Chasing a worsening vibration problem that manifested itself mightily between 4000 and 5000 rpm, I did the UTB this afternoon. Did not get carried away, just cleaned up the lines somewhat, so got them within 1/2 bar (Motion=Pro merc gauge) of each other. #2 was winning the bar race to begin with, at 4 thou it was a good 2 bars ahead of the rest of the pack, with #4 running a distant 4th. Test ride revealed the motorcycle I had fallen in love with a year ago today (timing seemed right, Happy Birfday Fwankie!! :D )

Vibes reduced substantially throughout the rpm range, and the 4500 vibe that, in hot and humid weather especially, had grown horrid, to the point where 20 miles of freeway cruising at 75-80 mph reduced the hands to dead meat. The hot, humid thing was especially noticeable during CFO, and it's 90-95 degree ultra humid horrors. Finer tuning is in the forecast, with clearing vibes to come, and winds from the west at 75-140 mph...... :p Frank, by the way, has 9300 showing on the Digi-Wonder Display, and so far, is tickfreerific. And it's a good thing I scored that spare FI setup a while back, I suggest not using a screwdriver to try to hold the center throttle bar assembly in place while pressing down on the left or right adjusters, that spring disappears into the nether-regions of the engine quite nicely, thank you... :bigeyes:

Hey Rad, I did the same a few days ago and got excellent results too. I started with gauges calibrated in bar, but had difficulty. I used a conversion calculator and found that 1 bar = 75cm Hg. By switching to a more accurate instrument, I was able to get all four TB's within 2 cm Hg max deviation, both at idle and at 4250 RPM, for a much more accurate synch.

It was worth the investment in the new gauge, IMHO, to get the end result. And tell Frank I said happy B-day!

Ok I'll ask...How long did it take to find the spring?
About 1 minute. Had to unpack my spare FI system and grab one off of it. The original will not be found until winter tear down.

 
Also did the UTB yesterday. 4200 RPM buzz is significantly reduced. :)

I should be installing the PC III this weekend. Hopefully this will further eliminate the buzziness alltogether :rolleyes:

Is this a mistake spelling error? Did you mean to say now instead of not? :unsure:

 
He's a Northrider, eh. Codebook reads-

Also didn't do the UTB tommorrow. 4200 RPM buzz is now significantly reduced. :angry:

You shouldn't be installing the PC II this year. No way this will further increase the buzziness alltogether :(

Hey, don't blame the code breaker.... :D

 
Hey, at least I am now able to pilot my bike solo. :D

 
Opps I guess 1 beer too many <_<

As I meant to say earlier the buzz is now significantly reduced. :rolleyes:

Thanks to all for the very valuable info :D

Hmm, sounds like you have a beer too few... :haha:
Woodstock, you're probably right !

My UTB adjustments would be buzz free :D :D :D
