This prevents most of the slipping phase of the clutch, thus creating less friction and allowing less heat to be created. Heat is lost power! Thus your scooter will accelerate much faster due to the power transfer occurring at a lower RPM.\u003c\/p\u003e\n\u003cp\u003eThe clutch can be customized to all personal needs. For example, if you want to get more power at start, choose a stronger clutch spring to increase the starting RPM. If you want to shorten the slipping phase of the clutch, you should use a weaker torque (pillow) spring. For an extreme start, choose a strong clutch spring and a very weak (or no) pillow spring.\u003c\/p\u003e","brand":"HammerHead Performance","offers":[{"title":"Default Title","offer_id":53483531108717,"sku":"169-349_hhpPS","price":289.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1004\/2710\/4621\/files\/img169-349-400.jpg?v=1782374316"},{"product_id":"oko-high-torque-starter-motor-for-150cc-gy6","title":"OKO High-Torque Starter Motor for 150cc, GY6","description":"\u003cp\u003e\u003cimg alt=\"img-qind.JPG\" border=\"0\" src=\"https:\/\/partsforscooters.com\/site2012\/images\/brand-logos\/oko-150.png\" title=\"img-qind.JPG\"\u003e\u003cbr\u003e\u003cbr\u003eOKO High Torque Starter motor for 150cc and 125cc GY6 4-stroke QMJ152\/157 QMI152\/157 engines.  This Starter Motor is recommended for any GY6 with a Big Bore Kit or Stroker Big Bore Kit.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eBolt Hole Spacing: 78mm\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eShaft Length: 18mm\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eShaft Diameter: 11.5mm\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDiameter (near o-ring): 30mm\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eNumber of Splines: 9\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HammerHead Performance","offers":[{"title":"Default Title","offer_id":53483531272557,"sku":"169-491_hhpPS","price":99.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1004\/2710\/4621\/files\/img169-491-400.jpg?v=1782374316"}],"url":"https:\/\/hammerheadperformance.com\/collections\/performance-upgrades.oembed?page=2","provider":"HammerHead Performance","version":"1.0","type":"link"}
