Zen G320 top speed

[rcr1978]

Hey guys I'm new here just got a new 5iveT roller about a month ago, just got it broke in and running around the last week and have about 3-4 tanks through it. My motor is a stock Zen G320 with a Bartolone 32cc pipe and my top speed is only 31mph with the stock gearing which seems a little slow to me what's everyone else seeing with this or similar setups?

On a 320 with stock gearing you wil not get much top speed. This engine is more of a torque monster. You will have to change your gearing to gain speed.

Because I race, where torque is essential so I have stock gearing.

Agreed, mine is slow too. The truck needs the low end torque and in order to have good top end, I am looking into a 2 speed.

Cool thanks guys just making sure mines not a turd, guess I will try a few pinions until it loses bottom end.
