In simpler terms....
But, if you told your Harley buddies that they could strain their Sterno Juice through a Palladium honeycomb catalyst and then drink it without any ill effects and that a pyrometer was like a rectal thermometer as it measures internal temperatures......they'd understand that perfectly. Especially the rectal part. I've always been told that Harley types were anally retentive.
The more I thought about my post last night, the more I thought I should have probably said that the "firing off" of the Palladium substrate in the cat box is depended on temperature just like, if you will, a Coleman catalytic heater which I'm sure everybody (I think) has seen in operation. If you retain the loaded cat box (see stamped "C" on the side, may be upside down), it's important that the exhaust is hot, hot enough to start the catalyzing process and drive the H2O out of the substrate. That's why when you start your bike even in the summer, it "smokes" a little.
Triumph refers to their O2 sensor as a Lambda sensor. I prefer O2 sensor. Lambda sounds too European to me.
I'm sure you remember in the late 60's and 70's before the advent of multi port FI and TBI, carbureted cars still had cat's and more than once I've seen the cats glow from too much fuel and too little oxygen. EFI took care of that along with more sophisticated computer control of the fueling. I believe the only place you can find a choke plate these days is on your lawn mower.
There is one more IMPORTANT point to add and it refers directly to the first post in this thread and that is:
If the charging system on the R3 is anything like the system on the T100 and comparing alternators in both workshop manuals other than output and physical size, they look like brothers, you don't need to hold your engine at any rpm more than just above an idle to produce the maximum charging amps from the alternator. In all actuality, the amperage actually falls as the rpm is advanced above just over an idle. Both bikes have a solid state regulator and probably from the same supplier so I assume that the charge curve of the R3 is similar to the T100. You don't need to whack on it to charge it up. Better yet, get a battery tender for 40 bucks and save the wear and tear on the engine and quit stink'in up your garage.
