Question about Motorcycles
Got a 50 aprilla engine in tzr n electric start but when I go to turn it on nothin starts just the digetal mph clock..sum 1 said clean the jets or the tappits no clue were they are??? Help
As far as I am aware, Aprilia only make 2 stroke engines. These do not have Tappets. The jets are in the carburetor. Does the engine turn over? does it emit oil or fuel from the exhaust when it turns over? With a 2 stroke engine you need to do a de-coke about every 1500 - 2000 miles. It is an easy job just requiring the removal of the head and giving it a good clean(with a stiff brush).

Just remove the carb, turn upside down,undo the 4 screws holding the float bowl on,and the jet on the top is your main jet and can be removed /replaced using a 6mm spanner.The pilot jet is lower down ,closer to the front of the carb and can be removed with a screwdriver.
There is also the needle jet which is held in by the main jet and can be removed by simply tapping it down once you have removed the main jet.
But for basic tuning you need only change one jet(main jet).
Please leave positive feedback if this has helped you

SOURCE: my tzr 250 is backfiring.
A back fire like that can mean an electrical problem.
have the coils checked
it could also be as simple as a short in the cut out switch, or a worn ignition switch
