    Help fixing bike please

    If it is shifting well, make sure to put the new spacers back in the way they came out. That BB can be used on a 68mm or 73mm wide frame. I think giant of that era was 68mm which required the spacer(s) be placed on the non-drive side like the original in your picture. If the original BB-52...

    2022 Mazda Miata Club RF Recaro

    Great work on his part...and yours. Our oldest is in first year engineering at the university of Calgary and paid for his first year with scholarships. He's taken to it like a fish to water and is getting very good grades. He's looking for an internship with one of the auto manufacturer...

    Modern Turbo Engine Reliability and Durability

    7 years on the TWIN turbo 3.5 in the truck. Regularly hauls itself and 8000lb trailer through the rockies (13500lbs or so). Makes travelling fun with how easily it pulls that weight.

    Help fixing bike please

    Maybe it's ISIS? Try this: I've pulled ISIS cranks with a long bolt through the center of the spindle and then tightening down on one side which pushes the splines out.

    Help fixing bike please

    That's a normal Shimano cartridge bottom bracket of the day. They came in different levels (BB-52, BB-72 ad BB-92) for LX, XT and XTR groupsets (now Deore, STX and XT, I think). the park tool BBT-9 or 19.2 will take that off once you have the cranks out. I've removed them with a pipe wrench...

    Francis Scott Key Bridge (Baltimore) hit by Cargo Ship and Collapsed

    As mentioned, extremely sad for those missing and their families. What does the US export to Sri Lanka? Was Baltimore just a stop along the way on this ship's route?

    Morals and working with the public

    None of what you described seems immoral to me. I needed a tie rod end last Saturday. Rockauto sells a Moog one for $18Cdn. I wanted to repair the car that day and went to NAPA to buy the NAPA (rebranded Moog here) and spent $48 for the same part. I paid for the convenience of getting the...

    Francis Scott Key Bridge (Baltimore) hit by Cargo Ship and Collapsed

    The way sections of the bridge on the opposite side of the OTHER support crashed down raises some design questions. I can see the center span dropping, but the whole thing turned into a teeter-totter. Scary engineering requirements.

    2021 MX-5 Miata 6MT Gear Lube

    I've tried Valvoline Syncromesh, Ford synthetic MTF and Redline MTL in the skyactiv 6spd before settling on the Amsoil fluid. Not sure if the miata has the same transmission. If you dig deep enough amsoil has yellow metal test information and it passes gl-4 without issue. I'm not an amsoil...

    Hyundai Tucson 1.6T Hybrid, engine damaged before first service is due

    I heard H/K management has their fingers in the engine manufacturing part of things and make money on the replacement engines as well so there is no incentive from the top to fix the problem. Not sure where I heard that so may be tinfoil hat fodder.

    Tesla fire closes down highway for 3 hours.

    A fire blanket can't smother a lithium fire. It has its own oxygen to keep the burn going. https://theloadstar.com/lithium-battery-fires-require-different-firefighting-techniques-says-safety-oem/

    Used Toyota Mirais, 90% depreciation (Hydrogen Fuel Cell Vehicle), ICE / BEV conversion candidate?

    Your observations are based on where you live. Central and Southern California works well for EVs, along with urban Europe. The rest of the world, far less so.

    Used Toyota Mirais, 90% depreciation (Hydrogen Fuel Cell Vehicle), ICE / BEV conversion candidate?

    I'll just leave this here. It's hard to make people who live in California (Silicone Valley even more so) understand the realities of weather/roads and the real world where EV's are no where near functional...

    My gen 1 3.5 Ecoboost; An inauspicious Start

    There is no EGR on a first gen eco. Crankcase vent to intake, but no EGR. It's a simulated EGR using some valve timing magic. https://www.motor.com/magazine-summary/dissecting-fords-ecoboost-engine/
