After damn near 10 valve services on my Ninja 250, I'm pretty happy the Ninja 400 valve maintenance interval is double -- once every 15,000 miles :rock:

Not quite Yamaha-levels of awesome (they tend to set the interval at 26,000 miles) but 15k is definitely better than 7.5k miles. Full maintenance schedule below.
