I have a couple of quick questions that are making me ponder.
Firstly, the easy one. I have a Dunlop Sportmax GPR-100 rear tyre. Now this tyre was fitted by the previous owner and since then has done in the vacinity of 14000kms. Now, unfortunately because I ride 120kms a day just going to and from work, I do a lot of straight riding.
The tread depth in the middle of this tyre is approx. 2mm and I'm wondering how many more kilometres I might get out of them.
Does anyone know the tread depth on a new tyre?
Anyway, the second question regards fuel economy or lack thereof.
My fuel economy is seemingly in slow decline. I was getting 19kms+ per litre, and my last tank was 17kms/L.
Now, I'm wondering if anything is wrong, or could be corrected. I've had the bike for 5mths and 11000kms. (33000kms on the clock) I've done 2 oil changes, using Motul 7100 full synthetic, have a K&N airfilter, Iridium plugs etc.
So, the easiest things to consider are:
a) I'm 'getting up it' more as I'm so familiar with it now. (accelerating harder from the lights)
b) The SpeedoHealer has stuffed something up. (I have considered the correction of speedo error has obviously had some numerical impact, but I've lost more range than I think this explains)
c) Ambient temperature. I rode to work this morning at 0400and it was 1°c, so I'm wondering if as it's slowly coming toward Winter, maybe that might explain it? (19kms+/L was toward the end of summer)
Do you who live in Winter climes see a dramatic difference in fuel economy?
On my next days off, I'm going to pull the battery to allow the ECU to recalibrate and whilst I'm at it, I'll check the air filter. (6000kms old, but highway only, so no/little dust)
Anyway, I'm looking for suggestions, if any avail themselves.
Cheers,
Rick
