Re: Torque specs and bolt sequence 250 Inline 6
I usually go 95 ft-lbs on all but the front left (driver side) bolt, which is 85 ft-lbs. 90/80 is OK too. Follow the sequence shown in that image torquing in stages. All to 40 first, then 70, then to final. Re check torque after a few heat cycles.
Enjoy your 250 and welcome to the forums!
