Hey bwalsh,

You have a pic of your clutch side grips installed with the old throttle tube on there? Just want to know how it looks...

I kinda hate to dog pile, and I'm guessing you don't realize how you are coming across. It is a bit hard to come across in the tone you want with only written words. My guess is, when you are writing your response they sound helpful to you. But to some of us they are coming across as bwalsh stated. I'm a piss poor writer, just hope I don't come across too bad
Everyone has a different writing / reading style. I've maintained respect for everyone whether agreeing or disagreeing. I know what I know and don't propagate misinformation, and I try to be clear in differentiating my opinion from facts. I've already apologized to Bob for being snippy with him but he doesn't want to let it go. He's really a very nice guy in person but my writing style rubs him the wrong way. I can't change people's perceptions of tone. Some people give more latitude than others when interpreting the written word. And knowing a bit more about a person such as their political bent can influence how people ascribe motives. But not to worry as I can't continue to keep up with this thread anyway particularly now that the weather is warming and I won't be so cooped-up checking out what folks are up to with their xrls learning stuff and offering help and/or spicing up the conversation. I do appreciate the folks here and wish everyone the best as I poke in and butt out - folks on this thread have helped me immensely over the years and it's on-balance a very positive experience so I try to give back to the best of my ability. You can please all the people some of the time, and some of the people all of the time, but...

I also forgot to mention in that post I added Colloidal Silica to the G-flex to thicken it up to a paste like consistency so it wouldn't run.
Hung over now too...

Nice retro look with Honda reliability. I love that rear tank.

I think cabin fever is setting in.


So the welded bung is actually for a Bosch wideband O2 sensor. I was originally planning on just hooking the O2 sensor up to a microcontroller like the Arduino, which I could do with a narrowband O2 sensor, but the wideband is a bit over my head and I want to get this project done quickly. Wideband O2 sensors require a controller for the pump circuit- it actually draws atmospheric air in through the wiring harness.

I bought an AEM kit that includes the sensor, gauge/controller, and wiring. It has both 5v and serial data outputs for data logging. I'm planning on logging the O2 data and throttle position via some kind of homemade TPS sensor. I'm going to try using a Raspberry Pi board with an analog input adapter for the data logging because writing the data to an SD card will be a piece of cake. It would be nice to get RPM also, I'm just not sure how to do that yet. I'll publish some graphs once I get it all working.

Also, for anyone who hasn't cut open an FMF Powerbomb, it's curious. I was expecting to see lots of holes in the inner pipe like an exhaust resonator, and while it does have some holes, there weren't many that I could see. I just figured it was nice place to install the O2 sensor so that it wouldn't obstruct exhaust flow.

This will all be temporarily mounted - I'll do the initial tune with it for 8500' and then just use it to re-tune when visiting lower elevations like Moab, etc.

I hope this helps you understand specifically what's wrong so you can work on improving, not just for here, but for life in general.

This is an awesome project! If only we had an OBDII connector....
As for picking up RPM, one way is to tap into the switched side of the coil, filter / scale appropriately (protect from over-voltage spikes getting to the chip), and send to a pulse counting voltage output (tach) chip scaled to the A/D input span. Something like figure 3 & figure 14 here. Another way to pick up the pulse is to inductively couple to the high tension wire leading to the spark plug by wrapping an open-ended wire a few turns around. Note the latter is easily loaded and requires a high impedance input, perhaps an external buffer. It's also possible to monitor the voltage on the crank sensor for the pulse train, but that could increase vulnerability to interfering with ignition operation if not done very carefully. If you would like further details, feel free to PM me and I'll see if I can dig up some of my past designs. It's been a few years so it's likely to take me a while to locate.

Let it go? I get tired of seeing you do the same thing to everyone else day in and day out. Some over look it. I've seen it here and in the regional thread. It detracts from the threads.
As far as an apology, as usual from you, it didn't come across as intended...

Quote:
You're a proud man, Bob; I'm sorry you are offended at my help.

There's a lot of other guys who'll be glad to help you, though, since you haven't pissed in their beer yet.
Maybe you can work on that!

I'm done detracting from the thread with this mindless dickery...I apologize to all and hope I didn't piss in your beer too.

You're in luck! I'm switching handlebars over and have a few close up shots. The yellow and white piece is the tube. There is no way it will ever slip on the handlebar. Like I said, I had to persuade it on with a rubber mallet & 2x4.


Since the heater pad isn't quite wide enough to cover the entire tube I installed the left side heater with the wires up top figuring I'd have more heating elements on my hand. I installed the right side upside down form the left so the wires wouldn't be in the way. You need to give them some room to move without eventually breaking from the throttle being used.



I may do away with the zip tie and just tape it under the grip.

Thanks for the tach chip info.- I'm going to look into that. I like the idea of tapping into the low voltage side of the coil.

Hey Red,

On the topic of the stripped splines and the case splitting to replace the countershaft (and maybe 2nd & 5th gears and the lazy spring and the kicker....), I re-read your 2009/2010 posts on TT regarding the XR600 + XR650L franken-improvement. Amazing job.

There was a question that never got answered (maybe it did elsewhere, but I never found it). Please comment about the kicker working (or not) with a dead battery. The hypothesis is that the kicker will not start the bike with a completely dead battery, because the CDI requires a small amount of juice. I think that you said that you would just disconnect the battery, kick it over, and then hook up the battery. In these past 3 years, have you ever had to do this?

Why do I ask? Well, the primary reason for installing the kicker would be my fear of a dead battery, stuck somewhere on a muddy road (where bump starts would not work). But if the kicker won't work with a dead battery, then what's the point, right?

Please illuminate me.

Thanks, PD
