Belt question

[honda hunter]

Im stockpiling pulleys in order to reach my goal. I now have a 10# lower sitting around and a 2.7 upper. I'm @ 16# with my 5# lower, stock upper, and ported blower. Anyways, my question is (I searched and looked at the belt how to thread) What belt do I use with the 2.7 upper and 5# lower?

the info i have is.

5lb lower/3.5" upper/stock idlers-68.5"
5lb lower/2.76" billet flow upper,metco idler 90mm,and tab removed.67.5" belt

so maybe a 68"...?

Thats where Im lost. I have the stock idlers so im guessing 68 just not sure.

I was just re-thinking about this. An Idler usually requires a longer belt..so a 67 to 67.5 should work.

Im sure someone else will chime in.
