now forgive me for being stupid but i can't get my head around setting up my bike carbs!

ive got my engine, my cbr1100xx carbs, fuel pump, and fuel tank, all seperate from each other, what is the minimum i have to do now to get the engine running?

obvioulsy i need a manifold and fuel lines, but what else?

any help would be greatly apreciated!

Cheers, Theo

they say bike carbs need proper jetting to suit your engine...

all you need to do to get the carbs to work on a car engine is change the main jet to 1.6-1.7mm .

Go down you're local model shop and buy a 1.7mm drill and enlarge them yourself.

Mine work fablon

They have to be set to the specific engine. The main jets will have to be changed for larger or smaller ones and the needles need to be moved up or down using a clip and the several grooves on the end. If your needles only have 1 groove, you'll need to get a dynojet kit or similar.

Put simply, you need to select a main jet size so that your engine gets the right amount of fuel at full throttle at full revs. You then set the needle height to get mid revs and part throttle right. You then adjust the mixture screws to get low speed / low throttle and idle mixtures right.

The best way to do this is on a rolling road, though that can be expensive. You can do most of the work yourself by driving the car on empty roads to get yourself close, then just go on the dyno to get it spot on.

What you need is someone with the same engine and carb setup as yours to tell you what setting they use. You can then take them as a starting point.

If you're using a bike engine, just hook up the carbs, the ECU, pump etc and fire it up.
Make sure you're getting fuel to the engine, check the a spark plug against the engine body as you turn it over to make sure you've got sparks. If you've got fuel and sparks you should get it running...
Often people get caught out by things like neutral switches (so you can only start the engine in neutral), tilt switches (so you can only start it upright), bike stand switches.... But all these do is prevent the sparks from happening.... So if you've got sparks you know this isn't the problem!!!
Jetting will no doubt be required to fine tune but the car should run on standard jets at least...

ok thanks guys, much appreciated

is there a book that i could read to get the basics on this sort of thing that anyone knows of?

Once you get it running, I suggest that you take it to a bike specialist for balancing and general tuning. I found it impossible to get the engine running smoothly myself, and the £200 was a good investment!

First what engine you using ? pinto ? zetec ? bike ? this will help us help you
