on my ttr 225 i had lots of problems with my chain if i had it too tight it would come off and too slack it would come off the reason for that is because i had it way too tight one day and plied one of my sprockets. and yes popping the clutch will stretch it. i think it should be half inch slack? im not sure if u got a after market chain like a poopy one it will stretch after a 3 or four times of riding like mine done. but if u have the stock chain that came with the bike i don`t think u will need to tighten it that much once a week maybe

Just my 2 cents. On what I have experienced, most bikes, depending on application, need about 1 inch to 1 3/8 of play up and down. If you are too tight or too loose two things will happen... Your sprockets and chain will wear rapidly and your chain will come off. If it is close and those two things aren't happening, you are problably ok.

Just because the bike revs high doesn't mean it is making a lot of horsepower. The chain should be adjusted to accommodate your style of riding. If you jump a lot and use the entire travel of the wheel and suspension, you will want the chain on the looser side because as the bikes suspension compresses, the wheel moves farther away and thus there is more tension on the chain. If you ride simply trails and or stuff like that you won't need as much play. I adjust my chain to about 1-1/2 to 1-3/4 of slack because I ride pretty much everything.
