Fuel consumption on a750 Big

[Captain Cook]

Only getting 13 km to the liter.  Is that normal?

No.
Check carbs.

How does your bike run generally. Mine splutters and surges at bottom end, lags and then pics up if I open the throttle. And it does not want to idle so well. Very annoying.

So I'm wondering is it just the settings or a good carb clean out. Bike did stand for a long time.

I reckon a good Carb clean-out is a good start. Often when the bike's been standing a long time, the fuel goes vrot in the carbs, and leaves a deposit of gunge in the float bowl. This causes all sorts of problems... from poor starting to lagging and bad throttle response!

Starts and runs easily. just the bottom end lagging and throttle reponse.

Mine runs like a dream just a little thirsty it seems.  Can be a little hard to start when the weather is cold but if I crank it twice with the choke out and push it back in it sorts the problem out.  Shoots a nice big blue flame out the exhaust when it backfires
