Main stud torque was created by kaw74z1
Hi, would someone help me out on this, I am installing a set of used APE main studs with nuts into a kz 1000. My question is what do I set the torque at? Thanks in advance

Don't think X rings are available qanymore. Can you measure the thickness of the old rings?

hmmm... for some reason I thought it was higher than 20... well today I put my kz650 together and they're tightened to 70ft/lbs... I guess I must be lucky that they held up lol.
