what components wont let a 95 kat 750 wont start? my kat has spark, all the fuel lines are connected, its pumping gas, but its not starting i throw carb cleaner in the air filter area as i crank it and it starts, it stays on as long as i keep pumping carb cleaner but normally it wont start so what could be a cause of why is not starting?

+1 to what Paul said.
You only need a few things to run an engine: fuel, air, spark, compression, and timing are the big ones. Assuming your engine isn't toast we'll cross off timing... and hoping for the best we'll cross off compression as well, because no one really wants to rebuild an engine. So fuel, air, and spark... the most common culprits for starting trouble. You know you have spark (I guess you pulled each spark wire off and watched it while you cranked... that and the engine fires up with certain fuels).
If other fuels (like starting fluid (ether), or carb cleaner (toluene and xylene mostly, I think)) get it going, it means your problem is probably fuel related. Ether is great because it has it's own oxygen, so it will get an engine to fire as long as there's spark. Toluene doesn't have it's own oxygen, so my guess is you have plenty of air supply (not sure from your post if you have the air filter removed or not when you're spraying in the carb cleaner... I assume it's removed). What you are most likely lacking is enough fuel.
Maybe a good rule of thumb is to always suspect the most complicated part of a system to be the source of failure. Carbs are pretty complicated... and they're almost always the problem.

well spark and the big problems are out of the way, the airbox is off what i don't have connected to the carbs are my vaccum lines but because the place where the vacumm lines go into, are broken on the carb, so i can't connect them, would that be any problem?by night and day, we'll keep riding until one day.... we may pass away

You need vacuum to operate the petcock, which allows fuel to flow.
You are saying the fitting on the carb where the line would attach is broken?-Steve

You'll need to address that leak, and you can tap vacuum off any of the 4 synch ports on the carbs.-Steve

If the port that the vacuum tube was attached to is broken, you need to cap that part, and draw vacuum for the petcock from somewhere else.-Steve
