Hour Meters vs Miles

Ok, so I'm a little off topic here... My two other bikes don't have odometers, and I just installed hour meters on them. Any advice on translating the manual's maintenance mileage numbers into hours? One upon a time I used to ride quite a bit and would just replace oil/etc twice a year or so. Now, it is a rarer occurance (new baby), so I'm hoping to use an hour meter to better keep track of things.

Hey MXMann... You must have challenged thought here.

Nice choice on bikes.

My recommendation would be to go out on your average ride (maybe even using the CRFx that has has an odometer) and ride for an hour and note the miles.

Do this two or three times (more if you like) and average the MPH and simply use that as your basis-of-estimate for the hour meter.

Good idea. I removed the ODO on the 450X, but I could slap it back on or just fire up the GPS on my phone for a day.

BTW, that is quite the fleet of bikes you have! I thought I was doing good with 3!

EDIT:
Just realized there is both a standard maintenance schedule and a competition schedule in my CRF450X manual. The regular schedule says every 600 miles. The competition schedule says every 15 hours. I guess there is my answer! While I'm not beating the heck out of my X, like it would if I were racing it, 15-20 hours is probably about all the riding I do in a season these days!

Even if you don't put many hours on it, I would still think changing the oil at least once a year is a good idea.

Agreed.
