Well, after about 4 months of great riding, my new used bike left me stranded 9 miles out in the desert...but that's another story. Any idea why the engine would lock up? Neither the oil nor the coolant was hot after 3 hours riding in 75 degree weather, and the bike had been running great all day. Never sounded bad either. Kick starter won't budge, and neither will the engine if I try to push start it. What do you think - bad oil pump/water pump? I'm skilled mechanically, but don't have lots of time to devote to a rebuild...any idea how long it'll take? Is it as hard as the Clymer manual makes it sound? I saw some conflicting info: one statement said the jug couldn't be bored, then it recommended "reconditioning" if out of specs? Thanks in advance...really appreciate all the great info from y'all on this site!
