Carburetor Idle Jet #34 Mikuni 250cc CF250 CFmoto CN250 172MM B-600-1005-3101
$4.99 $4.99 Add to Cart

This is a Carburetor Idle Jet #34 for the CN250 CF250 GY6 250 172MM engine. These are pretty easy to replace and a must if you want to upgrade your engine's performance with performance parts or upgrades.

Mechanics Note: If you increase the size of your stock carb jet you will want to improve your air flow both in and out of the engine.  For smaller upgrades replace the stock air filter with a Performance Air Filter for this engine.  If you upgrade beyond small adjustments you will want to install a Performance Exhaust to handle the increased combustion and minimize back flow issues.

Altitude can play an issue in scooter performance. When you are dealing with elevation you will want to rejet to prevent your engine from siezing and requiring a rebuild.  You will loose about 3% in power for every 1000' in elevation. At 4000' feet you will have lost about 12% of your power output.  You will want to go down one (1) jet size for every 1750' to 2000' you go up in elevation.  When the air is colder it requires bigger jets because cold air is more dense. If it is 50 degrees colder you would increase your jet size at least one step up.  If you don't your engine can sieze on you.

When you are dealing with elevation you will want to rejet to prevent your engine from siezing and requiring a rebuild.  You will loose about 3% in power for every 1000' in elevation. At 4000' feet you will have lost about 12% of your power output.  You will want to go down one (1) jet size for every 1750' to 2000' you go up in elevation.  When the air is colder it requires bigger jets because cold air is more dense. If it is 50 degrees colder you would increase your jet size at least one step up.  If you don't your engine can sieze on you.
