variator mod by itself

[paulc227]

I ordered the stage 1 kit for my zuma and accidentally I got sent the wrong exhaust. What would happen if I install the athena variator with heavy rollers and ride it like that with the stock exhaust until the correct exhaust came?

it is just may be a bit better acceleration. Just use the stock torque spring and something like 6.5g roller.
