I can't get the secondary injectors to come in. My bike revs to 10000 and that's all it has and that's not high enough to even get the shift light to come on. Really need my speed
SOURCE: Lack of power and low revs
Remove and clean the carbs. Remove and clean the fuel petcock water trap then put everything back together. Try the bike now.
If still bad then take it to the shop and ask for a compression check. You may have some burned valves.

Running well at high revs would indicate that all the fuel and air it needs are getting to the engine and you also have a good spark. Probably no problem with air and fuel filter ( if fitted) or sparkplugs.
Running hot, and bad idling are signs of a lean air fuel mixture. The engine is probably not getting enough fuel at low revs.
This could be caused by an air leak between the carburettors and the engine. Check that the vacuum line to the fuel tap is properly secured at both ends. It is behind the fuel line at the tap.
Get a a short length of hollow plastic tube and use it like a stethascope - put one end to your ear and move the other end around your carburettor mounts with your engine revs as low as you can get, and listen for any sucking noises that would indicate a leak. Look for cracks in the rubber inlets.
The other possibility is that there is an internal blockage in the idling jets or idling fuel circuit. This is where dirt tends to lodge because the jet dimensions and passageways are very fine - The high speed jets are much bigger and dirt often just passes straight through.
Try a little bit of choke while the engine is warm to see if you get a stronger low speed response. If so that would point to an internal blockage.
SOURCE: bike idles, but with a little throttle it jumps to high rev and wont come back down to idle
You need to oil your cables first....They make a gadget to help you do this...it clamps around the end of the cable, and you spray oil into a provided hole for a spray nozzle tube...Then see if the cables are unstuck by turning the throttle grip back and forth for awhile....start it and see if that helped....if not you may need to replace the cable(s)...I doubt that the slide in the carb is hanging up...or valve.If this doesn't work notify me.
SOURCE: my dt 125 is not quite right, revs are stupidly high & carb leaks
your needle valve in the carb will probly have a little stone in and it is allowing to much fuel to go into the carb causing it to overflow
