Explorer misfire ...interesting conclusion
« on: April 26, 2014, 12:30:44 PM »
The recent misfire which had plagued my Explorer had an interesting conclusion which I thought I'd share. The bike was cutting out on descents and at traffic junctions etc. Nothing showed up on the diagnostics and then my local Ossa dealer noticed a frayed wire leading the the rear light. Presumably the wire had become frayed when the mudguard fell off . This was creating a short circuit when the brake was applied [such as when riding downhill of stopping at junctions :-[ ] Modern ignition systems with ECUs and such like don't like these kind of problems and this is why the bike was misbehaving. Full marks to the dealer for spotting it, I reckon I could have chased my tail for months with that one. Of course if the mudguard hadn't fallen off in the first place...

Good things to know.

Like my strange spark arrestor 'mud issue' if you have heard about it, that can be a first thing to check.

Hi Mark,
We don't have spark arrestors in the UK, in fact I've never seen one. I presume they are a safety feature if using the bike in areas prone to fire such as forests or grassland?

Yes, they are required for most of the riding areas ( even though it is quite wet here much of the time).

The one I have is an add on unit, slides right over the end of the muffler 'tailpipe'
It is a simple screen type.  The mud would build up and get baked on, mixing with carbon also I think.
The little mudflap solved it.
