250cc Rhino chain Q/A

[Paul2]

morning all,,
250CC rhino and 150cc bulls;
how do I get the best or lets say "correct" chain tension on each??
I've ridden and haven't touched in a bit and would love to know if I'm on borrowed time or too tight ect...
Maybe a tension tool someone recommends or a guide someplace online, or a trick you have for these ATV's
ps- Is there an official tension spec setpoint?
Thanks again
