I think its going to have to be under the fuel tank. Its very pressed for room though. I wonder what happens when I get the IMS 3.0 Gas tank? Does it take up even more space? Under the fuel tanks looks like the best sugestion, alternatively I could check UNDER the airbox. I dont want to put it inside as someone else said, the bike is already choked up, dont want to block the inlet with a big tracker.

I think its going to be very hard to fit it under the tank though. Might have to reroute some things. I took off the pair valve today to make more space, so maybe its possible now.

I dont want it under the seat, because when my bike was stolen last, they had taken off the seat. I am not reall worried about them stripping it any further, because most thefts here are for joyrides and then dumping the bike once its ruined. They dont even care about stripping them.

 

What is the size of a medium-sized phone? This is too big. You might as well consider a small GPS, they are easier to hide, and you can choose products with different prices and features according to your needs. I have installed two types of GPS on my two motorcycles, Spytec and AMERICALOC, and so far, they have all worked well.

Hmm, how about a 12 ga. shotgun shell mounted vertical in airbox under seat. Rig up a remote control spring loaded firing pin so you could blow their ***** off!!! Just kidding...

If you remove some of the desmog tubing under tank, cap off where tubing attaches to motor, you may free up enough room to fit up under tank.

Do you have an aftermarket skid plate like a Ricochet? It would easily fit on top of skid plate and be well hidden, Maybe find a nice sized plastic waterproof housing to put GPS in.
