All specifications are either in the Zen or CY manual. The CY is all so in all the HPI baja manuals. Being a motorcycle mechanic and machinist for over 35 years I believe in proper torque. Have to wonder if some of the problems with the base gaskets on 2 bolt engines might be do to improper torque.
 
I am almost positive that was the problem in my 2 bolt. I lost that thing due to lean condition and very little dirt. I also think that choke plate for my 813 let in dirt as well. I will start it differently now.
 
sorry but these settings are wrong, you guys are forgetting the point between the numbers,
heres the correct ones from zenoahs website

Nah they were not wrong but in kg/cm the ones you posted are in N/m
 
Copied the latest specs from the latest engine here (G320RC)

The "Cover, TR" is not valid for the smaller CC engines (does not exist on those)
