What is the Most Economical RPM to Ride at? By carefulrider (Read 358 times)

I have a 2008, Sunl, Adventure, LB150T-12; 157QMJ, with a 150 cc GY6 engine. The scoot is equipped with all stock parts. No modifications of any kind. I just attached a tachometer to the scoot, as this model didn't come with one.

Now I wonder what the most economical RPM is to operate the scoot.

Its a balancing act. While 7000-7500 is optimum for accelerating it some times means higher rpms on the top end cruising MPH. The downside to low rpm acceleration is overworking the motor. Id say around 6000-6500.

Please, give us the low down on the tachometer you installed and how you did it.  I have been wanting to do this with my scoot but don't know how.

5 minute one wire install. Wraps around the plug wire.

Thanks for the suggested economical rpms.

As TwoWheeler said: simple to install & easy enough to wrap around the spark plug cable.

I bought the one I use on eBay. I expect that if you did an internet search, you shall find several sources.

I put it to use to adjust the idle rpm down to the suggested 1300-1500 rpm.
