It's obviously a tough task too please all. I come right out and say I want a vintage tire, yet I get odd responses stating the obvious. I have better things to do than log on to a website and tell people what everybody already knows" he only cares about looks", this isn't a true cafe racer" if your going to make comments similar to that please use them under a topic where that is even remotely the subject. Seriously???? Thanks to all those that gave objective seriose responses. This is a show bike ... Not a cafe racer... Do you understand????? Is that complicated?????

Than just ignore the comments... It's a public open forum. People will say what they please. Build whatever you're building and ignore them. No reason to get upset man.
Most folks here don't really get the idea of a "show bike". Myself included. That said, it's yours. Do what ya want.

Driving a 70,80s cafe in 2012 is for show. if it was pure performance in the twistys we wanted we would all own modern sport bikes. Seems fairly simple to me. Half of the sites appealing to cafe guys are very show and image oriented. Just saying... My goal on this build is to have a unique design that is to my liking and when I'm done maybe others. In addition retaining enough common sense performance. I am new to this ill admit I more a fan of Dues,wreanchmonkees, and even some influence from builder like Shinya Kimura chabottengineering.com . While I believe every one this site can put clip-ons on there bike, make a home made cafe seat, put some playing card graphics on there bike, grind of some tabs, rattle can some parts and call it good. Is that called substance over style? Or just less of a build? Im going for a little bit more of a involved build than that. My original post was asking how to retain performance? I did receive a lot of insightful answers and pm about this and it was a great help. I will choose the tire soon and update.
Thanks for the help

Yeah, you really haven't spent enough time here on DTT. That's cool, I'm sure you'll get what most here about soon enough. A little hint? It's not "playing card graphics". Many of these bikes have been built with nothing but the addition of performance in mind. Do the builders care about aesthetics as well? Of course. Doesn't mean performance isn't more important.
And the reason we're not all out on modern sportbikes is pretty simple. Buying speed isn't really what most here about. We like making our "homemade cafe seats". We enjoy swapping out carbs to get that extra 2hp. We feel good knowing that what was once a cheap UJM is now a much better handling and performing machine. And most importantly that WE made it that way.
Any asshole with a credit card can buy a cbr600 and out run 99% of the bikes here. At the end of the day, they still have a lump of plastic that looks like 20, 000 other lumps of plastic. All good if that's ok with you, but it isn't my thing really. It would be nice to have a modern daily beater I suppose, but I wouldn't trade my old bikes for one. Ever.
You say your new to this, which is an awesome thing to be. You have the chance to really create your own style and your own path in the custom bike world (if that's your plan). It's also why the three bike builders you named are the first three ads you see on almost every custom bike website. Do more digging man. There's some way cool shit out there if ya look for it. Way cool shit that actually works (admittedly, Shinyas stuff is baller).
All I'm trying to say is that you're coming across with some real "know it all" attitude whether you mean to or not. Maybe chill out a bit and actually learn about the site and people you're dismissing first. Your "involved" build seems to be a stock motor, and a bunch of store bought parts to me. Maybe I'm wrong. Since all you've done here is ask for free advice and drop some negativity instead of sharing your build, I'll assume I'm right. Bummer, maybe if you can look past the self imposed facade of b.s. you see in this and other forums you'd see some really involved builds. May even learn something. Hell, you might even be inspired to put the AMEX down and make something of your own.

I would admit Dues is a little to played out and becoming very imitated by a lot of people. I do like the look of the wreanchmonkees bikes,but do realize there performance is limited on many of there builds. Theres nothing you can say wrong about shinyas work its just pure genius. I have been doing a lot of digging online believe me. Too much for sure. I do like looking at Pipeburners blog. They seem to display a good mix of pro builds, garage builds and every thing in between. Im just a garage builder. This is a hobby and nothing more for me. This bike will take a year at least. Nothing will be over looked or done half way. This site seems like a wealth of info. Im just not a fan of people wanting to stifle original thinking on a custom build or twist words. MY ORIGINAL POST WAS ABOUT RETAINING PERFORMANCE. I would not have spent the time to put a 2010 suspension on this bike if performance was not in my mind. In my mind one of the weakest points on a cb750 is there suspension. So its gone. Rear will get progressives. Frame will be braced in weak points for less flex. I was going to be posting about that at later date. Right now I simply wanted the best vintage looking tires I could buy.
"I bunch of store bought stuff". I'm buying what needs to be bought and fabricating what needs to be fabricated. Is there a item that you think I should have fabricated intead of purchased? Swingarm was fabricated, wheel spacers, custom fork conversion, lacing cb hub to 19 2.5 in rear. I'm only just started what should I have made myself in this process that I didn't? Seat and tank were sourced out to keep the quality high. That's it. It's not overly simple to put usd forks on a cb750 and keep a spoke wheel.

"Seems... to be store bought". Relax.
Start a build thread. Be part of this community. Than get upset if people question your hard work. One detail lacking photo won't do it. You seem to have a good idea of what you want and how to get it. Let people know that and shits gravy.

Mr Robbins,
I'm trying to be helpful here. The reaction you are getting to your questions is partly because the question appears to be an oxymoron and partly because maybe we are not clear on what you are asking.
You updated the suspension to make it handle and yet you want to fit "Vintage" same sized tires at both ends, that will probably make it handle worse than stock. Typically motorcycles have smaller front tires for a reason. That's what people are trying to tell you.
You may also have read that DOHC Hondas do not respond well to bellmouths and no amount of jetting gets them to run right at part throttle.
As to what you fabricate and what you buy, that doesn't add any points to the score of life. If you enjoy fabricating stuff that's great. Otherwise it's just not important. I built show winninging bikes with little or no fabrication of my own. Sure I had to change a lot of things but I had to get others to machine and weld things for me. Not everyone is blessed with those skills. What matters in life is how we treat people. The rest is fluff.
You asked for opinions and now you have another one.

I didn't get that at all. He came across with the attitude of he knows what he wants to do with his bike so answer the question if you can or shut up. Tech threads really should have better signal-to-noise ratio. If people want to get on their soapbox and pontificate about bikes, there's a million other places on this board to do it. The value of tech threads goes down the shitter if every thread is a philosophical debate that turns into a pissing match. The rule should not be "it's an open forum so I can barf all over tech threads," the rule should be if you don't have anything of value to add, be quiet. In the chat forums? Feel free to barf. Tech forum? Use discretion. It really adds value to the information if tech threads are concise and BS-free. I know the forum means a lot to you so hopefully my words mean something.
The value of the tech threads also goes down the shitter if every question isn't at least examined for value. I'm not one of those guys that thinks that there is no such thing as a stupid question and so if someone posts up a thread in the Engine section asking which rocket motor they should strap to the back of their bike, I'm not going to tell them. I'm going to tell them it's a stupid idea. If someone asks which vintage tires they should pick for performance reasons, I'm not going to tell them. I'm going to tell them.... well, you get the point.
The value of the posts on this forum (and in the tech sections, especially) are not just for the person asking the question. Hundreds, and sometimes thousands, of people read a particular topic and this is how knowledge is spread and disseminated. If those of us with knowledge don't weigh in on a thread (and sometimes with a contrary opinion) then we're doing the community as a whole a great disservice, but allowing mediocre (and often dangerous) ideas to continue to propagate.
Maybe I seem like a dick for posting what I have? I'm honestly beyond caring. I've spent enough time working with people (both on and off the Internet) to know that we all value different things. I would like to believe that most of us are here because we can exact joy in making our old machines better than they once were. And by better, I mean better in operations and functionality, and not just better looking to follow the latest craze. I feel I give everyone an honest shake, but sometimes I am known to cut directly to the point. This was definitely one of those latter times and I don't apologize for it. Call his bike whatever you want, but on appearances, it definitely makes a nod toward the performance aspects of motorcycling. The OP is making a mistake by opting for a vintage tire selection and I tried to point this out. This isn't Pipeburn. This isn't Bike EXIF. This is DTT and I am a proud member of this community that continues to place an emphasis on substance over style.

Awful lot of people don't like K81 (TT100) on street as it is a trigonal tyre.
Bike can get real twitchy with them
I loved them though, you don't really need brakes, they have a relatively small contact when upright and a much bigger footprint when leaned over, just toss bike into corners and the extra rubber slows you down slightly (or give it more gas ;D )
Better semi vintage look would be K70 front and rear, particularly if you have wider rims

Honda CB750 DOHC motors are pretty reliable as long as both cam chains are adjusted properly and oil is changed regular.
Couple of generator and ignition issues but not too bad.
They have just about impossible to tune CV carbs, the stock airbox/filter is the only thing that works
Switching to Mikuni is really the only viable alternative if you want to run K&N filters, preferably smoothbores or Kei-Hin CR carbs (using CV your back to the same mid range issues)

Maybe we missed your point, but you have missed a point too. Many of the 60's, 70's, 80's riders already own modern bikes.
You are right in one aspect, if you are looking to go as fast as you can, then a modern bike is the way.
But I like good handling bikes. I don't need 200 HP to ride well, I like riding a better, personal best, technical ride.
I have 2 friends I ride with the have a BMW 1200GS and Ducati ST3s. Either one of those bikes handles and is much more powerful than my NH750. But they cannot keep up with me on the highway or back roads, as they don't have any technical riding skills, unfortunately. I suppose my present CB360t rebuild would allow me to still ride away from them.
I like taking my old, slow bikes and making them better handling old slow bikes.
So when you asked about vintage tires, and then put a sophisticated front end on the bike, I, as many, assumed you wanted something better handling.
But never the less, you are free to read and accept or deny anything posted. It's free advice and worth every penny.
I am not into the cafe look, I like the more "slightly modified" stock version. But I am picking up good information from the various builds, lot's of questions, and panoply of answers. I pick and chose what I like, and you can do the same.
So you can read this, then accept it, or ignore it...Either way, my life won't change.
So post, ask questions, don't worry, be happy.....Nothing anyone types here can hurt you .
