Upgraded the Minja
So I still have the Ninja 250 I started on, I call it the Minja (mini ninja). My wife rides it, and I've taken it out when I either had my bike in the shop getting tires or when I lost my key.
So I can rail on this bike pretty hard, but the original suspension is EXTREMELY soft. Like, bouncing up and down over rough pavement, lots of movement when cornering aggressively, and it jumps when upshifting. So I thought we should upgrade the suspension. The other day when she was riding she had it leaned over and it started rocking on her due to the really bad damping on the rear shock, so SHE agreed we should upgrade the suspension.
I got Sonic Springs using the rate calculator either they or RaceTech provides, and I bought RaceTech Gold Valve Emulators, and I picked up an EX250J shock (08+ 250) for the rear.
Last Saturday, I started the project. The rear shock replacement was cake. 20 min, two bolts, on and off.
For the front, I pulled the forks completely off the bike, cleaned them, replaced the fork seals (one was leaking), and reassembled with the new springs, valves, and spacers for correct preload. While I had the fairings off I decided to do some other maintenance. I cleaned the airbox, cleaned the entire engine and transmission housing of road grime and leaked oil gunk, and adjusted the valve clearances.
It rides SOO much better. I can clutchless shift through the first 3 or 4 gears with the throttle pinned and it goes like it's on a guide rail. No more bouncing or floating, it brakes better, corners better. Well worth the price of the parts.
Never ride faster than you can stop
