Day 16
New cams take a 21mm wrench to turn. Bought open end wrench from Home Depot, cut it short to fit under the frame. Also used cutting wheel to slim the head of the wrench for more range.
Most excellent "how to" on setting the timing here. I've done it before, but following this guide made it 10X easier. One again, @
R-III-R Turbo
Day 17
Set timing then checked valve clearances. Many were predictably off. Order more shims, and wait.
Day 18
Cams out, new shims in, set timing, check clearances- still some are off. How the fock does that happen?
Cams back out, replaced shims, set timing, clearances dead on
perfect, except one (in spec on loose side of range). Calling it done!
Triple checked timing – good!
Day 18
Reinstall clutch cover. Don’t attempt to wind the spring by over turning the arm (you may have to
slightly). The spring is
not what returns your lever at the grip. It is the actual clutch springs that do most of that work. The spring on the cover is to ensure you have a bit of slack in the cable. Thanks, again,
@warp9.9
Replace clutch cable
Day 19
Radiator, throttle, K&N filters, coolant recovery tank, front wheel and gas tank back on. Starting to look like a motorcycle again.
Added the clear tube mod so you can see your radiator overflow tank level- highly recommended. Thank you
@Brennus Radiator overflow sight gauge modification
Day 20
Exhaust back on. Battery installed + extra ground cable. OK, feeling some dread...
Will she start?....
Oh, yeah, she Fckn Runs!!!
Day 21
Installed Neville's Starter Tune using TuneEcu and installed Power Commander 3 for the tuner.

Finding the main connection point was hard. It’s at the very bottom of the wiring nest near the first spark plug, a little behind the coolant recovery tank
Day 22
Trailered it to the tuner. He ran into multiple problems and after a loooong day I ended up with a less than perfect tune. Most of the issues were on my end. First, don’t be “smart” and spin the clamp for the throttle bodies so it’ll be easier to get to later- turns out that the throttle assembly was stopping on that clamp and no way to get WOT. We fixed that on the spot. Second, I must have gotten a bad tank of gas before the tune and then it sat for 7 weeks while I worked on it. I should have drained the tank and put in fresh, high-quality premium fuel before visiting the tuner.
Day 23…..
The bike had a bad buck at around 3700 that improved greatly with my first fresh tank of fuel- thus the diagnosis about bad gas above. Gets better with every fueling.
Dyno said 195HP and 174 Torque. Bike runs strong and pulls hard, but not running at full potential and still has some misses in the mid 3,000 rpm range. Wheel lifts without a whole lot of effort, but I know that "there’s still more gold in them there hills."
Day 24
Compression test is 25 psi above stock readings I took earlier. The gauge is consistent in readings, but reads low, so numbers themselves are probably meaningless, but I was able to put to rest a nagging suspicion that I botched the rings on install of piston #1. Plugs all look good and consistent.
Day 25
Checked and crimped all coil wires. Grounded a screwdriver and passed it over the plug wires looking for a jump indicating a bad wire, but all appeared to be OK. Ordered and installed a new fuel filter and primary TPS- just want to make sure everything is right when I get it to the tuner. I felt a definite difference, which I believe was the new fuel filter. Now I have a spare TPS.
Looking at another tuner for various reasons.
Day 26
About five weeks later I rode over to Lee’s Performance in Charlotte, NC. Lee is the real deal… According to his website “We are the home of the outright WORLDS FASTEST HAYABUSA at 260.288 mph, and in 1999 we were the first and fastest Hayabusa to go 200.00mph ridden by Lee Shierts.”
Result = 206HP and 181 torque
Now, finally, she pulls hard and smooth through all the gears and if I’m not careful
the front wheel lifts, unless the back wheel spins first. What a BEAST!
I’m proud to be able to say that I did the work myself (with a lot of helpful advice from folks here), but it did take
much longer (often waiting for parts) and cost a bit more, because of additional install parts and tools, than I expected. Getting to and replacing the pistons/rings was definitely the most difficult part for me as a first-timer.
I feel that I had a lot of luck along the way, considering my lack of knowledge and mechanical skill. I often tend to jump into things headfirst. For example, at this moment, I am covered in a severe rash, arms, neck, entire (I mean
entire) thigh area, and on my face. My eyes are nearly swollen shut. I look like
Jack Nicholson
When I was cutting trees on the property and came upon a 8" diameter vine, I paused for a second, wondering IF, could it be?.... right before laying right into it with the chainsaw- dust kicking back in a cloud over me. Oh, yeah, I was absolutely right... poison ivy.
In hindsight, I might have just gone with the street cams and left well enough alone. Or, I could have paid a qualified mechanic to do the whole enchilada, but then I wouldn’t have had the
once-in-a-lifetime experience, which really has been priceless!
I'm literally itching to get out for another ride- just as soon as this darn rash settles down.
