Post does my max rpm sound right???
Hey all,

I have a 2005 Zuma.

I have the following performance mods:
Daytona Style Super Power Air Filter
jet kit. i believe running 82
Giannelli V2 exhaust
NCY transmission kit.
yellow clutch spring
yellow torque spring
7 gram Dr. Pulley sliders
NCY variator
Final drive Helical cut 15:50
tachometer
dual headlight mod

all that being said my top speed is 48mph at about 8700 rpm.
if i use 5 gram rollers instead of my sliders i get 42mph at 8900 rpm.

I really am not sure what my ideal rpm power range should be.

Stock carb
Is the filter a stock replacement type filter or a it a worthless pod filter can’t tune a stock carb to an open filter besides the oem air box is good for the 90 cc engine and these engines like running an air box
Jet kit what size and is it the right brand if your running a tk and it’s not a tk that can be an issue
Almost every one with a pipe on a stock bore doesn’t have to change a jet just adjust the needle

Sounds right that your speed dropped with the lighter rollers the stock bore doesn’t have the right power band to pull gears

i guess i should say. it runs great the stock electric choke is kinda annoying how slow it goes. like 1500 rpm higher on startup than 10 min after. so idles cold start at 3k rpm.
