Quick fuel question

[ghwallice]

From idle to 1/4 throttle if one header is running hotter than the others, does that mean it is running leaner? Need a quick response....regards Greg

That would certainly be my understanding. 

 

[Laverdalothar]

Yes. Check Float and idle screw settings and idle jet isn't blocked.

Perhaps you could have a look at the spark plugs and see if there is any indication of mixture there. It may not be a reliable approach depending on time spent at other throttle openings, fuel etc.

I believe that you can get non-contact imaging thermometers that interface to your phone, could be a way of confirming actual temperatures.

That's a big ask a quick question

It might also mean the carbs are out of balance (slide heights etc) and one cylinder is working harder than the others...

What Laverda are we talking about and if it's a triple, middle pot or not?

And how's it running?

Fair to assume it has more than two cylinders. Unless it is a V6 (which I doubt) and assuming it is a Laverda, pretty sure it is a triple.

How much hotter in degrees? Measuring with an IR gun? Or just observing?
