motorcycle carbs on sammy

[flmanyj]

mabye a KZ1000 or some bike that has 4 carbs

i know they will run on there side becouse my bike still runs when i lay it over


any pics


any one try it

[Erik Dossett]

You mean while riding? "down" leans over with you, to counter act cornering forces. Or do you mean it runs when you drop the bike on its side, as in fell over (we've all done it).

A friend of mine uses four Ninja carbs on a custom made intake for the 1000cc engine he runs in his LJ 80.

We need pictures!!!! I have been chasing around a guy on another one of the Suzuki boards about this same subject!!!
Please??? Pretty please????

[jones]

I have no pics. I can try to get some and email them to you later. I can describe the intake though, it looks easy to make provided you can weld the aluminium. At least he used aluminium for his. First a flange was made to fit the head, and round tube the same size as the carb's venturis was used for the runners. Then he made another flange which allows the carbs to bolt to the runners. Really simple actually. I posted a quick sketch here if you're not following what I'm saying.

With years of experience running roundy-round cars that used motorcycle carbs, I'll warn you. One of the mojor problems is the fuel pressure. Motorcycle carb are designed to be gravity fed. The needle and seat are large, and don't take positive pressure from a pump very well.

This can be a major stumbling block when you try to get it tuned out. Flooding may become a problem, and negate any benifit to this kind of setup.

all the newer bikes in the last 10 years ive tore apart had fuel pumps,,,,, they dont have returns though they pump to pressure and die then slowsly start again ect ect..

[smitty808]

The pressurized fuel system isn't a problem...run an electric pump, into a fuel log...4 outlets to the carbs, then a return line to the gas tank. You could control the pressure at the carb by changing the restriction on the return line. Simple, cheap, effective!!
I just wanna' see some pics!!!!!!!

Why go through all of this corn cob technology when there are bolt on factory efi units that would be easier, cost less or the same, and work perfect?

Its 2002, say good bye to carbs and enjoy modern life...angles, altitude, no problema!

[poppycock]

we fear change

[Erik Dossett]

Efi is great, but I doubt it would be as cheap or simple as a set of junkyard bike carbs - not that I would do it, I think it might not be so good for bottom end power. Me, I like the low end so much I went to diesel anyway. Did it ever get determined if the bike carbs would handle running sidways? I know they work pointed up, look how long bikes can wheelie. Just that they don't usually deal with cornering forces - a leaned over bike in a corner still sees "down" as under the engine - the lean is counter-acting the cornering forces. Anybody running a bike powered buggy or anything? The only times I have dropped a bike I ended up killing the motor too, or at least picked it up right away, so no side running testing done.

I think it might not be so good for bottom end power.

Uhhhhh...I doubt it. Do you really think motorcycle carbs and intakes are set up for torque??? When was the last time you saw a Ninja towing a trailer up a hill at 1500 rpms? They are set up for revs and HP.

EFI might not be free or a 30 min. job, but by the time youve fabbed a custom intake, linkages, cables, synched carbs, fucked with jetting for an eternity, and then trouble shot the whole mess (and god knows what its go to end up like?) you could have bought an 8v efi setup for $200, installed it, drank a lot of beer and gone to the con 5 times.

I used to see dipshits on topica go an for EVER about those Nikki carbs. IMHO a carb off some 20 year old Puegot, or four carbs off a Ninja is going in the wrong direction.

Thanks for the vent!

[bobaki]

WHAT HE SAID!..........scawfish,that is.............

[flmanyj]

what about a harley carb

[scwafish]

Yeah why not...they're about the only thing lamer than an old Puegot carb. My brother had about 5k into his Fatboy motor and it idled like a tired lawn mower...PERFECT for wheeling. BTW even the retro retards at Hardley Ableson are going to EFI.

[Rockrat]

I argree EFI or leave it stock

Ya, like I said. However, this has lot to do with cams, ignition timing, etc. Gold Wing use one carb per cylnder, and do pull trailers up hill - not likely at 1500 rpm, but the stock 1.3 is shite at 1500 already. Perhaps someone who is interested in revving the motor to death would like to try to do it really fast.
You really pull hills at 1500rpm with a trailer? Not even with my diesel do I like to pull that hard, that low - I can, but it's too rough. I usually rev up to about 2000 or so.

uhhh......isn't this the PIRATE board....????

Change is what we crave.

Hacking the shit out of these trucks is what we do.

And why not do it?...if you've got the time...mods are how we learn....what you fawk up....we won't later!

I think we're all ears here...


go on man.....
and Goodspeed to you

[scwafish]

Yep...I really wheel my sami at 1500 rpms and all the way down to idle. Its called gears and I really recommend them for rocks.

As to hacking vehicles, hack it only to make your rig WORK better...maybe you are confusing this site with junkyard wars

[Erik Dossett]

If he wants to hack it, lets learn from it. Lotsa' guys doing fuel injection, if someone makes something else work we can all learn from it.

Let me say I like fuel injection. Anybody who wishes "for the good ol' days" of when "anybody could work on their car" is forgetting what a pain vacuum controlled carberators and points ignitions were like.

And let me say yes, low rpms are what I use all the time. But if someone can make a high rpm dune-running owerhouse,well, that's interesting to me. Not my thing, but interesting.

Good advice to send people to fuel injection, no doubt about it. I would just like to try not to squash innovation by poo-pooing someone's ideas, no matter how goofy they seem. Ok, let them know it's goofy, but we can still consider the ideas.

So, back to the original poster .... do those carbs work sideways as well at tipped back or forwards ? Just for information, I don't plan on converting my diesel to a multi carb gas motor any time soon. Come to think of it, on a Sam they would be sideways to their "normal config" when the rig is pointed up.

[scwafish]

I agree with Erik....so if you want to waste your time you $$$ and be a dumba$$...Go ahead! I'm waiting to be entertained

[slider]

scaw...

Junkyard wars...

I saw an episode the other day...it was all American!!

Did the beer go to my head or is there now an American version?

[Erik Dossett]

Yup, they have American episodes. Imagine the rig a crew from the Pirate could whip up.
