That's the flat crank version. Basic 4-cylinder inline sound. The cross plane, now that's Italian! The first 14 seconds of this video are the cross-plane engine warming up. I suspect that only tin ears dislike this sound.3 points

Sorry but you and I are on different planets with regards to what sounds good. That Video is bordering on obscene on several levels. Ciao3 points

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. " ~ ~ ~1 point

I was listening to a journalist who got to test MotoGP bikes on testing days together with the GP pilots. He was someone who competes in lesser classes I think the 300, so he is not just a scribe. He said that at Jerez, MotoGP pilots were lapping 15 seconds faster than the best of the testers. That gives a little perspective.1 point

I'm going to add some more thin layers of the dental adhesive and sand it, then maybe add something like JB Weld to the outside of the barrel. I'm still kinda hoping to find another one somewhere...1 point

I have a couple of pairs of Israeli made Brosh riding jeans, and two pair of their "cool pants" cargo pants. Brosh uses removable Kevlar panels in the hip/buttock area and T-Pro knee armor. Unless you are really tall, they fit nicely. The jeans are armored jeans, simple enough, but the cargo pants are more useful and cooler in the heat. They really believe in the Kevlar and are great folks to work with. https://brosh.com/1 point

He did have a great start to racing here in the states. It helped that the first two races were at a track he knew well (probably had more laps around COTA than the American racers). Then they went to Road Atlanta, where he had never been. He still did well there the first race, winning after the leader (Gagne) crashed. Had Gagne not crashed it did not look like Petrucci had anything for him. But, as they say, to finish first first you must finish. In the second race at Road Atlanta Petrucci's Ducati failed him, and Gagne didn't crash. So Gagne won by a mile. I do think how well Petrucci is doing says something about the level of competition here in the states. It says that the top guys here are pretty F'ing fast. Because Petrucci is a top level rider and he isn't having a cake walk here. Petrucci is running at the front, but he isn't way out in front. There are at least a couple guys here who can run with him and even beat him. That said, I like Petrucci and am glad he is racing here. I think it is good for our series. The guy is a true racer. He elevates the series, and is forcing the other competitors to step up.1 point

Racing is fickle. It runs hot and cold on riders from certain countries. At one point riders from America were hot, and they were getting the good rides, the opportunities. There have also been runs of guys from Australia. And right now it seems it is Spain. The reality is being successful at motorcycle racing is a combination of talent and opportunity. Talent is equally distributed, but opportunity isn't. Running in Europe, in particular in Spain, is useful to get you noticed, to possibly get you the opportunity. But it isn't required to develop the skills. Take Beaubier for example. He rose to the top here in America racing superbikes. The same as Spies, and most of the Americans before him. Roberts went to Europe, but it really didn't pan out for him and he came back here to race production based bikes and re-establish himself. In the end, who gets the opportunity and who doesn't is something of a lottery. No doubt as we speak somebody in some obscure part of the world is racing motorcycles and doing things most of us could never dream of. But he won't get the opportunity to race MotoGP.1 point

Haha, well, I'm not much of a "multi" guy, but really want to love the Otto Cylindri. I recall inspecting a rendition of the Moto Guzzi Otto Cylindri at an exhibit of the Guggenheim's "Art of the Motorcycle." It was fascinating to trace how all eight (maybe 14 or 15mm) open exhaust tubes traced their ways, individually, through the sinews of the motorcycle. I so longed to hear their song, thinking it must be orchestral, like eight horns of a "horn section". No digital capture will ever replicate that sonority. (Be it known that V8 afflicted me from an early and impressionable age) . . .1 point

Yeah, I am sure FQ knows Jerez. But I don't think that is as important as how well his Yamaha will do there compared to the others. If he can't get away then he risks others on bikes like the Ducati motoring past him on the straights and holding him up in the corners. Jerez doesn't have excessive straights, so he has a better shot at getting away then he will at some other tracks. At least that is the theory. But last year Fabio didn't do well at Jerez, finishing 13th. It was his worst race all year. It will be interesting to see how it goes. Joe Roberts is clearly aiming to be in MotoGP. And I hope he makes it. If he does, I will be happy for him. But between him and Cameron Beaubier I think Beaubier has accomplished more success so far and has shown more potential. But never say never, there is still hope. Roberts needs to take a step up. Maybe this win will give him the confidence he needs. But in the end he got this win because the 7 guys faster than he was that day crashed. Most of them crashed because of a freak rain and not really rider error. Only one guy was rider error. But hey, I will root for any American out there. Once upon a time American were a dominant force in GP racing. Now we are happy to have two guys in Moto2.1 point

Aproved with plates the way this bike is without any S problems is great up here. Yes l do like the Dynotech.de engines. The guy who did the mapping, yes please. Have l been looking for a anything odd in the 3000 area, nothing ,superb. Only about 300miles now, added new relays and better grounding to regulator, rest tlc winther hobby. What a fun push rod engine. IPA time, yes. Cheers Tom. Sent fra min SM-A525F via Tapatalk1 point

I've had mine off twice, once when purchased and once to install my Roper Plate. Neither time I saw anything of note, and I'll not take it off ever again without specific reason. The threads are a particular concern, and the Roper Plate causes you to lose 1/4 of the threads you had so care is warranted. Any engine block I have upside down will get all the pan holes Timeserted.1 point

My (limited) experience with paint is that if you use Rust-Oleum primer, use R-O topcoat. Many times over the years I couldn't figure how my topcoat fisheyed or peeled, until someone told me that RO use fish oil or something for their rust preventative, and other paint doesn't like it. I would use a urethane if they have it, given the ding factor of road dirt. My first rule for painting (and I do hate painting) is to let the part warm in the sun, even to the point of being uncomfortable to hold. That outgasses the pores in the part of water and oils, evaporates the carrier more quickly, allows for the cooling action of the evaporation to pull the paint back into the pores and give you great adhesion. Also you can apply a heavier coat, and second coat, much more quickly without runs. And if you like wrinkle, a hot part is the whole answer (a H-D trade secret lol)1 point

Frankly, the hardest thing about adjusting the valves is removing and replacing the alternator cover to rotate the motor to TDC "destra e sinistra ." Be aware that this operation is what strains the yellow stator output wires. Yet, this is the time to refresh our alternator cover that skims the road behind the front tire. The weather wasn't right for a clear coat, so just scrubbed it and a good coat of Carnauba wax . . .1 point

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 . . .1 point

'Why do you ride that old tractor?' My friends ask. 'You could have a modern bike for the money'. Well I have to say that although it's slow I don't get overtaken and I don't hold anyone up. I know it's un-reliable but it's never let me down, sometimes I just need to drop by old friends for a tea and a gearbox fix. I understand the ergonomics are all wrong but I still look forward to getting on it after 200 miles. I know they're unpopular but I always get company when I stop. The loud exhausts are anti-social, but everyone seems to like the noise. They call me contrary and I couldn't agree more.1 point
