One just popped up on ebay... although, from my past experience, you buy it and the vendors says, sorry we can't find it.... but you could get lucky.

so does anyone know if the 2008 Fatbob has a 4" or a 5" speedo, I measured it to be 4" from edge of chrome across gauge to other edge of chrome as seen on bike, but not sure if it's measured 5" under chrome cover???. I think 08 is dif from 09 up..

Any input would be greatly appropriated.

Rick.

I just installed a Baron tach on mine and wasn't too difficult. Just pulled the console to get to the wires and ran one wire down under the frame to get to the coil for an adapter. Pretty easy. About a $220 tach and got off ebay for $100. here are some cell phone pics. http://www.baronscustom.com/catalog/...981/index.html

I assembled the tach and wires first and then installed it on the bike.

You'll need to pull the quick disconnect fuel line off the tank so you can raise the take. Put some paper towels around it when you pull it. It only leaks for a second.

The instructions that come with the tach are confusing. There is a great link here on the site with photo's and more information. Search for it. If you can find the link, you can install the tach.

Looks good. looks identical to mine. But can you please share the info on what wires to tie into? im getting different info on the wiring. I have the black ground going to the battery. Orange going to the power "fuse box" and the pink going to Pin #3 or from what i was told the light green wire with a violet stripe. Are these correct? What did you use? I have power and lighting. But as soon as i turn the ignition on with out starting the bike the tach. needle starts jumping all over the place. I tried to look for A #3 pin number but can not find one.

I’d also like a tach. Been looking at the options to swap the main gauge like the poster above. I’ve not seen that one but there are a few options through the MoCo and aftermarket.
