tombo46 Posted October 7, 2008 Report Share Posted October 7, 2008 How often do you change your spark plug? how long are you meant to leave it before replacing it? All the best Tom Quote Link to comment Share on other sites More sharing options...

hoggle Posted October 7, 2008 Report Share Posted October 7, 2008 I carry a spare too, and was told to change it if you think the one that's on the bike is Goosed ! So i will leave alone till i reckon it's knackered ! Quote Link to comment Share on other sites More sharing options...
bikespace Posted October 7, 2008 Report Share Posted October 7, 2008 It costs about the same as a tank of fuel, so although I don't change as often as Dabster, I would say every 3 or 4 months I put a new one in and throw the other away. Saves the hassle of a dead plug. Quote Link to comment Share on other sites More sharing options...
zippy Posted October 7, 2008 Report Share Posted October 7, 2008 About once a year maybe twice. It can make a difference in performance seems to perk the old beast up a little. Quote Link to comment Share on other sites More sharing options...
copemech Posted October 8, 2008 Report Share Posted October 8, 2008 Those darned Monty plugs are expensive too! It is sort of a funny chain ov events, yet as I recall, the VX plug that was only used for a few trials came out of my '05 bike when I sold the bike and went into my '07 bike when I got it in about December '06 and is still in the bike. All plugs in a 2T seem to require a bit of special treatment to prevent them from fouling with gas and oil, but the VX platinum is more resistant to fouling than a standard plug, and if you keep it clean it will last with no problem. You need some heat in the motor and do some hard runs and occasionally rev the pee out of it to keep it clean, same for exhaust. I run them at .027-.028 reliably! I have a spare used VX that was in my '03 bike when I sold it in '05. Just an old beater for a pinch! I still have 2 new spares somewhere in my kit box I think.

toothandnail Posted October 8, 2008 Report Share Posted October 8, 2008 I have a spare some where, I can only remember fouling maybe 4 plugs in the last 10+ years, two of those were the new split fire, which fouled within 5 minutes in my Banshee. I can't say I don't change one on occasion 2-3 yrs maybe, always wonder why after Quote Link to comment Share on other sites More sharing options...
