Have a nova mmb messtechnik on my tw. Works good. Looks nice with a blue backlight.

Don't much about it cause I just got the bike and it was on it already.

Seems to be a universal fit.

I just installed the Koso mentioned above, last week. I love love love it. I wanted an analog gauge to match the outdated stock speedometer on the TW. It matches fairly well. The blue light stands out quite a bit at night, it's easy to look down in a flash and catch your RPM. I wish the shift light was slightly brighter. It's hard for me to see using peripheral vision.



The install took me about 2 hours, and thats including soldering and heat shrink tube wrapping the connections.



Thanks to Novaks44 for the following info:

"I recently bought a Koso tachometer for my TW. It's model number BA481B17, and can be had from DennisKirk.com, for $108 and free shipping, which is much cheaper than other places charge for lesser tachs. I like it because it's small, but easy to read, and has a shift light, which I doubt I'll use much, but it's neat just the same. The install was pretty easy. First, I tried to wrap one of the wires it comes with around the plug wire. That did work somewhat, but the readings were erratic, and less than ideal. I then tried the other wire it comes with(type B as they call it), and installed it between the ignition coil and the orange wire that plugs into it. And that, is the way to do it! Perfect, accurate readings! I compared my results to the online gearing calculator for our T'dubs, and it appears to be dead on. The only other wiring, is battery positive, ground, and a switched 12V lead. Simple!"

"Another installation note I forgot to mention. When setting up the tach, there are two steps. First, choose the cylinder/cycle mode. The instructions are not very clear on this. Just set it up as their example, so that the needle is pointing at the 2 during this step. Next, you choose the "mode". There's two : Mode 1, and Mode 0. Choose Mode 0(needle pointing at zero), and it'll work correctly. You can check out the instructions on Koso's site, they're in .pdf format. If anyone else gets this gauge, and needs help, let me know! "



Those tips really helped me, because the instruction manual is very vague.



I found a dyno chart someone posted that listed the TW200. Here it is: dyno chart



According to that, I would program the shift light for around 7800 if I was doing performance riding/pushing it hard. I currently have the shift light set at 7grand for when I want to get on the throttle.

This is my tach / Hobbs meter (total run time in hours). It takes RPM readings every second so the tach is always a little behind. When I bought it it was $16 and now I see they are $32. It was easy to install. Last August I asked and they said if I bought 10 or more I could have them for $18.90 each.

Here the engine is off and it show 99 hours. If I start the engine it immediately shows the RPM. I have to add I like mine. For the price I think it is an OK deal.

Tw's fire once per revolution, twice per cycle.
