Hey everyone. I recently joined the ruckus community when I bought a 2012 ruckus with 7.4k miles for $900. I’ve since discovered the previous owner put on an ncy cdi, polini variator, and 5.5g dr pulley sliders, so it seems like a pretty good deal.
However, my speed on this thing feels a little lower compared to other people and I’m not sure if I just have false expectations or if something needs to be tuned. In addition to the previous owners mods, i’ve done an airbox delete and put on the psp carbon tip exhaust(it seems like it performs similarly to yoshimura at a fraction of the price, as far as I can see.)
Flat ground I’m only getting around 40mph. Fastest I’ve gone is 48 down a pretty steep hill. I feel like my flat ground should be higher atleast. I only weigh 125lbs. I’m thinking maybe I should lighten the weights because my flat ground is just above 8000rpm(probably like 8100 or 8200, kind of hard to tell exactly because i have an analog tach. i think it looks better.) Going down hills I touch 9000.
I’m also wondering if maybe I need to run a bit richer jets. i have an 85 jet with it right now and i did a spark plug chop test where you go wot for a minute and then just cut the engine. The tip was like a light grey with some ‘coffee brown’ spots on it. I’ve read it should be that color all the way around.
I honestly don’t really know too much about mechanical stuff, but working on this little 49cc GET engine has taught me so much and that’s the most fun thing about it to me. It feels like a really great first project.
Any direction or input on this would be appreciated. Maybe the engine is just a little too old(its around 8500k miles now), maybe I just have false expectations, or maybe I’m overlooking something simple. Thanks guys
