Transcription

1 Setting the Wld s Perfmance Standards SLP Single Pipe Set f Arctic Cat 900 Mountain Cat Carb and EFI with Transfer Outlet Tube P.N CP/09-914CP Read instructions carefully and completely befe attempting installation. 1- Remove stock pipe, silencer, Y-pipe and outlet deflect. (Retain stock mounting hardware f pipe installation.) NOTE: This pipe will use the stock Y-pipe. 2- If theres is a diffuser ring in the end of the Y-pipe it will need to be removed. Grind the 4 small welds at the exit end of the Y-pipe and use a hacksaw blade to cut a hizontal line in the ring so it can be removed (see illustration #1). Reinstall the stock Y-pipe. 3- Remove stock silencer bracket from the chaincase (this bracket will not be used in installation). 4- Roll the sled onto its left side place the template provided onto the belly pan to mark the transfer tube outlet hole (see illustration #2). 5- Using a 1 3/4 hole saw drill the transfer tube outlet hole and debur the hole. 6- Install transfer tube outlet plate from the bottom of the sled up. The angle ption of the plate should be on the bottom with the long side toward the front of the sled. Using the plate as a template mark the two holes and drill using a 3/16 drill bit. Rivet the plate into place with 2 steel rivets provided and place rivet washers on the inside of the belly pan. 7- From the spring tab locat hole on the pattern measure 3/4 down the chaincase guard (see illustration #2) Drill a 3/16 hole and rivet the spring tab provided onto the inside of the belly pan with a rivet washer on the inside (the spring tab needs to be pointing up). 8- The center of the raised ption on the OEM outlet plate inside the bellypan will need to be flattened f transfer tube clearance. 9- Run a bead of silicone around the outside edge of the SLP outlet deflect plate and install to belly pan from the bottom of the sled and bolt into place using stock bolts (see illustration ). Using the plate as a guide drill a 3/16 hole in the back of the plate and rivet into place. 10- Install the transfer tube and spring to the spring tab. 11- Remove the stock vibro suppt from the silencer suppt bracket located in front of the chaincase. Install SLP vibro suppt into the large hole in the suppt bracket secure with the 1/4 flat washer, 5/16 flat washer and 1/4 nylock nut. NOTE: The 1/4 flat washer will center the vibro-insulat on the suppt bracket (see Illustration #4). 12- Install spring tab (provided) using the upper rear hole in the chain case that holds the recoil rope guide in place with the spring tab in the 12 o clock position (see Illustration #5). 13- Run a bead of silicone (Permatex 598 Ultra Black) around the bottom edge of the silencer outlet tube (see Illustration #6). Set SLP Silencer into place and bolt to the vibro suppt with flat washer and 1/4 nut. Place one of the stock vibro suppts in the bracket at the rear of the silencer. the rear of the silencer to the spring tab and the bottom front of the silencer to the outlet plate. Optional Deflect Installation: Stock snow deflect can be reinstalled just fward of the exhaust outlet by drilling new holes and riveting into place. 14- Set the SLP single pipe into place. Looking under the pipe, locate the areas around the mag shock tower that are closest to the pipe and silencer. Remove the pipe and cover the shock tower with reflective heat tape in those areas closest to the pipe and silencer. 15- Install SLP single pipe using stock gaskets and springs (on EFI models use grafoil seal provided f sealing pipe to silencer). 1

2 Note: Check tightness of pipe clamps approximately every 100 miles f the first 300 miles then periodically after that. Tension Adjustment: loop adjustment is suggested f proper spring tension to prevent leakage and wear (low tension), allow adequate flex (proper tension) and prevent spring breakage (excessive tension). When system is installed the spring can be judged f proper tension. The winding spacing at the center of the spring will indicate tension. When proper the two center windings will have.040" to.050" clearance between them. This is easily tested with a feeler gage. If tension is increct, the loop on the pipe silencer can be bent in the direction needed to increase decrease tension. Attach a vise grip firmly to the loop and bend. Air Box Recommendation: SLP recommends the use of an SLP High Flow Outside Draw Airbox Conversion Kit. This effectively transfms your stock intake and system will allow me cold air to reach the engine which translates into an increase in hsepower. This system also is less likely to plug when riding in deep snow. Also recommended is the use of SLP Tque Arm #23-57 to harness the tque load and eliminate clutch mis-alignment under acceleration. This reduction of engine movement in the chassis results in optimum clutch efficiency f maximum transfer of hsepower to the ground. Caring f your ceramic coated pipes and/ silencer: Ceramic Coating is an aluminum matrix applied to your exhaust system to provide a thermal barrier f me consistent perfmance. It is a coating which requires little maintenance to keep your pipes and/ silencer looking like new. Upon completion of new installation, wipe the ceramic coated parts of the exhaust system down with brake cleaner. This will prevent oils and grease (usually in the fm of fingerprints) from burning on and staining the exhaust during first initial startup. To maintain your ceramic coated system, wash it with soap and water periodically (especially necessary after trailering it to and from your riding area on roads that have been treated with salt and other ice removing chemicals). Salt and other ice removing chemicals will attack and eat away at the ceramic coating. This will result in rust coming through the coating. Typically you will notice this rusting after your snowmobile has set f a period of time without the exhaust system being brought up to running temperature. Periodically polish your ceramic coated pipes and/ silencer after each washing with an aluminum polish such as Mothers, Maas Blue Magic aluminum polish that can be found at any automotive parts ste. Do not use any acidic cleaners! F stubbn stains use fine 000 steel wool, then use a soft cloth with polish. Failure to maintain your ceramic coated pipes silencer can result in damage to the ceramic coating f which there is no warranty coverage. A little care will insure that your pipes and/ silencer will continue looking like new f many years. Note: In areas of the ceramic coated system where skin temperatures exceed 1300 degrees F, it is nmal f the coating to turn dull gray. These areas should also be washed and polished periodically. 2

The fuel map listed was attained using an Arctic Cat 900 Mountain Cat with SLP Single Pipe and SLP air box. Fuel used was premium 91 octane non oxygenated. SLP recommends that you start at a richer setting than what is listed below and lean down as needed f best perfmance using plug col and piston wash as a guideline. Exhaust temperature gauges can also be used as a tuning aid, but due to differences in gauges, probes, probe position as well as many other engine variables you must first establish a relationship between plug col / piston wash and exhaust gas temperature. Fuel: Minimum 91 octane pump fuel. Fuels containing ethanol oxygen carrying additives will require me fuel than non oxygen carrying fuels.
