So here's how it went down.
I was on my way to school this morning, in the carpool lane doing about 70mph when I noticed my rpm's were a little high for the speed I was going. I didn't think much of it, because I was heading into a 30+ mph headwind. Anyway, a few miles later, and about 25 miles into my ride, the engine just totally bogged down, like I had run/was running out of gas. But I wasn't! I had a half a tank still!!!
Now, I am left with a bike that runs fine, revs fine, even runs good on the stand. But any time I try to run it on the street (i.e. under load) its will be fine to about 20 mph, then just bog down. I still accelerates, but about as hard as a 50cc scooter, though I can still reach higher speeds like in the 60+mph range.
Any ideas? The only things I've done to the bike is a 15 tooth front sprocket about 3 weeks ago (other than maintenance). I'm thinking of just taking it to a mechanic, but I want to see if it might be an easy fix first.
So in summary the symptoms are:
-bogging at speed
-runs fine unless under load
Any help would be greatly appreciated!
