20 Most Recent 2011 PGO PMX Naked 50 Questions & Answers

An engine, in order to start, needs a good cranking speed, good compression, the right amount of fuel inside the cylinder at the right time and a good spark at the right time.
An engine that doesn't start has one of those things missing and it is pointless guessing which.

The spark plug is probably the easiest to check to begin but it is folly to replace it without checking the spark as part of the process.

motors need three things to run. Fuel, Oxygen, and Ignition (spark).
If you leave motorcycles set for a long time, the gas in the carburetor will turn to lacquer. If that is the case no fuel will get to the spark plug. Spraying starting fluid in the air cleaner or carb can prove this, and it will start and run for a couple seconds then die.
If you can smell gas, you have either no spark or it may be flooded. If you don't have spark, find out if there is a blown fuse, or a shorted wire.

If it is a wasted spark coil then it depends on whether electronic ignition or points based.

Hi there I have a lexmoto venom 125cc and I have no power at all the battery and the main fuse are fine is there any other fuse box?

Motorcycles | Answered on Jan 11, 2021

It could because of a fault with almost anything except the spark plugs.

The handbook should tell you what circuits are protected by that fuse, often a single fuse protects a few circuits and it can be difficult to discover which has the fault - in some cases it can mean considerable dismantling and disconnecting of wires to find the fault.
Intermittent faults are the worst and it can take a long time to discover a pattern to when the fuse fails and in this case it can save time and trouble to fit a suitable micro circuit breaker in place of the fuse.
