01 Scheduled service
RE interval service: engine oil and filter, fluids, brake check, chain and fasteners, plus valve/tappet clearance when the schedule calls for it.
Independent Royal Enfield workshop for the 350 and 450 singles, the 650 twins and the classic Bullets. Diagnostics, scheduled service, valve and tappet work, custom builds and restoration — by a team with a genuine engineering pedigree.
Iron Custom Motors is an independent Royal Enfield workshop in São Domingos de Rana, Cascais. We service the full modern line-up — the J-platform 350 singles, the liquid-cooled 450s, the 648 parallel twins — and we welcome the classics: UCE and pre-unit Bullets, Continental GTs, the older 500s.
Royal Enfield is the oldest motorcycle brand in continuous production, and the people who ride them know exactly why. These bikes are about character, mechanical honesty and a riding experience that doesn't need to be loud to be felt. Our job is to respect that — to keep the bike doing what it was built to do, not to fight its nature with over-complication.
The engineering culture behind the workshop is the same one that earned ICM the AMD World Champions title, a Bonneville land-speed record and the BMW Motorrad Customizing Championship 2023. We bring that standard to a Classic 350 as readily as to a competition build. And because Royal Enfield is one of the most popular custom base bikes in the world — bobbers, scramblers, café racers — there is no shop better placed to turn yours into something personal. See our custom & special projects.
Independent means no dealer mark-up, the freedom to fit OEM or quality aftermarket parts as the job actually requires, and straight talk. Written estimate before the work, written report after.
The modern Royal Enfield range is fuel-injected — the J-platform 350s and the 648 twins run EFI with an ECU. The classics run carburettors. We are set up for both, which most general workshops are not.
We read and clear RE-specific ECU fault codes, monitor live sensor data, check fuelling and run the resets the bike needs after service.
Throttle-body cleaning and balance, idle and fuelling checks on the 350 and 650 EFI engines — done to the figures, not by feel.
Proper bench work, jet selection and synchronisation for UCE and earlier Bullets, Continental GT 535 and the older 500s.
Feeler gauges, the correct shims and tappet hardware, and the patience these engines reward. Valve and tappet clearance is central to RE ownership and we treat it that way.
From a first scheduled service on a new Hunter 350 to a ground-up Bullet restoration — all of it with Royal Enfield knowledge and the right tools.
RE interval service: engine oil and filter, fluids, brake check, chain and fasteners, plus valve/tappet clearance when the schedule calls for it.
Done properly with feeler gauges and correct shims. Central to RE health on both the singles and the 650 twins — neglected, it costs you smoothness, economy and eventually the head.
Regulator-rectifier and charging-system checks on higher-mileage bikes, battery, lighting and accessory wiring. We chase the cause, not the symptom.
Carb rebuilds and synchronisation on the classics; EFI cleaning, balance and fuelling checks on the modern 350 and 650.
Fork seals and oil, rear shock service, sag setup, wheel bearings and tyres. While the wheels are out, our tyre fitting and balancing service sorts new rubber properly in the same visit.
The older Bullets and UCE engines are known for oil seepage. We don't chase it with sealant — we find the source, replace seals and gaskets properly and set it right.
Clean, lube and adjust; sprocket inspection and replacement. The cheapest preventive job there is, and one vibration loves to undo over time — so we re-torque the right fasteners too.
Bobbers, scramblers and café racers built from your RE; full restoration of a Bullet from tired to right. See upgrades & tuning and custom.
We know Royal Enfields, so we check the right items proactively rather than waiting for them to strand you.
Central to every RE. We measure and adjust to spec — the difference between a sweet engine and a rough, thirsty one.
A known trait of older Bullets and UCE engines. We trace the real source and seal it properly, not cosmetically.
Higher-mileage symptoms — weak charge, flat batteries. We read the charging system fully before condemning a part.
RE character includes vibration; over time it backs off bolts. We re-torque the points that matter at every service.
Neglected chains chew sprockets and cost many times the price of regular care. We catch it early.
The early Himalayan had teething issues, addressed over the years. We know the points to check on these.
Current production, recent past and the classics — if it wears the gun-on-the-tank or the Royal Enfield script, bring it in.
Classic 350, Bullet 350, Meteor 350, Hunter 350, Goan Classic 350.
