Averaging 43-47 MPG (2-up) with the TTS MasterTune on 2009 FLTRSE, no more popping after several V- tunes. Bike runs great but concerned it maybe too lean? Plugs are white.

yep. too lean. where did you get the map?

[Jimharry77]

Map downloaded from TTS MasterTune, after running updater

[LarryB]

do a couple v-tunes

Too lean ?? How can you tell ?? My old EVO that ran great had white plugs..  Try'n to understand, Thanks..  He mentioned after v-tunes   

[Jimharry77]

Not sure but 43-47 mpg on a 110 cu in riding 2 up just seems too good to be true? White plugs indicator of running lean. I've run the V-tune program six times.

43-47 is to good to be true, exactly. are you turning all the cells green when v-tuning

Not necessarily.  There are tons of variables that effect mileage.  Speed, weight, altitude, temperature, wind, on and on and on....

Here is an interesting comment regarding mileage...

I find with my 120, that riding two up and pulling the Bushtec and all other variables being equal that 75mph is the magic number.  Ride faster than 75mph  (75+ to 80mph) and my mileage drops to 35/36.  Ride slower (65 to 70mpg) and I'm at 44/45 mpg...

jinharry77, My plugs look a little white based on all the other bikes I have had, but I just got back from a 3500 mile trip with passenger, and luggage and the bike ran fine. No pinging, no popping even from St. George Utah to Las Vegas ( not recommended this time of year it was 110 degrees at 7:30 the evening). I have attached a page from my 09 service manual regarding spark plugs and color etc. CAHDBIKER

I generally find the same to be true, Scott.  Seems that the 3K rpm spot is where they really start getting poorer mileage.  If I get 40, I'm fine with that...anything above is gravy.  In really hot weather down here, mileage suffers regardless.  The air is both hot and wet.

Thanks for the service manual attachment...picture is worth a thousand words...I don't have pinging, popping or any other problem indicator. Probably run one or two more V-tunes and be thankful for great MPG.

only way to read a plug is to run wide open  6th gear and then kill engine, then take plugs out and read them, poking around town and pulling plugs out will not tell you a thing, plus w/ the fuel now days its hard to read a plug,

.
how much of the map are you leaving in closed loop,after your done v tuning?
what did you set your closed loop bias to.
running closed loop even with CLB turned up your never going to be any richer than 14:45 AFR.
so if you leave the map in closed loop everywhere,as you had it set up for v tune.
then sure it is lean. 47 mpg two up would scare the chit out of me. Unless you were in 5th gear @ 55 mph drafting a couple other bikes.

[Jimharry77]

Left the bias to the default 566, etc. Also reset AFR table after final v-tune. However, do you reset to original AFR setting before merging v-tune and creating a new MAP or after?

@ 566 CLB your setting AFR around 14.65.
not sure what your asking? you tune to closed loop at whatever CLB you have set. that is the only way v tune will work ,it has to be in closed loop so the stock NB sensors are active.
after the v tuning is complete,(you feel that all the areas you can reach are filled in . ) now that the v tune has been generated and the ve's have been calibrated,you can change the AFR table to the AFR you want. 14.6 is the target you use for closed loop, changing the AFR to anything less will put it into open loop.
if you are wanting to stay in closed loop in some area,I would use .798 CLB setting. this will get you about as rich as you can be in closed loop. I have never seen CL any richer than 14.4 no matter what the CLB setting was.
I guess the answer is after if I understand you right.
