900/1000 dogs compared to 650/750?

so, these guys are telling you not to build the bike you have, instead keep buying stuff from them???

one thing about these country mechanic types, they'll feed u a line of BS a mile long, THEY LAY IT ON THICK AND HEAVY and laugh at ur ass when u walk away behind ur back, specially if u aint from their "neck of the woods" and if ur giving them money WHOAA DADDY :woohoo:

faster as in what? drag race, road race, stop light to stoplight, twisities, alpine passes?

I am pretty much betting on the 750. building now a gpz750/810 for vintage road racing in the open class and i'll be up against KZ1000's and GS1000's. We do have one horspeower track where i expect their power to make a difference but on the other tracks we run on, I hope that a 100hp/360 lbs lightweight will give a good fight to those 120hp/400 lbs behemots

I'll know pertty soon, first race is march 7.

Now now, shim under bucket is better performance wise buddy.

No reason to knock the 650/750 platform, its a solid design.

im not knocking it,im just saying every design has its issues.
those boys down south seem to have missed that point. :woohoo:
theres lots of 900/1000 motors out there that were hot rodded way back when that continue to run years later with just basic maintenance which goes against what hes being told,i know they continue to run because i have a freaking barn full of them! :laugh:

I mean theres no doubt that its heavier and probably doesn't handle as well, but calling the 900/1000 a dog is a bit of a stretch.

they have a road course across the river next to the 1/8 mile track.
its usually packed full of kids going sideways in subarus or sportbike riders seeing how far they can hang their bodys off the bike get a helmet full of grass and still keep bike moving! :ohmy: :huh: :dry: :blink: :blush: :S ,i have no desire to compete with those clowns! :woohoo:

I still want to know where this place is.20 minutes from my house and I still wanna roll up there and see whats what.bj

My hopped up KZ650 would take my friends KZ1000 with a Yosh header and 28's by 1/2 second every time down the 1/4 mile. That was when it was just 716cc's with head work Yosh cams smoothboars and a Yosh header now my bike is 810cc's. I remember out at the road races a KZ650 was in second place overall after 4 hours in a 6 hour race. Don't sell the little guys short.

There are two ways to make HP. rpm and torque. the 650/750 are rpm motors with a red line in the 10k range and the 1000 are torque motors with red line in the 8500 range.
Per cc the 750 makes more hp and the 1000 more torque. The 750 will have its hp sooner than the 1000 due to it being able to get to higher rpms faster. and yes the 750 is lighter and better at handling then the 1000 so as is the numbers say the 750 should win. but it will all depend on the race being run and the rider in it. Take the two bikes and equal things up. put the 1000 motor in a lighter stiffer frame use its phsycal size to streghten the the frame. then go into the motor and make it breath better so it wrapps up faster with a slightly higher red line and rpm range. Now you have a motor that is more efficient and will build way better power/torque to cc/ weight ratios. Now you can . use gearing to a better advantage. So what will you have? a race that will come down to the rider. Whether in a drag/top speed or road race the 750 rider will have to work harder to do the same thing that the 1000 bike is doing on its own. When my dad was building the kaw tripples he had a customer come in with a 500. The customer wanted the engine blue printed and all ports equaled /timed and carbs ballanced. The 500 customer then went to the local drag strip and blew away the local top 750. The 750 owner also a customer of my dads came in and told my dad " I dont know what you did to so n so's 500 but you are going do it to my 750." The end result was an est. 120 hp. 350/400 lb. 750 that nothing arround could touch. My point is every thing being closer to equal other then the motor displacement bigger can and most often will be better. Look at the new bikes, Every one is putting a 1000 in a bike very close to a 600/700 physical size for a reason. They are putting more power in the same basic package. My two cents are spend less money on an already awsome motor and up grade the package arround it. Lots of power in something that cant put it where it needs to go will get you nowhere, but a good amount of power applied more efficiently will and it is way more fun in the process. Sorry bout the esay but this is the basis for a possible future project and if i can fund it i will show lots of pics and bench racing.

I went to an old bike dealership here in Tennessee and talked to two old bike techs that are semi retired. I went in to show them my alternator(650c1) and ask them how to wire it. We got to talking about my KZ1000B3 I rode in on. They said the 900/1000s were dogs compared to the 650/750s. I will agree my 650 is as fast as my 1000 but the 1000 has a full fairing and bags and trunk. TJ the younger one(about 45-50) said his 750 was faster than the drag bike the other tech had built and the second man agreed. I was going to build my 650 as a cafe racer but might drop the idea of mildly tuning it. They said it was cheaper to build a screaming 810 than to mess with welding the crank and such in a 900/1000. Any one have info on dollars per horse power?

And the wind blew and the shit flew and I could't see for a day or two :woohoo:

I've ridden all of them. All nice bikes. But those woodchucks were laying it on pretty thick .....

Where I ride it"s twisties, and switch backs, big hp motors don"t give you much advantage, I've rode my 750 katana with zzr and r1"s and been right there leading the pack, but when we get to a nice straight piece of road I can tell they got the advantage, I"ve road 650 kz's 900 kz's and the 1000 all good bikes, but when that nice straight stretch comes around I would rather be on a 900 or a 1000.

Sorry this is so long!

OK I had condensed the first post down on allot to get a dollars per performance increase figure. TJ works at Griffithe's and yes I got a lot of stuff from them, two 650s and a 750 and a shit load of parts(some other guy got the 550 parts. They have a dirt floor garage of old parts bikes or did. Plus the name of a guy giving away a 1000J(88hp?)(stock) for free so I picked it up(he said it was a DOG compared to his 750(stock)(75-92hp?) so he gave me the non running bike to get it out of the way. cant remember his name but lives in or around Knoxville). TJ did not own the bike he worked on it with a buddy. The drag bike is owned by a guy who works or worked for Jamups, and before some one really stupid tells me they are no longer in business they just rented out the upper part. The side that sales the Korean bikes is still jamup's and so is the garage space.

What really got the whole 1000 is a dog thing started here(around Chattanooga) was a GS750 then a KZ750 out ran a KZ1000J at Brainerd Optimist Dragway's 1/8 mile track. At one point the posted time tickets were in the forum on there web site(middle of 2008) but I can't find them now. I have no info on the bikes they ran down the 1/8 except the one thing any one remembers is the 750's were faster on street tires. I don't know if they ran slicks or not(later after the street tire passes). ALSO I am getting a GPZ1100 that is not running and never laid down for some work on a guys house(I am a plumber)he is a plumber/ pipe-fitter also but retired and in to Harley's Sportsters now and does not want to go under his house. I talked to several bike shops here about my 6 wire alt on my 650c1 but no one seems to want to mess with these old bikes.

At one point the mechice at Scenic City Scooters said he knew the guy the has the old BMW store on Dayton Blvd and that he comes in to talk to them some times. The BMW place is CLOSED to all but his friends as he is retired and does not want to be bothered. The rumor is he had a BMW that was a screamer back in the late 70's early 80's. I wont get in to the Harley guy that spent 7 grand on a S&S engine to brag about beating(by a tire) a friend of mine's kz1000 with just a header and pods. If you come to Chattanooga some times you will see this S&S Harley sitting out side of Rumors. It would be nice to see a almost stock KZ smoke him.
