Bike Carbs over Weber Carbs

[dacar]

I know this topic has been covered at length but looking for advice on whether to go for bike carbs over a set of twin 40's or 45's for my 2.1 Pinto which is currently running 32/36 twin choke(and running fine).I read the article in the current Classic Ford and started thinking about bike carbs. So just want to hear bad or good stories. Cheers

bike carbs are for lightweight vehicles like bikes there ok flat out but dcoes are better they have pump jets for heavier vehicles to give them get up an go plus dcoes look far better under the bonnet of a oldskool imo

i originally run on 45's but was never really happy with them, got a set of FZR750 carbs on a bloggs manifold. runs great, starts on button with choke, ticks over evenly, revs well.

 

webbers would cough under 2.5k-3k but then fly, bike carbs just went really well without being temperamental.

webers all day long any coughing is down to bad set and jetting

[Fiesta Steve]

As said above, poor running webers is down to poor set up and no accelarator pump on bike carbs means you'll never equal the accelaration given by webers although the same misleading peak power reading will always be given on a rolling road.

 

Depends what you want from your car really, if you want to go fast use webers, if the other things bother you go for bike carbs..

I have had both bikes and cars.Carbs for bikes go on bikes. Webers go on oldskoolfords.End of.Not up for discussion.If you want bike carbs buy a Honda.

Thanks for your thoughts people and I sold a Honda CBR1100 to purchase the RS so weber looks favourite.

Then theres the sound ..... webers all the way

Got R1 carbs on mine, love it.

 

Set them all up myself and runs spot on, it ain't no racing car but if I had the money I would go weber 45's but I bought my carbs and all fitted done for £250.

Hi, new to the forum with a MK2 RS2000.

Just read this post and curious as to what you went with finally and how they perform?

Bike carbs do run fine BUT Webers will make more power. Its been proven on the dyno. Simples

If money is no object go with a set of 45s, stay away from 40s on a 2.1, cant get the chokes big enough. 

I've had both fitted, 45s were great for the power, but require careful setting up and regular tweaking, if not they will spit and fart on part throttle, bike carbs are pretty much fit and forget, and much cheaper. If you fit Mikuni bike carbs, you can use weber jets - direct swap, Keihin carbs require a bit of drilling and tapping etc to get the jetting spot on.

 

Whatever you decide, get them set up properly - fuel stand off, the spitting you hear, causes fires. The money saved scrimping on set up costs will not replace your pride and joy.
