1997 Chevy s10 V6 truck multiple misfire code keeps coming on changed wires plugs cap rotor tierd of spending money and problem still not fix?

Remove all the spark plugs and run a compression test on every cylinder. A misfire can be caused by a burnt valve, cracked head, or blown head gasket. A compression test will eliminate any of these possibilities. If you find a cylinder with low compression, then it may be time to open it up and find out what is going on. If you have a sweet smell at the exhaust, air bubbles coming from the radiator, loss of coolant with no apparent leak, or coolant in the oil, these are all symptoms of a blown head gasket or cracked head.

How many hours of riding before a ktm needs rebuilding?

it's better to base this on a pattern of compresion tests, sound of the engine, feel of the performance. most manufacturers recommended rebuild schedules are way too frequent. i don't think ktm had a recomendation on this. if you are doing a compresion check after every ride the time to rebuild would be when the rate of compression decline takes a more sudden dip.

Could it be bad compression that your 87 ford 302 efi runs terrible when cold you replaced heads intake gaskets head gaskets every gasket on top of motor and no luck?

yes in short the metal contracts when it is cold thus giving you less compression, that or it has scratches through the cylinder sleeve or it could be a bad ring but if its the whole engine not just one cylinder its the cold u just need to let it warm up more

2002 Chevy Prizm and you keep adding oil every three or four days you do know that the compression in one of the cylinders is gone your car has about 90.000 miles on it any help?

Open the engine and change the rings, valves, valve seats or pistons in the one with no compression. Or, try synthetic motor oil, it doesn't burn as quickly.
