Hey guys. I got a 2011 S40 stock, of a coworker of mine who bought it brand new in 2011. He rode it about 643 (exactly) miles and then let it sit for 5 years, outside, no cover. So far, I've had to clean out the front fender of the black widow and her 3 egg sacks of babies who decided my front fender and forks would be a great place for a play area after I got it home the first night, I've changed out front brake pads, battery, did a passable job at cleaning the carb, E336 spark plug, and I've got new front and rear bearings I just ordered this morning. I've put about 100 miles on it since.
My current issues are:
I'm constantly having to mess with the fuel/air screw on the carb it feels like. I've read the posts about setting it 2 - 2-1/2 turns. I've also read that the carb is super lean, so I've tried closing most of the way in. I'm getting a lot of backfire while riding, and smelling burnt gas. Is that normal or am I just making the typical newb mistakes?
Also, it feels like the engine is jumping, for lack of a better word. In 3rd gear and up, cruising with little to no variation in throttle, it feels like the engine is hopping, or misfiring I guess, randomly instead of running smoothly. Any ideas on what to check?
