creature bret wanted to do this.
I was going to do that to my rigid. Still might. Brent

No Way! It is the real deal. Unless you did it.
not completely pointless. yeah, it's complicated, but running two carbs allows you to have a higher intake capacity while still having enough venturi vacuum for the fuel to be metered properly. 1 big carb wouldn't draw enough vacuum to work right. now whether or not that cylinder can fully use both of those carbs is a whole different story : \
I guess I would run two throttle controls, one on each side, and use just one carb, or one WOT and one half throttle to get better vacuum at lower RPM, and I had thought about doing this myself too. Hah, we all are trying to think of something that those Dutch haven't done yet. I'm assuming this is a picture from overseas, naturally.
i'm so trying this if u have 2 useless 12mm carbs u basically get a 24mm carb for the price of making the intake. of coarse tuning somthing like this could be a nightmare.
should they both run at the same time or should one slide move at a different rate than the other, should they be jetted the same??
lols
Looks nice.
And Elliot, 2x 12mm carb isn't 24mm. It's about surface area.
So: Pi R^2 = Pi 6^2 = 113mm2 per carb = 226mm2 for 2.
Then you get (root(226/pi))*2= 16.9mm
So basicly two 12mm carbs are 17mm combined.
And I don't know if it has any advantages. Sure looks cool.
Yeah, the intanke looks tiny at the part where the both meet. Cant be bigger than 17.
Of course we don't know the CC's or other specs.
I had a 1974 Peugeot car w/ dual carbs, second one kicked in at higher rpms worked w/ vacuum control.
Climbed up hills like a goat...
pointless
smells fishy
Just like your vagina.
Send me stuff please Lee.
awe man no 24mm carb yeah now that i think about it you can't make a 24mm hole out of 2 12mm holes o well i guess it is pointless.
i'd rather concetrate on other pointless things:
the power is in the points
Power is in my muscles.
I wouldn't say it was pointless. Eight 2 barrels on a Caddy V8 may seem pointless. But it was cool as hell. Same here. It can work. And how many others can say there ped has twin carbs.
actually the advantage to run multiple carbs is that you can have them working out of phase wif eachother so you can get a better fuel flow curve the same way that 4 barrel carburators work on a old v8 engine where you have primary bore which is pretty anemic for power and the huge secondarys that flow like it is dying of thirst..
I was thinking the same thing. You could have a "primary" and "secondary" venturis like in a car. Have one for part throttle and an extra that kicks in later and dumps fuel. But that doesn't change the fact that the Power is evidently in Mike's muscles, guess I've been looking in the wrong places.
true, now if we hooked rafter up to a giant wheel that used some sort of dual carb setup to feed him protein shakes i think the calulation of musle to moped ratio would.........
tommy are u building this or what cuz now i want to do it on my puch.
What about like one 12mm for super good low end response and one 16mm or bigger for all out high rpms? The 16 would just stay closed most of the time like a 4 barrel. The linkage would be a challenge. Now if we could rig up a heavy duty bicycle d
Well I guess the secrets out my new project. Step one obtain a Mike Rafter, Step three Speed. Eh....what was step two again??
Seriously though I was thinking the same thing about having a smaller "starter/idle" carb and a Main carb but it might just be easier to adapt some pre-existing 2 barrel carb to fit. For the linkage i was thinking that a setup sort of like a cable operated parking brake works but with one adjusted to open before the other. Or you could just make the second one vacuum controlled like a good old holley.
alot of scooters and nopeds have a dual action throttle cables which runs the carb slide and oil injector at the same time.
you could convert a choke switch to throttle control that could even double as cruise control for long voyages.. But theoretically one big (15% smaller than the intake port according to Jennings right?) variable venturi carb shouldn't really have too much problem maintaining velocity if you open it up slowly right?
yeah, the only way it would be cool is if it was set up to be a 'primary' and 'secondary' type thing. or if you wanted to do nitrous, and feed a second carb with nitrous and run it at super rich jetting. seems like a lot of fucking around to me.
Would be easy enough to run a left hand side as a throttle to control the second carb
I used to ride a 1939 indian chief with the throttle on the left...timing on the right...foot clutch, tank shift...(set up that way so you could shoot with your right hand...old cop bike) maybe better gains with dual exhausts one for bottom one for top...less risk for a lock-up, that dual carb single cylinder stuff gets tricky to jet at full speed...hope it works
WOW.
That's the coolest Tomos I've ever seen.
Hands down the coolest.
Fuckin' rad.
So, how well does the second RC Nitro Fuel carb make it perform?
If it's like it looks... hold on!
