Looking around I have not found much in options for case savers. I ordered a Carbon Fiber clutch guard from EBR but was not happy with the quality of the composite layup as the areas around the bolt holes were not filled in completely and had bubble like air pockets setup in the resin making for nice stress risers to fail over time with motor vibration + making for a poor seat for the bolts it does not seem like a good option.

Anyhow what else is out there?

I use top-hat bushings super-glued into the EBR part. I had trouble with the reliability of them around the bolt holes too, but these bushings cured the problem.

Taylormade Racing, I was under the assumption they were the same ones EBR was selling.

They are. But, if you call them, they might make a set with more layers than normal for extra protection.
I'm going by there today to discuss the mounting issue.
Also, Paul takes great pride in the quality of his product. If you find flaws, you should let him know.

I noticed when I mounted mine that there was a little 'crunchiness' when I tightened the bolts the first time. After two seasons and a couple of lowsides on the same case protector, I bought a replacement and never mounted it as the worn one was still in relatively good shape. They work!!!

I would be curious as to what you learn talking to him. I will post up a pic here of the one I got.

If that is the inside of the guard, the imperfections are from the engine case/mold and don't effect the performance at all. Normally, they trim the edge of the guard to match the engine case, because most people want them to line up. But that does not give enough edge area to install bushings reliably as above. So I got mine not trimmed as close to accommodate the bushings, and with 13 layers of carbon kevlar instead of 10.
That said, the unmodified versions have saved my motor several times. Including my 1190RS motor is the last big crash. I highly endorse them. they have saved me $$$$.

Imperfections are air voids with sharp transitions,Do you know what a stress riser is? + the areas around the bolt holes are not at all uniformly impregnated with resin. Carbon composite is stiff brittle and will fracture from harmonic vibration and this piece does have issues in that matter. The transitions could be ground out to relieve the issues but for the cost "I don't mind paying for quality craftsmanship" on the things that work should be done already or better yet the mold filled properly in the first place. I make things for a living and if I made this I would not be happy with the outcome and would not passed it on to an end user. I have had to reject my own work and others in my job it is part of making things properly.

Case savers are important and have saved me from issues in the past also, that is why I was looking for some and why I was unimpressed with the workmanship on this piece.

Seriously, the part I referenced above is the answer. Flange to the outside so the bolt head compresses it.

This will allow the torque of the bolt to directly fasten the case cover instead of the case saver, and then the case saver is secured with a large diameter bushing and held in place in a crash by the flange.

Ditto
I stand behind my endorsement based on how many times these have saved my motor.
But if you are unhappy with the part, send Paul a picture and explanation.

Well i am a picky ^$%#er and this type of thing gets under my skin I may send it back to EBR with the rotor when It goes out. Fixed the leaky clutch slave and pulled the stator to see whats going on on that side "Rotor is not modded" so I ordered the EBR rotor which should give me a week to get over my expectations with the cover and pull out the dremel tool and fare in all the sharp edges around the bolt side of the guard.

You have every right to be picky. It's your hard earned money.

Not sure if these exist off the shelf, but what you need are oversize(fender washer) washer with rubber on one side.

The more contact area you can get, the lower the psi and subsequent damage.

<edit> Jdugger's idea of a glued in top-hat washer is much more elegant and reliable.

Wasn't there a Brazilian doing these too?

I'll take some pictures this weekend of how to install and square them effectively. You only need a bench vice and a dremel.
