RPMs at specific speeds

The previous owner of a "new to me" 2006 swing installed Dr Pulleys sliders. At an indicated 60 mph, the bike is turning 4,500 rpms. At 70 mph, the bike is turning just over 5,000 rpm. How does this compare to those of you running OEM rollers? I only got 39 mpg in my first outing with the scooter. The scooter has 13,000 miles on it. Thanks for your feedback.

It would be courteous of you to go to the Introductions section and... Um, er, introduce yourself.

That said, 4500 @ 60 and 5000 @ 70 are pretty much spot-on for Dr Pulleys. OEM rollers will give you higher RPMs at the same MPH. Your 39 mpg is more reflective of stop n' go travel and/or aggressive acceleration.

Anytime you exceed 5000 RPMs the fuel consumption increases dramatically. The best fuel economy is below 4000 RPMs while the more efficient travel seems happen with a steady throttle hand between 4 & 5000 RPMs. YMMV

I have a 2006 and the previous owner installed "lighter weights" (his words, not mine) so she was faster from a stand still, my rpms are similar to yours and last weekend I put on about 550 miles, and half at around 80mph, gas mileage was about what youre getting. The earlier models, thats their achilles heal, faster speed drinks more than the later models.

I have a 2002 Swing with 15,700 miles on it. I am the third owner and only a thousand miles are mine. The 4500 rpms at 60 is about right for mine as is the 5000 rpms at 70, but my mileage is better. I get 45 to 47 mpg with mixed riding including some stop-and-go. The sliders in my CVT are OEM. Other than the grips, a Leroy Beals mod to the seat and a HID headlight, my Swing is pretty stock. Your mileage sounds out of whack unless you're a jackrabbit starts kind of rider!

I have 28g sliders and RPM's are similar to yours but fuel economy is WAY higher. I very seldom drop down out of the 50's and sometimes hit close to 60! At 13K you might need to check air filter and/or spark plugs etc. But as said above it could just be your riding habits... Good luck.

I think at 13,000 miles---return drive train to stock, new belt, at least check air filter and if gas mileage is your thing, mileage will get better as the machine was designed to do.

Sometimes "tackle box" tech mods screw machine up.
