2005 gear ratio change

I believe the 2005 GEM comes with 10 to 1 gear ratio. Im running bigger tires and think I should change to 12 to 1 because of the hills and being an E4 full of people seems sluggish.

Will going to 12 to 1 help?
Thanks

Actually its 10.35 vs 12.44 Yes it will help. If speed isn’t important 14.76 is available

Do you know where I can get a set of 12.44? Also if my GEM is going 40 MPH now what would I expect with 12.44? 30-35?

Thanks

Marlon has gears.

Eventually you can expect to trash the motor from over revving.
