Banshee Is Bogging On Take Off

[Infamous039]

My banshee is seeming to still have a small problem. It starts fine and idles great. When I pop it into first gear and give it a little gas it will bog down, I have to rev it up some to get it going. I also notice that alot of blue smoke is coming out of my pipes and is not like normal even after it has warmed up. I have cleaned my carbs numerous times, sync them, refreshed my gas and oil, new plugs,cleaned air filter, checked reeds and still no change. It have checked for spark and both cylinders are gettin great spark and are firing good, the problems is only on taking off. When I am riding it I have to keep it revved when taking off or it will bog down and shut off, but once I am going and start ripping it through all the gears it runs fast. It is basically a low end BOG, Could it be that I am lean. Please give me some help on correcting this problem????????????

Sounds like your slides are backwards or your jets are clogged.

My cut aways a facing the air filter, so I know that the slides are in correct, i went made sure of that.

Bring the bike out on sunday, We will get it up and running..Also, Most people I know that run FMF normally use a 27.5 pilot.. FMF seem to like a fat pilot. 310 on the mains sounds a little rich. Im at 300 right now with no airbox, toomey 2-1 filter, rockets and a port job and its dead on. My plugs look great!

Thanks Ellison I will bring the bike out, and will also change the pilot to a 27.5 and see how the shee likes it. I thought the bike was running lean. My plugs have a chocolate coating on them.

The chocolate ring is for the top end, You problem sounds more like the pilot or needles.

Should I purchase new needles?? I am going to get a 27.5 pilot and see how the bike runs with that.

[ellison445]

no, just need to adjust what you have.

drop in the 300 with 1.5 turns on the air screw. Chase is right, Follow his instructions and let me know how it runs.

[Infamous039]

Ok I will give that a try 2morrow and let you know how it runs

[ellison445]

Remeber, One change at a time. Change the mains first than run her...
