I run a head stay but I don't have the cylinder head bolt in.

I dont get what everyone's aversion is to running the head stay bolted in? Why would anyone consider not using it?

I don't run one. I cut the mounts off to shave weight too:)

Last time I ran the head stay bolt it broke the mount in half. There could have been other factors but i replaced the mount and left the bolt out for the hell of it

I run mine without the bolt holes don't line up with the cool head

If you can run it, do it. I added mounts on both of my 89's for the lower rear mount, went with 3/16 steel mounts, that motor is in there solid now.

I run one also. It didn't line up with my cool head, so I put a smaller bolt in it. Now that I have a spacer plate motor, it lines up LOL. Still using the small bolt tho. Have another coolhead where the bolt hole isn't slotted like my newer one. They also made some with no head stay mount. Part of the reason I haven't built my LSR frame is that it didn't come with a headstay from it's PO. He just raced flat track with it btw. Whether you choose to bolt it to the motor or not, I do believe it's important to bolt it to the frame at least to help stop frame flex/stress.

I've always wondered this as well. Always ran one but have cracked/broke every single mount on my bike. Remade the lower bolt-on mounts out of .250" Aluminum, remade the middle lower mounts because they both broke off, fixed the head stay and now it's cracking around the lower square tubing down by the foot pegs and right in front of the middle lower mounts. Has to be a vibration thing in my case because I just do light dune riding, maybe the bike is reaching its' natural frequency with larger bores and beating itself up like the Tacoma Narrows bridge!!

I don't think the type of riding plays a major role in the motor mounts breaking. Obviously other frame tweaks are caused by different types, but at the end of the day, I thinks it's all due to our high performance engines vibrating the heck out of us that causes the breaks. I just repaired all of my mounts this winter. It's something that is just gonna keep happening I think, even tho I added an extra mount and thickened all the others
