2013 Honda Foreman Trx 500 running rough

[Chrism]

Hi all, new to this forum so thanks in advance for the help.

I have recently brought a 2013 power steering fuel injected foreman 500.

It has a crack in the front casing and was running rough. I have since replaced the front engine casing and this has made no difference to the engine performance.

It starts and idles but bogs down and starts to die once throttle is applied.

It maybe be but it also sounds very load.

I have uploaded a video link of it.

It sounds like the timing is off

what does the front casing cover on these bikes?  maybe something screwed itself in there and the cracked case was just a symptom?  yea obviously theres some valve ticking or something going on in the top end but cases dont just crack themselves.. either something hit against it from the inside or from the outside.  maybe if it was from the inside then thats affecting the top end and maybe its a different issue all together.
