No matter where Ari goes, he makes me feel like I don’t care for my chain enough.

I worked at Suzuki dealership and a guy got his girlfriend to buy him a brand new GSX-R 600. He did a diy license plate delete and relocated it in front of the rear tire. He should have checked to see what he was screwing into with his drywall screws. Right through the ECU and into the battery. One of my favorite things that happened working in that shop.

I don't think Ari has ever had any formal mechanics training but damn he knows his stuff. Watched him for years both breaking down stuff for us simpletons and doing amazing improvised roadside repairs. Such a great contributor to the motorcycling community.

Im surprised that sandro wasnt in this as an expert he literally does everything

I've had a customer bring their motorcycle into the shop complaining that his bike just quit, turned out it was out of gas. Another customer was proud of himself that he spent all winter putting braided stainless on his entire wiring harness but did nothing about the tiny sharp stainless wires poking into the harness. His complaint was every time he honked the horn his bike quit (he's lucky that's all that happened)

Bring Ari more often and do more motorcycle vids.

The R1 with the disintegrated air filter, that was a BMC brand filter. I see it often with that brand. The plastic they use around the outer frame of the filter does NOT hold up to heat long. This happens after the filter gets more than a couple years old. And Ari is 100% correct about checking the tank A, #1, first thing.

Ari is a legend. Always learn when he’s around.

Seeing Ari’s face light up at 6:21 made my day. Great video, thanks guys!

I love Ari!. It’s always fun to watch him fix things on those big trips.

My mother has an old Kawasaki motorcycle that's been sitting derelict for well over 30 years at this point. When I was a kid she wanted to fix it and both me and my older sibling at various points in our lives thought of maybe trying to fix it with the intent of learning to ride. These videos have reminded me that that would be an undertaking requiring far more effort and expense than we could probably handle.

I really like hearing Ari talk about bikes, lots of knowledge and no bs!

8:30 you arent wrong about maintenance! Not quite the same thing but the surface grinder at my old work my boss had been filling with 5w30, instead of proper machine oil. When the chain-traverse finally gave up the ghost the sprocket was essentially the shape of a blunt circular saw


Edit: per your point around 15:30 - you are indeed unfortunately correct, this was how I lost my best friend in 2019. Chain snapped and bunch of knock-on effects took him off.

RIP Matt ❤ never forgotten brother

I'm loving Ari. I don't ride motorcycles. I always wanted to. I'm a car guy, for sure, but I love and respect bikes and bikers. Ari's outlook, attitude, reactions, etc... is awesome! I'll be looking up Revzilla next

I've had a similar screw get stuck in between my swing arm assembly and the engine casing and it actually pushed a hole through my engine compartment and dumped the oil under the rear wheel. Fun times

Two of my favorite YouTubers in the same video! I thought it would never happen! Fire it up!

It's good to see Jer doing bike stuff. You can tell it makes him happy!

[ericmoney]

I used to build drag carts, and against the advice of everyone, dude in the shop decided he needed to take his engine for a run **now**. Skipped installing a chain guard, put in a used master link, on a cart running about 12hp engine with a triple disk bully. That link snapped and slapped that chain into his arm almost to the bone. Wrapped around his bicep like a whip.

Chains. Are. Dangerous.
