Primary chain was JUST past the loose spec cold, tweaked. Filled with ATF as suggested to clean things out. I also adjusted the shifter knuckle as prior owner had it at an odd angle to get the shifter lower, now it's parallel with the shifter and shifting is worlds better. Not sportbike light, but workable, and I can now clutchless shift again, though man what a flywheel effect, roll off, and WAIT if you don't wanna lurch forward on the upshift.
Pulled the front rotor, cleaned with scotch brite and brake clean, reinstalled, verified rotor float at all mounts, invented new curse words trying to mount the whole setup solo... still judders horribly, pulsing can be felt in the lever. The caliper isn't doing a good job retracting when you let off either, it needs to be torn down, cleaned and rebuilt, on top of new pads and now I'm going to say new rotor as well.
Now, my test ride... first opportunity to ride on roads I know, and... that bike wants to play. My Pan Am is refined and fast, this thing isn't quick, but so damn raw it's addicting. (Warning, no offense is meant by the following comparison!) It reminds me of when I started out racing pitbikes, once you built them past a certain point they just got, raw feeling, any attempts by the OEM to damp out vibrations, stabilize things, etc were just overwhelmed and even though they weren't quick compared to full size bikes they were a riot to ride. I'm getting that same nothing between me and the violence under me feeling and, yeah, that's fun! This bike and I will get along JUUUUUST fine.
I did run into an issue though, on my way back, wicking it up a bit more and getting some full throttle yanks in it died on me a couple times in a row while under high load, like I hit the kill switch. Close the throttle, coast for a min without letting the engine stall out and it'd come back to life. I figured low fuel, and either the light is out or the sending unit is bad, easy. Eased it down to the gas station and it only took 3gal to fill, so... that wasn't it. On the way home it threw the check engine, in my driveway idling for a min the check engine went out but it would randomly cough and miss a beat, nearly stalling so something's not happy. I assume the ECU has some stored codes functionality I can access with the buelltooth that came with it? Bike as a 'Race Only' ECU on it, I assume that means it's not looking for the exhaust servo, theoretically it got intake seals done by a shop in the past year or two as well.
