2020 ruckus that I purchased new in July and it now has 1100 miles and has ran fine.
Current mods are, Ncy Cdi, Ncy coil, ngk 10 iridium plug, polini variator and a constant mix of 4.5, 5 and 5.5g dr.pulley sliders, yoshimura exhaust, TRS TVR intake, 38/78 jets that were included with the intake, I have not yet installed the needle shim that came with the intake kit as I had read a considerable amount of info saying it’s for covering up bad jetting.
Before the intake and exhaust I had a mix of 4m5 and 5g sliders and would turn 49mph at 10400 downhill. Flat ground was 40-42 depending on the weather and if it was actually flat.
After intake and exhaust and jets it felt better and would easily do 42-44 on flats and still rev out to 10400 at 49.
Tonight I swapped to 5.5g sliders and I feel like it’s a mega turd. I ran the velocity stack in and out about 1/4” each way and made passes and it felt better just a hair out from the 1.5" that it came to me at.
I’m at 700-900ft elevation, DA is usually in the 2500-3500 range. I’m not tucking during these tests to keep things the same. Stock tires and pressure is at 30 front and rear.
I currently need to redo the tach lead as it freaks out and shows about half the revs once it breaks 6400 under load but it’s audibly lower in the revs and not trying to pull thru them as I expected it to after intake exhaust and rejet.
Do I have a hodgepodge combo that just doesn’t work? How would you proceed?!
