Paramotor Service & Assembly Information
1. Basics
A. Troubleshooting paramotors – Solve most problems with your paramotor. Having us or another competent mechanic service your engine can be *VERY EXPENSIVE*. Learn to do it yourself. All paramotors are the equivalent of motorcycle racing engines and must be serviced with the utmost care – and why this website exists.
B. Engine break-in procedures – All new or rebuilt engines must be broken in. If this is not done, the engine will have a much shorter life.
C. Paramotor essential tool kit – here are the tools from Harbor Freight (USA) and others that you need to work on your paramotor.
D. Paramotor assembly guide and accompanying video This video is for the Miniplane Thor 130, others similar.
E. Shipping a complete paramotor for travel – How to properly pack and ship a complete paramotor (including the frame and harness). These instructions are *not* for shipping a paramotor to Southwest Airsports for repair.
2. Paramotor info by make and model
Check the links below for helpful information on taking care of your paramotor. Many of the issues with the Polini, Minari, Simonini, and other engines are common to the Top 80 so be sure to check the Top 80 section if you cannot find what you are looking for.
General – Info common to most paramotors including torque values, electrical & ignition systems, etc.
Carburetors WG-8 WB-37 Polini carburetor (two stroke carburetors all leak/drip – some more, some less)
Polini Thor all models General info on the Thor models (for manuals, see the links below)
Vittorazi Moster 185 – Owners manual Servicing, troubleshooting, and repairing this engine is very similar to the Minari. See all the General info page. Miniplane-USA has the parts. Electrical and ignition troubleshooting. Electric starter specs – 40 to 45 Amps, rarely 50 Amps. When the engine can spin freely it should be around 21 Amps.
Every 50 hours if AVGAS is used
- Clean out the decompression port (DCP). Failure to clean this will result in greatly increased effort needed to start the engine and will cause premature wear of the starter. If unleaded fuel is used, this maintenance may be done every 100 hrs.
- Remove carbon and/or lead deposits from the top of piston and cylinder head. Use a razor blade for the piston and a Dremel steel wire brush on the cylinder head. Failure to routinely remove deposits will increase compression, combustion temperatures, and will shorten engine life. If unleaded fuel is used, this maintenance may be done every 100 hrs.
