Hi am new to brit bikes had a yamaha 650 twin side by nsid many years ago. just finished a EL harley 1940 but sold. I own several FLHTs 2009, 2006, 1998 and 1964 honda super 90, and a few trail 90s I just picked up a 1972 Bonniville V . Working on those AMEL carbs cuz the bike has no pulling power, they were bad. Cant test ride tell spring, any other issues i might look for, got new battery. Bike has set for 23 years.
