If you don’t do things right, the amount of control you have over the bike is lessened. To start off, pull in the clutch, shift into first gear, roll on the throttle a little, and ease out the clutch. You will become familiar with the friction zone (that’s where the clutch begins to take hold and move the bike), and you add a bit more throttle. You don’t want to stall the engine, nor do you want to over-rev it. There’s a sweet spot in there; find it. Shift while traveling in a straight line. Shifting in a curve is not good practice, and something to be avoided. Become familiar with the sound of your engine, so you can tell when you should shift without looking at your instruments. When you downshift to a lower gear, you should (in one swift, smooth movement) be able to squeeze the clutch, rev the engine a little to let it catch the lower gear smoothly, and shift down. When you come to a stop in traffic, leave the bike in first gear with the clutch disengaged (just in case you want to accelerate out of there in a hurry). Who knows what may be coming up behind you. Braking Don’t ever forget: The front brake on your motorcycle can supply as much as 70 percent or more of your stopping power. The single most important thing you can learn about braking is to use that front brake every single time you want to slow down. Turning When you are riding along the road, you lean a motorcycle into a turn. Learning to lean is an essential part of riding a motorcycle. It is a normal function of the bike when you are changing its path of travel – and quite different from turning the steering wheel of your car. To get the motorcycle to lean in a normal turn, press the handlebar in the direction of the turn and maintain slight pressure on that handlebar to take you smoothly through that particular turn. In other words: press right to go right; press left to go left. Your instincts to keep the motorcycle on a smooth path while keeping it from falling over usually take care of this without you even noticing it. (Demonstrate to yourself how a motorcycle moves by pressing a handlebar slightly while traveling in a straight line. The motorcycle will move in the direction of the handlebar you pushed.) • Slow down before you enter the turn; look as far ahead as possible through the turn. • Keep your feet on the pegs, and grip the gas tank with your knees. • Lean with the motorcycle; don’t try to sit perpendicular to the road while the motorcycle is leaning over. • Keep an even throttle through the turn, or even accelerate a little bit. Checking the Bike before the Ride It’s not fun to have things go wrong on a motorcycle, but if you spend a minute before you go off on a ride, you can increase the chances that nothing will.

Remount footpegs/saddlebag hardware over top of brackets A/B. NOTE: Do not attach leveling stand bracket at this time 4) Attach bracket C(right) / D(left) to rear fender sub frame using new bolts provided. (Tourer model only – Saddle bag hardware mounts to the outside of brackets C/D. Brackets C/D mount between chrome side rail and saddlebag hardware.) NOTE: Brackets C/D have welded spacers which attach in toward rear fender 5) Attach top of Bracket E(right) / F(left) to rear of brackets C/D. Brackets E/F mount to the inside of brackets C/D. NOTE: Use ½ inch spacer between brackets E/F and C/D on Tourer model ONLY
6) Attach rear of brackets A/B to TOP of forward hitch arms. Attach bottom to brackets E/F to rear hitch plate. 7) Carefully tighten all bolts at this time ensuring hitch is square with motorcycle. Hitch Bracket Identification Leveling stand screw jack installation 1) Attach leveling stand brackets to brackets A and B 2) Thread right side screw jack into threaded hole on leveling stand bracket attached to bracket A sand adjust leveling jack bolt out. 3) Push motorcycle over from left side until right screw jack is touching floor. 4) Thread left side screw jack into threaded hole on leveling stand bracket attached to bracket B and adjust out until motorcycle will rest upright on both screw jacks. 5) Adjust screw jacks until motorcycle is level. 6) After InstaTrike is attached to or removed from receiver hitch, be sure to remove leveling stands and leveling stand brackets. CAUTION – Use screw jacks to hold motorcycle upright and level ONLY. Do not lift motorcycle with screw jacks. CAUTION – Use care when installing screw jacks. Be certain that motorcycle is always in a stable balanced position.
INSTALLATION OF THE TOW-PAC HITCH CART. 1. Place your motorcycle on a smooth flat surface, like a garage floor, and install leveling stands. Install right leveling stand first. Carefully raise motorcycle off of side stand and install left leveling stand. Caution – Use leveling stands to level motorcycle ONLY. Do not raise motorcycle with stands Caution – Be certain that motorcycle is always in a stable balanced position when installing leveling stands. 2. Assemble the axles, tires and wheels, and fenders onto the tow- pac hitch cart. 3. Carefully align the tow-pac hitch cart’s hitch mount with the receiver hitch on the motorcycle. Now push the hitch mount into the receiver hitch. (this might be a little difficult until you get use to doing it. Removing the paint from the hitch mount and applying a little grease will help.) 4. Place the hitch pin through the receiver hitch and hitch mount ( alignment plate ). Install and tighten the tension bolt

The Rover K-Series engine has now been in production for over 10 years, initially of 1.4 L capacity. Since then 1.1L, 1.6L, 1.8L and 1.8L VVC (Variable Valve Control) have been introduced with an accumulative build of two million engines since 1989. The 1.8L engine is also built under official licence for Lotus and Caterham, and also in the MGF motorsport series. The K-Series is an attractive buy due to its reduced cost and low weight, which is a necessity for sport cars. This report aims to validate Ricardo ENGDYN software with respect to Rover K-Series 1.8 Litre VVC crankshaft durability. The software will be used to output the behaviour of the crankshaft under as realistic conditions as possible. The oil film thickness and bearing load characteristics of the crankshaft through the running range of the engine will be compared to results obtained from in-house software. The torsional and bending vibration output from ENGDYN will then be compared with results obtained from dynamic measurements. Finally, the crank stress and durability results from ENGDYN will be compared to strain gauge measurements at comparative points on the crankshaft. ENGDYN is a computer program used for analysing the dynamics of the engine, and in particular the crankshaft and its interaction with the cylinder block. In this analysis the software will be used to predict the time-domain response of the 3-dimensional vibration of the crankshaft coupled to the block by way of a non-linear oil film. When this loading and motion has been calculated the software can perform a fast Fourier transform to break down the time-domain response into its corresponding frequencies. This allows the results to be post-processed in the frequency domain. 2 Method of Analysis 2.1 Engine Specifications Configuration: in-line 4 Fuel: Gasoline Cylinder bore: 80 mm Piston stroke: 89.3 mm Swept volume: 1.8L Crankpin Peak Power: 107 KW @ 7000 rpm Peak Torque: 174 N/m @ 4500 rpm Engine running range: 750-7200 rpm 2.2 Component Modelling 2.2.1 Crankshaft To perform the analysis within ENGDYN two crankshaft models were created. These included a complete stiffness representation of the crank (excluding the crank nose hub and the flywheel), and a detailed model of the crank from main bearing 4 to main bearing 5, with mesh density increased around the fillets. ENGDYN can however perform crank analysis of any portion of the crank as long as the model incorporates at least two main journal bearings. Features such as bolt holes and oil drilling were omitted on both models, which were meshed using solid tetrahedral elements

1. Make sure your bike is cool and parked on a flat secure surface! 2. Find your battery (you may have to remove your seat or side covers in order to get to your battery) Disconnect the NEGATIVE ( -) cable. Negative battery cable must be disconnected from the battery in order to avoid safety hazards! Be sure as you disconnect the Negative cable that it does not touch or make contact with your Positive terminal 3. Disconnect the fuse holder from the battery – both the positive ( +) and negative ( -) sides. 4. Cut the wire to the light that is not working with the side cutters. 5. At the problem light twist the light case back and forth slowly and then pull firmly, DO NOT yank to remove from the motorcycle. 6. If the motorcycle led light does not come off easily, repeat the twisting motion back and froth until you feel the light loosen – then pull. 7. Pull the motorcycle led light away from the motorcycle slowly until the cut end of wire falls free. 8. If you will NOT be using your motorcycle until the new lights arrive, you may stop at this step. SAFETY POINT: Otherwise, where you cut the wire, you need to dead end or tape the cut wire. This will keep it from shorting out until the new motorcycle led light is installed. 9. Reconnect fuse holder to battery. 10. Reconnect the battery and then install the seat. 11. Return the motorcycle led light or lights to Renegade Lights along with Warranty Return Policy Form. 12. Renegade Lights will return your new motorcycle led lights along with instructions for installing them.
