Idiot alert

[freeridenick]

I've managed to loose a small o-ring inside the front cyclinder. I'm hoping to get it out but I don't have a borescope, so I'm stuck with a thin bit of wire and a stunning sense of feel.

Question: if I can't get it out is it just dumb, or is it extraordinarily stupid to try and start the bike regardless. I suspect I know the answer.

Personally I wouldn't bother. Not much chance of fishing it out. It'll burn up or blow it out of the exhaust, at worst trap on the exhaust valve seat but would also quickly burn up. Best of luck fishing.

Try taping a piece of airline (small enough to go through the spark plug hole) to the end of a vacuum cleaner nozzle and fish around with that inside the cylinder.

Is it a rubber o-ring

[VTRDark]

That was my first thought If it's rubber then leave it. If it's metal then get it out. If your fishing for it I guess it's rubber because if it was metal you would have it out by now with a magnet.

Take the sump off?

Not sure I'd want an o-ring floating about in my engine...

Aye, take the wheels out also and get rid of them there big o rings.

Is it a rubber o-ring

Yes. It's an o-ring off the thread of a compression tester. It was something like 6 or 8mm in diameter.

My worry is that it'll stick to the cylinder as it burns up. Although, it is pretty hot in there.

[Jamoi]

It's in the actual cylinder? Bugger

Although, it is pretty hot in there.

To say the least. It will be about 2000°C in the combustion chamber. The rubber wont just melt...it will be obliterated.

I had to click on this thread just to make sure he wasn't talking about me.......
I hope it sorts itself out dude......

[mattycoops43]

I would just run it and not give it a second thought.

[freeridenick]

OK then. Ten minutes of 'fishing' in the morning. If I'm lucky, great, if not then I'll fire her up.

Fingers crossed. Thanks everyone.

hit button.
o-ring gone.

Wish it was that simple. Got a tank to finish connecting, oil cooler to attach, fluids to go in and an exhaust stud to fit first.

Best bet seems to ignore my head and follow my heart, which says it'll only take an hour.
