Nice looking GEM, you have really shined it up , it looks brand new. They are great for running errands and cheap to operate. Don’t forget to get insurance because they are considered cars when on the street. Have fun ---

Hello kinghappy Good idea, but after a lot of reading I don’t know if it will help. Am I correct? 03/26/2014 mfg date 185/60 R14 tires @ 914 revolutions per mile 7 HP motor @ 4100 rpm 10.35 to 1 axel 120 miles on e2 with 20 miles on new gem gels (((4100\*60) / 10.35) / 914) = 26.00 mph max Need more rpm Need good lithium battery setup Would like to get 40 mph for short traffic runs. What do you all think? Peter ---

The MM from Dave will allow your GEM to go beyond the factory limit set at 26mph. I installed one and it works great. Actually had mine up to 45mph on a downhill street lately. Alan ---

i assume the black 7hp advanced motor ? Had one of those in my 2014 cart , added lithium and reprogrammed to 37 mph, a few months later motor violently self destructed , locked up the front wheels while i was driving . Fortunately didn’t get hurt and didn’t damage the trans . dont know for sure what caused it but it was unfixable and scary . ---

@LithiumGods A car guy all my life, I will not run “red line”. Lost a rod racing a friend’s GTO when I was a kid. The OEM 7HP is rated 4100 rpm max “red line”. Will need to convert to a 6000 rpm motor. Thanks for confirming limitations of OEM. ---

That sounds horrific and scary. This is good info for people to know. ---

@Old_Houseboater for this. Can’t upload it here. As you can see oem exceeds the listed rpm . That number is not a red line . Most likely relates to efficiency and continuous operation at rated hp. My Tomberlin has a 3500 GE motor and runs close to 5000 stock. Small tires and \>12/1 gears. Bursts of 6,000 should be ok IMO. I keep under 5800 myself. @LithiumGods was pushing 7,000 rpm I bet. Maybe he can report tire dia. and gearing. ![image](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/e/eae4420eb9190eda386b16cc81f5c553c6e5f482.png) ---

@Inwo Thanks for the info. I agree with you, 4100 is not red line. Engineers would have built in a margin for longevity and safety. The only question is, what is the true top rpm?
