Motorcycle Repair That Actually Gets Finished

Most auto shops turn motorcycles away. Hamiltons Automotive on First Street in Novato doesn't. We handle motorcycle repair alongside cars, trucks, and golf carts, and we treat every bike with the same diagnostic rigor we bring to a full-size vehicle. If your bike won't start, is running rough, or has a warning light you've been ignoring, call us at 415-898-4842 and let's figure out what it needs.

Motorcycle repair costs vary widely depending on what's wrong. A brake job lands in a very different place than an engine rebuild or electrical fault diagnosis, the gap between a simple fix and a major overhaul is real, and anyone quoting you a flat number before they've looked at the bike is guessing. What we do: inspect it, tell you exactly what we found, explain your options, and let you decide. Every job is different, contact Hamiltons Automotive INC for an accurate estimate. We've earned 4.7 stars across 111 Google reviews by being straight with people, and that doesn't change when it's a motorcycle on the lift.

What We Cover

Motorcycle Services at Hamiltons Motorcycle Services

From routine maintenance to hard-to-diagnose electrical faults, we handle it in-house.

01

Engine Diagnostics and Repair

Rough idle, misfires, loss of power, warning lights, we run a full diagnostic before we wrench anything. Guessing costs you money. We scan first, confirm the fault, then fix the actual cause.

02

Brake Inspection and Service

Brake fade or a spongy lever on a motorcycle isn't an inconvenience. It's a safety issue. We inspect pads, rotors, calipers, and hydraulic lines and replace what's worn, not what looks easy.

03

Electrical Fault Diagnosis

Charging system problems, dead batteries, blown fuses, and wiring gremlins are some of the trickiest repairs on any bike. We track the fault to the source instead of throwing parts at it.

04

Carburetor and Fuel System

Clogged jets, float valves, and fuel delivery issues are common on bikes that sit for a season. We clean, rebuild, or replace as needed, and we'll tell you which option actually makes sense for your bike.

05

Suspension and Steering

Handling that feels vague or a front end that dives too hard under braking points to suspension wear. We inspect forks, linkages, and bearings as part of any handling complaint, not as an afterthought.

06

Routine Maintenance

Oil changes, chain adjustments, air filters, spark plugs, and valve clearances. Skipping these doesn't save money, it shortens engine life and creates the expensive problems people try to avoid.

Our Process

How We Handle Motorcycle Repairs

  1. 01

    Inspect and Diagnose

    We put the bike on the lift and look at it properly, not a quick visual pass. Diagnostic scan if the bike supports it, plus a mechanical inspection of the systems related to your complaint.

  2. 02

    Explain Before We Touch Anything

    You get a clear rundown of what we found and what fixing it involves. No surprise charges, no work done without your approval. If there's more than one way to handle it, we'll tell you that too.

  3. 03

    Fix It and Verify

    We complete the repair and check the work before the bike leaves. If something else comes up during the job that affects safety, we flag it. We don't ignore it and hope you don't notice.

Why Hamiltons

What Makes This Shop Different for Motorcycle Work

Most shops in Marin County that touch motorcycles are specialists who won't look at your car, or general auto shops that quietly send bikes elsewhere. We're neither.

Signs Your Motorcycle Needs a Mechanic Now

Don't wait until a minor issue becomes a stranded-on-the-highway problem.

  1. 01

    Hard starting or won't start at all

    Could be fuel, ignition, or a dead battery, but it could also be a compression problem. Get it checked before you're stuck.

  2. 02

    Brake lever feels soft or pulls too far

    Air in the hydraulic line or worn pads. Either way, this is a safety fault, not a 'fix it later' situation.

  3. 03

    Oil leak or burning smell after riding

    A small leak that hits hot exhaust components is a fire risk. Don't ride a leaking bike until the source is identified.

  4. 04

    Handling feels unstable at speed

    Tire pressure, wheel bearing wear, or fork oil degradation can all cause this. Any of them can be dangerous, only one of them is cheap to fix. You need to know which one it is.

Bay Area Motorcycle Riders We Work With

Frequently asked questions

How much does motorcycle repair cost?
Cost depends almost entirely on what's wrong. A carburetor clean or brake fluid flush is a fraction of what an engine rebuild or electrical fault diagnosis runs. Labor time, parts availability, and the bike's age and condition all move the number. We inspect the bike first, give you a clear breakdown, and you decide how to proceed. Every job is different, contact Hamiltons Automotive INC for an accurate estimate.
What do you call a person who fixes motorcycles?
Motorcycle mechanic is the standard term, though many shops use 'powersports technician' for someone trained across bikes, ATVs, and similar vehicles. At Hamiltons, the same team that handles car and truck repairs works on motorcycles. It's not a separate specialist department. We've got the diagnostic equipment and the hands-on experience to handle most motorcycle repair work that comes through the door.
Can you run a diagnostic scan on my motorcycle?
For modern bikes with an OBD port or proprietary diagnostic connector, yes. Older carbureted bikes don't have a scan port, so diagnosis is mechanical, compression test, fuel delivery check, ignition timing, that sort of thing. Either way, we diagnose before we repair. A fault code tells you where to start looking; it doesn't always tell you what actually failed. We interpret the data, not just read it off a screen.
Do you work on both Japanese and American motorcycles?
Yes. We see Hondas, Yamahas, Kawasakis, Suzukis, and Harleys regularly. The mechanical fundamentals are similar; the parts sourcing and some specifications differ. If you've got a less common make or a vintage bike, call us first at 415-898-4842 and we'll tell you upfront whether it's something we're set up to handle, no wasted trip.
My motorcycle has been sitting for months. What should I checked before riding it?
Fuel system first, stale gas and varnished carb jets are the most common sit-related failures. Then brakes: rubber seals in calipers and master cylinders degrade when the bike isn't used. Tires lose pressure and can develop flat spots. Battery state is usually obvious but people overlook chain tension and lubrication after a long sit. Bring it in and we'll go through it systematically rather than guessing what's okay.
How long does a typical motorcycle repair take at your shop?
Straightforward maintenance, oil change, brake pads, chain service, usually wraps same day. Electrical faults and engine work take longer because diagnosis is the hard part. We don't guess and swap parts hoping one works. Once we know what's wrong we can give you a realistic timeline. Call us at 415-898-4842 and describe what the bike is doing. We can often give you a rough idea before you even bring it in.
