hey 1200rc we'll see how much twin webers suck on saturdays cruise ... especially on a lowly 1200cc motor
looking forward to it even more now

my quad tb instalation will end up costing me less than my twin 40's cost me...

They are quad 38mm motorbike throttle bodies which I picked up for under $100AUD running with megasuirt on a custom manifold.

When its all finished it will end up costing under $1000 which will not take long to recoup, with the sale of my webers anda few months driving. I get terrible milage around town... which granted changes when Im on highway...

I agree with you webers are great when they are right... how many people have them right.... thats another story.

I dont see too many F1, rally or v8 super cars running webers... so I would like to know how they deliver fuel more accuratly than EFI.

I just do not understand how they can suck when most racers use them. Too many people wrongly set up carbs in my opinion then run them down. They were released on 1200SSS's with round port A12 heads so driveability must be ok with the know how. Carbs are just not appreciated enough.

You can still buy new Webers at a very high amount of poundage through various tuning shops such as Burton Power etc.

I'll wade into this argument too.

1200SSS had them because EFI didn't exist in 1972.

The Carby parts stores almost don't exist in Sydney anymore. Webers are an "endangered species".

Carbs are cool, and old school. But they just can't be better than a decent EFI system.

It's all in the tuning.
When Chrysler used triple webers on their six pack hemi engines, it took the gurus at weber in Italy THREE MONTHS to get them set up perfect. Granted, technology has come a long way since then, But I rode in a CA18DET 1200 race car, that couldn't catch a six pack charger around a race track. The bugger was really trying too. It was a frightening experience.

I hear that dellorto carbs are easier to tune.

It's true, I stopped at the kiosk and spoke with the owner of the company that's importing/selling them here in the U.S.

An Asian company has gotten the rights to use the Weber name on a new hybrid DCOE, similar to SK carbs in that they share the Mikuni design but use the Weber jets/etc.


BTW, in the Tech Article, ddgonzal states the Mikuni carb is a cross between a Solex and a DCOE, but I think he was thinking of SK's.

Asia hey? last I heard they were being made in Mexico

now i've thought more about what i was saying and what you guys said...........

bang for buck webers are just not worth it!!!

ive had everything on a-series except quad throttle bodies..... and by far webers were most expensive to setup, and to get them to be tuneed to some semi-decent compromise was going to cost a rediculous amount, so i went back to SU's and was very happy, that said i've seen twin webers on many a rally car that were "tuned properly" and still it always reminds me of mine, they run like shiat at anything but full noise.

typically it would be EASY to do injection for much less than twin webers, and i dont need to tell anyone the benfits of injection

and for the comment about twin turbo injected, dont you find it amusing i could do this to my motor for the same price as webers? sure there's some wank to it but it works damn well too - unlike webers

webers
chew too much juice
only run well at full throttle
cost big money to setup
require regular maintenance

it all adds up to big dollars, sure they give great max power, but power under the curve probably cancels out the benefits anyway

why not spend less on carbs and more on suspension or tyres etc.

1200rc, poorly setup injection will be just as bad as your poorly setup carbs were.

what I find amusing is how expensive and hard it is to set up sidedraughts!
I paid $250 for a pair of 40mm Dellortos from an Italian wrecker, brazed on a bit to the standard linkage because the 2nd hand $50 manifold spaced the carbs further apart than the Alfa they came off. and a bit of alloy bar to hold the throttle cable cost nothing. $150 to Carb Tech to have the chokes machined out to 36mm and jetted spot on. Ran smooth as from 2000rpm on the way to work to 8000rpm at Mt Cotton(no vac advance hurt it under 2000rpm, but you're never really there anyway) and idled at a nice smooth 1000rpm with a pretty wild cam - 304 degree duration and .514" lift.

I had them on the car for 4 years and never touched them - what maintenance?

I've driven (not just seen) plenty of other rally and competition cars with twin/triple sidedraughts and can tell you only poorly tuned cars have any driveability issues even with huge cams.

you should compare apples with apples too, not single TB injection with twin sidedraughts. The webers have more power potential.

extremely hard to believe!

what about manifold?, what about trumpets/air filters?

edit- when do cars with big cams run well under 4000 let alone ones with twin webers aswell?
