Fastassbanshee96 Posted April 16, 2010 Report Share Posted April 16, 2010 I broke a sparkplug off in my coolhead. All the threads are still in the dome. I figured the best way to get it out would be take the head off and try to screw it all the way thru. Does anyone know of a better way of doing this without screwing up my dome or head. Any info would be great. Quote Link to comment Share on other sites More sharing options...
Fastassbanshee96 Posted April 16, 2010 Author Report Share Posted April 16, 2010 Thanks. That's what figured I would have to do. Befor it happened my left cylinder wasn't firing... If the plug was broke when I was trying to start it, would that sparkplug still fire or not. Quote Link to comment Share on other sites More sharing options...
AKheathen Posted April 16, 2010 Report Share Posted April 16, 2010 did you use champion or autolite or something? Quote Link to comment Share on other sites More sharing options...
Fastassbanshee96 Posted April 16, 2010 Author Report Share Posted April 16, 2010 I think they were nkg or something like that. I got the rest of the plug out and tried to put a new one in but the top threads were wasted on the dome. I took it to Yamaha to talk to there techs and they said I couldn't fix it cause every time they started the tap it would go side ways. I don't thing they knew what they were doing.... I ended up getting a plug chaser with alittle bet steeper pitch on the thread and ran it in thru the bottum of the dome and got plugs to match. Now it runs like a rapped ape.

AKheathen Posted April 17, 2010 Report Share Posted April 17, 2010 well, yah, if the top threads are messed, then you start by chasing it through the bottom, lol. they should have known that. if there is not enough meat, then tyou can buy a sparkplug thread repair kit made just for that. i had to do it on an s-10 2200 that i bought where someone tried to remove hot plugs and galled the threads.

Fastassbanshee96 Posted April 17, 2010 Author Report Share Posted April 17, 2010 Yeah I don't think they were too bright. Lol. I think the guys at the store who sold me the tool said that it had a steeper pitch on the thread. The new plugs seem to be holding great.

jbooker82 Posted April 17, 2010 Report Share Posted April 17, 2010 Or a new set of cool head domes are like 60 buck. Probably the cheapest way to go if you have to buy the tools to fix it. On a side note dont use an 1" drive impact to put the plugs in. Quote Link to comment Share on other sites More sharing options...

The tool was only like 7 bucks so I would say it's definetly the cheaper rought. And of corse I'm not using an impact. I actually spun it in by hand but for some reason when I was pulling it out (cause the left side wasn't firing) as soon as I put the wrench on it, it just snaped the threads off in the dome. But it's all good now. Quote Link to comment Share on other sites More sharing options...

I usually use a torque wrench and a 4ft section of pipe to really get them tight LOL Quote Link to comment Share on other sites More sharing options...

dmfisher71 Posted April 17, 2010 Report Share Posted April 17, 2010 I usually use a torque wrench and a 4ft section of pipe to really get them tight LOL thats a little overkill, you will eventually pull the threads out if you do that, they just need a tightening with a 3/8" ratchet snug it up and just a little more..

AKheathen Posted April 18, 2010 Report Share Posted April 18, 2010 you know, i always see a bunch of "i like to....." and never just do it by following std. plug install directions.....get used to doing that, and then you just do it by feel with a combo wrench.....
