axulsuv Posted April 26, 2008 Report Share Posted April 26, 2008 Hi ! As I sit here in total boredom (w/a broken clavicle) cause I'm not at the WR in TN. right now , I just happen to have the oe. owners manual for a 74 ty80a handy !!!! the book says Finaldrive 420 chain and 12 /41 or a 3.417 to 1 ratio... And I don't remember how I geared my boys , most likely stock for starters , may have put a 11 tooth countershaft on . But it is a ball to play with , as my shoulder can atest to !!!! Have fun , great little bikes ! Glenn Quote Link to comment Share on other sites More sharing options...
