-====== Adjustable Main Jet (L76-87) ====== 
-There is an adjustable main jet available from J&P Cycles or others. \\ 
-These work great and you don't have to fool around jet guessing whether you have the right size main jet or not. \\ 
-They are simple to adjust. Just wind it up to about 65 MPH and run it in until it misses and back it out about a full turn. ((oldnavy of the XLFORUM http://​xlforum.net/​forums/​showthread.php?​t=877868&​page=2)) \\  
-This kit can be purchased online. It comes with an installation guide and index pointer. \\ 
-The tool marks inside of the float bowl (as installed) for drilling the proper sized hole to thread in the adjustable main jet.\\ 
-The kit can be purchased online. \\ 
-PDF instructions - [[http://​www.vtwinmfg.com/​instructions/​35/​35-0369.pdf]] \\

-This replaces the main jet (has to be removed). \\ 
-The float bowl has to be removed to install the adjustable main jet. \\ 
-A guide tool is included with the kit to install the new jet to properly index the carburetor float bowl. \\ 
-A index pointer is installed in the guide, bowl reinstalled and the pointer is pushed down from inside the venture to dimple the bowl. \\ 
-The bowl is once again removed and a 1/​16"​-1/​8"​ pilot hole is drilled followed by a 15/64" bit. \\ 
-After checking for burrs, removing the index tool and guide and cleaning up, the adjustable jet is installed in the float bowl. \\ 
-(partially unscrew the small '​T'​ handle so that the needle in the adjustable jet is not exposed to accidental damage) \\ 
-Remove the nut from the adjustable jet, insert the jet through the 15/64" hole drilled earlier. \\ 
-Then re-tighten the bowl and gently screw in the '​T'​ handle to the needle seat and then back it out 4 turns. \\ 
-Finer tuning can be achieved by reading the spark plugs and small adjustments to the “T” handle. \\ 
-This adjustable jet eliminates the chore of carrying and continually changing different main jets with every change in exhaust system or air cleaner. \\ 
-The hole in the bowl for the '​T'​ handle jet has to be indexed correctly in order for this to work. \\ 
-The adjustable main jet is designed to operate in conjunction with a 1.80 main jet included with the kit. \\ 
-Make sure you record or remember the number of turns off the seat and back off the '​T'​ handle before removing the float bowl later. \\ 
-This will help prevent needle / jet interference when the float bowl is reinstalled. \\ 
-For initial adjustment (standard pipes and A/C) it's recommended that the adjustment needle be backed out four (4) turns from the seat. 
-The adjustable jet set screw is turned in, towards the float bowl to lean the fuel/air mixture and out from the float bowl to richen the mixture. \\ 
-Check plugs frequently after jet adjustment, exhaust or A/C to avoid too lean or too rich conditions. \\
