Gee, Did you get 40K miles out of just three sets of tires..Lucky you.
Your buddy; Did he get 80k miles out of two sets? Maybe he bought the bike used and the two sets of "shoes" are what he has put on since buying it? 80k for two sets is incredible and UNUSUAL.
Easy to install fuel filter..Also, I use Seafoam additive to gas every month...a couple of ounces in a tank of gas is good.
You might consider buying a premium quality chain/sprocket set up in case you have been using economy ones.
I don't mean to diss your comments, but I see your bike as being average or a bit better in dependability.....to compare it to just one bigger Honda is not a broad sampling..
