Has anyone figured out the torque specifications for the 2 cycle engines? Looking for ones for the 80cc motor.
Thanks
Jeff
 
Thanks I found this information on here for the head nuts.
Torque 8mm to 120 to 175 INCH POUNDS
Torque 6mm to 60-70 INCH POUNDS
Thanks
Jeff
 
I use 8mm head bolts at 10 to 12 foot pounds & 6mm bolts at 6 to 8 foot pounds. Using those values for over 8 years on getting close to 1000 motors now.
 
kenm, you're thinking in foot pounds instead of inch pounds. 175 inch pounds is 14.5 foot pounds. 18 foot pounds is too tight.
 
Max torque for GOOD cast aluminum 8mm is around 204 inch pounds which is 17 foot pounds. Being we are talking about Chines cast aluminum I sure would not got to the high side or max.
Thanks Jeff
