"Cubic inch capacity is replaceable with nothing but more cubic inch capacity" This is an old saying, but it's message is still relevant! Especially the torque optimized 660 engines profits a lot from this modification. The power and the torque will rise over the hole range - more power in all situations.You do not have to change any more parts that the piston, cylinder and the gaskets. · drilling / coating of your cylinder · more power over the hole range · due to the high class new Low-Friction coating the new cylinder is even more reliable than the stock one · nobody can see this plus of power on your bike (Police...) · no more noise on the bike · perfect in combination with our racing cam and the cylinder head modification. The new low-friction plating is a extremly high grade plating that works perfectly with all kind of piston rings. The new honing is necessary concerning the correct running clearance and the surface roughness adequately to the piston rings. We do the following on your cylinder · de-monting, cleaning and glass bead blasting · boring of the cylinder up to the needed size · exact honing of the cylinder (cross-grinding!) up to the needed measurement · new coating of the cylinder

High quality manufactured oil bypass valves (thermostats) from JAGG.   An oil thermostat in combination with an efficient oil cooler has immense advantages that lead to an enormous increase in the service life of your engine. The oil flow to the oil cooler is automatically regulated according to temperature. At about 85°C the thermostat starts to regulate from 'Closed' to 'Pass'. From approx. 90°C the complete cross-section to the oil cooler is released. Installation in the two oil lines to and from the oil cooler.   The automatic oil cooler bypass works like a remotely controlled thermostat and directs the oil past the cooler until it has reached operating temperature. Ideal for automatically adjusting the cooling effect of an oil cooler on air-cooled single-cylinder engines.   Dimensions only approx. 38×38×19mm (without connection pipe). Connections 3/8" ~9.5mm Suitable for all OTR oil cooler kits and individual applications

The Jagg Manual By-Pass Valve acts as a manual thermostat, allowing you to by-pass the oil cooling system for cold-weather riding or for faster warm-ups on cool days. Works with most oil coolers. Durable anodized billet aluminum construction. Compact in-line installation.   The Jagg Manual By-Pass is supplied complete with all necessary hardware and easy-to-follow installation instructions. Installation note: If the oil hoses between the oil cooler and the oil source are too short, the oil cooler by-pass valve may not fit in the oil lines. Jagg mini by-pass valves require at least 7.5 cm (3 inches) of straight hose.   Dimensions only approx. 38×38×19mm (without connection piece). Connections 3/8" ~9.5mm Suitable for all OTR and other oil cooler kits as well as for many standard oil coolers

The secret of the new NGK Iridum IX spark plug is the laser-welded electrode made of Iridium. Thanks to her "minimal" diameter of only 0,6mm it concentrates the ignition voltage. This improves the combustion in all drives. Thereby the engine runs absolutely round, the motorbike speeds up faster. The high-tech metal iridium ensures the exact spacing between the electrodes. This prevents ignition misfire. The XT gets a notably softer engine operation, the gas acceptance is improved. Further, the Iridium spark plugs' durability is twice as long as that of "normal" copper spark plugs. Fits all: · Yamaha XT-660 R/X and XT-660Z Tenere.

NGK offer high qulaity spark plugs for the XT660 model range. NGK standard plugs are constructed for longer life and optimum performance. · Trivalent metal plating provides superior anti-corrosion and anti-seizing properties · Corrugated ribs prevent Flashover · Pure alumina silicate ceramic Insulator, provides superior strength and better heat transfer · Copper Core aids in heat removal · Triple seals prevent leakage With a new spark plug, the XT often gets a notably softer engine operation, the gas acceptance is improved. Fits all: · Yamaha XT-660 R/X and XT-660Z Tenere.

Stahlbus Yamaha complete Set for a quick, easy and clean oil change. A conventional oil change is always associated with spills and dirty hands. Therefore, this system has been developed with which you can perform an oil change completely safe and clean. The oil drain valve will easily replace the existing drain screw. When changing the oil, you unscrew the cap and put on the hose connector via quick release. Only when this is locked, the valve opens and the oil can be drained into the provided container.   The advantages at a glance: Easy handling due to quick release Drain valve can not be lost No risk of burns from hot oil Seal change is not necessary Sump thread is spared Double outlet protection (protective cap and valve) Connection to suction possible Optimal application for discharge sampling or trapping Protective cover against loss through O-ring Change oil without tools Thus, the oil change makes fun!

The concept is simple: the more you flow, the more you go. The better you can move air and fuel through the motor, the more power you will produce. To achieve this with an acceptable amount of money we now offer the boring of the throttle body. The whole throttle body will be machined to a +2mm bigger diameter. The axle is flow optimized and a new, special made throttle plate is mounted. This offers a maximum air flow. Horsepower gains up top without losing torque and power down low. An added bonus is that with the +2mm throttle body, the horsepower and torque is held longer in a usable range. What can you expect: up to 1 PS in lower, up to 3 PS in the upper range. This will make your 660 a real beast! We need your throttle body for about 6-14 days here in the workshop, depending on season. Please sent in the throttle body only - without any additional parts like the injector, throttle line bracket, TPS (throttle position sensor), gaskets, springs or any other parts. Only the housing, axle and throttle flap! Fits all: · Yamaha XT-660R · Yamaha XT-660X · Yamaha XT-660Z Tenere · Yamaha XT-660ZA Tenere
