Xlr 125 wont start do i have to pull the clutch in to start it

You need to put it into neutral in order to start it or pull the clutch and hold it down until started. I would suggest putting it into neutral. Double check that you have it in neutral by trying to push the bike without holding down the clutch when you think you have it in neutral. If the bike rolls easily, then you know its in neutral. If it won't push or seems hard to get it to roll forward then you know its still in gear. Once you have it in neutral (for sure), hold the clutch down and start the bike.

Othen than that, all you have to do is make sure its turned on and it should start. Some bikes use a key to turn it on, others have a throttle control switch. We had Suzuki Quad racers which were 2 stroke - and are a little different.
