please some one explain what and how these things work!?!?! a timing plate,reed spacers i know i have them but they came with the bike, airstryker and pw carbs? also the difrance between a long rod and a stroker crank, ADJUSTABLE IGNITION STATOR PLATE ADVANCE TIMING UP TO 7 DEGREES,tanks for the input everyone please tell me im bad with the electical stuff and to me a carb is a carb i know size is helpfull but typs and styles idk anything about iit:-D
what do these perfomace parts do??so i dont buy somthing that doesnt work

timing advance plate mounts behind the flywheel and controls where in the pistons compression cycle the spark fires. say your stock timing is ste to fire the spark plug when the piston is TDC (top dead center). with a +7 degree advance you will now get a spark 7 degrees before the piston hits TDC. the degrees are measured in terms of the crankshaft position. 0/360 are TDC while 180 is at the bottom of the pistons cycle.
a reed spacer can be placed in 2 diffrent configurations to suit your motor. if you put it between the reed cage and carburator you get smoother airflow into the reed cage. if you put it between the reed cage and motor, you get a smoother flow between the reeds and ports that lead to the combustion chamber. it has been argued many times about which is better. personally, i think they are junk and belong in the same trash can as a boost bottle. the only rock solid reason to add a reed spacer is when you need the extra clearance due to a carb upgrade.
stroker crank is exactly as it sounds. its a modified crankshaft that allows for more piston travel at its top and bottom limits. +3 millimeters is the most common one you will see on a blaster. that gives you +1.5 millimeters at the top and +1.5 millimeters at the bottom of the cycle allowing for more air and fuel to get compressed creating a small to moderate increase in power depending on your port size and flow.
a long rod is nothing more than a longer connecting rod. it maintains the same stroke as a stock crankshaft but moves the piston closer to the head when TDC. this compresses the air/fuel mixture tighter and gives a bigger bang when the spark fires. the same effect can be obtained when you shave the head surface with a lot less trouble and expense. this usually requires a higher octane rating on your fuel and can often lead to serious issues if you dont calculate the minimum octane needed correctly or shave off too much and the piston makes contact with something its not supposed to.

that pretty much sums it up!
but i will add that i have noticed a slight increase in the bottom end when reed spacers are added between the reed and the motor

think about whats happening. once the fiel is ignited the piston is still moving upward against the explosion. so when the piston is finally allowed to be pushed downward it will be forced down even faster. the amount of advance is a very small amount when it comes to the piston being before TDC
