Motorcycle & Powersports Fuel Injector Cleaning

Ultrasonic cleaning and flow testing for bikes, ATVs, UTVs, snowmobiles, and personal watercraft.

Powersports injectors clog for the same reasons automotive injectors do: carbon buildup, fuel degradation, and ethanol deposits. But there's a key difference: powersports vehicles sit. A lot. Winter storage, off-season downtime, that project bike in the garage. And when fuel sits in small injectors for months, deposits form fast.

The other problem is finding someone to clean them. Most motorcycle shops and ATV dealers don't have a flow bench. They'll either suggest new injectors at $80-150+ each or tell you to run some fuel additive through it. Neither option gives you actual data on what your injectors are doing.

We clean and flow test motorcycle and powersports injectors the same way we handle automotive: ultrasonic cleaning, backflushing, and individual flow testing with a full performance report. Ship them in, get them back in a few days.

Why Powersports Injectors Clog

Seasonal Storage

This is the #1 cause. Motorcycles, snowmobiles, ATVs, and jet skis all spend months sitting with fuel in the system. Gasoline starts to degrade after about 30 days, and ethanol-blended fuel degrades faster. The deposits it leaves behind collect inside the injector nozzle where fuel additives can't reach them.

Small Orifice Size

Powersports injectors are often smaller than automotive injectors. A motorcycle injector might flow 80-120 cc/min compared to 200-300+ on a car. That smaller orifice means even a tiny amount of buildup represents a bigger percentage of restriction. A deposit that barely affects a car injector can choke a motorcycle injector.

Ethanol Fuel

E10 gasoline absorbs moisture from the air. In a sealed automotive fuel system, this is manageable. In a vented motorcycle tank or ATV fuel system, moisture absorption is worse. That moisture accelerates corrosion and deposit formation inside the injectors. Stabilizer helps but doesn't eliminate the problem over long storage periods.

Signs Your Powersports Injectors Need Cleaning

  • Rough or unstable idle
  • Stumbling on deceleration or off-throttle
  • Poor cold start, extended cranking, or won't start without choke
  • Hesitation or flat spot when rolling on throttle
  • Running lean at certain RPMs (popping on decel is a classic sign)
  • Inconsistent throttle response compared to when the bike ran well
  • Reduced fuel economy
  • Bike sat for 6+ months with fuel in it

How It Works

01

Remove Your Injectors

On most bikes, injectors are accessible by removing the fuel tank and airbox. If you're not comfortable doing it, any motorcycle shop can pull them in under an hour.

02

Ship Them to Us

Fill out the order form, use the prepaid shipping label, and drop them at USPS. Motorcycle injectors are small, so a set of 4 fits in a small flat-rate box easily.

03

We Clean & Test

Ultrasonic cleaning, backflushing, and individual flow testing. Each injector gets tested separately so you know exactly what each one is doing.

04

Reinstall & Ride

We ship them back with new O-rings and a full performance report. Most orders are turned around in 1-3 business days.

Frequently Asked Questions

Can motorcycle fuel injectors be cleaned?
Yes. Motorcycle fuel injectors are cleaned the same way as automotive injectors: ultrasonic cleaning followed by individual flow testing. The smaller orifice size on many motorcycle injectors actually makes cleaning more important, since even minor deposits can cause a noticeable change in performance.
How much does motorcycle fuel injector cleaning cost?
Motorcycle and powersports injector cleaning is $35 per injector. A flat $35 shipping and insurance fee covers prepaid insured shipping both ways. A 4-injector minimum service charge applies even if you're sending fewer. For a typical 4-cylinder sport bike, that's $175 total including shipping.
Why don't local shops clean motorcycle injectors?
Most motorcycle shops and general mechanics don't own fuel injector flow testing equipment. It's specialized gear that doesn't make financial sense unless injector cleaning is a core part of the business. That's why mail-in cleaning services exist. You send the injectors, we clean and test them on professional equipment, and ship them back.
How do I know if my motorcycle injectors need cleaning?
Common signs include rough idle, stumbling on deceleration, poor cold start behavior, inconsistent throttle response, reduced fuel economy, and the bike running lean at certain RPMs. If your bike has been sitting for an extended period (winter storage, barn find, etc.), the injectors are almost certainly partially clogged from fuel degradation.
