#15 - Starting To Come Together

Took the bike out for a shakedown today.  New narrow bars are so much fun! I should have do e this ages ago.  Those I am very happy with, just need to pick up some longer bolts for the risers, in the name of safety.

New increased fuel pressure worked out great, I've had to trim fuel out everywhere, the full throttle ratios have fallen into the 11 or 12 AFR, right what I'd hoped for, now I have headroom.

Steering Damper, great function, almost transparent but removed my higher speed wobbles and the jarring effect crossing bumps and joints leaned over, overall just smoothed the steering response out.

New TPS fixed the erratic activity at 1-2 percent throttle, now it's a consistent response to minor inputs.

Throttle body balance improved the feel a bit, they're "exactly" right now.  All even vacuum across the three.  I removed the vacuum reservoir I was trying, no appreciable effect with or without.

Going to 9 range plugs instead of 8s, and coil on plug conversion yielded a much sharper throttle response than before, it's snappy as all hell, a little sharper than I want actually.  I'll be pulling some timing out of the 1200-2200 RPM range, it's hard to ride smoothly at the moment.

The ride couldn't be all roses though, brake line banjo leaked, front brakes went away.

Crank case evac setup needs a different check valve, the Supra PCV allows too much back and forth flow with the pulses of the exhaust, at least at low RPM.

Mix is quite lean at 1-2 percent throttle from 1800-2400, where I was having issues with the TPS, but, since it's consistent now, I can tune that out finally.

Starting to look and feel like a land speed bike, when it gets cold, I'll drill and wire all the requesit bolts and nuts, and Fab up the number panels / mounts for them.

Mufasa is an absolute bonkers bike, rowdy, angry, and a hell of a lot of fun!  Really looking forward to bigger came that'll bleed off some of the extreme compression ratio!

OH and then there's this, which I am going to tear down over the colder months and do some prototype work on :P
