What else is wrong in my 2004 manual?
Just for clarity, I'm cool with manuals, but when my personal experience has shown that something works better even when it's not right by the book on my bike, I share.
My bikes all steer smooth as glass, with light effort, at speed or at a crawl. I check the flop cuz that's what I learned from old men, and when the front starts feeling loose to me, 10 times out of 10 it will flop. Sorry for any confusion I may have caused, but we did find out that there's "issues" with the maintenance bible, didn't we?
No problem here, I'm hoping Scott will chime in again regarding the the effect the 13 ft lbs has on the fork travel when the front end is off the ground. Your input is noted, and I can see where a little more pressure/resistance on the steering in the turns would be beneficial. I have stowed away your comments for future reference when I'm tinkering on it. 
I don't know if we ever did figure out how to get 5000RPMs out of a 99-03 1600 to test the charging system

I tightened mine pretty tight. Wish I had had one of those wrenches I saw on here a while ago, could have set the torque correctly. Anyway it eases over to the right or left - not too fast but just right. I'll have to look the wrench up before I pack them again.
The 5,000 rpm spec is rotor speed which is about 2,500 engine speed give or take. Seems like I remember reading that the alternator rotor is spinning twice engine speed. Still, they could have explained that better. |

Thankyou ever so much for the comments Scott, I appreciate it.

That would make more sense. I was not aware of a difference between the rotor speed and the crank speed. Guess I'm thinking Parallel motors and fours, where they tack them on te end of the crank opposite the clutch all the time. I know the 5000 RPM output is a common reference point. My SV650, EX500, EN454, VN750, VT750, and VT1100 ALL used 5000 RPM as the max output reference point. Maybe that has something to do with the frequency of the AC voltage coming off them. It could be that that is the point where the output sine wave is the most consistient.
I don't know! I'm a structures guy, not an electrician! I can read a print and chase a few sparks, but Ohm's Law and Watt's law are not tatooed on my brain! |

Scott, I think I know what you are talking about with the "eases over" I sometimes refer to that as "close enough for government work"! You sure can tell if they are happy or not when you go down the road.

OK I tore down the front end and found the top ring nut spinning freely, no tension at all on the rubber washer, and the lower nut no where near tight let alone the torque specs listed in the manuals. Funny thing, the tabbed washer was there. My guess is it was assembled improperly. Bearings were good. Cleaned and repacked. Tightened nuts per advice on here. Did the flop check and grabbed the forks and wiggled up and down. All good. Took a ride and no more squeek. And suprise suprise the wobble I thought was air pressure related is gone too
jd thanks for the advice, CruiserBob thanks for the tech article, and thanks to all of you who pointed me in the right direction. You all saved me a whole bunch of money! |

Glad that fixed you up. Confidence in the front end has a huge effect on how much you enjoy your bike. I guess that's why I'm so fixated on these posts when they come up.
Happy and safe riding with your newly sharp handling!
On Loctite on the upper jam nut: Shouldn't the upper triple clamp plate be pulled down on that nut when you torque the outer stem nut to a bajillion pounds, and pretty much lock it in place?
That's what the cross-section looks like in my mind's eye. Locking (tab) washer in between upper nut and triple clamp, of course.
