Still no gogo...

Hi All,

The storey so far... The bike stopped working after a weekend of heavy rain. I've drained the carbs etc.

Pulled the plugs - the front is wet with petrol, the rear dry. I know feul is getting through so I assume the rear cylinder is firing, whilst the front isn't. Swapped the plugs and got the same thing. Checked the HT leads. The plug cap was loose on the front, so I trimed it a bit and screwed it back in again - it's now tight.

The people in the shop said to hold the plug against the engine - but I've been told by others that as the SV is likely to be a MOSFET ECU this could be a very bad idea - killing the ECU bad. Comments please? Does anyone know how I can check if there is a spark without putting the plug against the engine. The only thing I can think of is getting a colourtune - but is that going to fit into the tight space available on the front cylinder?

Other than that anyone got any idea what else I can check before giving up and taking it to the shop for lots of cash :(

TIA

Stu

You could check if the things are firing by using a Timing light

I beleave that the Haynes manual says that if you want to test the spark plugs, then you should ground the plug casing to the engine. Becarefull that fuel does not come out of the plug hole and get ignited by the plug.

If you have a Haynes manual, look at the back for trubbleshooting an engine.

Not completly sure on this though, but the haynes manual has it discribed properly.

Thanks both. I'll have to see if I can pick up a cheap timing light when next in the UK (not paying Dutch prices) and if not just have to risk the plugs against the engine I suppose...

I'll let you know how I get on...
