5 rides in a row with total overall success each time.
I think I finally figured out the magic combination, for me at least.
While there still is a flat spot at lower rpms (3500) and larger throttle openings ( bwuuuuuu-aaaah), it's much better, and I can safely say that all seat of the pants tuning is complete.
This flat spot does make it hard to pull the next gear early when at 'race pace', and that is my only gripe that is left. I have to stay above 5000 rpms to never feel it.
At non-race pace, it doesn't matter, as the carb tunings work fantastic at partial throttle. Torque for days.
Next will be the on-board A/F ratio meter to see if I can fix that flat spot....which I believe to be crappy cam timing by Hotcams, but we shall see.
What my bike will do that a stock WR would not do for me:
- Climb any hill I have the balls for, without gearing down (14/51), and without worry of the rear end hopping around and loosing traction. 2nd or 3rd gear baby!
- Not shift so much on flowing single track. Shift up, use the clutch, and torque monster around everything.
- 165 main, 45p, R&D screw, stock YZ air/power/needle/needle jet(s)
- TPS calibrated to .76 volts with slide closed 100%, 4.6 volts at 3/8 throttle opening (via Dynatek software+pc)
- Partial throttle control: the throttle tube now acts like a reostate(above 3500 rpms), and you can order power like ordering a pizza.
- Hold the front wheel up when needed: climing a slightly rutted incline, I can actually keep the front wheel in the air to keep from getting sucked into a rut. The rear does not wallow and mess up the wheelie, and the throttle control allows me to keep it going (for what is not very long but seems like days)
- R&D powerbowl-2, FMF carb wing, Dynatek mapping
- Snap to attention with throttle: the suspension tuning has given me the above rear wheel control, without any wallow or feeling of detachment, and no squating
- Hold a line! I am now able to set my suspension stiff enough that undulating terrain does not affect my holding a razor thin line, without killing my hands/shoulders
- Jump! I don't mean track doubles (meh) I mean water diverting ramps used all over so Cal hills to prevent water rutting. Now I can hit them with confidence and FLY. Before, it felt like I was jumping a Garbage Truck....every landing was really messy.
- Ebay 2006 YZ forks and shock / Steric Racing suspension tuning, with 30cc lower oil height than stock .56/6.3
- backing off the high speed compression on the rear to 40% if max
- 21.5mm offset DHR triple clamp set (came with bike)
- Drift: I can drift for days, without having a problem when there is a drop out in the terrian. Even rocks.
- Two wheel drift: now I can come into a flat corner too hot, and control the front, rear, or both, like I knew what I was doing. It's a fvcking great feeling
- Kenda Milleville-2 120/100/18 rear tire , Bridgestone 90/100/21 front tire, 8lbs and 14lbs
- Run in Fourth Gear where I usually ran in second. This allows for zero engine breaking, making down hills so smooth, and no rear wheel hop. (Brakes)
- Dynatek ignition mapping
I probably forgot a few hundred other details, but that's the broad stroke.
Problems not solved;
Clutch drag (stock clutch pack and hole-ing it to solve?)
Flat spot at large throttle/low rpm (A/F meter for tighter jetting work)
Seat: my home made tall seat is a bit 'un-comfly' on long rides
