sand in airbox
Today I pulled the tank and airbox cover off my litre Strom as it's in the gargage for winter. When I took the air filter out of the airbox I was completely bummed out. The lower or "clean" half of the air box is coated in a fine abrasive dirt. The throttle valves and intakes are similarly coated.
When the dealer replaced the air filter last summer, his junior maintenance lackey threw the air filter gasket away with the old filter. Doh!
After checking the contents of the oil filter, doing a compression test and carefully inspecting the bike, it does not appear to have done much damage. The compression seems a bit low, but well above the service limit. I am guessing the valve seats may have suffered a bit. A leak-down test would confirm or deny this but I don't own a leak-down tester and don't really want to spend $250 for a good one.
Bottom line is the bike didn't blow up. Impressive really.
