What an air filter shouldn't look like.

Well the other day I decided to do a mini service on my bike.

I changed the oil and filter and plugs, and I noticed the plugs were fouled quite badly, so I decided to take a look at the air filter and it looked like this. Embarassed

I wondered why the bike spluttered on idling sometimes.

I spose I should check these things more often, and the filter looks as old as the bike. Laughing

I now have a new one in there thanks to David Silver Spares, and it only took one day to get from them! A big thumbs up to them.

Before it holed, the blocked air filter would have caused so much restriction that the rings, piston ring grooves and liner would have taken a hammering.
That engine was working as a Vacuum pump.

Then once holed, the unfiltered air could/would have carried dirt/dust etc into the engine which turns to hard carbon grinding polish when caught up in the combustion process.

I hope your engine hasn't sufered tooooo much.

Did you kick your own arse? Laughing

Pah, that's nothing.

Here is the one I took out of my (supposedly fully serviced 5,000 miles previously) GPZ500s a couple of months ago:

I wish I'd learnt this sort of stuff while I had my ped. I paid £50 just getting my air filter unblocked twice! Rolling Eyes

While we're on air filters I've been having real trouble getting hold of an air filter for my mito so been riding a week or so without one in there. Mad

The bike mechanic guy said it shouldn't do any harm in the short term (couple of weeks) is this right?

As long as you're not riding through some proper crap, so stuff is getting lodged up there, it shouldn't present a huge problem. But get it back on ASAP.

Wouldn't have thought so, it is unlikely that any bits of muck are going to get in through the airbox.

It might make the bike run a bit lean though. I would refrain from thrashing it if you don't have an air filter in place.
