First off, got my P's yesterday! Feels good to finally get the yellow monkey off my back. Now about a week ago, i started to notice a rattling fromt he engine block; only audible in first and second gear, at high rpm. Not audible in Neutral or stopped dead. I got the bike serviced on Thursday from the boys at Close motorcycles, and asked them to look into it. They couldn't figure it out without having to open up the engine, which will cost manual time. But they reckon it shouldn't be an issue. What do you guys think? Personally it bothers me that noise wasn't there last week, and i'm tempted to rip apart the covers just to see if there's anything loose or broken. The thing is, especially after the service, she's running better than she's ever ran before. The noise sounds like gravel had gotten into the engine block / valves. Imagine a noise of sprinkling gravel on metal. I believe it is a concern for worry despite what the service guys said. She's an Intruder 250 BTW. Thoughts?
