SpecOps,
I think the PO may be a bit confused, so take what he said with a grain of salt.
There is No Stage 4 kit for our bike.
DynoJet only makes a Stage 1 and Stage 7 kits for a Vmax. http://www.dynojet.com/jetkits/motorcycle/yamaha.aspx
They don't make a Stage 4 kit for any bike that I can find.
And Factory Pro offers Standard or Titanium kits

I need to get back and make a dyno run on Skullduggery with the air box lid off. I'm running way rich here and by looking at the plugs. 147.5 Jets,
30 thousandths shims. Basically stock carbs air box and a Kerker with a 12" marks can. Some motor work. Wonder if I can get 2 HP or maybe a little more? The bike may even run stronger?:ummm:
