Florida Jetting

[Hank]

I have a 2000 Banshee with Toomey T-6 pipes, K&N filter pods, Noss Cool head with 19cc domes, Chariot timing plate +4 and run VP C12 fuel. My jetting is 27.5 pilot with 300 mains AS 2 turns out. Runs great bottom to just over half throttle then it seems to flatten out. Compression is around 165 on both cylinders so does that sound like my top end may need to be redone? Temps are above 85 and my plug chop suggest I am slightly rich which is ok due to the deep sand I ride. Any suggestions?

read up on that site.

 

Remember when jetting.

 

Moving the mains around will mess with the needle setting as well.

 

I will always go up on jetting before I go down. If it gets worse then you know you need to go down. If it gets better then you know you need to work up. But if your saying its flat then im going to say your rich. If it Rev's with no power then your lean. Just set the main first then work on setting the needle height.
