GoFaster Engines Tier List

Engine choice decides whether your GoFaster bike screams down the map or overheats after one pull. This list ranks engine families and swap targets for Version 0.3 [BETA], where reed valves, ignition, temperature, and durability all matter.

S-tier engines

Tuned AM6 / inline-2 packs

The inline-2 AM6 pack added in 0.3 is the current prestige route for players who already understand workbench snapping. Pair it with updated reed valves and a matching exhaust tip. High ceiling, higher parts cost, and less forgiveness if temperature spikes.

Why S: Strong power band in creator showcases, future-proof for more AM6 content, excellent when ignition and reeds are installed correctly.

Fully rebuilt performance 2-stroke

A carefully assembled performance 2-stroke with fresh piston rings, correct crank alignment, and deep 2T sound tuning still competes when you cannot afford a full AM6 kit yet.

Why S: Best speed-per-dollar once you know the build order.

A-tier engines

Yamaha-style 50cc platforms

Popular in community clips for approachable sound and handling. Great mid-game engine when you upgrade reeds and exhaust together.

Honda-style AM6 starter packs

Not every AM6 drop is equal — unfinished texture packs still run, but expect more frequent rebuilds until models mature. Rank A until durability settles.

Balanced street / dirt hybrids

Engines that keep temperature stable on mixed grass and asphalt after the slippery-grass fix. Slightly lower peak speed, fewer blown runs.

B-tier engines

Stock dealership mills

Fine for learning kickstart, clutch feel, and scroll camera controls. Replace once you finish Getting Started.

Untuned 80cc experiments

Double-motor and oversized 80cc experiments look wild on TikTok but punish mistakes. Park them in B until you master cooling discipline.

Cosmetic-first show engines

Built for sound and looks. Fun for clips, mid for serious grinding.

C-tier engines

Broken salvage blocks

Useful only as a temporary swap target while you gather cases, crank, piston, and head. Do not race them.

Mismatched frankenstein stacks

Random parts from different families that refuse to seat cleanly on the workbench. Time sink.

D-tier engines

Neglected overheating builds

Any engine run without watching the new speedometer temperature functions. Durability loss turns expensive parts into scrap.

Install tips that change tier results

1. Follow case → transmission → crank → second case → ignition → piston → rings → head → valve cover → intake → reeds.
2. Use the remastered ignition; old mounts fight the 0.3 system.
3. Attach exhaust at the correct angle — see customize bike.
4. Kickstart with the animated starter; do not spam inputs.
5. Recheck part durability after long sessions.

Sample progressive path

1. Buy used bike with starter cash.
2. Rebuild stock engine to B/A stability.
3. Farm cash via make money.
4. Move into Yamaha-style 50cc or early AM6.
5. Finish with tuned inline-2 AM6 + reeds + premium exhaust.

That path beats jumping straight to a viral S-tier clip build with empty pockets.

Heat discipline by tier

S-tier packs punish red gauges hardest because replacement parts cost more. A-tier hybrids forgive one mistake. B-tier stock mills are your practice heaters. Whatever you ride, glance at the speedometer temperature functions before another pull — tier letters do not save an ignored durability bar.
