When your quad starts knocking, leaking, or just plain lagging, you’re stuck with the age-old gearhead question: Do I fix it, or do I toss it and upgrade?
Whether you’re riding a Yamaha Banshee, Blaster, Raptor, or something a little more custom, there are some key parts that’ll make or break your ride.
Here’s how to know when to rebuild and when it’s time to move on.
1. Crankshaft: Rebuild or Replace?
When to repair:
- Minor scoring or pitting can sometimes be polished out.
- If the rods are straight and the journals are within spec, you can press in new bearings and keep rolling.
When to replace:
- If the crank is bent or out of true, don’t gamble. Replace it.
-
Wobbling crank = catastrophic engine failure waiting to happen.
Pro tip: Always check crank seals and bearings while you're in there. No point doing half a job.
2. Pistons and Rings: The Wear-and-Tear Champs
Pistons take a beating — especially if you’re pushing limits on trails or dunes. Detonation, overheating, and lean mixtures can all torch your top end fast.
When to repair:
- Light wear? A new set of rings and a hone job might bring it back.
-
Good compression and no scoring? You’re probably good with a top-end refresh.
When to replace:
- Deep scoring, cracked skirts, or blow-by signs = full piston replacement.
-
Going bigger? Now’s your time to bore out that cylinder and jump up a size.
3. Clutch: Grip or Slip?
If your throttle's screaming but the wheels aren't digging, you’ve got a slipping clutch. Mud, heat, and age all play a part.
When to repair:
- Worn friction plates or springs? Replace just those parts.
-
Good for keeping costs down, especially if your basket and hub are solid.
When to replace:
- Grooved clutch basket fingers = time to replace.
- Warped steels or a burnt smell? Toss the whole setup.
Upgrading to a heavy-duty clutch is a smart move for aggressive riders who like to keep RPMs screaming.
4. Suspension Components: Smooth or Shook?
When to repair:
- Leaking shocks? Rebuild kits exist—if you’ve got the tools and skills.
-
Bushing and bearing replacements can save your front-end geometry without breaking the bank.
When to replace:
- Bent A-arms or cracked welds? Don’t even think about riding on that.
-
Upgrading to long-travel arms or beefier shocks? You’ll feel it in every corner and jump.
5. Electricals: Sparks or Silence?
Wiring issues and failed ignition parts can drive you nuts. CDI boxes, stators, coils — all crucial to firing up.
When to repair:
- Loose connections or corroded grounds? Clean and tighten ‘em.
-
Shorted wires? Splice in some new leads and heat-shrink wrap it.
When to replace:
- Dead stator? Burnt-out CDI? Swap them fast before you chase ghosts for hours.
-
Voltage regulator going out? Replace it before you fry the battery or lights.
