1 COYOTE PRODUCTS INC. chassis AND SEAT SETUP sheet 1 Installation instructions are for the following sprint karts used primarily for road course racing not oval racing : FreeRoller, WideTrack, WideTrack LE & FX1. These instructions should be used as a guide to help with the set-up of your new COYOTE Racing chassis . To install your seat in your new kart, bolt the lower seat mount kit to the kart with the sliding seat mount flat tab facing the rear of the kart. Do not tighten, just snug to allow for final adjustment at end of installation. Next install both rear seat struts with flat side of strut toward the center of the kart on both sides.

2 The seat location is determined by locating the engine side seat strut first. Set strut from the outside edge of engine side frame rail to the edge of seat strut at 7 1/2 - 7 3/4 . This dimension will allow all Briggs engines to be run with an inboard clutch and clear the frame at the rear of mount area. We also recommend using our 2 piece angle motor mount with the flat plate containing studs as this is the best possible arrangement for the clutch clearance and engine stability while operating. Lightly snug strut on tube at 7 1/2 - 7 3/4 . Install the other strut between the brake lines.

3 The size of the seat will determine how far to the left the strut will go. Small and Rookie Seats the strut will be just to the inside of the inside brake line. Medium seats the strut will be in the center of both brake lines. Large & XLarge Seats the strut will be as far to the left as possible. Sometimes it will be necessary to bend the left side strut more to the outside off the kart to get enough clearance on the engine. It is not unusual to bend the seat strut to be directly above the main frame rail or even farther on the brake side. Simply tighten the strut to the frame as indicated and use a bar to bend.

4 We use a piece of 1 1/4 square tubing about 3 ft. long, slide over the strut as low as possible and bend as needed to make clearance for the larger seats or you can purchase one of our pre-bent struts designed for this purpose. Medium & small seats will not require this. On some of our different designs the tube the strut attaches to is on a slight angle. Some are forward, some are back and because of this you may need to twist the area of the strut where the bolt goes though. To do this use a 10 crescent wrench and the 1 1/4 bar to adjust as needed. We do not recommend using bolt together struts as we feel these are not rigid enough especially with the larger size seats and today s tires.

5 We also make a 90 degree seat strut which can be used on the brake side frame rail to attach to the seat if the normal one behind the seat won t work. The strut is 8 long. Some of the XXLG seats need this type. In order to get enough engine room the seat must be way over. If you use the 90 degree seat strut on the frame rail it is suggested to buy a pair of seat braces which bolt to the top of the cassettes on both sides and then bolt to the top of the seat for extra support. A 200 lb. driver should use these braces for extra stability to make the seat assembly more rigid which seems to not let the kart stick to the track as much.

6 You will have to custom bend these to your kart and seat. We send these out cut to the correct COYOTE PRODUCTS INC. chassis AND SEAT SETUP sheet 2 length with a hole in each end. You will need hardware to attach them to the kart as well as the seat. When installing the seat remember to keep as close to the ground as practical. We recommend 5/8 - 3/4 at the max from the floor. Recline as much as possible especially adults over 160 lbs. Set back of the seat 14 -14 1/2 from the ground. Do not adjust above 14 1/2 (very important). You will most likely need to cut a slot in the seat where it hits the frame on the left side in order to get the seat under the frame.

7 This is well worth the effort as the lower the center of gravity, the better!! A high center of gravity makes the kart much too unstable and in general creates very poor handling characteristics and will also tend to grip to the track too much. After a slot is cut in seat, place a spacer for the seat back height gauge. Set max height at 14 1/2 from floor. Start by drilling the lower left hand bolt first. Be sure the engine is in place with clutch, pipe etc. This is for 2 or 4 cycle. All cutting to fit should be done before you drill anything. The sliding seat mount can be tipped or slid to properly line up on the seat.

8 Extend the slider back till it touches the seat where you want the seat to be placed, drill this hole. If needed, you can bend the tab on sliding seat mount but that is not usually necessary. If you are using a flat tab seat mount it will need to be twisted as required in order to match up to seat. Once you are sure the seat is far enough left to properly attach to the engine side seat strut and low enough to be on top of spacer on the floor and that the seat back is at 14 plus, drill lower left hole on slider first. Install the bolt supplied with grommet and snug in place lightly.

9 Next drill the seat strut on the engine side. Be certain to level seat on top with a torpedo level to make seat look level after installation. Before drilling strut be sure strut is in the proper location to allow as much clearance for engine as you need. Be certain that the seat back height is in the proper place for the size seat that you are installing. Drill and install the bolt with grommet supplied and lightly snug. Next drill the strut on brake side and install mounting hdwr supplied. Before drilling brake side hole level the top of the seat with a torpedo level. The seat back height has already been determined by the engine side strut.

10 Finally drill the RH lower slider bolt in place. Be certain it is tipped to line up on seat good. Bend if necessary. Now tighten the seat in place, including strut clamps and slider clamps. Be certain when attached, the struts are vertical or lean forward a little as we find the struts last longer if they are. Some seat struts, if not vertical, you should install braces for best results. Be sure the seat you are installing is going to be correct as follows: Medium & Large - 14 min from the floor Small Seats - 12 min from the floor Rookie Seats - 10 min from the floor These dimensions for the seat back heights are set by WKA in their rule book in the chassis section along with nose cone dimensions and fairing size.
