trickedcarbine Posted December 7, 2015 Report Share Posted December 7, 2015 Looks like the plugs are not getting color as it's being washed away by excessive fuel. Typically a rich jetting condition or you're not getting enough spark. What is the total set up again? And what jets are in the carbs.

Buster91dg Posted December 7, 2015 Author Report Share Posted December 7, 2015 I thought it was lean and that's why it seemed sluggish Quote Link to comment Share on other sites More sharing options...

Buster91dg Posted December 7, 2015 Author Report Share Posted December 7, 2015 Coil and caps test good?Brand new ngk caps I didn't test the coil but it possible it could be bad bike sat in a bar for a year or two blown up. How does my plug color look? Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted December 7, 2015 Report Share Posted December 7, 2015 The plugs are soaked. That's why I asked if your electrical is good. Lean the needle and listen to everyone else. I have other people jet my bike for me Quote Link to comment Share on other sites More sharing options...
Buster91dg Posted December 7, 2015 Author Report Share Posted December 7, 2015 I'll have to try the needle it's already in the 4th clip down and these plugs look soaked to you I'm new at reading plugs imo I though maybe it needed a bigger main jet Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted December 7, 2015 Report Share Posted December 7, 2015 Take a photo directly above the plugs. It's hard to tell if it's wet plugs or light glare on that last pic. Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted December 7, 2015 Report Share Posted December 7, 2015 Maybe it's the pic, but is that oil sitting on the side of the plug? Sent from my SAMSUNG-SM-G890A using Tapatalk Quote Link to comment Share on other sites More sharing options...
Buster91dg Posted December 7, 2015 Author Report Share Posted December 7, 2015 Yes it is oil on the side of the plug and I thought the needle on did 1/4 -3/4 of the throttle Quote Link to comment Share on other sites More sharing options...
Buster91dg Posted December 7, 2015 Author Report Share Posted December 7, 2015 Everything works together throughout the circuit.... the needle actually effects pretty well the whole range and is crucial to have set up properly. a rich needle can cover up a lean main as well as a lean needle can cover up a rich main.... couple things that can throw off a small difference in smoke between the 2 pipes Bad flange o ring or not as good of a seal as the other side on the flange / cylinders pipe packing carb settings Idle adjustment A/F screws ect... the list goes on... Lean the needle by 1 clip and try again.. You can NOT read a plug by free reving the motor... the motor needs a load to get proper readings / plug color. forget holding wot runs for now.... get that bike going through the rpm range smoothly... so do a few 5-6 gear runs testing a few different things ( needle settings) and see if it was clean up that little "hesitation". once you got that cleaned up you can start doing some wot main runs. Those plug pics look ok ish for the most part... rich side for sure.... but doesnt mean squat. your low range can be reading spot on giving you a nice color while the needle could be rich and the main could be anywhere... The ring of the plug should have color all around it.... usually when its "clean" or partially "washed" it means its rich somewhere in the circuit. USUALLY. Ok thank you so that that would be moving the clip up which would lean it. And the needle is on the 4th clip down already so I'll have to put it on the 3 and then go from there Quote Link to comment Share on other sites More sharing options...
