I find the power good at the moment Nato and if it wasn’t such an easy mod probably wouldn’t do it , I do like a strong mid range in a bike an the hot cams give plenty of that 
Plus who doesn’t like to find more power in their bike !!!! 
Yeah if when i had my wr250 it was as easy as that i would have done it plus nobody knows its done and when you spray the 450’s you can laugh and they wont know what got em
