One-mile long easy uphill, with a couple short flat spots in the middle.
Last week, with stock flywheel, could not GET above 30 mph (speedo) the entire distance.
Today, with lightened flywheel, tried it again and was not below 33 at any point, and at best up to 36 mph, SO THE LIGHTENED FLYWHEEL DEFINITELY MAKES A DIFFERENCE! (Speedo mph used only for comparison, not to establish ACTUAL speed.)
I re-read the thread about lightened flywheels
because I was wondering about the differing reports on whether this mod makes a difference. I noted that when JCRacing began lightening them, John was taking off about 4 ounces. Mine is slightly more than 6 ounces lighter than stock, so perhaps some differing reports have been in part due to that change.
In addition, I think it would make a more immediately noticeable difference if your scoot is not optimally tuned. If the scoot is well-tuned or at least close to optimal, installing a lightened flywheel may not make as dramatic a change. As noted in my experience above, I needed specific measured parameters to be sure that there was indeed a difference. Riding on flat roads, it feels like it accelerates faster, but I had no real benchmark.
Now I will do more riding and see if I can determine whether I need to lighten my sliders to raise my rpms (not hitting 8000 until 40 mph
) or if that is simply due to sudden decrease in temperature. I'm wondering whether varying reports of needing or not needing to change weights are also due to differential stages of CVT tuning at install.
(ps--get yours done! Good Vendor bump!)
