Hey RedBrick, I was just swapping an old chain on a ’70s Harley and remembered how much you love a good revamp. Got any tips for keeping that classic engine running smooth?

Sure thing. First, keep the oil level in check – change it every 1,000 miles or so, even if the gauge says “good.” Then, make sure the air filter’s clean; a clogged filter is like a block in a pipe. Tighten the valve clearance every 3,000 miles – you’ll feel it if the engine rattles a bit. Don’t forget to keep the carb mix right; a little extra fuel in the old days was good for it. Finally, give the spark plugs a quick look; a worn plug can throw the whole thing off. That’s it, and you’ll have that old Harley running smooth for years.

Sounds good, RedBrick. Just keep an eye on that carburetor—those old engines can be picky. Got any part you’re tripping over right now?

Yeah, I’m still wrestling with those flywheel bolts on the big iron. They’re stubborn, and the old bolt heads are warped. I keep slipping on them and it’s a pain. Got any tips on getting a good grip?

Give the bolts a good soak in penetrating oil, let it sit a bit, then grab a heavy‑duty strap wrench or a socket with a rubber pad on it. If the head’s warped, tap it lightly with a hammer and a punch to straighten it before you tighten. Don’t try to force it—keep the torque steady and use a breaker bar for extra leverage. Once the head’s straight, a new head or a replacement bolt works the best. And if you’re still slipping, swap the old head for a new one that fits the socket snug. That’ll keep you from turning the whole frame.

Got it, thanks. I’ll give that a go and see if it helps. Appreciate the solid advice.
