Why is oil not draining from your 1500 suzuki intruder?

Oil may not be draining from your 1500 Suzuki Intruder for several reasons, including a clogged oil filter, a malfunctioning oil pump, or a blocked oil passage. Additionally, if the bike has been recently run, the oil may still be warm and thick, making it difficult to drain. It's also important to ensure the bike is positioned correctly to allow gravity to aid in the draining process. Checking for any potential leaks or damage to the oil system can also help identify the issue.
