my quad suzuki 700 2006 cranks slow untill i cover the throttle body restricting air then it cranks fast

 

Battery flat, or bad connection between battery and starter, this includes the earth side.

The 700 had two design problems, the ECU takes a fair bit of current when the engine is switched off, and the charging circuit wiring was poorly thought out, and max charge is about 13.25v, hardly enough for any bike, let alone one that leaks current when parked up. So flat batteries are common. A re-designed ECU, which takes less current, was available (expensive), or you can disconnect the battery when you aren't using the bike. The low charge problem is easily fixed, just piggy back an extra live and earth wire direct from battery to voltage regulator red and black wires. The live should go through a fuse.

 

Hi there i cleaned every thing up battery fully charged and still doing the same. Could it be that the timming might be out?

 

Highly unlikely, did once have a 500KQ that broke the flywheel key and put ignition timing almost 180 degrees out, and a 700 that seized a cam and put valve timing out, owner had run it out of oil. Most likely a bad battery. You can check that the T mark is where the piston is at the top with a rod down the plug hole, but be sure not to get it jammed or you will damage the thread for the plug.
