YAMAHA BANSHEE DRAG RACING HEAVY DUTY CLUTCH KIT!!

YAMAHA BANSHEE ALL YEARS.

THIS KIT IS FOR DRAG RACE ONLY! THE SPRINGS IN THIS KIT ARE TOOMEY STYLE IN STIFFNESS, VERY STIFF AND SHOULD ONLY BE USED FOR DRAG RACING APPLICATIONS. THIS KIT IS DIFFERENT THAN OUR STD BANSHEE KITS BECAUSE OF THE SPRINGS THAT ARE INCLUDED. WE WANTED TO OFFER A KIT STRICTLY FOR THE DRAG BANSHEE. IF YOU TRIED TO USE THESE SPRINGS FOR REGULAR RIDING YOUR CLUTCH HAND WILL NOT LAST LONG PULLING IN THIS CLUTCH TIME AFTER TIME.(REFER TO OUR STD CLUTCH KITS)  

    We have been an ATV dyno tuning facility since 1999. During this time we have logged over 15,000 dyno runs on ATV’s. From the beginning, the most common thing we saw from quad to quad was that the clutch would slip under heavy load. This is instantly noticed when a quad is being dynoed, because the rear of the bike is strapped down to the drums on the dyno so that the tires do not slip and you can register horsepower.

    When the tires are unable to spin freely like they do in the dirt or sand, the entire load of the motor is held solely by the clutch. If it is weak, poor quality or badly worn it will break loose and the motor will rev up and the quad can’t put all the power to the ground.

    We have come up with a clutch kit combination that has worked well over the years and finally are able to have the kits made to our specifications.  

  1.  We use the friction plates out of a 1997 YZF1000 street bike. These friction plates can stand up to high horsepower and are very durable.

  2.   The steel plates are the most important component in the strength and durability of a good quality clutch kit. The steel plates are full plates which give maximum contact area with the friction plates. Our steels are smooth on both sides, most clutch kits have “dimpled” or “textured” steel plates. THESE TYPES OF STEEL PLATES DO NOT LAST AS LONG AND DO NOT HOLD AS MUCH HORSEPOWER AS SMOOTH PLATES. The dimples are concave and decrease surface material and contact area. We have done tests where we had quads that had a slipping clutch(The clutch that was in it was new). We took the “dimpled” steels out and replaced them with smooth steels and the clutch stopped slipping.

3.    Springs are equally important, we use a spring that is 25%- 30% stiffer than stock. This helps with pressure on the friction and steel plates limiting clutch slippage.

Our clutch kits are not the cheapest kits available, but we feel we have created a truly custom high performance kit at a reasonable price.
