National Banshee

Hi Guys looking for some quality Flat track parts. Let me know what you have. Thanks.

Hi, Im at 3000ft, We have one here with cylinder polishing only, stock airbox and filter. It runs 290 mains, stock pilots, needles in the middle position. This quad is pulling the CPIs and the Toomeys. Have fun..

What alltitude are you riding at? It is odd that it worked well before, your jetting should't have changed. We have set up new Banshees with FMF Fatty's,everything else stock, at 3000FT alltitude and had to go down to 230 to make it run right, BUT THAT IS AT 3000FT ALTITUDE ONLY.

Stock Banshee at sea level is 41.7 horse, With Pro Circuits, jetted properly they are 45.9 Horse.

Best all around pipe for what you are describing= Pro Circuit. Weve run Turners, FMF, Toomey and CPI. Each good in differnt areas, but the PC"s are without a doubt the best no compromise pipes.

If you are getting good steady spark, and fuel, you might want to check your compression. Good luck!

I agree, You really should run Premium fuel.

Have you tried putting your old domes back on. If it runs fine with your 19'S then perhaps you are detonating. You wouldn't think anything else would change with just a dome change.

Why are you running your jetting so tight? Watch your plugs, jet it accordingly. If you are lean, your going to have to richen your jetting. One size isn"t going to make that much diffence on a hot day, just richen up your mains. Stick with your original fuel mixture.

That sounds like older FMF pipes.

No need to rejet with the snorkel removed.

Agreed, Good call Boonman!!

Pull out the inlet needles and check for restriction behind the seats. You will have to unscrew the brass seats from the carb body. It's very common to have dirt or fuzz get trapped behind the seats. This will cause a restriction in fuel flow, and it will run out of gas. If you let it idle, it will take off again for a minute and then do the same thing. In other cases the dirt will hold the needle open causing it to flood just as you described.

I just recieved my replacement set of AC Pro pegs. These new ones are excellant fit, and the welds are very nice. These have the rear guards as well. I belive it is important that your nerf bars provide as much protection as possible, to keep someone else's wheels from getting into yours. Some nerfs are to far in at the front. A good nerf will have a slight angle out, not be below the center of your wheels, and come as far ahead and back to keep a tire from getting in contact with the face of your tire. I have seen some that leave as much as 12 inches open in front of the rear wheel. That's just to much! The AC's are good, the Graydons are good, and even the DG's are a good set.

Once again it is important to know your elevation. 19cc domes at sea level would be a bit small in my opinion without 100% race gas. I am not a big fan of pushing the head volume that closley. If you burnt a hole in the top of the last piston, you were more than likely detonating, so I agree with whoever told you it was your fuel. Most people make the mistake of running to small a squish area and end up jetting it so rich to keep from blowing it up that there mods are worthless. If your altitude is less than 1500 ft, I would go to a 20cc dome set, then work safley on your jetting, but that is only my opinion. I assume your ignition timing is still stock?
