06BCBANSHEE Posted March 3, 2013 Report Share Posted March 3, 2013 hey guys did a plug chop today, almost killed myself 20 mins before, road was washed away, ridden this traill 100 times, if it wasnt for 2 dirtbikers waving me down I would have hit it 6 gear WOT one guy had o lay his bike down cause he couldn't stop in time. These guys def saved me some broken bones or worse. Def a eye opener, not to ghost ride trails. Im running: 280 mains 27.5 pilot air screw 2 turns out I already have a set off 30 and 32.5 pilot, prob gonna try the 30 for the main would I just need to purchase some 290-310 ?

lms1977 Posted March 3, 2013 Report Share Posted March 3, 2013 Why do you think your lean? It won't all have color on a plug chop it looks like you have color in it Quote Link to comment Share on other sites More sharing options...
gomerkfx700 Posted March 4, 2013 Report Share Posted March 4, 2013 i cant tell alot about it by the pics but looks like you have some color down in there may be the shadow looks like some color right around the electrode also like it either hadnt burnt all the idel time off the plug or something. but timing looks good looks like the ring is right around the bend of the strap but im not the best at reading plugs Quote Link to comment Share on other sites More sharing options...
06BCBANSHEE Posted March 4, 2013 Author Report Share Posted March 4, 2013 The second pic is more of a true representation of what they look like, ill cut the threds more in the morning, i thought it was supposed to be a nice tan brown. Well thats good anywaus thought my jetting was way off. Gonna throw the 30 pilots in, seems like its struggling a bit down low. Quote Link to comment Share on other sites More sharing options...
06BCBANSHEE Posted March 4, 2013 Author Report Share Posted March 4, 2013 Also i thought it was lean cause it doesnt amoke really once its warmed up. Does when its cold. Mixing 40:1 Quote Link to comment Share on other sites More sharing options...
Jereme6655 Posted March 4, 2013 Report Share Posted March 4, 2013 to accurately read a plug chop you need to cut off the threaded section of the plug while leaving the white porcelain....the brown color that should be on the plug should be at the bottom of that porcelain and be approximately 2mm tall. There's a sticky on the site about how to do a plug chop....it includes photos......read it.... Quote Link to comment Share on other sites More sharing options...
gomerkfx700 Posted March 4, 2013 Report Share Posted March 4, 2013 Your topend (high rpm) tuning is at the base if the porcelain about a mm or 2 thick band it should be tanish in color there is a nice read on hear somewere on plug chops and reading them Quote Link to comment Share on other sites More sharing options...

06BCBANSHEE Posted March 4, 2013 Author Report Share Posted March 4, 2013 hey guys, looks like im pretty close on my jetting; maybe a tad lean? my grinder blade was a little dull so it got kinda haggered cutting the threads lol. a bit of oil smeared on the porcelain. should I leave it as is?

LeroyJones Posted March 15, 2013 Report Share Posted March 15, 2013 I'm in the same boat with plugs and jetting. If it was me. I'd go up a size on the mains and do another chop. Or redo this chop and repost also show the ground electrode. The porcelain looks a bit lean. I hate not getting feedback when it comes to jetting.

volcrano Posted March 27, 2013 Report Share Posted March 27, 2013 Looks lean to me. Better pic of porcelain like looking down on it from up top. Make sure the motor is at operating temp then put in new plug. Do wfo and shut it off. Pull plug and ride back on others or shut off wfo where ur stopping to work. It looks like that plug had a lil ride time before the chop. The plug should only be used for the wfo at operating temp, thats it. Also, u better get a lottery ticket and a few beers for the dirtbikers. Quote Link to comment Share on other sites More sharing options...
06BCBANSHEE Posted March 27, 2013 Author Report Share Posted March 27, 2013 Hey thanks guys I was riding for about 30 mins before i did the chop. I stopped put new ones in went wfo and pulled my tethered kill switch. My hacksaw was dull as fuck, so it was a pain to cut these threads. I also may have let off the gas a tiny bit, ran out of room. I ordered some 290 and 300. This time im only gonna warm it up first and re do it. I think it should be prettu close at a 290. It runs awesome, and just a tad lean.
