Just bought my first XR400- plated to go dualsporting with my friends. 1999 model, GREAT shape. Kept out under a tarp for years. Wouldn't start at first, but cleaned the carb, now it starts. Problem is it always takes LOTS of kicks to get it going.Very exhausting! Last time I had to use starting fluid spray in the airbox (started first kick after that). But once it starts and warms up, it starts great after that. Any advice???
