upper engine mounting bolts keep loosing up

its been my experience if I red lock tight a bolt and torque it and it comes loose- I need to clean threads and use lock tight primer but if threads are loose - over the normal clearance then I use green as it can handle gap over 10 thousand of and inch..
that said I'm also a fan of safety wire- it gives me peace of mind and looks professional to boot!! :)

I marked the tightened bolt heads for front and rear cylinder, put a dot on the face I wanted to drill with a sharpie. It was important to make the wire wrap partially around the bolt head on each bolt to create a loosing/tightening effect.

I Drilled the bolt heads and reinstalled them, Then used (stainless steel) wire to make the tie.

run one end of the wire through the bolt hole so you are working with two wires.

Twist your two wires very tight with pliers as you go and keep the twist going right up to the other bolt hole where you run one end through that bolts hole.

I went behind the center stabilizer bolt.

This outta do it!

If one begins to loosen it will pull the other tighter and vise versa.ThumbUp

Note: how the wire wraps around the front face of the bolt in the rear cylinder and around the back of the bolt face on the front cylinder? that would be correct.

That should keep them tight, nice looking job.

It's sad when you start nitpicking your bikes little problems to keep yourself from going ballistic on the paint shop who is dragging their feet and keeping you off the road?

Fer cryin out loud these are supposed to be winter projects!

They should have been able to bang out that job, some fiberglass work and black paint. Doesn't get much easier than that.
 
I last time they loosen i went to my local hardware store [Remember them] And bought 2 # 8- 9-1/16 bolts that are treaded all the way.. Unlike the Stock bolts... Added a little tread locker ....So far their tight since Aug/Sept.....
 
For those with bolts that are constantly vibrating themselves loose, replace the bolt with a grade 8 stud lock-tite red and thick flat washer then self tightening nut (not nyloc). Make sure you replace the stock stabilizer link with the velvet-link. It might also help to install rear swingarm stabilizer bushings too.

Just curious....Where does the nut go... The bolts thread directly into the head [Blind Threaded] :Shrug:
 
These are on the EVO and up to 2007 TC engines for trike application, not TriGlides. The top horn bracket attaches to it. It bolts to both cylinder heads. Replace the bolts with studs instead. If the bolts fall out, the horn blows when going around corners.:pepper:
