A guide on how to change the oil on a Yamaha V-Star 1100

 

There are 11 steps you should follow in order to change your oil..

Step1

Make sure your motorcycle is in gear. Take a piece of wood and place it under your kick stand to level out your motorcycle.

Step2

Locate and loosen the oil drain plug. loosen the two bolts/nuts holding the exhaust pipe to the manifold. Do not remove them completely.

Step3

Take block of wood out from under the stand and put the motorcycle in neutral. Start engine until it is warm but not too hot. Then turn off engine.

Step4

Place motorcycle back in gear and place wood understand. Slide a shallow pan under the engine and unscrew drain plug to drain oil.

Step5

Remove the two bolts holding mufflers to the frame. Next, loosen the clamps holding the front pipes to the mufflers and remove the bolt holding the rear brake reservoir.

Step6

Remove the two nuts on the forward exhaust pipe flange and remove front exhaust pipe.

Step7

Loosen the five case screws holding the filter cover on. Take filter hatch plug and remove it by wiggling it back and forth.

Step8

Reinstall all parts in reverse order.

Step9

Unscrew oil filler cap and insert funnel into hole. Fill engine with oil.

Step10

Start motorcycle and warm engine to full operating temperature. Check to make sure there are no leaks.

Step11

Shut down engine and check oil by looking at the oil level in glass on the left-hand side of the motorcycle.

Yamaha clinch the title of the Le Mans Motorcycle Marathon

Yamaha Superhero Concept Superbike

Superhero Concept Superbike from Yamaha

This is the Yamaha Tesseract “motorcycle” concept for the Tokyo Motor Show. Featuring 4 wheels for enhanced stability, the frame is apparently still not much bigger than a normal bike. But it looks eye-catching - like something out of an anime movie.

The design fits two different engines, one gasoline of undisclosed size and another electrical. I’d love to see this on the street!

R1 Superbike from Yamaha

Vroom..vroom..vroom..prepare to be blown away with this superb superbike

When Yamaha first introduced its radical R1 in the late 1990s, it was described as a "no compromises", high-performance sportbike. Yamaha has tried hard to stay ahead of the competition ever since. For 2007, Yamaha has yet another generation of R1 to introduce to sportbike enthusiasts.

At first glance, the styling appears to be a mild evolution over last year's popular machine, but Yamaha had more than a new look in mind with the new R1's bodywork. Yamaha claims that the new R1 will have improved aerodynamics and intake flow into the ram-air system. Additionally, a layered cowling is designed to draw hot air away from the engine compartment to help maintain maximum horsepower.

The biggest changes lie beneath the surface of the new R1. The new engine switches to four-valve heads (from Yamaha's trademark five-valve design), features a higher compression ratio (12.7 to 1), and titanium intake valves. The trickest part of the new engine is in the intake, however.

The new fuel injection system features what Yamaha calls "YCC-I" (Yamaha Chip Controlled-Intake). The intake runners measure 140mm at lower rpm levels -- switching to 65mm at higher rpm levels. This spreads torque and horsepower over a broader range than fixed-length runners.

For 2007, the R1 also gets throttle-by-wire similar to the system found on the R6 last year. The powerful chip reads throttle position changes every 1000th of a second. The new R1 will also come with a stock ramp-type slipper clutch for smoother downshifts and corner entry. Radiator capacity is up by 13%, and the exhaust system (titanium, except for a stainless mid-pipe and catalyst) is redesigned for 2007.

Net effect of these engine changes (and others we will discuss after we test the bike) is a claimed increase in power across the board (low-end, mid-range and top-end power). Peak power is said to increase by 5hp to 178hp at the crank.

Consistent with the "all-new" theme is a new frame (flex-tuned for better handling and traction). The rigidity of the all-new swingarm is also tuned (30% stiffer torsionally and slightly less stiff laterally). With a swingarm pivot position 3mm higher than last year's model, Yamaha claims improved turn-in, together with improved traction for corner exits. New 43mm forks feature larger pistons (up from 20mm to 24) and slightly reduced weight. Yamaha claims their rigidity is matched to the new frame for improved performance.

The rear shock features new linkage to change the progressive nature of the damping (again, to aid traction while exiting corners on the throttle).

The front brakes are new, 6-piston calipers using smaller (310mm) rotors. Yamaha claims the new calipers grip the disc closer to its circumference -- effectively making the braking surface as large as the old system, which featured larger, heavier rotors.

The new R1 will be available in the U.S. from November, 2006 at a suggested price of $11,599 for the Team Yamaha Blue color scheme or $11,699 for Charcoal Silver or Candy Red. For additional details and specifications, visit the Yamaha web site here.
