How often change your sparkies?

[dadofthree]

once a year sounds resonable to me. Prolly in the spring when your doing all your regular "out of winter storage" ritual if your one of those people that dont ride in the winter.

I can see why most don't do their plugs till a certain point. They have to pay someone to do it. If that was the case with me, I would rack up the mileage before I changed them. But after 8 months or so you can feel a difference in drivability with a fresh set of plugs. It's not a huge improvement....but I notice the difference and that's all that matters to me.

I change mine and a set of plugs hasn't been that expensive for me, but I just hate changing them to change them. On the '06 I was doing it every 12K, but after talking to a few members decided to let it go a little longer on the '08.

I have just ove 10k on my gen II and plan on changing them in the spring. I think thats a good area of mileage for plugs. I have inspected them around 7k and they looked great still.

Perhaps if I was Chugging back and forth to work in stop and go traffic day after day would consider the yearly thing.......

Not the type of rides i get on her.

The old 2stroke dirt bikes we hung a spark plug wrench off the front of it and 2 spare plugs in our pocket....

which clutch release are you using?? i see mps makes one but had doubt on just how adjustable it was. stock clutch?

mps yes stock clutch after i pull in clutch i put thumb on the big button that holds clutch in clutch release is trapping fluid.Then i let off button on top yellow on a bracket race or full tree.Delay box kicks in releases clutch after delay timer runs out.Im sitting there with launch box cutting motoe @ 7,800 rpm.
This setup got me points championship this year so im racing free next season (gold card.Thats my 2nd in last 3 years.

Im running a launch box or rpm limiter when it kicks in its partialy killing spark.
I thought that may have hurt plugs a little.Gotta admit they did look ok
but I thought bike sounded little better.

If you wnay to throw your money away, do them as stated above, but do you change your plugs in a car that often, no!

Years back with the higher ingnition systems, yes they need to changed more often, but not with fuel injection!

C'mon John, u know better. U can't comp a car to a bike in this matter cuz our bikes spin well over 10g on a regular basis, whereas 90% of automotive engines are lucky to see 5200, unless ur driving a rotary engine car which will turn 9800. And all tho our bikes are fuel injected, they still don't have fuel control, not all anyway, like an auto app. ie., H02 sensors (both up and downstream), M.A.F., ECT (electronic coolant temperature SENSOR; not to be confused with CTS (coolant temp sending unit), etc. You get the point. Grant it, with Iridium's and todays technology, plugs can go longer, but that also will very with riding style, habit, and use. Moreso if your using a launch limiter, turbo's, NOS, etc, etc......
