Pinto on Bike carbs
At the moment I plan to use dellorto twin 40's on my 2.0 pinto as I already have them but they do need refurbing and more than likely new jets
ect. has anyone changed from this setup to bike carbs and whet benefits are there (if any) to doing this?
Also which carbs are thought of as the best and what should I expect it to cost?
1 other thing is what are these carbs like for getting through sva with emmisions??
Cheers. john

something to think about with bike carbs....
when you take your car to a rolling road to have the carbs/inition sorted, will they have the necessary part to set the carbs up?

R1 carbs are over-priced now. Lots of other bikes have the same Mikuni carbs so look at other options.
Tuning them is very easy as there are only 2 jets and they are mostly self compensating.

Im still not convinced that bike carbs will match a pair of properly set up webers/dellortos. What you have to remember is that a lot of people
experience flat spots with carbs because they arent set up properly, not due to an inherant weakness in the carb.
I would like to see some rolling road comparisons on the same engine of bike crabs vs DCOEs. That would be interesting...

The bike carbs are CV (constant velocity) with a vacuum operated slide. This opens and closes to keep the airflow through the carb at the optimum
point. The more the engine sucks the bigger the carb opens. The needle is also attached to the slide so the more the carb opens the more fuel it lets
out. This system will make up for a slightly wrong main jet size.
Also, because they are so simple they are much easier to jet correctly than DCOEs.

For example, by Bogg Bros bike carbs are for a modded 2L Pinto but run fine (all be it a bit rich) on my 1.6L Pinto.

so with that in mind, all these bikers that have there bikes put on a rolling road after they have changed pipes and airfilters, spending hours and
pound notes setting up there bikes are wasting there time and money because the carbs do it all for you?
so what has been done to your carbs to "set them up" for a 2ltr pinto?

Just increased the main jet size and adjusted the idle mix screws.

Going to fit a set of bike carbs on my crossflow when I've made the manifold . Hope to get away with drilling the jets out a bit at a time .
I've seen micro drill bits that go up in small increments but will they be small enough ?or is it still possible to get a set of jet drills?

the way boggs explained it to me was if the bike carbs can feed a 1000cc bike at 12000 rpm then they will feed a 2000cc car at 6000 rpm with little
adjustment, the r1 carbs for my v8 have the main jet drilled from 150- 220 to suit the 4.0 rv8

I have R1 carbs fitted.
I haven't done a comparison but what I can say is that with a 285 cam my 2.0 still ticks over smoothly at 850rmp and picks up cleanly without
any flat spots.
Economy is not too bad either if I drive sensibly. But them I don't have as much fun!!
