Topic: GV1390's Trattoria "Racer" V2!

[SOHC4 Cafe Racer Fan]

I passed on the sureshift gear position indicator.  Useful, but damn that sucker is a wee bit awkwardly LARGE.  Too bad they couldn't build the feature into the Chronoclassic.

What's the story on the ap master cylinder? Why was the hole drilled/ tapped further back in your thread? I might be interested.

[GV1390]

Kind of surprised you are getting rid of that headlight. It was one of the things that gave this bike a distinct look.

I know, I know....was on the fence with it but then again, I have another one anyway just in case I change my mind. I may not sell it, who knows - regardless, not a big ticket item anyway.

I'd keep that MC to drive your new rear disc! It's a very cool part

I may! I have two of them. The master is 21.8mm so I need to make sure it'll work considering the rotor diameter, wheel diameter and weight of the bike as you already know.

I thought it was too large as well....worst case scenario I sell it if I don't like it or toss it on another bike.

The hole was tapped for the feed line as there was no thread from the factory. It was threaded so I didn't have to run AP's special reservoir fitting.

Are you race-cutting the trans, too, or swapping to GSXR rods? 

What's the ETA on your JMR head?

Nick and I both dropped our gear sets off together so yes, those will be cut as well. Not sure on rods yet, going to see how healthy my factory ones are. If they need something beefier ,they will get something beefier.

Last I spoke to Mike it was in queue so waiting on the master himself to get to it - no rush.

They definitely won't need something beefier for the power we're making, but couldn't hurt, right?

[GV1390]

Yikes! 21.8mm! That wold stop my Super Duty  Guess you'll need a smaller rear MC to replace it. 

Plus your S550 combined! AP Racing does make this stuff for NASCAR so, doesn't surprise me.

Better put all the recent $ candy in the safe as flatlander has been making targeted strikes if you believe his photos and claims of absconding with an exhaust from Scott in SC.
There goes 1/2 a month's discretionary fund, eh GV?
Wish I had that kind of discretionary purchase fund for 3 months...that would be nice...

I mean, how many options are there really besides Carrillo and a GSXR setup? To be honest, I rather put together something with proven results that's been done before...rather not be a test mule in a sense. The GSXR rods are slightly heavier...believe it was roughly 40 grams heavier per rod. Not sure how I feel about the extra weight spinning at higher RPM's. Granted you can have some rotating mass reduced elsewhere but still.

Haha. Those exhausts surely are nice but damn, that kinda dough is surely a lot! Can't say I'd buy a set for my other CB until this one is done....I also just put a Hindle on it in which I don't think I've even ridden it since. Thankfully selling some parts from V1 will offset this hefty bill ever so slightly...it'll probably pay for my head and that's about it.

 

[GV1390]

Woah, Cal and I agreeing on something....the world may stop spinning today!

But yes, I agree. While this will be getting tracked 100%, it wont be devoted JUST to track days. It'll see far more street riding for sure.

Wait, maybe I'm confused, by rods are we talking about connecting rods or forks? I'm talking about connecting rods, haha.

Not enough!

I didn't know GSXR rods fit in these motors. That's what threw me

Well, now you know!

[540nova]

 What's even crazier, to me, is spending $10,000+ to get an extra 10 HP out of the CB450 engine. Seems foolish.

That's what happens when you pay people to build you something....foolish indeed! Must be Canadian.

Too bad each of the rods weighs 39 grams more.

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.

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?

[Camrector]

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. 

[RAFster122s]

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.

[GV1390]

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!
