If you’ve ever tried to buy an ATV engine on Facebook Marketplace, you already know the problem: it’s not the engine that’s risky — it’s the guesswork. Vague listings. “Ran when parked.” Ghosting. Scammers. And zero accountability.
This checklist helps you buy smarter anywhere, but it’s built for ISO Powersports Parts — a safer alternative to Facebook Marketplace where sellers have built-in accountability, and repeat sellers have a real reason to be accurate and responsive.

The 60-Second “Should I Buy This?” Check
Before you send money, make sure you can say YES to these:
- Fitment is confirmed for my exact ATV (make/model/year/trim)
- I have proof it runs (cold-start video is best)
- I have compression numbers (leakdown is a bonus)
- I know what’s included (and what’s not)
- The seller has accountability (ratings/reputation + clear policies)
- Shipping is insured and packaged correctly
- https://www.isopowersportsparts.com/general/shipping
- The total cost still makes sense after the “extras”
On ISO, the big win is simple: you’re not buying from a random profile — you’re buying from a seller with a track record.
Step 1: Know What You Need (So You Don’t Buy “Close Enough”)
Before you shop, grab:
- Your ATV make / model / year / trim
- Engine size (cc) and any engine code (if available)
- Carb or EFI
- Air-cooled or liquid-cooled
- Manual / auto / CVT (as applicable)
- What you’re reusing vs replacing (ECU/CDI, throttle body/carb, stator, starter, wiring)
Step 2: The Used ATV Engine Checklist (What to Ask + What to Look For)
1) Fitment (The Dealbreaker)
Ask:
- “What ATV did this come off of? Make/model/year?”
- “Can you confirm it fits a [your exact make/model/year]?”
- “Any part numbers on the cases/head you can share?”

2) Proof It Runs (Evidence > Stories)
Request:
- Cold-start video (cold engine, start-up, idle)
- Idle + throttle blip video (listen for knock/tick)
- Compression test numbers (and how they tested it)
- Photos of all sides + close-ups of mounts, threads, connectors
3) Red Flags (The “Nope” List)
Walk away if you see:
- Cracked cases or patchwork repairs (epoxy/JB weld)
- Broken mounts or heavy impact marks
- Stripped bolt holes everywhere
- Milky oil, burnt smell, sludge, or metal flakes
- Heavy corrosion (especially on liquid-cooled engines)
4) What’s Included (Because “Complete” Usually Isn’t)
Ask:
- “Is this a long block or a complete engine?”
- “What’s included — stator, starter, clutch, sensors, throttle body/carb?”
5) Seller Trust (This Is the Whole Point)
If you’re buying on Facebook, you’re basically trusting a profile picture.
If you’re buying on ISO, look for:
- A seller with ratings/reputation
- Consistent listing quality and responsiveness
- Clear expectations and fewer “disappearing acts”
If anything feels off, keep shopping:

6) Shipping (Protect Your Money)
Require:
- Proper packaging (palletized freight is ideal)
- Fluids drained; ports capped; shafts protected
- Insurance + tracking + signature
- Inspect on delivery and take photos before signing if there’s damage
