When I park the bike after a ride I get 2 stroke injection oil on the floor cannot see anything obviously broken ie injection lines etc nor can I detect exactly the leak location
Any ideas

There is a weep hole by the oil pump. If anything in there is leaking, that's where it usually escapes. With a small leak, following the trail may be difficult. Take the cover off over the oil pump, and you will probably see the oil, but finding which o ring, line, etc is actually leaking may be a bigger problem.

What Lane said. Also check the delivery tube from the oil tank down to the pump.
My old 380 had a
tiny split in the tube where it connected to the oil tank, and the oil ran down the outside of the tube, under the oil pump cover, and pooled around the oil pump before dripping onto the floor. Probably no more than one drop of oil every couple hours. But when the bike's in the garage for a week, there was enough to drip onto the floor.
That caused me some fun and games until I noticed the tube was a little sticky with oil residue, I can tell you

Hi,modern synthetics two stroke oil is very thin and can leak past the gaskets & O rings/ banjo seals,check the pump at the banjo connection for tightness,pump may still have an internal leak problem with worn seals/gaskets though.
