Ltr 450 won’t start

Hey guys, I recently bought an 07 ltr 450 and buddy told me it needs valve adjustments and was hard to start so when I got there it fired right up no problem and I went to take it for a spin and it died before I got to the end of the driveway I tried to start it agian and just wouldn’t go so buddy says sometimes if you leave it for a while you can get it going agian so we waited a bit and tried agian and it was a pain in the ass to start had to boost it and tried for 5 mins before we got it going agian so I took it for a rip it had lots of power but when I brought it back it died agian so I loaded it up because I drove a few hours to get this and I was determined so when I got home it was indeed a pain to start and when I finally got it going it bogged out so I tried fresh gas with sea foam, injector cleaner and fuel stabilizer and that didn’t do the trick so then I cleaned the plug with an air compressor and sand blaster and it was practically brand new agian that did nothing checked the injector it’s squirting the fuel pump works all 3 lights work up top it’s got spark when I take the plug out it’s wet so it’s getting fuel I made sure the fuel screw was all the way out tried boosting it tried choke no choke throttle no throttle and still nothing it seems like it’s trying to start but just won’t catch any ideas what’s going on?? Is it indeed valves? Help me out guys thanks in advance

When the engine is running the valves get hot and grow making it hard to start when it is hot. I would check the valve lash.
