dirty intake

I have made the ultimate mistake. I went to check my air filter and my air box was filthy on the clean side. Full of dust and little particles. The butterflies are also dirty. Turns out I'm missing the filter gasket. I never checked for that when I bought the bike. I bought the bike with 14k miles, it now has 20k. So at least 6k miles with no gasket.
The bike still runs very strong, I have not noticed any reduction in power or fuel economy (48 Mpg). The po ran amsoil synth, and I do as well. The oil was just chgd about 2k ago. I will be installing a new filter with gasket ASAP.

Question is, now what???? Should I do anything else other than routine mntc?

Thanks in advance.

I'd throw in another oil and oil filter change, get the gasket and a new air filter, spray the butterfly valves with carb cleaner and wipe out any residue.

If you're getting 48 mpg, which I can not, I wouldn't worry too much. Keep your eye on the oil level as you burn up the miles.

Wait a sec, 48mpg? Maybe I should take out my air filter, lol. I'm sure this is an unadjusted figure not taking into account the dreaded 6-10% odometer error?
I know, I've been amazed myself. Not sure about the "odometer error", I plug in the miles and gallons and fuelly.com does the rest, great site by the way. I'm in there under "melonbuddy".

I guess this is the gas mileage you get when you don't have a filter gasket... great for MPG, bad for engine.

Understand that the SPEEDOMETER is 6%-10% in error. The ODOMETER is pretty much spot on. I know this because I've compared it to my GPS!

My Vee regularly see's 48-50mpg and it's all stock other than a K&N filter. I'm also tipping the scales at nearly 300lbs geared up and my bike always has the luggage on it.

So at least 6k miles with no gasket.
what kind of ridng, mostly pavement, its likely most of the dust is pollen not very abrasive and combustable, dust from a dirt/gravel road can be abrasive I have never personally observed and engine ruined from dirt road dust, but I'm sure it happens , I have observed an engine ruined from winter dust, dust from winter riding is usually deicers & sand, very abrasive and corrosive

obviously yer 6k isn't in winter or at least most of it, salt dust can destroy an engine with no air filter in just a few thousand miles, many years ago, a friend of mine rebuilt (new pistons rings, jugs) a VW Beetle engine around Thanksgiving, he commuted 60miles round trip highway and probably did half as much rural northeren new england winter driving, by mid February he new something was obviously wrong, we pulled the engine and tore it down, the combustion chamber looked as if it had been sandblasted,(piston tops, head, valve heads, stems, seats top half of jug was scored) there was grit in the oil, all because the air cleaner element got left out

just missing a gasket would take a lot longer probably, I doubt you have anything to worry about, it did what it did, now that you have it fixed, it won't get any worse, if you haven't noticed any loss in performance, it couldn't have done much
