Title: Sparkplug question Post by srinath on 06/11/20 at 05:50:56 I was a mechanic on a bike years ago and I was having a lot of trouble getting it to start easy on the stock spark plug. I had to use a lower heat range plug. It was jetted perfectly fine BTW. Now My son's bike has one of those new fangled across the thing electrode etc - something VIX is the model of the plug - and since he's riding it in my yard and barely gets it warm enough - I think its fouling out rather easily and often. Does that type of plug - I need to get its make/model number to post as well - but does it foul out easier ? And a lower heat range plug is a better option here ? Or any other ideas. Cool. Srinath. |

Title: Re: Sparkplug question Post by Gary_in_NJ on 06/11/20 at 06:34:11 Some more info would be helpful. What kind of bike is it? What is the condition of the air filter? Are there any mods to the bike. What does riding in the back yard mean. Are we talking about a space that is 50’ x 100’, or 15 acres? What is your son’s riding experience and style? |

Title: Re: Sparkplug question Post by srinath on 06/11/20 at 06:42:28 Savage 98 model, kiddo has no experience except on a bicycle, its a 50' diameter circle around 3 trees. Basically the motor is on the verge of stalling all along and last time it ran, he forgot to take the choke off. In fact most of the time it is cold when he starts it, tepid when he rides it and barely warm when he gives up. All stock bike with clean filter and no mods - not even pipe or lighteing or my favorite - drag bars. Yea I really need to get it on the road and let it burn off those nasty carbon on everything. I'll do it Saturday I'm thinking. But on a longer term, I think I'll get a few of those colder plugs (the ones that burn off carbon sooner) on hand. Its likely I am gonna take one plug out and swap other one in and it would be better to clean and dry the spare and hold it for a swap. Cool. Srinath. |

Title: Re: Sparkplug question Post by Gary_in_NJ on 06/11/20 at 09:34:35 The Savage uses an NGK DPR8EA-9 standard spark plug. Nothing fancy about it. |

Title: Re: Sparkplug question Post by srinath on 06/11/20 at 11:27:00 I think the one I swapped in a few yrs ago was a DPR7EA-9 - let me check into that series. This bike has that VIX one - not any plug I have seen, that NGK is common on jap bikes, have had many with that same plug including my GS500's all 17 of em. Cool. Srinath. |

Title: Re: Sparkplug question Post by Gary_in_NJ on 06/11/20 at 11:30:57 The NGK plugs with an IX prefix are Iridium spark plugs. These are not required for our low output ignition and carburetor fuel delivery systems. You're never going to get a sparkplug last 100,000 miles on a Savage. |

Title: Re: Sparkplug question Post by DragBikeMike on 06/11/20 at 11:45:38 Once you foul a plug ridding around with the enricher on, it's pretty hard to burn it clean by riding around in a 50 foot circle. Just change the plug. The DPR-7EA is one heat range hotter than the DPR-8EA. The 7EA would be a better choice for cruising in the yard. Once it goes back on the street probably best to install the 8EA. |

Title: Re: Sparkplug question Post by srinath on 06/11/20 at 16:38:44 That 7 ea was what I used a few yrs ago, that bike was not a yard ridden bike - even on the street it was hard to start with the 8. I took out the plug and cleaned it - and it fouled again without even starting. But Let me get 7ea plug and keep the vix as a standby. Cool. Srinath. |

Title: Re: Sparkplug question Post by Ruttly on 06/11/20 at 16:51:26 From my dirt bike days we would always pack a bic lighter in tool kit & when the plug fouled we would dip it in the fuel , light it and burn the fuel off and put it back in. I only run NGK or Denso plugs. Them fancy plugs are usually made to cover several heat ranges and I don’t use them. If your fouling plugs either your engine is worn out or you have carb issues. Don’t blame the spark plug. |

Title: Re: Sparkplug question Post by srinath on 06/11/20 at 16:54:04 The bike got run for its previous time with choke on and it was run 3-5 mins at the verge of stalling. Never got hot enough to touch - cos its not been on the "road" in months. Cool. Srinath. |

Title: Re: Sparkplug question Post by srinath on 06/13/20 at 05:18:36 Sorry the plug is an E3.36 and I pulled it out and it was gas fouled. I cleaned it and it has no spark testing it outside. I have to figure out why - and likely replace the plugs with the 7's. BTW I did the spark plug door mod, in fact I removed the thing completely. The plug is still very hard to get to and remove. Does anyone have a wrench/trick combo to get it out easier. Cool. Srinath. |

Title: Re: Sparkplug question Post by justin_o_guy2 on 06/13/20 at 10:36:46 If you dont have the tool kit plug socket, its a booger.. You can get a lawnmower plug socket for next to nothing at Lowes.. And once its loose, a plug wire boot shoved on it will let ya spin it on out, and get a new one started. |

Title: Re: Sparkplug question Post by justin_o_guy2 on 06/13/20 at 13:32:57 Correction,, HOme Depot,, They have a deep socket that has flats for a wrench,, Its a cheap, stamped steel thing,, They had boxes on a shelf in the lawnmower/weedeater department. |

Title: Re: Sparkplug question Post by Gary_in_NJ on 06/13/20 at 16:36:04 I’ve never needed a special socket for the Savage. Just a regular spark plug socket with the cushioned insert. As for extensions, I find the 3” extensions with a u-joint between them allows me access without removing the tank. |

Title: Re: Sparkplug question Post by srinath on 06/13/20 at 16:57:55 OK I think what I am missing is the tilting/swivel head ratchet of 19mm - Its here somewhere - OK let me find/buy it. Along with the sparkies. Cool. Srinath. |
|
Title: Re: Sparkplug question Post by Gary_in_NJ on 06/13/20 at 18:14:28 Thinking about it...I may just insert the u-joint directly into the spark plug socket. |

Yea this worked. I will get myself a 7 and maybe even a 6 or the autolite equivalent soon enough. Cool. Srinath. |

Title: Re: Sparkplug question Post by srinath on 06/20/20 at 08:35:49 Got it started with the champion ra6hc - and really looks like it needs a valve adjustment. Will do that shortly and post back. Cool. Srinath. |
