Re: Darn Mice!
I got the mess cleaned out and cleaned/lubed the K&N that was in it. I took it for a test spin, expecting a dramatic difference in performance. Well, it was significant, but not dramatic. Like I said, it was running really well even all clogged up, somehow. It pulls stronger in the mid and top end, maybe 20% stronger.
I corresponded with the previous owner who I bought it from a few weeks ago and he too was shocked. He hadn't noticed any odd behaviors or performance issues. I believe that the nest may be several seasons old, likely before he bought the bike.
I'm absolutely amazed it was able to run like it did.
