Hi there, new to riding, new to the forum. I appreciate any advice available. I was out of town for 4 weeks, left my DRZ with someone, the battery died and it sat there. When I got back the pilot jet was clogged. I cleaned the carb and changed the gas and oil. It ran fine for 2 days. I tried to start it this morning and the starter rolls really slowly and labored. Tried drop starting it (which normally is quite easy) but even with lots of momentum and weight the back wheel will not roll and I skid to a stop. The engine just refuses to turn. There was no seizure while riding, no traumatic clanking noises. What should I look into next?
