I dunno but I replace my Spork plugs every few months

[SimJen]

every 10-20,000km I spose. I'd be inclined to change them a bit more often on a revvy 250 four than say a 600 four.

[What?]

How long is a piece of string?
My F650 is fine with 10 - 20,000Km intervals, whereas the CB1100 will eat a set of NGK's every 5,000Km, and a set of Champions in under 2,000Km.
Then there is the old CR250, which will total any plug in under an hour.

Yeah thats wot i was told as a young fella.

I was googling a couple of years back and read about the vinegar method - i though what a load of bollocks.

My KDX ate a couple of plugs which were lurking on the workbench (as they do), and thought what the hell, so I grabbed some vinegar, poured some in a plastic jar and put one of the plugs in it overnight.

The vinegar eats away at the porcelin (sp?) and metal but cleans up the business end of the plug a treat. Gave it a burst with compressed air and wd40 and tried it, purrrrrfect. Still in the bike 2 years later, a bunch of rides and a couple of extra "vinegars" later.

Yeah but when the thing disintegrates from all the vineragereing it might not do nice things to the pistons and valves

"Interesting" didn't mean i was gonna try it myself.. even with iridium sparkplugs being $24, i only have one to replace (which i did a month ago).. I'm quite happy with the sandpaper and petrol thing anyway (been doing that as long as i've known what a sparkplug is)

So malt or white vinegar?


Ohh Ohh Ohh! What about Vinaigrette? Think we have some Lemon infused in the fridge.

[Ixion]

Balsamic, you heathen. Why on EARTH would anyone think to use anything other than balsamic vinegar to soak a spark plug in. Do you want to COMPLETELY destroy your engine?
