) street motor we just built with one of our new KWS CNC Pro Heads. We were VERY happy with the results. We used a relatively small cam combo for more midrange and torque and were able to move the peak torque back down the rev range almost 1000RPM!

The base line run (red line) that this is being compared to is a stock bike with a Powercommander, Ignition module, and a LeoVince Corsa Full System. Again.....this is a pure street motor (Blue Line).....Ride to Starbucks or ride it to the next state. :cheers

how much money would it cost to build a motor up like that?

bet you might wan't to hang on when you give a hard twist.

not bad for all motor but still no where close to turbo or supercharger power... how much was the entire cost of the build?

Jetspeed - You are absolutely correct that a turbo application will produce more power than an all motor application. But if you want the turbo to make any significant power gains and hold together for any period of time you have to build the motor for it, so you end up spending the same amount of money, plus the cost of the turbo. And after riding a bunch of turbo bikes....99% of the time, a built "all motor" bike is faster because you can actually use the power. This particular application runs, rides, idles, and acts just like the stock bike....just with a LOT more power. There is no waiting for the power, its always there and you never have to worry about the bike coming on boost mid corner and sending you to the moon. For absolute power, you can't beat a turbo....but for rideablity, nothing beats a built big motor!

:drool :drool

Very very nice done.

Chip i have to say thats a pretty accurate statement you made there, ive built tons of turbo setups and NA for cars, and the turbo guys always expect instant gratification longevity wise which just wont happen unless the motor is built for a turbo setup... having ridden both a 190+ rwhp all motor gsxr 1k and now my turbo 1k, i have to say its a toss up, both are fun but for the track im just as happy my old 600 or 750...

fantastic.
I rode an 01 gsxr1k with the 3mm over pistons but no stroke, and he claimed about 185whp... it felt totally rideable, and just as smooth as the stocker.

You use the stock ECU with a pc3 for engine management right? How aggressive do you guys get with the timing on your built big gsxr1ks, cause it looks like theres a lot left if someone wanted to turn that into a high rpm racer :) Also, do you balance/blueprint the rotating and reciprocating assemblies, or are all the aftermarket internals close enough from the manufacturers? I know the stock stuff isnt...

Correct, stock ECU with PCIIIUSB (2) , Ignition Module, and Qucikshifter. Yes...the motor is completely balanced and blueprinted.

Yes...there is a lot more power in this combination if someone wanted to sacrifice reliability/rideability.....this was built from the start to be purely a street motor. If somebody wanted to sport tour accorss Montana at 200mph plus, this bike could do it. :punk

Good point...If you don't rebuild the motor to handle the turbo you'll run into serious reliability issues..Sure you might make more power but what good is it if it's not working...And it'll never come close to the power delivery of an all motor build....And trubo noise is annoying...

Would a street bike benefit from the 2 PCIIIs? I am guessing that you would have one for the primaries and one for the secondaries?

so basically for $8200 people can have a bike with over 200HP.. very good deal:cheers

Chip, what could you guys get out of the K6 750's? Any plans of doing something with them?

yeah trade it for a 1000 and you will get about 50 instant hp..

lol, harsh but true.

that 200rwbhp monster is awesome! such linear power too!

Chip, what could you guys get out of the K6 750's? Any plans of doing something with them?

We get more than 148hp out of an 06 Supersport motor...and that is with almost 100% OEM parts.

I have a very, very intresting 750 SBK motor going together right now.....stay tuned! :cheers

Would a street bike benefit from the 2 PCIIIs? I am guessing that you would have one for the primaries and one for the secondaries?

Correct....big motor stuff needs more control of the secondarys. Using two PC's is the cheap/effective way to do this with out the added complication of a race ECU for a street bike.

nice!
(creaming pants)

Chip that is some good stuff and I noticed you said about the deal with a Turbo system. What about the supercharge setup? can you still have that same work done and not conflict with the addition of a supercharger?

I wonder how this supercharger setup compares as far as rideability. I'm sure the power would be more linear than a turbo kit and feel like a big bore motor. http://calisuperbikes.com/index_files/Page503.htm

They claim 225hp for $4200 plus labour.

What are your thoughts on this kit?

A Supercharger would have a more liner power charecteristic than a turbo....but not as good as an all motor set up.

Also...again...that $4200 only buys you the Supercharger kit. Stock rods and pistons will not hold up to 200 + hp for long. So you have to build the motor. Back to what I was saying earlier. A Turbo/SC is not a substitue for a built motor....you still have to get the motor built if you want to make any real power for any length of time, plus the cost of th turbo/SC.

With a turbo or SC you will ultimately make more power, but it will cost you way more.

P.S. - we have built motors for both applications.

Supercharged 1143...mmmmmmmmm :punk

Sweeeet!!!!

Chip,
Just curious ..... after being in this dragracing game for 20 years ..... you are the 1st person to recommend riding a stroker 1000 on the street. I have numerous friends with 1070cc 1000s ...... and every single one tells me the same thing: "My builder never recommends riding a stroker on the street". I'm talking about well-established builders: Lee, Carpenter, 4th Gen, etc.

How many streetable stroker 1000s have you built and how many street miles have your customers put on them?

Thanks,
Mike

Sorry for the delay....I was at the PRI show in Orlando...

This is a proven combination. We have been building 1143cc motors since 2001 and have bikes that were built back then still running around.

There is no absolute about storker motors......there are definately stroker combinations that I would not recommend for street use, but this not one of them...

Thanks. You guys must be doing something right down in SC :p

1st time I ever heard of a stroker to ride on the streets.

Happy Holidays & Best Wishes in 2007.

have to guys tried to put anything else on this setup(pc III,pipe)to see how much more horeses yall can get out of this motor eversince the thread was posted?????

Thanks:cheers

Martin:cheers

This motor is done....like I said, we have been doing this combo since 2001. I can make more HP out it, but it would sacrifice reliablity and since this is a street motor that would not be a good thing.

P.S. - I rode this thing the other day and it is the stupidest bike I have ever riden. Power wheelies in any gear at any speed......retarded.

Bikes done....:D

Anybody see the latest issue of Motorcyclist? :D

I saw it !! cool article huh?

I don't see a pic anymore?

no what was in it?

It was a dyno chart...I guess it got lost in the last Gixxer.com update.

Here ya go:

I just creamed my pants FYI hahah

Chip: I live in Toronto Canada. How would I be able to get you guys to build me one of those motors? It would be an offseason thing.

Ship the motor or bike to us....wait 5 weeks or so. Give me a call if your interested.

hey chip does anyone make a forged stroker crank. id rather put that in than have to facotry one hard welded and grinded.

No billet cranks for the 1000...no need for it.

so the factory crank reground is ok for high boost and high nos applications

Werd. You are definitely right about n/a being more streetable. Turbos are definitely all drag power. My turbo kz900 with RCC kit (398hp) scared the piss out of me when I drove it on the street. For everyday power, I would go with n/a.

+1 to that. but man those bo's are nice on the strip!! lol hey what you think about an 1174 motor? 4mm stroke with a 77mm bore? ever seen that done?

Yep....it would be drag only and if you go that far you might as well go with a 78mm bore.

im scared of 78 lol. how much material is between the holes @ 78?

Yep....it would be drag only and if you go that far you might as well go with a 78mm bore.

Hello Chip! Now that I have my 1070cc ready, of course I want more :biggrin

I think that your 1143 crank would suit my needs.. I have Yoshi ST-R Type R cams, are those good with 1143 kit? What kind of power can I expect with those?

I'm also planning to go +1mm in exhaust valves, as the exhaust ports are limiting the flow of the head. The pro guy who made the head said that now the head flows the max possible with standard valves.

Do you think that it's good idea to go with your +4mm crank, Yoshi STR and +1mm exhaust valves?

Thanks again Chip!

Yep. The yosh cams would work great with the 4mm crank and the 1mm over valves. Big power. :punk

so would the 1143 be able to hold up with a turbo or juice, or both?

Depends on the build...but yes. We build them for nitrous all the time.

You guys are swesome! My K7 G1K is coming to you soon for work!

*ACE*

I have an 05 600 and just picked up a set of yosh R cams off a friend who never installed them. Can I run these in a stock head with springs or should I plan on saving for some head work?

As far as I know there are no R cams for a 05 600. I think they might have made an "S" cam, but I am not sure.

Yes, you can use them with a stock head, but you would need to change valve springs. Most of the kits came with the springs. Make sure of what you have first and foremost.

+1 to that. They could be R cams for a 1000 ! who knows

Do you have a part # on them ??

Do you use the same cams from the stage 2 build for the 1143 kit? Do you discount anything for returning customers (hint, hint, nudge, nudge)?

Yes.....and Yes. :biggrin

chip so what kinda discount am i getting if i bring her lets say july/august for the refreshing of the motor and then drop a 1143 in there? i mean i know i need stroker pistons and a stroker crank. my rods and cams should be good. so hint hint if i go this way what would it run me in total with the labor (which i assume is what is discounted for a good customer :))

pm me something to work with so that i can show the wifey and hopefully come up there drop her off and leave with a bike that makes 10hp more and 100 plus ft/lbs torque

Chip glad I found this thread. I have a buddy with a big bore Busa with a stroker that he said was built up in SC. I know a built 750 with NOS that I had year before last wasn't even a warm up for it. LOL! I have a turbo 1000 this year and will be running both at Atlanta Dragway. He is a little afraid of his bike and I'm not so to be fair to the bikes I am running both.:biggrin Glad to know you guys are out there. I will check with him and see who did his work. Oh yeah my turbo bike dyno'ed at 228rwhp. :cheers Both have air shifters and extended and strapped. We will see.....

FWIW, when I was at the KWS shop there were more (customer) dragbikes there than anything else. I think he'd be in good hands there. Obviously I'm happy with the work done so far.

I just finished my 1143 and it runs like Jenna Jameson phucks.

You phucked jenna jamison? Damn, you're a lucky man, an 1143 and that too, hahahaha:)
