Main Jets, for Keihin Carburetor

Carburetor Main Jets
LIST PRICE: $7.95
HOLIDAY SALE: $3.95
IN STOCK
MFG: Keihin
MFG Number: G-Keihin Jets

PRODUCT OPTIONS

Kehin Carburetor Jets
Hex Head Main Jets
for Keihin Carburetors 24 to 32mm.
 
Almost all Buggies and Scooters with a GY6150 or CN250 engine will use these jets
 
When you adjust your carburetor for racing or install a new Carburetor, Racing Exhaust or High Compression Piston, you must properly tune the Jet
 
HOW TO SELECT YOUR JET:
Jet selection is a bit of a trial and error effort because many factors effect the fuel system
       
 To find the correct jet, start with a large jet such as a 160 or 150 and move down number by number until you achieve optimal performance. If you engage the choke at full gas and this results in poorer output or lower RPMs, you should change your jet to a smaller number. The stock main jet for these carbs can range from 100 to about 130
 
Your Main Jet is too small when engine runs better when the choke is engaged. Your spark plugs will look white and your engine will ping. If this is the case, simply increase the jet size until you find the right size. When the correct main jet is installed, your engine will run smoothly at full throttle and your spark plug should be light brown
 
NOTE: This page starts out with a $3.95. Jets cost $6.95 each. Choose the desired jets and the price on top will adjust. This is done so that we can have all the jets on one page
