Would you run four different heat range spark plugs??

nickjtc · « **Reply #2 on:** August 21, 2006, 12:54:28 PM »

It would make balancing the carb sync really easy!!

The only way that could possibly work is i there was a super or turbo charging that, uh, pipe thingy, with lots of positive pressure. I can't understand that mikuni would design such a thing, otherwise...

Looks fake to me, like he had a mikuni sticker and put it on a homebrew intake, but what the heck do I know $:-\$

nickjtc · « **Reply #7 on:** August 21, 2006, 01:56:23 PM »

But if you go fast enough the fact that the carb is facing forwards means that there will be a ram-air effect..

Just kidding.

This is exactly what I thought when I saw the auction.

Same here. Just because someone put a Mikuni sticker on it, doesn't mean it was made by them, or does it?

Maybe it's like with the Honda Civics. Put some racing decals and an aftermarket wing on the back and suddenly they're really freakin' fast!

Among other questions I'd ask is how the hell does that single carb flow enough air to feed four cylinders, especially if the engine has been modified? And what's the vertical tube for? Interesting
piece though..

You talking about the brass tube on the side of the carb? That's the fuel inlet.

I beleive that's for an old turbo setup. Fuel and air get stuffed into the side pipe by the turbo on the front side of the motor I remember seeing pics but I can't remember who made it.

So, what's it like to ride? I remember when they were first launched it was highly under rated, living in the shadow of it's 550 and 750 siblings.

ElCheapo · « **Reply #16 on:** August 21, 2006, 11:17:57 PM »

I think it is straight CRAP. Like the mouse on my computer that starts and stops when it likjes to. Just think to this one fact, How much gass will cylinder #4 get? Yea you can run a car on one carb, but the mutha fer is in the middle of the runners!!!!! Not this home job garbage. Also, the main jet would have to look like a freakin straw hole to keep up. No mikuni in the stock body can keep up with 4 cylinders of air flow.

This unit is junk....

That's why it's for a turbo setup. Has a fairly large plenum running across all 4 cyls, mixture is under pressure so the intake length isn't too important. I bet turbo lag was bad though.

WHY OH WHY are people always trying to "get over" on the 750 engine regarding the carbs?

People go for this "one carb/two carb" crap, as evidenced by the fact that people actually bid on this piece of crap and people buy the Cycle Exchange carbs.

WHY?

?

It has FOUR carbs for a reason!!! Soichiro and GOD himself said the Four-cylinder Hondas are to have FOUR carbs, so they do. If the engines were meant to have ONE carb or that silly TWO carb set-up, Honda would have done it from the beginning.

Try to outsmart Honda's engineers? Doubt it'll work...

Yes. I've rebuilt and synced my current carbs.

On my forthcoming projects, one of the things I am actually looking FORWARD to is the tuning of the carbs for the velocity stacks and Yoshima pipe.

I LOVE experimenting and trial and error stuff like that. It plays right into my meticulous nature and Obsessive personality.

For some, these bikes are a hobby. I eat, drink, breathe and LIVE for my machine. It IS the driving force in my life and the ONLY thing I get out of bed for in the morning. Yes, I am THAT unhappy with life, that a 30-year old Japanese Machine is the ONE thing keeping my sanity in check.

But then again, it always does feel so very good when things go right for a (rare) change. So I guess I can feel where you're coming from Ghoulie.

After all, I am going after a Norton next... Call me a masochist, but I'll be one of the few masocists with a brit bike in Nashville

Good luck with that, Dan! Unlike the Honda, a Norton is a harsh mistress who will make you cry at the slightest provocation, but will also reward you with the most fulfilling 'rapture of the ride' possible......and I've only put a few hundred on miles on mine!

You could trash the carb and use the tube on the intake side of your existing carbs for an alternative to the stock air box.

OK, Jonesy, enough already with the stereotypical 'leaky Brit-bike' jibes!! The motor on my Norton is as tight as a ducks bum. No, the leakage is the heavy weight oil that is mandated for use in the swingarm (grease is verboten)....!!

I love Nortons. In fact, a 750 Commando is what I set out to buy, but the prices (among other things) drove me right over to the Japanese bikes.

Sorry, couldn't resist. There's a guy who brings his Norton down to the local bike nites and it always has a puddle of oil under it...

They're both watertight so it's all the same!!

The good thing about the passage of time vs. Nortons is that there is now a plethora of information available on how to make the motor keep the black stuff on the inside. Unless the guy is just waiting until he has to deal with the leaks (the most common is around the tach drive take-off) he should be able to fix it now.

DammitDan · « **Reply #35 on:** August 25, 2006, 03:18:03 PM »

Well, the way I look at it... I'm going to cafe a '72 Norton Commando 750, and I want people to say, "What the hell is that?"

I'll say, "It's a 1972 Norton Commando cafe." And they'll say, "Norton, never heard of that" as opposed to "Oh, a Honda."

You gotta admit, Brit bikes (although tempermental and leaky) just have more prestige than Jap bikes when it comes to the unwashed masses

All I can say is that whenever I am out on the Norton I have to allow double the usual journey time to get where I am going because every time I stop someone comes up and starts reminiscing about an old bike they used to have....can be any make, Brit or American.

When I'm out on the Honda I allow that extra time because the people who come up to chat used to have a Honda.

Two completely different mindsets, with the former usually being really old farts (my age or older) and the latter usually being my age or younger.
