trevorb Posted May 1, 2020 Report Share Posted May 1, 2020 Have a look at the LITETEK website....the guys that supply the viton o-ring carb kits from Thailand. There is a tutorial on there to rebuild Mikuni carbs including butterfly shaft removal, its inline 4 but should cross over.... https://www.litetek.co/Guide_MikuniBDST_Rebuild.html Quote Link to comment Share on other sites More sharing options...

alext Posted May 2, 2020 Author Report Share Posted May 2, 2020 well, the simple answer is yes - remove the butterfly and the spindle pulls straight out. currently cleaning it all up and looking for my silicone grease... Alex. Quote Link to comment Share on other sites More sharing options...
