RSY Beauty Megaphone

I’ve been wanting a new exhaust for Tux for a while now. The factory muffler is enormous, heavy, tends towards rust at the end, and is almost silent.

I’d tried out the inexpensive slip-on Mini-Norton from Dime City Cycles, but it was too flipping loud (distractingly so while moving) and it required a full stack of adapters (and tape!) to make it fit Tux’s exhaust pipe. It also required me to craft a bar to support it from the frame, which left it somewhat unstable, putting more force than I’d really wanted on the exhaust header screws. I ran with it for a day, but had to retire it due to the sheer ear-wrecking volume.

Some time later I happened to run across photos of the RSY Beauty. It’s designed specifically for the TU250x, and rated at a sensible 89dB. Promising!

I ordered it from Web!ke as an early Christmas present for myself, and was surprised to discover upon its arrival that it was actually a full exhaust system, not just the muffler. The exhaust header is stainless steel to match the muffler. It has some built-in baffling just after the port for the lambda probe. The muffler itself has only a minor cage baffle, and is very lightweight. It has a tab that fits with the existing mounting bracket perfectly. It’s louder than the original muffler (which was ridiculously quiet), but not ear-bleedingly so like the Mini-Norton was. It has an overall pleasant tone, nothing too tinny or sputtering. It does suffer from an occasional roll-off pop, but that isn’t a huge deal.

I recorded a short video of my kicking Tux over so people could get a feeling for how she sounds now.

I’m considering wrapping the pipe in black, since it seems to shed a lot more heat than the original pipe had done. It went blue-gold in less than a day! I’ll have to think about it.

The TU250x Kickstart Guide

I’ve finally written up and vastly expanded upon the information I originally had been posting in the “Kickstart for the TU?” thread on tu250riders.com. It almost certainly will go through a few more revisions, but it’s in a state now where it may actually make sense to other people!

So check out my TU250x Kickstart page, which details the changes needed, the part numbers, and the work required to make it happen!

edit: I’ve rewritten bits of the guide to make more sense, and I’ve added Amazon.com links to a number of the tools or consumable items that are required to get the job done.

Surprise, There Are Users

My motorcycle is in the shop this morning. I ride a little TU250x that I call “Tux”. I bought her for myself as a birthday present last year, and have put a little over 6000 miles on her since. She’s a good bike, and I take a lot of pleasure in our rides together. I perform the majority of her maintenance myself – oil, chain, valves, electrical. But one thing I didn’t want to do was replace and balance the tires, so I’m paying the guys at Team Powersports to do it.

While Tux is off getting new tires, my daughter and I are sitting on the back porch. She has been reading Rurouni Kenshin for the first time, and I have been working on the documentation for python-promises.

Javatools to Setuptools

I was supposed to write about sibilant, but of course I’ve been distracted.

My daughter is out of school on spring break, and I’ve taken leave from work so that we could hang out together. Of course this means that we’ve just been finding new ways to ignore each other as the week has gone by. We’ve certainly spent a lot of time at various parks and playgrounds, and we’ve played an awful lot of Minecraft together. But on the evenings we’ve also set up something approaching residency at our favorite coffee shop. She will sit and munch on chocolate chip cookies while watching videos and playing games on her ipad– oblivious to my presence– and I’ll find myself looking for something unimportant to half-heartedly hack on. It’s a pleasant and relaxing situation, this modern bonding.

And so it came to pass that I was looking over the python-javatools project again.
