Great idea!  I'll get with Jud when he's back in town.

They vibrate pretty hard. Ive seen Why they break license plates,the fender was swinging side to side so hard I had to look twice, I thot my eyes were lying to me,

I agree,.. but I only have three thumbscrews now, though.

I felt the side covers on the next ride, and they really do vibrate a LOT!!  There is some sort of resonance at certain rpms that is pretty impressive.  I wonder how many RYCA bikes have lost their sidecovers.

I like your solution, Gyrobob.  I had that Emgo muffler on my non-Ryca Savage and had to retire it because it was just obnoxious loud and raspy after my repacked fiberglass blew out (again).

This makes the baffling design more on the order of the Dyna mufflers.

Back in the 70's, I rode a Ducati single with a small can muffler that had a similar baffle and it had a surprisingly good tone and lack of raspiness for such a small muffler.

The only issue I see with this is possible bluing of the cheap Emgo chrome where the exhaust gas gets forced out of the core and out against the outside of the muffler.  Time will tell, I suppose.

This is a great adaptation.......and very creative.  I applaud you for not wanting to be that obnoxious loud motorcycle that people glare at as your ride by.  I live 2 miles from a 4 lane highway out in the country.  I can hear the loud motorcycles and trucks without any form of workable muffler out on that highway, and I wonder why they want to be so darn loud?

The other thing that is a bit of a "bad idea" on this is - the shock is fitted to the original mount location right - ... the taller shock makes the swingarm sink lower making the belt likely to hit the swingarm on the top side. I would relocate the upper shock mount to somewhere higher up in the frame. Sorta where the seat ends - right under that.

Cool.

I posted earlier about the side cover thumbscrews falling out.  

The thumbscrews supplied with the kit are finger tightenable only.  The sidecovers vibrate so much, there is a high probability these things will work their way out unless you tighten them with long-nosed vise grips.  Then, along the side of the road somewhere, you couldn't use your fingers to get the sidecovers off.  The fasteners reside in places that don't allow much leverage.

Anyway, until I can come up with a better, more secure, more convenient system, these fasteners need more security.

My "bright idea" is to use small 6-32 screws with wing nut heads to get more leverage in those recessed areas.  I couldn't find any,.. so I made four.  



High-tech Home Depot aerospace plated alloy fastening devices:




Wing nuts silver-soldered to the screws.




Screw heads cut off,... threads tidied up.



This is not a great pic, but it shows one of the wing-nut screws with the "safetying" device (a nylon cable a little over a foot long with springs at each end).  This view is from the right side of the cylinder looking aft.  You can see the right shock, the side cover, the tire, and in the center, the lower right wing-nut screw with the nylon cable stretched tight on it.  One end of one spring hooks on to the upper right wing-nut screw, stretches the cable around the lower right wing-nut screw, then lower left wing-nut screw, then hooks the other spring on the upper left wing-nut screw.  


After two 1-hr rides, the wing-nut screws have not moved any.
