When did you last have the carbs balanced ?
Never......cause its EFI
it's still needs balancing though - the throttle bodies need to be balanced, just like the butterflies on carbs.Originally Posted by Dan505
Both butterflys open sync'd guessing thats balanced right ?
Before doing any work to the bike, start from first principles and determine the actual fuel consumption ie fill the tank, then the next time you fill up record miles travelled and the amount of fuel needed to refill. Then it's a simple calculation of miles divided by fuel (litres) equals miles per litre and then multiply that figure by 4.54 to arrive at miles per gallon. Once you know the mpg, then you can decide if it is lower than you expect and if you need to investigate doing any work to the bike.
I doubt very much you could see the synch like this - it is possible to synch statically with feeler gauges but it's done rarely. The synch adjusts the amount of butterfly opening (or air bypass) when the throttle is closed. Since the engine is pulling against this very obstructed intake, it creates the vacuum and by matching these you ensure the butterflies are synchronised.
In my experience on EFI bikes, bad economy is often down to worn plugs or iffy ignition - injection is pretty bombproof, however it is prudent to keep the throttle bodies synchronised and it needs to be done as part of a normal service schedule.
