Camshaft Plug Yamaha XS Cylinder 3 Seal Yamaha XS Primary Chain Yamaha XS Clutch Lever Yamaha XS Brake Lever Yamaha XS Fuse Box Yamaha XS Oil Filter Yamaha XS Air Filter Yamaha XS Ignition Coil Yamaha XS Rectifier Regulator Yamaha XS Starter Relay Yamaha XS Fork Seals Yamaha XS Triples seem to perfectly blend the torquey nature of V-Twins with the high-revving excitement of four-cylinders, with a wonderful exhaust melody to boot.

Now Yamaha has released its latest Triple, the FZ, with sights set on grabbing a piece of this three-cylinder pie. The tuning fork company is looking to shake up the relatively bland motorcycle scene coming out of Japan. To fully appreciate the next wave of Japanese Triples, we need to look back at the last time Yamaha had a go with three cylinders.

The origins for these two bikes share a similar plot line with the FZ Inin an attempt to introduce something new, exciting and different in the age of the four-cylinder Kawasaki Z1 and Honda CB, Yamaha introduced the XS The iron block carried a forged steel crank with two-piece connecting rods and plain bearings.

Power was transmitted through a five-speed gearbox and ultimately a shaft drive to the rear wheel. A feature seen on many shaft-driven motorcycles today, CV U-joints allowed the swingarm to pivot up and down without affecting the power delivery to the rear wheel. The XS, while unique among its competition, was engineered with reliability in mind and was never the horsepower king amongst its rivals, especially the Kawasaki Z1.

Ride quality was impressive for its time, and the twin rear shocks featured five-position preload adjustability. The telescopic fork was adjustable three ways. Sounds rather rudimentary today, but by standards the XS handled rather well.

A major issue affecting handling is fork stiction, or the stanchions not compressing or rebounding smoothly after a jolt.

The seemed to solve those issues, providing a surprisingly compliant ride. It, along with the distinctive engine, made the XS a collectible bike today. So in the XS was introduced. Still, it was the bigger Triple people were asking for.

Because of this EPA crackdown for cleaner burning engines, Yamaha turned to Hitachi, not Mikuni, to outfit the XS with carbs jetted incredibly lean. This combined with a very restrictive muffler and complicated air intake plumbing meant the pleased the sniff test, but performance took a dive. A demand for more power spawned the XS Despite the bigger engine, power was actually less than the XS due to the strict emission requirements of the time.

Of course, once the bikes went into private hands, bigger jets or a whole carb swapcleaner intake routing and free-flowing exhausts quickly fixed this power issue and negated any stride to help the environment.

The s continued where the left off, introducing air forks to complement the adjustable shocks. A common feature on some cruiser shocks today, the air forks work in a similar fashion. Increasing or decreasing air pressure within the fork tube helps determine the stiffness of the front end.

The system had its quirks, but overall it delivered a good ride.Do NOT try to measure old rubber. These are long lasting diaphragms made of TSR compound able to run in fuel containing ethanol.

Heat resistant, too! These diaphragms can restore smooth running and original fuel economy to the motorcycle. They give a smooth rolling action to drive the throttle slide.

Takes about 15 minutes to install and that includes taking the photos. Less expensive and easier to install than other types of replacement diaphragms for vintage bikes. Designed to prevent twisting of slide to keep hole and cut-aways aligned.

H is being used on some Keihin carburetors as well. This diaphragm does not come with the slide, as no new slide is needed. All you need to do is to position the slide correctly in your carburetor.
