JCSO605 Posted June 4, 2015 Author Report Posted June 4, 2015 I have but at this time no. Cause of third gear stumble???? Quote
JCSO605 Posted June 4, 2015 Author Report Posted June 4, 2015 I think I'm gonna drop the needle down a clip since its extremely rich and since the stumble is when I punch the throttle from second, Fuck it Quote
J-Madd Posted June 4, 2015 Report Posted June 4, 2015 I've had plugs look like that after a several good 300ft runs. I just assumed the plugs were gapped correctly on yours. That may be an issue Quote
dozer Posted June 4, 2015 Report Posted June 4, 2015 the carbs on mine are .122 main and dump egm needle .096 pj 60 pilot. Quote
JTmachining Posted June 4, 2015 Report Posted June 4, 2015 Box gap is wat I use to. Unless u have new plugs and make a full pass and then shut off...that's when a plug reading is done to tune. Pics don't show electrode ur prob not even close to lean Quote
BANSHEE HP Posted June 4, 2015 Report Posted June 4, 2015 I wasnt saying the not gapping the plug is your issue but its a question that no one asked yet and it does matter. IMO it needs more fuel, more than a couple times weve seen bikes chase all sorts of issues thinking its electrical or clogged or some how messed up carbs. swap their .120 dump tube carbs out to a set with .125 and the bike goes up and down the track. This would be on 465-535 and whatever a 14 mini twister is. Quote
JCSO605 Posted June 6, 2015 Author Report Posted June 6, 2015 Finally got her running like she should. 55 pilot air screws two turns out, .122 dumps .115 mains like loco suggested! Pjs about 3 turns in from wide open. Quote
