These sizes were used more often and should provide adequate gear clearance under most circumstances. When in doubt, use a gear from the middle to the small side of the range, because a combination of looser fitting smaller gears will give a harmless clicking sound but to tight can cause a wining sound, binding and premature wear. Consult the factory service manual for information on optimum cam gear to pinion gear fit instructions before you order.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\u003ctr\u003e\n\u003cth\u003eUnit\u003c\/th\u003e\n\u003ctd\u003eKIT\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/table\u003e\u003ch2\u003eFitment\u003c\/h2\u003e\u003cp\u003eL77-84 Shovelhead; 84-89 Evo Big Twin; Conversion kit for 90-99 Evo Big Twin when using custom pre-1990 multiple parts flywheel assemblies (NU)\u003c\/p\u003e\u003ch2\u003ePart numbers\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSupplier SKU\u003c\/th\u003e\n\u003ctd\u003e904148\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer part\u003c\/th\u003e\n\u003ctd\u003e33-4148\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"S\u0026S Cycle","offers":[{"title":"Default Title","offer_id":58631401308504,"sku":"904148","price":185.21,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0975\/8235\/0680\/files\/904148k.jpg?v=1791031332","url":"https:\/\/deathproofcycles.com\/products\/s-s-90-99-b-t-pinion-shaft-gear-conversion-kit-red","provider":"Deathproof Cycles","version":"1.0","type":"link"}
