Hi all
I was inspired some time ago to make my A10 head steady rubber mounted - inspired by Chaterlea25's post about the one he made:
https://www.a7a10.net/forum/index.php?topic=2912.0As he said in that thread, without a doubt the original head steady mounting of the rockerbox cover to the frame contributes greatly to rocker cover joint leakage, due to shear stresses between the head and rocker cover. As I'd just re-torqued the head after a rebuild, and had fitted a new SRM rocker cover gasket, I didn't want to fit the original steady and have leaks again.
I've photographed the steady I made, and although nowhere as neat as chaterlea's one, it does the job. I was going to make a neater one, but this is version 1 - a quick, simple and easy method that I did to test the concept. Its done 800 miles so far (and I ride & rev my bike hard) and its worked well, with no leaks (yet?) - although it has to be said that the Bunn valve breather system that I fitted (described elsewhere on this forum) made a huge difference too.
I race a TZ350 that has rubber mounted engine fittings, and have used these rubber bushes on my T20 Suzuki Classic racer too, (see
www.t20suzuki.com for details), to rubber mount its engine to stop frame cracking and reduce vibrations. The Yamaha part number is 102-22123-00 if anyone wants one.
I took a used one of these out of my T20 frame and welded two mounts to it, as shown in the pics. Obviously this melts the rubber, so I had most of the rubber mount in water whilst welding it, then cooled it v quick. As I said, this is version 1...
I'll probably make a holder for the bush if I ever redo it (see my T20 page for an idea of what I mean), but this worked, and its still working well today, 800 miles later.
For those worrying about a 'steady' that moves, the actual movement is minimal, but more importantly it damps the vibrations down by a large amount, giving the rocker/head gasket joint a much easier time. The engine itself remains smooth and vibrates no more than it ever did.
