Ok, finding stuff for the Scrambler is not easy. And some of what I find seems to be poorly thought out.

For instance, I want a skid plate. But the 'official' skid plate stops short of the filter! You still have to remove the skid plate (unless you grind a crescent into the rear end) to change your oil filter, but 99.9% of the filter is hanging out there to get a nice big fat hole punched in it. So, I guess I'm going to have to try to get a proper skid plate fashioned.

And, so far, I'm not impressed with the after market exhaust systems pushed by Triumph. The Arrow does NOT fit the retro look of the bike. And the sound files of the Arrow have a sharp cracking sound that used to be associated in my mind with a crank rod about to fail. <G> The TORS slip ons fit the look, but there are unanswered questions about tuning requirements, plus they are a bit pricey for just slipons. With tax and shipping, even with a 'new bike' discount, we're looking at close to $500.00. Maybe I'll just live with the stock system for a while. After all, I should have some faith in the Triumph R&D engineers.

The luggage rack...I've found this one, which looks fair... http://www.newbonneville.com/html/renntec_sports_rack.html In black, it fits the look of the racks that bolted onto the grab rails of bike back in 'the day'. But it is a bit pricey compared to the Triumph version. With shipping, we'd be edging up over $200. (I think the rack for the Valkyrie was $75!)

I guess the next item on the 'to do' list is to engineer a lift adapter for the Scrambler. Then I can get the measurements for a real skid plate... Aluminum alloy plate would probably suffice...and is easier to work.
 
Doc, I have not seen the insides of the stock scrambler silencers. But can you drill them out as we did the the Bonneville stock pipes? Can the rear baffle be removed? I welded a 3/4 inch bit on a steel rod and used it to drill through the interior baffles on my 03 T100. It sounded better than TOR's and was much cheaper to do. I also removed the rear baffle. I have no idea how doable this would be for your pipes.

Carl, Gary sent me info on drilling Bonneville baffles. And I have in fact drilled baffles on an employees bike years ago (Suzuki). And I drilled a lot of different baffles in decades past. I've found several problems with drilling baffles. First, drilling can shorten baffle life. I don't know if it is changes in the hot spots in the baffle or structural changes, but I have had some that just got 'sick' and sounded worse and worse.

The other thing that has bothered me about drilling baffles is the sometimes unpredictable results in sound. And of course, the results on more modern lean burn engines can be disastrous. I've seen a lot of youngsters seriously shorten the life of a high quality engine. So, if I proceed with such an experiment, I'd have to have a lot more info than I think will ever be forthcoming. There just isn't a good quantitative engineering analysis for such a modification. And of course each attempt at such a modification is likely to have several differences in technique that would make it real hard to gather meaningful data for analysis.

Now, that said, an engineering firm I've done some consulting for has a ground penetrating radar unit. I can't help but wonder if I might use it to get a peek inside the Scrambler baffles. LOL...
 
Doc, I wonder if that radar would work; it is worth a try. The drilling baffles I have done was on carbed bikes. I think you would need to remap an EFI bike to compensate for the freer flowing exhaust. As you said, these engine run too lean stock from the factory. I have remapped my Tiger XC to richen it up a tad.

I am assuming the "20 minute tune" will be all I need when I put the Norman Hydes on, the manufacturer says no re-map is needed.
 
That will probably work. But I am skeptical about how lean the engines run to meet emission standards. I would dyno it to see the air to fuel ratio. Even though Triumph has a map for the Tigers with Arroyo silencers, I remapped it to richen things a tad. I do not like running and engine on the ragged edge of lean.
