This is not a single fire iggy.. It fires every time the piston goes to TDC, exhaust & compression.. Tell the person at the company that & theyll tell you if their tach will work,

This is exactly the one I run on mine since three years. Works great. Dual fire is the one you want.

Just a quick update to this post. (Kind of long and wordy, but I dealt with alot of frustration getting this thing installed) I ordered the black tach from this guy on ebay and when it showed up the bezel was bent in 2 places so I sent it back for exchange. When he got it he realized he was out of black faced tachs but offered the "upgrade" to the white faced color changing tach. I agreed and he sent it to me. I attempted to wire it and got the lights to work and change colors as described, but I was unable to get the actual tach to work. Reviewed the tach installation post and tried again, still no response with the tach needle. I sent a nasty email to the vendor telling him it was dead on arrival and he asked me to call him. Called him the next day and told him my problems. First thing he asked was what Hurley I was trying to install it on...told him it was an 05 Suzuki S40 Single Cylinder and he started accusing me that guys keep buying these for import bikes and he can't guarantee they will work. He re-explained the wiring, and a potential test to make sure I get the right lead from the coil. Also offered to refund the money if I sent it back and it was DOA. (This was back in early August, just this weekend I finally got back to trying to install it again) I tried his test of which lead to use from the coil. He said that 1 side of the coil is energized when the key is on and the other side should not be until the bike is started. No matter which way I tried to test it with just the key on both sides of the coil were showing >12v. I went back to the Tach post in the Tech section of this forum and verified which wire to use (black one with a stripe) connected all the wires with test leads (alligator clips on wires) and tadaa the thing worked as it should. I must not of had a solid connection the first time I tried, so this time I wired things up real well and now it works perfectly. Will post up some pics of it on the bike when I get a chance.

Here is the same one from the same eBay seller that I just put on...

I installed it the same way you did, wedged between the riser clamps. After a while I realized that this is the reason why the illumination bulb keeps crapping out every other week. The vibrations of the handlebar is too much for that location. It eventually broke something off inside the tach as well and it quit working. I got a replacement, same tach, but mounted it with the supplied rubber lined clamp.
Ever since, it's been two years, just one bulb replacement and the tach still works like on day one.
Just a heads up for you, that one mine I had to replace the bulb about every two weeks, and it is a real pain to get the socket through the hole with a pair of needle tweezers. There is also several different bulbs that look the same on first sight, but there is minimal differences in the thickness of the socket. The bulbs have different numbers and it nowhere tells you which on it is. So I just bought them all to find out. Turns out it is #2721.
I still like the look better, mounted like you have and I had the first time, but it will break stuff from vibrations, so I settled for the rubber lined clamp. I got used to the look and have no worries anymore.

Not a problem...which one did you get?

It's been a little while since I put mine on, but it was easy once you figure out how you are going to access the wiring and connect the correct wires.

I followed the advice posted by T-Mack - FSO in the post referenced at the top of this thread...

Here is what he said...

(I will have my tank off again soon and could shoot you some pics, but don't know if it will be much more help than what has already been posted) Good luck!

The only reason you have to remove the tank is to get at the correct wires. My connection for the pickup is real close to the coil which is right under the tank.

Pretty simple installation. Taking the tank off is really easy too. (remove seat, unhook speedo cable from transmission, unbolt back end of the tank, gently work the tank back and up-especially if you still have a stock petcock and when the tank is loose unhook the 1 wiring connection under the gauges) Keep an eye out for the rubber bumpers that are on the sides of the frame, I had one pop off and roll away without noticing and made reinstallation a trick until I figured out what was missing and found it.

I think mine only had 4 wires too, and I tied the lamp and the ingnition ones together on the power source I found, attached the ground to the frame then the pickup line to the correct side of the coil. Easy-peasy, lemon-squeasy
