Ninja 250 High Compression Motor Installation

Watch as I install a newly machined high compression ninja 250 motor into my racing motorcycle. Be sure to check out the links below, including my machinist, Cassandra D and Vortex Racing, Legion SBK race series, as well as a video link to changing a clutch on a ninja 250.

"Here's a picture of my welds" 🤣🤣☠☠☠☠ - Looked like this motor worked very well. Awesome seeing what you've done with that bike!

I've an ninja 2012 fi model.. Stock piston is 62 mm...i want to upgrade 63.5 ! What should i change NOW ??

[@Extra-Medium-Skills]

Find a good machine shop first. Check reviews on piston kits as well as the forums for info.

For Torque & top speed what exactly the chain sprocket combination ?? 14/40... Or 15/41....??

[@Extra-Medium-Skills]

I run 14/44 on my racebike. But, I have a 180 rear tire. The larger the front sprocket, the higher your top speed will be, assuming same size rear sprocket.

What was the previous motor?

[@Extra-Medium-Skills]

Previous motor was a 1999 Ninja 250 motor. The old motor’s compression had fallen below 135psi on crank testing…. Still started and ran, but I needed an upgrade!
