Thanks for the tips on the wheel lock, that makes sense.
Ha ha, yeah I've done that a few times on my KTM too. But the fuel was on, so unless the fuel was bad or something was plugged should be good.
Will the bike start with a dead battery? Or does the battery need to be good for it to start? I've ridden newer bikes with dead batteries, but not sure what this one needs.
Next time I go up there I'm going to take my compression tester and I'm going to buy a new/spare spark plug in the meantime too. If it has good compression and good spark then I guess I'll have to tear the carb down and see what's going on. The CT90 guys talk about boiling the carbs in distilled water, CLR, and even Pine Sol, which I've never heard of before. I have some Berryman's so probably will try that first, or maybe even just gasoline to begin with.
