i think i want to upgrade to a slightly smaller radix pulley. right now i have the stock 3.4...this is just for the time being, bc in about a month, the new heads and tune and even smaller pulley are going in. So i just want a little more power for the time being. what size do you guys suggest? also, the stock pulley is good for like 6.5lbs, right? so maybei could get up to like 8 lbs b4 the other mods go in?

 

Im currently running the 3.25" pulley and i see just over 8 psi. The 3.25 is a nice gain over the stock 3.4

 

I ran the 3.25" pulley for awhile, nice little gain over the 3.4" when I did my longtubes I dropped about a 1/2-3/4 PSI so I went to a 3.0" and it rocks.

sounds like the 3.25 is what im lookin for...for now. and the 8-9 lbs wont be harmful to the internals or anything? i plan on orderin this tomorrow....so should i just call Allen Nelson? i think i read he has a nice supply of these pulleys?
