I tested how far a Harley Evo would run without oil for 20-30 minutes. Not a quick blip. Twenty to thirty minutes into a ride before it finally seized up from the heat.

It still started up again right after it died. Obviously didn’t go far from there though.

That’s an Evolution motor. You can blow the top end, tear the whole thing down, put it back together with fresh parts and be running the next day. As long as you didn’t destroy the case it’s basically bulletproof. Most engines would’ve been a paperweight after the first five minutes without oil, but they finally built something that lasts with this one.

Not recommending you try it. I already did that part for you. But if you’ve got the time and money you could test it out 😂

Gotta get em done so I can keep building bikes and riding.

Honestly you’re probably flooding your bike. But luckily the solution is really simple.

When a kickstart won’t fire, most guys will give it extra squirts of fuel thinking more gas will get it to start easier. It’s the opposite most of the time. Too much fuel means the plugs are wet, and wet plugs won’t spark. You need v***r to ignite, not liquid sitting on everything.

How do you clear it? Glad you asked. Hold the throttle wide open and kick it through a few times, or hit the electric start and let it cycle. Wide open throttle means the carb isn’t pulling fuel, so you’re essentially blowing the plugs dry until she wants to fire again. Once it does catch it’s probably going to backfire first and scare everyone in a three garage radius.

We all gotta learn it eventually. Hopefully you can learn from me and not from personal experience 🤣

You thought you’d actually get that build done in a weekend? 🤣

Hot humid day and your bike feels sluggish? It probably is.

That’s not in your head, you can lose up to 12% of your power on a day like that.

Best way to think about it: go outside right now and sprint to the end of your street.
How do you feel? That’s exactly what your motor is doing on a hot, humid, low oxygen day. Now do that same run on a cool, dry, high oxygen day and you’ll feel like you’re just getting warmed up at the end of the block. Your engine is no different.

And just so yah know, cold doesn’t automatically mean good either. Motors want high oxygen content, low humidity. Cool and damp is still a bad day. That perfect fall morning with no humidity is what your bike actually wants.

Next time it feels off, check the weather before you check the bike.

Fuel injection destroyed control..

That’s the whole carb vs EFI debate right there. With a carburetor you pull a jet, swap a needle, throw a spacer in, and you know exactly what you changed and why. Something’s off, you fix it on the spot. With fuel injection you’re hooking it to a computer and hoping the machine reads it right. Maybe it does, maybe it doesn’t.

Some guys love that. We’re not those guys.

Carb or EFI where do you stand? Drop it below.

Mechanics learn this first..

One of the best things you can learn is how to listen to the motorcycle. That’s not just a saying. Larry was doing a dyno tune and could hear the motor running flat from the jump, then around 4,000 RPMs the fuel started coming in closer to where it wanted to be and the whole thing changed. The computer gives you numbers. Experience tells you what the computer could be missing.

Same thing when you’re seating rings on a fresh engine build. You don’t need a dyno for that. Lug it in a high gear and listen. When the rings seat you’ll hear it instantly. It gets louder, starts popping, and if you’ve done it enough times you know.

That’s the things they don’t teach in school.

Check out this full video on YouTube. Larry’s got a lot of gems.

Do you know how often to service your forks?

Well, Harley recommends servicing your forks once a year. That means new seals, new fluid, the whole thing. Most guys have haven’t touched theirs since they bought the bike.

Draining them is easy. There’s a Phillips screw on the back of each fork leg, pull it and let them drain out.
Here’s the part people mess up on the refill: every front end has a dry measurement and a wet measurement on the spec sheet. Dry is for a brand new, never assembled fork. Wet is what you’re working with. If it says dry at 13 and wet at 11, you’re putting in 11 ounces of fork oil. And whatever amount you put in one side goes in the other, same amount, both forks, no exceptions. One side stiffer than the other means your front end is going to do a little dance down the road and nobody wants that.

Save this one. It’s a once a year job that most people skip entirely

What’s gonna put you and your bike on the ground just as fast as low pressure will?

Dry rotted and cracked tires. When you only got two tires don’t risk it. If your tire looks like it’s been sitting in the desert for ten years, replace it you’re literally putting your life on a rubber compound that’s already failing.

On the cheap tire debate: yeah a Shinko is going to cost you less today. But in 3,000-5,000 miles you’re back buying another one.

A Michelin, Dunlop, Pirelli, or Metzeler will sometimes go double or triple that. Do the math over a full year of riding and the cheap tire almost always costs you more. Buy the better tire once, or buy the cheap one three times. Your call.

Good tires will run you $300-$500. I don’t know what your life is worth to you but I know it’s more than that.
Check your tires before every season. If you see cracking, don’t talk yourself out of replacing it.
