Topic: 76 550 top gear rev problem

80 miles using 3.76 gallons is 21 MPG.  Did you drive on and add miles after switching to reserve?

The owners manual states the tank is 4.2 US gallons including 1 gal in the reserve supply.

That's pretty sucky mileage for a cb550, imo.

For comparison my all stock 76 CB550F gets pretty near 50MPG on a road trip through the twisties.  My 77 Cb550 is quite similar, though I haven't calculated it in a while.

Do you turn off the fuel tap when stopped?  Sure you aren't leaking it out somewhere.  If not, check your spark plugs for soot.

I have plenty of bikes working on pods and run just as smooth as stock. It takes a while to learn how to tune and many people give up way too quickly.

I too believe it's possible to get a bike to run on pods, BUT, only a dyno proves that to be true. And I have yet to see anyone provide a dyno graph to prove pods run as well as, or better than stock air boxes. So, take it with a grain of salt that a bike is running "as well as". Because the very nature of the change is well documented to negatively effect the performance versus stock induction.

I have both a stock intake system and pod intake on cb550's and so do my friends and we constantly race. It is no better or worse I can hop on each bike back to back and won't notice a difference. A dyno would be a waste of time and money.

But, it would back up your brag.  Just sayin...

You know, a simple 1/4 mile timed measurement for each of your bikes is pretty easy to do.

Then just compare that to stock performance numbers.  It would give you a benchmark.
