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.

BUMMER
So what was the outcome, a whole new engine sound's about right given the possible and probable wear from unfiltered intake but I'm guessing he wont be too obligeing, in which case a letter to Suzuki might be in order. Dought they will do much except maybe drop him as a dealer and then blame any future problems on the past incompitance of a bad dealer and therefore not there responsability or am I being too much of a cinic, bit of a no easy win situation but most countries have better protection law's than Australia so you might get lucky and win :(

The first time I changed the filter on my bike I noticed a little bit of extremely fine dust in the lower half too. I think that the stock filter does let some super fine stuff through. There was no breach in the seal.

You should see how much junk gets into the bottom half of the airbox if you put the filter back without the seal. I have some pictures of the debris that will curl your toes. I don't think some fine dust is bad but sand, bugs, seeds, and various bits of plant matter have no trouble getting into the the air box "clean half" without that critical seal. Eeewww.

Ride well!
