Bike carbs...what do they do?

[twistedblack69]

I just google'd to try and find a description of what they do, even though I'm sure I found one a while ago, I couldn't find anything

Basically what I was wondering is what benefits are there from running on carbs? MPG suffers, right? But roughly how much? Do you need to fit a choke, like the old carb engines? Was thinking of putting carbs on a 2.0 16v ABF, what kind of power gains would I expect to see?

None, but you'd see a sh*tload more fuel wasted!

The 'benefit' of bike carbs over a traditional carb set up is that there is effectively a carb per cylinder and a choke per cylinder, so far more air should get in.  The flip side of this is that you effectively have four carbs to balance and set. 

It's such a bodge way of fueling in the days where you can use proper electronic stuff to manage fuel delivery, spark et al that it really is a wonder people keep flagging it up.

Fair enough. Saw some vids on youtube and it sounds pretty nice...maybe when I'm rich and famous and I have money to blow, I'll do a carb set up lol

You will see a gain in power, but not much, they're mainly used as a relatively cheaper way of increasing torque, which they do well. I think they benefit smaller engined cars more than they would an ABF.

they can give inpressive results if done right if done badly there a bit rubbish

Modern injection systems ftw.

Get some individual throttle bodies made up, they sound twice as nice

A friend of mine has r1 carbs on his kr sounds awesome but there hassle setting up and over winter serious carbs freeze other than that can't fault them easy enough to do and the scene queens will be happy if that's ya thing lol

Better off changing to standalone efi. Setup well, 180hp is possible on standard engine.
