Topic: GV1390's Trattoria "Racer" V2!

GV I take it your using your cr26 carbs for this build? Don't you think you might be a little under gunned now with the engine modifications? Stock 650 carbs were 26mm with an accel pump. Glad to see your making intelligent upgrades though.

The CR-26 carbs are very well suited to hot Street Bikes. They are easily
Jetted and tuned for very high HP platforms and I'd wager them to be a better carb than a 750 stocker. Any single component in the abstract can be questioned. But taken as a whole "system" of balanced performance, the CRs make very good sense. If they didn't, you wouldn't see them so frequently used in road race settings.

Just my opinion.

I'm also doing CR26's as recommended from MRieck. Anything larger won't be that streetable. It's more than the bore size for carbs. It's the shape of the inlet and such.

Let me clarify: Mike didn't recommend that I get the 26's for my bike, per se. He did recommend the 26's over any larger CR specials, though. For what i want my bike to do, obviously. Won't be a track bike.

Another option for you Dave and GV would be gpz600 ninja carbs. Exact same spacing as a 650 head. Just need the ninja carb boots for 79/80 cb650 heads. Very streetable, no bog or hesitation and lay down some serious power.

I got the same advice, too.

Unless, I find a better option, I will likely go with CR26s, too.  My main objective with this bike is to make good grunt on the street.  Top speed on a track straight is less of a priority for me on this.

Look into the ninja carbs Don. If I had a bunch of engine work done to my 650 it's what I'd use.

I don't know anything about those carbs but I'd say that would be an option if you're looking to save money. There are other carbs that fit these heads too (earlier heads because the 81 and 82 are different) such as 750 carbs.

Could be an option though, but not for me...I bought mine already! Also, I like the ease of swapping jets and needles without having to sync or remove the carbs from the bike. Another nice feature the CRs have.

How could you say it's a better option, though? Unless your opinion is price based? Have any experience with the Ninja carbs and CR26's on a built 650?

Purely from a price stand point and having the accel pump from the ninja carbs. GV has said numerous times how beautiful and trouble free his cr26 carbs ran on his bone stock cb550 motor, that I would be very hesitant to run the same carbs on a 674, Mike Reick ported, very aggressively cam'ed engine.

You still miss the point, Cam. That engine had a 600 kit in it, a 650 cam and aftermarket ignition and exhaust, right? What's none stock?
Even if it were, the CR offers the range of tuning to meet stock (probably overkill) to higher HP applications. How much HP do you think these motors are going to make? If you actually had the real world experience with them, you might be in a better position to warn someone off them. Yet, many folks run them in track applications quite happily. I'd say that is equivalent performance (perhaps better than these Street motors will get). Nothing particularly great or high performance about accelerator pump carbs. Different than the CR but who gives a blat.

I'm curious about your objective here? If the carbs are that
Much of a delta, install them on yours, dyno the motor, then publish the graph so these guys (Don, Dave and others) can see what a difference they'll make. Else it's anecdotal and subjective.

Now go build that new 550 dream Brownie you taunted us wth! I'm anxious to enjoy the end result.

Well, there is that EX500 Kawa motor that a few crazy Cali guys who do builds shoehorned into a CB550 frame and made a very very fun track bike with...lots of development & mods to get it all dialed in the way they wanted it  but it was ear to ear smiles and was really something to see.  Talk about a bike that would be a fun canyon carver with some throwbacks to Vintage. That could be.  I had a visually beat EX500 I picked up for $50 when I bought the cb550k. Sold for $100 with new manual and a few parts I had bought for it. It had been a runner when parked. Fuel tank had grit in the tank lock and I never tried to do anything with it. It could have been an interesting clone of that track bike.  Wonder if you could manage to title it...insuring it would be interesting though and you would have to shave off the Kawa logos to make it a little more stealthy.

Bump....

Will be doing a full part-out on this build for anyone interested. I will be creating a full part out FS thread within the next couple days with pictures and prices on everything.

Just a very quick rundown on some of the parts:

-674cc near complete engine (JMR head brand new in packaging, OEM Honda gaskets/seals/etc, DynoMan 674 piston kit, FBG cut back gears, every engine case/piece vapor blasted and painted by Nils, etc)

-Hindle CB650 complete exhaust brand new in box
-Calfab CB550 swingarm
-Brand new C5 Ignition Kit
-One off custom fabricated fuel tank by Christian Newman
-Cognito Moto wide rear wheel complete kit for a CB750 (can use the hoop for a 550, just not the spokes and offset sprockets)
-2008 GSXR complete front end with darker bronze outers with black inner tubes (only offered in one year)
-Woodcraft clip ons (brand new)
-Brand new aluminum sprockets
-MotoGadget wiring kit (brand new)
-Pirelli Diablo Rosso III tires (brand new)
-Spare with good compression complete CB550 motor


I'd really like to sell the motor setup complete, the wheel setup complete as well as the front end pieces. I will give a better deal the more you buy. PM me with any questions you may have.

Thank you!

Sorry to hear.

[SOHC4 Cafe Racer Fan]

  That's a shame.

Nick and Cam will have to "represent" the Upstate NY region with their 674 builds.

[GV1390]

Bump.

Updated the above list with what's left. Will be making a thread tonight as I've been very busy these last few days.

Thank you!

Hello
Is the motogadget wiring kit similar to the one you get from revival cycles?

I dare ask, why are you getting rid of the bike?
