No power

[bscoot]

I have acquired a 2020 Ruckus with 900 miles on it. It is super clean. I idles fine but has no power. It couldn’t pull a sausage off the table. I have tried several things. Compression is 185. Leak down was 2%
Spark plug looks good. Carb is clean ,float height was 13 mm, I ran it on a remote bottle with same results. I’m not losing spark. Air filter is clean and installed correctly.
When I start it on my bike lift , I can rev it up great but if I hold the brake it falls on it’s face and dies / stalls.
My friend and I are stumped. I forgot, we also did the reset with the red connector to the battery.
I really hope someone can shed some light on this.
Thanks in advance.

Here's my best guess for you assuming the engine is as minty as a 900mile engine should be. Check your clutch to see if it is somehow siezed to the bell. Since we have a CVT in our Rucks if the clutch doesn't disengage when you put the brake on you'll stall the engine. I have a clutch bell that will bind up on the clutch pulley causing a similar issue as yours. When its up on the stand it'll be fine, rev up no issue, but if the brake comes on it stalls and dies. Hope this helps!

Thanks Baizy, I was using the brake on the lift because it was getting old trying some , taking off the table , outside to test ride. Monday I will pull off the CVT cover and check her out.
