New motorcycle nutral problem?

Just bought a new bike( 94 honda magna 750) it runs flawless and shifts flawless while driving, but i notoced sometimes i cannot get it into nuetral. Most time it slips right in,but sowlmetimes it goes in and pops right back in first.then i roll bike back like ten feet and usually it pops right in nuetral. Its a problem because the bike has to be in nuetral for it to start,even if i pull clutch in like anyol other bike iv road.but like i said driving it shift into gears perfectly and MOST of the time it goes in nuetral without any problems. But sometime it just pops tight back out,the nuetral light wont even come on when it pops out,which i know it works. Please gelp. Simple fix possible or big expesive one? Thanks for input
