Trail Tech Handle Bar, Computer, & Billet Holder Install Guide

Degree of Difficulty: 2

Tools & Parts Needed 1) Ratchet, extensions, & sockets 2) Wrenches 3) Drill 4) Blue Loc-tite 5) (2) Lock Washers 12mm

Step 1  Remove right front wheel, brake caliper, & hub/brake rotor assembly. This does require removing the front axle nut.

Step 2  Replace one of the stock bolts, that hold the rotor to the hub, with the magnetic bolt supplied with the install kit. The original bolt is on with Loc-tite so you may need to heat it a little to loosen it. Set a side for now.

Step 3  In this step you must drill a hole in your spindle. Be careful because you are using a very small drill bit and it can break off in the metal and cause problems. You will need to hold the sensor up to the spindle and mark where the hole needs to be drilled.  Install sensor with self tapping screw supplied. Reinstall hub/brake rotor and brake caliper.

Step 4 At this point you must route the sensor cable. Wrap it back around the top of the brake caliper and then run it along side the hydraulic brake line. It needs to follow the brake line all the way up by the handlebars. Tie strap it to something up top so it does not fall back into the body while you are getting the rest ready.

Step 5  Remove all of the handlebar accessories and handlebars. Including the plastic housing for the key switch and temp light.

Step 6  Remove the stock aluminum handlebar holders. At this point you should be looking at just the top of the steering stem with 2 holes.  Keep track of the bolts because you will need them in a minute or two.

Step 7  Place the plastic key switch/temp light holder into place. And install the switch and light into the holder.

Step 8  Slide the handlebar clamp into the plastic switch/light holder. Using the bolts and flat washers you took out and also add a lock washer and some blue loc-tite, install the clamp. Make sure these bolts are tight and don't forget the Loc-tite and lock washers. They will loosen up if you don't. Trust me, it happened to me and almost ruined my day.

Step 9  Loosen the 4 Allen head bolts, and install the handlebars. After adjusting the bars to your riding comfort, tighten the 4 Allen head bolts. The end of the sensor cable has a square black plastic piece with metal contacts on it. Use the screws provided to attach this to the billet housing. The computer itself simply slides into place and will lock into place with a plastic tab.

Step 10  Now all you have to do is re-install all of your handlebar accessories and your almost done.

Step 10  You have to set up the computer. The instructions will tell you how to set everything up. The most important part is putting in the correct front tire size. The most accurate way to do this is to follow these instruction. Put the quad on your driveway.  With a tire crayon(or similar), put a mark on the bottom of the tire and a mark on the ground adjacent to the tire mark. Then roll the quad forward until the mark on the tire has gone all the way around once. And is back in the original position. Then make another mark on the ground. Take a tape measure and measure between the 2 marks on the ground. In most cases the measurement will be between  20" and 24" depending on the size of the tire.
