  2. As mentioned, they do have minimum pressure, in particular (the one that gets all the attention) is the minimum front tire pressure. Michelin set this minimum, in theory, to stop front tire failures that result from running air pressures too low. It must be said, however, that in the era of Michelin being the spec tire supplier there has not been a tire failure from running too low air pressure in the tire. On the other side of that coin, it turns out that best performance of the Michelin front tire occurs at a pressure below the minimum pressure set by Michelin. That makes no sense. Why would you design a tire that performs best at an air pressure you claim is below safety limits? To further complicate things, whether you are running out in front in clean air or behind another racer has a large impact on how hot your front tire gets, and how hot a tire gets directly affects the air pressure inside that tire (as temp goes up, air pressure goes up). So, racers are left trying to guess what front tire air pressure they need to start the race with to keep their front tire pressure above the minimum set by Michelin for at least 60% of the race. It is a balancing act, too much air pressure and they will be slow. Too little air pressure and they will get a penalty. It is not as simple as set it here or above and you are fine, as your front tire pressure will vary depending on whether you are out front or directly behind someone. This was famously shown recently when Marc Marquez pulled over to let his brother by so he could run directly behind him to bring up his front tire pressure. Once he had done enough of the race with his front tire pressure thus elevated, he passed his brother and ran off in front using a tire with air pressure below the minimum value. The rules are so stupid that what Marc did was perfectly legal. Had Vinales paid better attention to his front tire pressure, they typically have a display on their dash telling them what their front tire pressure is and / or whether it is above the minimum value, he may have avoided leading the laps he led to stay in behind Marc to keep his front tire pressure higher. We don't know the details, because they don't tell us things like how low his pressure was and for how much of the race it was. All we know is that his front tire pressure was below the minimum for more then 40% of the race. What was messed up the most was, they should know all this real time, but they only announced the penalty for Vinales around two hours after the race, after he already stood on the podium and got his second place trophy. The rule is stupid, but that was incompetence.

  3. It looks to me like the front end has been rebuilt/repaired from parts, silver wheel fender, prior fork comments, so maybe has a crash history.

  7. For me, I find the cast Frame Side Plates ("stilettos") of our V11 Spine Frames, and the Centauro/1100 Sport-i, to be objects of absolute beauty. The original Daytona/ SPOrT 1100 side plates? "These things are industrial grade. Almost indestructable" -Starlord

  12. As Phil said, those hairs won't cause anything. You may want to adjust the air pressure in the tire(s) that feel "squirmy". I would guess lowering the air pressure would be the way to go, but it could also be you need to raise the air pressure a small amount. If you adjust the air pressure, you would typically do it in small steps, maybe a pound or two (not sure what the Bar equivalent would be, likely a tenth of a bar or two). A good way to tell if your air pressure is right is to measure the tires pressure cold and then ride the bike as normal. Stop the ride and check the air pressure while the tires are "hot". That increase in temp causes an increase in pressure. That increase in pressure should be around 10% - 15%. If the tire pressures don't increase enough, lower the tire pressure. If the pressure increases too much cold to hot, add pressure. It could be the tires simply need to bed in, as mentioned tires generally have mold release to help them come out of the manufacturing molds that give the tires their tread pattern. That mold release tends to be slippery.

  13. I also found out that nobody pull the dipstick out any longer. Now, my 911 has an electronic oil level indicator, but I don't rely on it. I physically check the oil and other fluid levels. I am told that you no longer need to worry about oil changes mileage, since cars tell you when it is time to change it. No need to check your rearview mirrors either, you have radars. Soon, no need to watch the road since cars are going to drive themselves... or maybe not?

  15. I'm not so enamored, nor prefer the early ones. But hey, *something* has to be there and get to all the attachment points...form follows function. I haven't looked close enough to ask whether the later style are cast or forged...I'm guessing cast. It appears by the picture that the earlier porkchops had a narrower swingarm through the pivot. I can't recall on the 'Sport whether they're flat, or widened, or in between. Ah, pic says wider;

  16. The original Moto Guzzi (spine) Frame Side Plates were on Dr. John's 1987 (2-valve/square fin) ProTwins racer. That first SpineFrame was hand built in Pennsylvania and the side plates (which Dr. John was quoted as saying, "They are a great place to stuff a sandwich " [paraphrase] ) are inscribed "HOLLOWAY" on the left and "DR JOHN" on the right. Get the book, you'll love it . . . reference courtesy of https://www.motoitaliane.it/en/prodotto/dr-johns-moto-guzzi/

  17. They're called "wreckers" in Australia. They exist in Germany too, with names like "Autorecycling" or "Autoverwertung". "Verwertung" means things like "utilisation", "recovery", "reutilisation" and so on.

  18. I still have two you-pull-it junkyards nearby. The best one is "Snake Road Auto Salvage". Snake Road in South Florida wasn't, and isn't, a joke. My first car was a beat-up '66 MGB I bought for $35 in 1978. I shod it with bias-ply junkyard tires, and they really got attention drifting corners on the wire wheels.

  19. Just pushed the forks up you mean? Yeah, I think so too. This picture from the facebook advert shows forks that appear to have compression damping in the left leg, and rebound in the right. As far as I know, that would be the 40 mm forks from the earliest models with the clip-ons under the triple-clamps, wouldn't it?

  20. Here's a picture: What the arrows are pointing at are the remains of the almost completely scrubbed off row next to the the groove in the centre. The dots that are visible are the stumps of sprues that are gone. When it was new, it had stand-up-and-be-proud sprues all over, four to each tread block, more or less. Not very elegant, but as I wrote further up, it is a small manufacturer, and the tyres are relatively cheap for the more than adequate performance they offer. Looking at it again today, I can't imagine that the sprues have absolutely no effect. There are so many of them. How much effect is, however, difficult to guess. What @Grant mentioned is something I am aware of. The coating is a silicon compound that is put in the mould (sprayed in, I suppose...) to allow the tyre to release easily from the mould. The shops here, and in Australia if I remember correctly, generally tell you to take it easy for 100 km or so. I had already done about 100 km on the tyre, but nearly all of it at in-town speeds, and temperatures below 10°C, so the tyre wasn't likely to have been really warm. I'm thinking the squirming was likely a combination of the remains of the sprues and some still not quite scrubbed off remains of the silicon stuff. I'll take it a bit easier next time out, and give the tyre a chance to scrub in a bit more.

  23. Both wheels off at the same time? Best practice is to tie it off ("chain fall ") from the joists, above, in addition to your jacking method. Belt AND suspenders? Definitely. It's worth for that ONE time that one fails without a backup. Don't ask me how I know . . .

  26. You can put anything down in the spark plug hole that will come out in the same amount that was installed. You will be barring this crank over so you will be able to pull the rod out while you are barring the engine over finding TDC. I used a 18" 1/4" extension to find TDC on a Nissan Titan yesterday using a LONG handle 1/2" drive ratchet on the c/shaft to bar it over . Take it slow n take it easy . We have professionals and novices on here , for the ones that know a lot feel free to add input or corrections . For the beginners don't be afraid to as if you're not sure. Everyone here is glad to assist. HTH.

  27. I wasn't sure about the fork diameter. But that's easy to find out: Google pointed me to this topic: So the Rosso Mandello clipons won't fit your 2004 V11 Sport. Sorry for the confusion!

  28. Thats Motogp these days. WSBK is heading there tyre wise though. At the Phillip Island round this year about 3 weeks before the event Pirelli the tyre supplier announced that their tyres wouldn't make the full race distance and both main races would require a mandatory pit stop. This totally ruins the whole meeting turning it into 5 sprint races with confusing minimum pit time requirements and disadvantages riders that can conserve tyres and come on strong at the end of the race. Even the riders after a day of practice were saying they had zero issues with tyre wear. Money, technology and stupid officialdom and manufacturers fearing litigation no matter how remote rule racing these days.
