  1. Actually, the rifling of the bores has at least one demonstrable benefit, which is that it reduces the amount of material used, so makes the parts cheaper to print (one of the metrics used to determine part cost is how much raw material is used). I've always been curious to make a smooth bore version and compare performance but that would be a big waste of time and money.
  2. Have you ever had a part of the size and complexity of those intakes quoted for CNC machining? Or any other manufacturing process? Yeah, good luck, get back to me on that. If it was even possible to make them on the latest greatest 5 axis CNC machine, and get someone to agree to make it for you, you'd have to sell a kidney to afford it. Have you ever bought CNC machined velocity stacks for any other performance bike? I have. I got a set of aluminum stacks for my Daytona 675. Very simple geometry, made on a lathe, not a mill. They cost well north of $300. Given the fact that these are designed to match the rubber intakes on our throttle bodies on one end, and to perfectly mate with the inside of the air filter ensuring no air leaks and a tight secure fit, and can be made on demand with no setup costs or special tooling, yes, this is quite "affordable". That doesn't necessarily mean everyone can justify buying them, and no one is putting a gun to your head and forcing you to. In fact I find it quite hilarious that you're moaning about their cost when you're going on at every opportunity about the upgrades you're allegedly going to perform on your bike, such as a hand made multi hundred dollar oil pump that has no demonstrable benefit over the stock equipment. You want to run a different setup, that's fine. But to complain about the cost of these parts demonstrates some ignorance about the cost of making custom parts and the unique benefits of 3D printing in general. Good luck securing those filters though! Especially that top one, looks like it will come flying off at the first turn you take over 40 mph.
  3. I really love your 30 amp circuit breaker solution. When I re-wire the bike this winter with an m-unit, I will totally steal this idea for the one and only fuse that will still be needed for the charging circuit.
  4. I truly admire and appreciate your dedication to maintaining your bike and the knowledge you share so clearly with our little community.
  5. and extra timing chains for the bedroom
  6. One of the things that I used to find annoying on my cb350 is the crossover tube linking both sides of the tank. It would make it really messy to remove the tank without spilling gas everywhere. Until I discovered Goodridge makes really nice stainless steel quick disconnects for fuel lines. Now thinking the v11 tank would really benefit from a crossover line in the same place... 🤷‍♂️
  7. How about on the later model tanks with internal pumps on the right side? That's what I'm running on mine. I ran it out of gas once, luckily only about thirty yards from a gas station.
  8. I wish this was a component that could be upgraded... Which actually reminds me, been meaning to ask: how much available fuel is theoretically left in the tank when the light goes on?
  9. I think I might just keep an eye on it and wait until the off season.
  10. Hah! So this is a common thing then. That's a bit of a relief. I like the idea of gluing a dime over it, very retro lol

    My Guzzi, from when I got her until now
  12. So, lately while riding my neutral light has been blinking out, flickering, displaying weakly, then coming back full brightness, then going out again, without any apparent reason. Wiggling the gear lever sometimes brings it back, sometimes doesn't. Then it comes back again on its own. This is annoying, but I have a good feel for the bike's shifting so not really a big deal, I can find neutral without it. Figured I'd eventually get in there and figure it out when I had a moment. Today I thought I'd take a look down there, not to take anything apart but just take a peek to see if there was anything visibly wrong, like the connector being loose. Lo and behold, there is a good amount of oil weeping out of the hole right above it, where it seems like one of the selector wheels is housed on the other side. Didn't have time to do anything about it, just snapped a photo and muttered some curses. Anyone else had this problem? Any ideas what it might be? Mine is an early 01 model. I redid the selector assembly with the updated spring first thing when I bought the bike about six years ago...
  13. I've been teying to determine why the Caruso oil pump is worthwhile, all I get is some judgemental pablum about "quality". Why don't -you- tell me why, again other than the fact that it look nice. Docc's bike has over 100k miles on his. So again, what is the benefit of this pump?
  14. Heh, funny, I remember a few years ago you were giving me shit for using Ti fasteners, saying I was wasting my money. Good times!
  15. Hmmm, looking at parts fiches for the MGS-01 and comparing to the V11, they appear to have the same oil pump and the same relief valve: MGS-01 https://www.af1racing.com/store/ProdImages/st3/GU076.pdf V11 https://www.af1racing.com/store/ProdImages/st3/GU016.pdf Higher oil pressure has been touted as one of the benefits of upgrading to the Caruso oil pump. MartyNZ countered that higher oil pressure would just result in the relief valve dumping the oil in the sump. Thereby negating the alleged benefit of higher oil pressure from the pump.
  16. So now the question begs.... can the relief valve from the MGS-01 be fitted to the V11 (assuming it would be designed to work with higher oil pressures from a higher capacity pump) ?
  17. This (among other things you wrote) is a very good insight. Thanks for posting.
  18. Yes, you did, thank you. I was addressing your unsolicited pontification on the topic of Quality.
  19. lol, looks like someone has been reading Zen and the Art of Motorcycle Maintenance, perhaps taking it a little too closely to heart. As I said up thread, I understand the value of better engineered parts. There is such thing as "gilding the lily" though. Quality for quality's sake is nice, but personally I'm more pragmatic than that. I want performance or longevity improvements for my money. I'ld happily plunk down the cash for an oil pump hand whittled by Leonardo Da Vinci, raised from the the dead, crafted lovingly from a solid block of platinum, but only if there was an actual measurable benefit for it. But if the stock Guzzi pump does the same job, despite being uglier or less refined, then it's staying. I'll spend my money on something else. Like a nice paint job.
  20. you should totally do that

    thank you! 🙏 still a few things to improve on, but she's definitely a peach.
  22. I'm still unclear as to what this pump does differently or better than the stock one. I have a set of the Caruso wheels, am planning on doing the swap at the end of the season. I understand the value of better engineered stuff, but "better engineered" has by definition a set of criteria and metrics by which you can say it is better. So other than the craftsmanship that went into making it, what does this pump do better than the stock one? Is it longer lasting before it wears out? Does it pump more oil? The difference in idler gear, for instance, what is the benefit of that?
