Most likely cause
BasicOil dripping onto the exhaust
A small oil leak dripping onto the hot header or muffler produces a burning smell and sometimes a wisp of smoke. It's often the most mundane cause. Clean the exhaust, identify and fix the leak (retightening, gasket, correct level) and the smell disappears. 🟢 Simple visual diagnosis. This tool helps you understand what's going on -- it doesn't replace a certified mechanic.
How to make the repair yourself
🟢 Within reach of any rider: no advanced mechanical skill or specialised tooling needed.
- Engine cold, look for greasy traces on the header/muffler and trace back up to the source (sump plug, valve cover, dipstick, filter).
- Check the oil level: an overfill can push back and leak.
- Fix the leak: retighten to torque, replace the gasket concerned (valve cover, plug), refit the dipstick/plug correctly.
- Clean the exhaust thoroughly (residual oil keeps smoking for a while).
- Run the engine and check the smell and the drops are gone.

If in persistent doubt, if a safety-critical part is involved (braking, steering, bearings, transmission), or if the problem keeps recurring, have the diagnosis confirmed at a workshop before doing any work.
