I have sort of a odd question, not a problem just something I seem to be noticing on my NEW 2010 GL1800.
Let me set the stage for you so you know where I am going with all this. Back in May of this year 2011 I bought my first new GL1800. Filled the tank and went out for a ride till I almost ended up pushing it to a gas station. I got about 350 Km ( about 218 Miles ) out of a full tank, and I do mean full to the point it was almost over flowing…!
Each and everytime I filled up I would set the TRIP to ZERO and when I needed gas I would fill up again and write the Km’s on the gas bill so I could track the number of Km’s and Litres burned…and so on. On average I was getting 350 to tops 375 Km’s per tank and I am easy rider picking up speed gently and not caving new grooves the road from corning. I did this gas useage and Km’s for the first 5,000 some Km’s and it always came back in that 350 to 375 Km range when the gas light would come on.
I have now had the bike 2 months and 8 days….I really thought it was longer but just looked at the papers on it….yup…bought it in May, brought it home on May 3 / 2011.
I now have, 14,700 Km’s on it, gee how can you tell I ride…just a little…LOL.
Anyways, I was riding and forgot all about how far I had gone, did not look at the gas gauge, and saw it was near empty and the gas light had come on. Then I look at my trip counter which I rest EVERY time I fill up….force of habit as my other bike never had a gas gauge and use the trip as my gas gauge. Now I look down and see what…? HOLY SH!!....I see it showing that I have clocked 415 Km’s on this tank when the light came on. I was freaked out…see I still had 35 more Km’s to do before I would have any hope of finding gas where I was at the time. I thought to myself….well you really screwed up now…now you going to find out what its like to push a wing to a gas station.
All the gas station where closed as it was 1am in the middle of nowhere…I made it home on that tank and in the morning I had to ride near 10 Km’s to the gas station to fill it up…I made it…!
NOW THE QUESTION… Have any of you ever noticed that as your bikes engine aged some from that of NEW….have any of you ever noticed that your getting better gas mileage as it aged….???? I have put it to the test on my bike now….2 tank fulls…and I seem to be getting into the 400’s Km range on a tank now…and not like 350 and running on fumes like I did when the bike was very new and had less then 5,000 some Km’s on it.
By the way I did the math on all the gas bills....which by the way I have saved from day one. If I put it in MPG numbers....when the bike was very new the MPG I was getting was 39 to 40....I think on one bill I just about hit the 41 MPG point.....almost.... Now...for whatever reason...the last two bills work out to 44.2 MPG 466Km if I run the tank dry ( 291 Miles )
Ok....so why the better gas mileage now....? Or if the engine broken in now...and thats why...? I did however for what its worth notice a slight change in the engine at around point where I hit the 11,000 or so Km mark.
As for oil....its Amsoil 10W40....and there Amsoil oil Filter. But then I have been running it on that ever since I hit the 4,000 Km point. Up till then it was factory oil in it.
