Oh, and next valve adjustment (130,000 miles/ 209.000 km), I really should replace the original valve cover gaskets. Get-me some o' those hi-zoot Valpolini . . .

A week ago I posted concerns about replacing my original fuel pump at 125,000 miles/ 201.000 km. Turned out that restart stumbling was a fluke, perhaps a bit of "vapor lock." Has not recurred, so I moved on the my 5,000 mile/8.000 km oil change/ tune-up interval. Some observations: > I use the filter access cover to change the filter. Last change was the only time I found the filter stuck. This time I LIBERALLY oiled the gasket, both the surface and the sides. I remembered to inspect the old filter to be sure it brought its gasket out with it and also shone a light up into the sump with a mirror to be doubly certain no old gasket remained in the engine. I did not remember to peel the WIX sticker off the filter, but have run the label before with no issues. I prefer to remove them. "One less thing," you know. > The Sport ran so great yesterday, I was mildly surprised the spark plugs looked so awful. The gap had opened from 0.0275" to ~0.033. One side of the plugs showed a nice coloration and the other side (especially the right) was all crusted with carbon deposits. I'm thinking signs of needy valve seals/ guides. > I've been concerned my valves are sinking into the heads, especially the left exhaust. Pleasantly surprised that I relaxed the right side I/E maybe 0.0005"/0.0127mm just to get a nice, loose slide on the feeler gauge blade. I found the left side both at 0.007"/ 0.018mm, so slacked the exhaust a thousandth and snugged the intake a thousandth of an inch. Very pleased. > My TPS had drifted from 157mV to ~134mV. For the first time, I purposefully held the throttle firmly closed to set the TPS. This looked to make about a 10mV difference. I feel like I should be indexed to the map better. Thanks to all of those who have patiently helped me understand this importance. > I have been skipping the Decent Tune-up step of removing and cleaning the air bypass screws/circuit. Not sure the last time I did that, but the tips of the air screws weren't just sooty, but crusty and a lot of black gook and particle washed back out of the passageways with throttle body cleaner spray applied repeatedly until the wash-back looked clean. Again, pretty sure my old Sport is burning its share of oil via the valve seals, but I won't skip that step again. _________________________________________________________________________________________________________________________________________ Out for a warm-up ride to balance the throttle bodies and, five miles from home, she coughs hard - sputters- picks up again- coughs - sputters- barely runs or idles as I nurse her in to a safe spot. She dies, making me think about that fuel pump again. Off the bike, I retrace everything I just had my hands on. There it is: I had left the TPS break-out harness connected and the bare leads had wandered their way to ground. Detached it, plugged the TPS in directly and motored happily away. Note to self: > After setting the TPS and removing the voltmeter, see that the break-out harness is removed and TPS is plugged back in directly. ~ ~ ~ " I won't skip that step again. " ~ ~ ~

This makes mySport seem positively sane . . .

We haven't sen @Van since 2016, so I entered your edit in the first post registry. Happy to see you have your Tenni back, @Birdman !

How the Proper English would say, "If it ain't broke, don't fix it."

I wonder at when I will go for the gears. Maybe pull the sump spacer at the same time and also install my genuine MotoModa® P'Roper sump plate . . . (See also: the Rusty Star Picket Project ) (Probably no timing gears before this year's South'n SpineRaid. Yet, looking at a "Tank-off" before then for fuel/air filters, so likely install the new pump, Scud-made Shielded Fuel Line, and perhaps the LuckyPhil EZY-Glide fuel tap . . .) Just trying to make room for The Waddington Effect . . .

Takes more than a BudLite to see kangaroos in Texas. That's mescaline territory.

A kangaroo in Texas? Was this before or after the tavern stop?

Just turned 125,000 miles/ 201.000 km warming the oil for a change and tune-up. I don’t recall mySport ever running this great at tune-up time. No signs of fuel pump issues. Thinking back to the incident, it was a restart after sitting for a few minutes. Kind of classic “vapor lock” behavior ( never had this before). So, on to the tune-up. Tank off another time. Thanks for the replies and confirmation on this fuel pump!

Those are some fine looking “pressure angles” . . . [ I had to move my silly comment to match. I'll clean up the unnecessary comments related to the images. Thanks to all for reporting the issue. And thanks for reposting, @Pressureangle ! ]

That's a sharp shot, @LowRyter!

The Ducati Scrambler has been an interesting strategy for Ducati to attract a new market without having them commit to being Ducati Purists (whatever that is) or diluting the purity of the main Ducati line (whatever that is). I am happy to see the Scrambler strategy working for them. My first bike was a "Modern Retro Classic" type-thing back in 1990. With 51,000 miles on her now, I rather doubt Honda would make that mistake, again . . . "Ain't she sweet?"

Yep, happened to mySport back in 2014. Ba wheel bearing made the brake pedal weird:

Errm, like this? https://www.kawasaki.com/en-us/motorcycle/z/retro-sport/z900rs

I did post that quote out of context, yet felt the wisdom still applies. "Later year" V11 that have the dubious start wiring through the Ignition Switch began in 2002.

I would not able to sleep knowing that mySport had the worst-known relays (Tyco) poked into her sockets. If you insist on running known substandard relays, familiarize yourself with the myriad manifestations of relay failure modes. But why?

I saw this concept summed up nicely by one our treasured members: "It's wiser to plan for the ride than plan for maintenance." - @Pressureangle April 2022

Okay, I see now that your marked relay is the added "Roy Relay" to the standard five. I am surprised that you have not replaced all of your trash relays with the stellar OMRON G8HE that you are fortunate to have in hand. My advice, after seeing so many compromised and disabled V11, is to run the most reliable relay and keep the lesser relays as spares (mostly for your buddies who didn't get the memo ) . . .

I'm not sure what the umarked relays are in that V11 of @p6x, nor the marked front Start Relay. Last I looked the CIT are the best available V11 option when the OMRON G8HE is not available. The "Roy Relay" that @stewgnu speaks of is the addition of a dedicated start relay in the later V11 wiring harness that, otherwise, overburdens the Ignition Switch and leads to classic Startus Interuptus. IIRC, p6x also had this additional relay installed. First I have heard it called the "Roy Relay", but our stwegnu is a clever one, yes?

Yessir. That looks the same, $79.98US + S/H etc. from Quantum. MG Cycle is %54.56 + $11.95 S/H = $66.51US. Sp, probably $25+ cheaper. Thanks for posting this, @Pressureangle!

Pulling mySport up onto the lift last week after a short ride, I heard the fuel pump give a "screeeech", then the motor stumbled clutching up onto the lift. Stalled, restarted, pumped up, screeeched again. Ran rough, but coaxed it into the SportChock. I want to just ignore this, but also have struggled with getting her to maintain idle where I prefer (1100-1250). She has struggled to keep 1000, even after addressing tuning parameters. So, I referenced @Scud's Encyclopedia of Compatible Parts and found this MGCycle replacement fuel pump. Anyone have direct experience with this fuel pump on a SpineFrame? TIA, docc (prepping for the Eighteenth South'n SpineRaid) . . .

True, that. Just thinking about giving that Grimeca caliper the "Oro" look . . . Things like that don't matter much in a lot of cases.

I'm not sure what the image is from in Post#1. I had assumed that is Pressureangle's 1100 Sport-i, but likely not (now that I think about it). In five months, we'll have them in the same garage and conduct our usual SpineFrame brain-trust session over them . . .

I found Dupli-Color GM Gold (M) / " 60, WA 398E, AGM 0491 " a close match for the Brembo oro, if a little dark.
