  1. I thought the TPS should be set around 520mv at idle after setting the base line at 150. Memory sketchy but how are you coming to that TPS value?

    That's true, yet, as it turns out, the TPS setting is what indexes the map to the throttle opening, so it is really only the baseline that is critical (with the throttle plate completely closed: no linkage, no stop screw, no high idle cam, no dirty bore).  Then the idle setting can be anywhere the bike is happy to tick over (Guzzi says 1050 +/- 50, but my Sport seems "happier" a tick or so higher.)

     

    Meinolf tells us 157mV is the correct value (versus Guzzi's 150mV). I've learned to believe him. :thumbsup:

  2. Welldone, Drewteague! Thanks for posting the gallery! :thumbsup:

     

    So, block both holes, not just one? How about a LocTite product on the set screws (instead of welding) so one (or both, even) could be removed later, if necessary?

     

    Also, worth noting on fork oil "weight" that SAE is not very accurate. One manufacturer's 5wt could be another's 10wt.  The BelRay 5wt I like is 19.50 cSt (centiStokes). Peter Verdone has shared some good data on this more accurate viscosity measure:

    [Hey, I edited posts #12 and 14 to clarify the year of manufacture 10th character in the VIN (W=1999, Y=2000). I don't recall any 1999 V11 in The States.  While this is an aside to the thread topic, this is also how we learn and share. :nerd::mg::bier: ]

  3. Spent two weeks in Italy in mid-Sept, only saw 1 Guzzi.  A tonti frame in need of some TLC riding around in central Rome.

     

    That was it, drove all over Southern Italy and didn't spot any others.  Very surprising.

    Maybe different north of Milan?

  4. There were two different Marzocchi forks on the early Sport (1999-2001), on one: the axle is nutted; and the other: the axle threads into the left fork leg.

     

    These are all 43mm USD, as I recall. (there will be another part number in the system for the black finish on the 2001 Rosso Mandello.

     

    @Drewteague, can you confirm the build date (left headstock tag, month-year), 10th VIN character (W= 1999, Y= 2000, and the fork type (nutted or screwed in)?

     

    (I've never heard of a 1999 Sport in the US. So, it may have a couple other features that might inform your suspension set-up.)

  5. Yeah, well, getting your advice on the internet from a guy who recently threw his driveshaft is sketchy in the least! :rolleyes:

     

    You're right, the early Sport 1100 had no rubber cush drive in the rear wheel. I'm pretty sure that appeared on the 1100Sport-i (?)

     

    Apparently, the manual language about changing the driveshaft was a "cut and paste" from the Daytona which had no provision for shaft lubrication.

     

    At some point, I am going to remove the front half of my (original, 109,000+ mile/176.000+ km) drive shaft and disassemble the U-joint. It is going to be very interesting to see what condition it is in. :nerd:

     

    If your play has changed of late, check all of those rear bearings and the reaction rod bushings. :luigi:

  6. Lately, I have been so thrilled with the Sport's corner entry and roll on because my previous "play" is virtually gone. Part of it was that I had let the shaft's pinch bolts (front and rear) get loose over time and the other major factor was the loose gearbox input hub that's been on the bike since gearbox warranty replacement in 2003.  What a joy to have that all tightened up!

     

    I am uncertain about the acceptable rotational play, but mine does exactly what your video shows (if not more). At the South'nSpineRaid, danl put a dial indicator on several spine frame bikes and measured the radial (side to side/ up and down) play and found most of the bikes at 0.010-0.015". I believe he said his early Sport is 0.025".

     

    Another area to check for perceived driveline lash are all the wheel bearings, reardrive bearings and swingarm bearings.  Also, the bushings in the ends of the torque reaction rod.

     

    BTW, the reardrive drain plug has a magnet on it. Don't be surprised to find "fuzz." (But no chunks, shards, or flakes! :o )

  7. I'm due to repaint mine (again). The zinc chromate was fun, but I'm thinking satin back to obscure the silhouette effect of the horns and oil cooler.

     

    BTW, what is the little "tongue" extension that sticks down below the cover?   :huh2:   (I think I'll leave it silver since it gets blasted the most.)

  8.  

     

    Polished plug wires!

    Uhhh, Docc.. you may have a problem.. :whistle:

     

     

    This is no secret! :blink:

     

    Original plug wires Docc?

     Yep. Plug cap resistors have been changed out as well as the connection to the right coil. Resistance checked on the wires a few years back.  How many years? Hmmmm . . . . :oldgit:  A "few!"

  9. Understood, 1200rpm when smooth, power commander reading and verified with guzzidiag.

    It is hard to fathom that your ECU needs replaced.  Worst case there would be to rewrite the map to it?

     

    Sorry, but is there still a PowerCommander in the mix?

  10. Thanks, Marty! :thumbsup:

     

    I still may fit new plug wires on my next Tank Off Maintenance, but the isopropyl alcohol did clean up the splotches, then I polished the original red wires with AutoGlym polish. Worked a charm! Polished plug wires! :mg:

  11. My red plug wires are looking pretty ratty. Made worse when I sprayed the bike with SuperClean.  Mistake. Well, all the engine finning looks great, but all the hard plastic and the plug wires got white splotches. :blush:

     

    So, does anyone have some wires where they can be measured? Is one meter long enough?

     

    I was considering this NGK product hoping the shade of red is compatible:

  12. So you started with the relays in the bucket and then moved them under the tank?

    Negative. My two headlight relays (lo and hi) are still in the bucket. The two (Bosch) relays you see in the image are my right and left horn relays. The horns (FIAMM Freeway Blasters) also get hot (fused positive) from the [battery] and ground back to those frame points.
