Crash summary - advice needed

[dyzio]

Ok, it went...

Good news:
- It's alive!
I expected to have to keep it on the starter for a while, but up fired up pretty quickly. Yes, yesterday it looked like a flat battery, but it never had any problems (even after starting after sitting in the lock up for 2 weeks last winter) and didn't understand it.

Bad news, unfortunately:
- started on 1 cylinder (rear), front didn't kick in, I've taken the spark plug out, it was covered in oil. Cleaned, refitted - same thing.
- Huge puff's of smoke from the exhaust at the first start. Didn't smoke so much after I've cleaned the 1st plug.
- this one's scary - there's oil in the exhaust .




Picture is rubbish (mobile), there's a bit of it "on" the baffle, also when I've started working on the 1st spark plug, the oil started flowing out of the can and slowly flowing on the bottom of the link pipe.

Can't really tell (yet) if it's the old oil, or if it's using the topped up one.

What's happened is the bike being on its side has leaked oil into the airbox, from there into the inlets and cylinders.

It's a bit of a git. The way I've done it in the past is to crank it with the plug out (coil connections removed), then to just keep trying to fire it up, you can warm plugs up to vaporise oil fouling or just wipe them off. After a while the fuel vapor will thin the oil enough to spit it out of the exhaust. Clouds of smoke are fairly normal.

[dyzio]

So you're saying, it's more or less normal?

Ok, I'll be needing step by step instructions here:
- I should take the 1st plug out, fire it up (don't know why but the idea of starting the bike with 1 plug missing sounds scary to me).
- clean 1st plug/refit - fire up?

One other thing, how can I check if the plug actually sparks? Put it against the frame, and press the starter, right?

[yorkie_chris]

Yeah that's pretty much how you check for spark. You don't want to start it with one plug out, just crank it, it should spit the excess oil out at least enough for it to fire up, as soon as it fires on that pot it'll burn the oil off.

[dyzio]

In short,
1)check if plug sparks
2)take cap of 2nd plug and "start" it (with the 1st plug out).
3)fit 1st plug and both caps and start.

[yorkie_chris]

No don't crank a motor without plug caps on, either earth the plugs somewhere away from the plughole or disconnect the coils.

You don't want high voltage jolt from the coils with nowhere to go as it can do damage on some systems.

[dyzio]

Sorry for so many noob questions, but I my spannering skills are (were) limited to changing oil and plugs.

Got a Hayens, so I think I know what you mean by "disconnecting the coils" (the two thinner wires going into the coil - hayens picture).

ok, off to the lock up in 10 min, suddenly a internet connection in your garage doesn't sound silly

In my crash (double back flip and a 180 to finish) all the oil in the engine completely leaked, I can't where it leaked from it seems to be out of the mid section of the bike (airbox was very oily). Is it possibly for a lot of oil to leak this way or is my engine bust?
Soz to hijack but i'm worried!

[yorkie_chris]

Yes you can lose almost all the oil out of the engine breather into the airbox if the bike is laid on its LHS. However do check for cracks to the sidecasings.

Cheers chris!
Yes it did land on the lhs (eventually), that's took a load of my mind - hope it's right.
thanks a lot chris
