Hiccups....

It's May 22, 2011

Took my bike to the local track, the poor thing wasn't making power over 9000rpm.

Got it home, took apart the blower drive. Found the outboard support bearing had spectacularly failed. Both races discolored blue, some grind marks from the pulley on the bracket face.

Sent off an email to the kit maker. Sent the parts back to him.

Seems the bearing company sent the wrong clearance bearings, and upon exam, the kawi crankshaft end is not square to the axis of rotation, resulting in a small amount of runout as the crank spun. This runout loaded the bearing races to failure.

The fix.

 The outboard bearing is engineering overkill anyway as the overhang is short, so a simple seal where the bearing was is the solution. A+A tested a proto bike for a week without issue.

Since the bike was apart anyway, I went ahead and ordered the 10psi pulley( Stock one goes to 8.). I have a cruiser/everyday bike (Triumph Rocket), so the ninja is becoming my toy/trackday beast. Should be fun.

 Hoping to have a dyno sheet this week for y'all.
