Huh. I put 10k on my first moto in the first 10 months. I think the Wee is up to 4-5k since I bought it in February, and I don't even have a commute (2 miles, I usually ride my bike instead of using a motorbike or car).
The weather here has been total crap all year, but when we get a clear weekend, my friends and I like to hit the hills. 200-300 miles in a day is pretty common, no freeways (meet for breakfast, be home by 3 or 4pm). If it hadn't been raining nonstop all year, I'd have put in a lot more miles thus far.
I don't really know what to say -- just ride it! Traffic is one of the best reasons to ride a moto here, but I guess if splitting wasn't legal I'd change my tune on that one. I can't fathom how people can sit in traffic on a motorcycle, of all things.
Load up your topcase (if you have one) or tankbag with a change of clothes, and hit the road for the weekend. It's easy to find cheap motels for $40 or $50 a night even in CA, split a room with a friend, it's hard to find a cheaper way to have a good weekend -- or go camping, if that's your thing.
Now, my car just sits in the garage, I have driven it maybe 3000 miles in the past year. The last tank of gas took 2 months to go thru, and it has a tiny tank and gets crap mileage!
But who am I to say you're not enjoying your motorcycle? You enjoy modding it, and you enjoy riding it. You say it seems like you ride it a lot -- so what if it's just short trips around town on the weekend, seems like you enjoy that. If it doesn't sound like fun to go out of state to rack up miles on the weekend, maybe that's just not your thing. There are plenty of people who have a fun car that they just use for running errands when it's sunny out, no reason the moto can't be the same for you.
