In a piston valve, the control of stem and seat leakage is obtained by tightness of the valve sealing rings to the body and valve plug. The bonnet compresses the valve sealing rings against the body and the valve plug. Flexible disc springs automatically assure a tight seal by exerting pressure on the valve sealing rings, keeping them compressed. Opening and Closing the TVS Isolation Valves The isolation valve begins to stop flow when the valve plug enters the lower valve sealing ring. When the isolation valve is completely closed, the valve plug is in contact with the full height of the valve sealing rings, ensuring the best possible seal. In fact, there is no advantage to be gained in torqueing the valve closed. Armstrong recommends that after closing the isolation valves completely, the handwheel should be turned back one half turn. This makes it easy to re-open the valve by avoiding metal to metal seizure. Troubleshooting – Isolation Valves A piston valve will retain its leak tightness for several years without maintenance. In severe service, such as rapid heating and cooling, some field maintenance may be required. Depending on the problem, these simple steps may help: ! ! ! ! ! Isolation Valve leaks, when the valve is closed . First, Check to make sure the valve is actually closed . Check to see if bonnet is seated on the body, if not, tighten the bonnet nuts until the bonnet seats. This recompresses the valve sealing rings against the body and the valve plug. If valve continues to leak, replace the isolation valve assembly

Remove tappet assemblies from engine being sure that each one is kept with it’soriginal tappet block. NOTE: This procedure is the preferred method of installation. However, kit can be installed without removing lifters from engine. 2. Remove hydraulic piston retaining wire clip from one assembly at a time. Be careful not to bend wire clip during disassembly. 3. Completely disassemble tappet removing all parts. 4. Thoroughly clean all parts including tappet body. Remove any oil which might prevent hydraulic unit from fully collapsing during adjustment. 5. Insert one spacer from S&S HL 2 Tkit in tappet body. 6. Reassemble tappet in reverse order making sure original parts arereturned to their original positions. See Picture1. 7. Replace wire retaining clip in tappet body. 8. Put tappet back in original tappet block. 9. Repeat Steps 2 through 8 for three remaining tappets. 10. Reassemble engine with modified tappets. 11. Adjust pushrods. NOTE – In all cases engine must be cold and lifter must be at lowest point of travel for pushrod adjustment To prevent accidents, remove ground cable from battery. A. Remove spark plugs. B. Bring piston to TDC on compression stroke in cylinder to be adjusted. Normally both tappets will be at their lowest point of travel. C. Extend pushrod adjustment, collapsing lifter until piston assembly is in contact with HL 2 Tspacer and pushrod is tight. If tappets contain oil, as when pushrods are readjusted after engine has been run, or if all oil was not removed during installation, extend pushrod adjustment until valve is open (about five additional turns of adjusting screw). Allow 5 minutes for hydraulic unit to bleed down. If pushrod can be turned with fingers after bleeding down, lifter is not completely collapsed, and this step must be repeated. NOTE – perform this operation on one cylinder at a time. Do not turn engine until pushrod adjustment is complete. Turning engine while valve is held off the seat could result in valve to valve or valve to piston contact and serious valve train damage. D. Loosen pushrod adjustment until pushrod can be rotated with the fingers with slight drag. NOTE – Shortening adjuster an additional six flats or full turn from zero lash often results in quieter pushrod operation. This provides additional travel for the hydraulic piston assembly, which can improve the ability of the hydraulic unit to maintain zerolash under normal operating conditions. E. Tighten lock nut. F. Follow the same procedure for all four push rods. G. Recheck pushrod adjustment after a few hundred miles. NOTES ● It is a good idea to recheck pushrod adjustment in a new engine as valve train may tighten up due to gasket compression and valve seat wear. ● Upon initial start up after modification, HL 2 Tequipped lifters may be somewhat noisy for 10-20 miles. If lifters are still noisy after 20 miles it is recommended that pushrods be adjusted 1⁄2 turnlooser. See step D

The fitted length of the race springs is the same as the standard spring. 1. The race kit valve springs should be assembled in the same manner as the standard valve springs. Follow the procedure detailed in section 3 of the Daytona 675 service manual. Ensure the springs are installed with the close wound, colour coded end of the springs facing downwards, towards the piston. 2. The race kit camshafts should be assembled in the same manner as the standard camshafts. Follow the procedure detailed in section 3 of the Daytona 675 service manual. 3. The race kit cam sprockets should be mounted and secured to the camshafts using the slotted holes in the sprocket. The slotted holes allow adjustment of the valve timing. The circular holes in the sprockets are for Triumph service tool T3880102 and should not be used to mount the sprockets to the camshafts. NOTE •No timing marks are included on the race sprockets. Race engines will typically have different depths skimmed off the cylinder head and, therefore require specific individual timing. 4. The camshafts should be timed using cam degreeing equipment which typically consists of a degree wheel, pointer, dial indicator and piston stop. Optimum cam timing will depend on the exact specification of the engine, but a recommended starting point is 104o IMOP (Inlet Maximum Opening Point) and 104o EMOP (Exhaust Maximum Opening Point). 5. Always check the inlet and exhaust piston to valve clearance for the timing selected to use, before running the engine. You must ensure both clearances are adequate. As a guide, the standard nominal piston to valve clearance is 1.3mm inlet & 1.5mm exhaust

PRELOAD ADJUSTMENT— On some Works shocks a threaded preload is standard. This allows the adjustment of the ride height of the motorcycle. The preload is changed by turning a threaded nut down towards the spring (higher ride height) or up away from the spring (lower ride height). The nut is a right-hand thread. CHECKING RIDE HEIGHT— 1. With the bike unloaded on the side stand and the shock fully extended, have an assistant measure from a point at the axle (center point) to a point on the frame, fender or bodywork directly above it. Record this measurement. 2. With the bike off the stand and the rider in the seat, bounce on the suspension and let the bike settle. Have the assistant measure from the same two points. Subtract the second measurement from the first.

The flange on the shock bushing must face toward the spacer. The valve should point toward the front of the bike Fig. 1 Top view of upper shock mount. The flange on the shock bushing must face toward the spacer. The valve should point toward the front of the bike 3. The amount of settle, or “sag” is a function of the wheel travel. It should only be between 1/4 and 1/3 of the total travel. 4. If the difference is less than the minimum, reduce the spring preload. Measure the distance again starting with Step 2. Adjust again if necessary. 5. If the difference is more than the maximum, increase the spring preload. Measure the distance again starting with Step 2. Adjust again if necessary. Note: If the ride height is too low, the shock will bottom unnecessarily, resulting in a harsh ride. If the ride height is too high, the shock will “top out” too easily when rebounding from a bump or under hard deceleration. NITROGEN PRESSURES IN EMULSION SHOCKS CAUTION: The pressure in these shocks cannot successfully be checked. Concerns with the gauge volume and the gas volume in the shock body create a situation where you cannot accurately determine what pressure was in the shock. In addition when the pressure is lowered (i.e. checking the pressure) the gas and some of the shock oil escapes into the gauge. It is possible to lose a large percentage of the shock oil by depressing the core of a charged shock to the atmosphere. Please note that in order to check the pressure, some of the gas must escape and fill the gauge assembly. The volume of the gas pocket is about half the size of your thumb, so a very small volume change results in a large pressure drop. Because the gauges’ volumes vary, it is not possible to deduce the actual pressure in the shock prior to attaching the gauge. Therefore it is imperative that any attempt to check pressure be accompanied by the capability of refilling the shock. In other words: If you don’t have a nitrogen source handy, don’t check the pressure! PRESSURIZING EMULSION SHOCKS The pressure setting for Works gas shocks is 250 p.s.i. of dry nitrogen. To pressurize a shock with some residual pressure in it, bring the gauge manifold up to 250 p.s.i. and depress the core with the T-handle. This will either equalize the pressure or refill the shock without transferring oil from the shock into the gauge assembly. The best gauges for this purpose screw on to the valve and incorporate a T-handled core depressor to isolate the shock from the gauge. This allows a leak-free separation once the desired pressure is reached. For simplified operation, an extra valve is provided for the filling apparatus, allowing pressure adjustment with the gauge in place. Works offers a suitable gauge and filling manifold. Most motorcycle shops that deal with dirt bikes can pressurize the shock

1. The Float The float bowl acts as a fuel reservoir to meet engine demand. The float is hinged on a pin in the float boss. It rises and falls with the fuel level in the float bowl. The small metal tang integrated in the plastic float supports the float valve, also known as the float needle. As the fuel in the float bowl rises, the float valve is pushed into the valve seat, until it’s high enough to shut off the fuel flow to the bowl. As fuel is used the level in the bowl drops lowering the float which pulls the float valve from its seat, and fills again. Adjusting the height of the float has a big effect on the mixture as a low or high float level makes it harder or easier for the vacuum to suck fuel into the venturi. Differing float levels cause an imbalance which may be perceived as vibration. 2. The Choke This system is referred to as the choke. But that’s a misnomer. When you pull the choke knob, what you’re doing is retracting a plunger that opens a tube connected to the starter jet, allowing additional fuel to enter the venturi just below the vacuum hose nipple. It supplements the pilot system at start up. 3. The Pilot System The primary purpose of the pilot system is to supply the mixture at idle. It continues to supply fuel throughout the entire throttle range, but after about 1/8 throttle is reached the main system starts to put out more of the total mixture, up to full throttle. By adjusting the idle with the big screw on the left side of the carburettors the position of the butterfly is altered, so exposing one or more of the four small holes that are drilled into the venturi, (leading to the pilot jet) just under the butterfly valve, letting more or less air pass the butterfly. Adjusting the pilot screw that’s under the carburettor varies the amount of air premixing with the fuel before it enters the venturi. 4. The Main System Open the throttle and the cable that’s connected to the butterfly valve turns it from vertical to horizontal, so letting more air through the venturi. This increases the vacuum effect that is transferred up through the vacuum drilling in the slide to the diaphragm valve that leads to the diaphragm chamber. The top chamber is separated from the bottom by a rubber diaphragm. The bottom chamber is open to atmospheric pressure from the airbox. When the vacuum in the top chamber rises enough, the constant ambient pressure of the lower chamber helps the diaphragm valve overcome the downward force of the diaphragm spring, so it rises from the ven- turi. As the diaphragm is raised the needle is pulled out of the needle jet, exposing a thinner portion of the needle taper which allows more fuel to rise into the venturi to meet the increased engine demand. The key parts of the main system are shown in the photo below
