Why don't you just fuck off?

Really???? 🥺

Slotted cam sprockets. Actual cam timing on any engine is usually not exactly what engine specs are due to manufacturing tolerance of various parts and cam drive stretch. Also, if you slice head for extra compression and/or remove/ use thinner cylinder base gasket for tighter squish cam timing is definitely gonna be off. So, you gotta degree cams. There could be potentially free power to be had because oem timing had reduced overlap dictated by emissions. Also, increase in compression radio basically brings valves closer to piston, you gotta check piston to valve clearance, if it is too close-boom!!!- here goes your engine. On something like cbr1000rr engine if you do any of above you cannot run OEM cam timing. P to V is that close. Usually minimum clearance is 2 mm for intake valves, you check it in 10-15 deg before TDC, and 1 mm for exhaust. It depends on individual build, but on more then one occasion I had to adjust cams to minimum piston to valve clearance. You could machine pistons to get proper clearance, but not sure how localized heat during machining would effect piston durability. Yamaha race kit manual tells you to adjust for piston to valve clearance if it is too close, and not to machine pistons. Maybe just because they want you to sell kit pistons with deeper valve pockets for outrageous amount of money. 😁

Well, I own three passports. 🤪

Why do you hate Ferrari or Lamborghini? 😁

Be careful. On the other hand proper nutrition and exercise are risk free. https://www.health.com/ozempic-vision-loss-naion-8764661

I think you lose too much sleep over this issue.

If he stopped worrying about his health so much his sleep would improve by biblical margin. 😉

Battery will run dry before he hits 117mph.

Probably by driving that? After couple decades in trucking I don't understand all that Cummins worshipping in some circles. Navistar, International, could be just as bad as Cummins, but there are better diesel manufacturers out there. I've seen catastrophic Cummins failures on trucks there were well maintained, and not abused. Probably shitty quality control, not necessarily insufficient design.

I just replaced coffee with green tea. I have small decaf in the morning, and couple cups of green tea at strategic intervals, like late morning and early afternoon. I've never had issues with falling in sleep, but if I woke up for whatever the reason early am, like 5am, it was game over. Would not sleep again. The problem got worse when I went back to much more stringent/ exhausting exercise routine. Like 140 pool lengths at 98 % of the throttle. I gotta admit, first couple of weeks after I went coffee free were simply brutal. Kinda a like someone hit you in the head with 2x4 in am, and that feeling would stay with you throughout the day. Much better now, I can sleep for 9hrs non stop no problemo, and my energy level don't have ups and downs like when I was coffee junkie. I do miss taste of great coffee, that's why I have small "cappuccino" decaf in am. Not much choices in decaf coffees thought, sad. 😭

That, and sugar. Casual glance at nutrition label shows insane amounts of "added sugar" at almost anytime. It almost makes me believe in some world wide conspiracy of sugar producers.

I'd like to expend on this. Ultra processed food once cooked tastes like shit next day, it is meant to be consumed right away. So, gotta cook it everyday. Surly cooking meals starting from fresh meat, poultry, fish, veggies, beans, etc. takes longer but even couple days later is still very tasty. So, you can cook every couple of days. When I do my time consuming burgers I cook greater quantities, I just freeze part of the batch. Still tastes excellent once defrosted. But I start with basics, fresh organic beef, etc. Try that with precooked burgers from supermarket. Defrosted once will taste like shit.

Headlights on my Volvo are on always. It does not hurt they go off when you lock the car. Don't have to think about it at all. Headlights always on apparently make my vehicle invisible to police radar. Never got pulled over in Volvo. Like ever. Cops just don't expect Volvo driver to brake any laws, so when they see 87 mph in 60 mph zone on their radar they just automatically dismiss it as equipment malfunction.

New here? Remember, simple rational solutions are last thing he wants to hear.

Because sometimes there is simply not enough room to use ratchet drivers. And forget T handle in tight spaces. Those cheap L shape Allens do the trick.

Yea, but if you fire injector only in the last part of the intake cycle fuel would not be distributed evenly, "front" of intake charge would not have any fuel at all. It eventually ends up in cylinder anyway but it would be an issue. I mean those secondary fuel injectors on the top of stacks are there to give enought time for fuel to vaporize. Early port fuel injection systems had batch fire, all injectors fired at the same time.

What? In port injection or carburetor engine fuel is mixed with air when it enters cylinder. So when injector fires is pretty much irrelevant. There is always some some fuel air mixture in intake tracks. Injector duty cycles on OEM tune is typically in 50-60 percent, not 25% if they were only firing on suction part of 4 stroke. 60% is over 200 degrees of crank rotation. It starts to fire way before intake valve opens. That 50-60 % gives time for fuel to vaporize. In DI it is awfully short, it has to wait till both valves are closed. In certain load/ rpm conditions some o it can get suck out straight to exhaust during overlap, right? I mean variable cam timing can help, but not eliminate. And, actually latest crop of bikes is forced to do without overlap, at least some of them, to clean emissions. How do you think you get all that nice popping when you close the throttle? Here. Point 4. https://www.cycleworld.com/story/blogs/ask-kevin/inline-four-sportbikes-and-euro-5-emissions/

Overall is cleaner because there is no risk of fresh charge, fuel, going into exhaust during overlap. And/or you can run more overlap. Allows higher CR ration because fuel has less time to heat up- less risk of detonation. 10+ CRs and 20 psi of boost are simply not possible on pump gas and port injection. On the other hand it has less time to vaporize, so less than perfect burn. Maybe they should run diesel level injection pressures of billions of psi.😁 As efficiently of combustion increase NOx goes up, difficult to bring it down without some sort of exhaust after treatment.

OEMs are happy. It is the same for everyone. I'll make killing selling parts once warranty is out.

They are talking 20-25 grand price increase for 2027 compliant class 8 tractor because of new emissions standards. Double DEF consumption, etc. Double the shit that will brake down. https://www.truckinginfo.com/10194891/epa-2027-and-beyond-how-will-new-low-nox-rules-affect-fleets

I'm pretty sure some EU models already have GPF.

Fargo.

Yep. Phone camera is blessing in situation like this. Not particularly related to this subject, but when doing more involved disassembly Ziploc bags and zip ties are very handy in organizing fasteners. Throw them in ziploc and attach with ziplock to whatever part you just pulled out. Huge time saver when putting shit back together. Especially if you doing it days or weeks later. Because, Bill Clinton voice, "my memory is not what it used to be". 😁 No precious time wasted trying to figure out what screw goes where, etc.

Oh, never mind.
