About to change spark plugs - alternatives and reasons?

[McJim]

I'm about to change the spark plugs on my wee 600ss. The reccommended plugs are Champion RA4HC.

Now I hear lots of stuff about different plugs providing better performance and other plugs that burn holes in the top of your pistons etc.

I was wondering what are my options? Should I go with the stock standard ones as reccommended or are there fancy ones I should put in ther to squeeze a little more performance out of the wee lump of metal?

I don't think you'll get any noticeable increase in horsepower from using fancy plugs, unless it's missing like a bitch, and if brand-new recommended plugs are doing that then it's not the plugs you should be worried about.

Just chuck in the recommended ones, or NGK equivalent.

If with the brand-new plugs, you pull 'em out after a few hundred kms and they look a little hot or fouled, you could move up or down a heat range in the same plug. I moved to a DR9ES from a DR8ES-L -- the 9 is one step cooler than the 8, and the `L' suffix means it's suitable for sub-5-degree conditions (don't need that). One step cooler meant less chance of the occasional hot detonation I was getting after the motor was really cooked.

Go with the recommended plugs. If you're ultra keen you could pull your current ones out and have a look at them first, but unless you've already got problems I wouldn't worry.

Unless that 600SS has mysteriously turned into a two stroke.

Yeah, I've got a 2 stroke conversion kit on order to get more power...it arrives on 1st April.:rofl:

Thanks. Bike has no problems - I'm just changing oil, filters and checking the tappets this time - basically doing everything I can to make sure the bike doesn't have problems in the future (she's done 50,000km so far)

Damn you! You tricked me once with that long ago :laugh:

Ducatis don't have problems, do they?

Hmmm, yes well I'll have none of your cheek about Ducatis until you can prove to me that you too can reach C 2 octaves above top C on a trumpet:rofl:

Gonna whip out the plugs and have a look before I buy as the bike is running sweet anyway.
