BSA 1971 BSA THUNDERBOLT. THIS BIKE ALWAYS RAN SO SMOOTH. IT BROKE DOWN IN 2011 AND I HAD A NEW TOP END DONE AND A NEW CLUTCH ADDED.$2502.82 SPENT, HEN I ADDED 2 NEW DUNLAP TIRES. NICE AND GUMMY. THEYCOST ALMOST $300. GOT THE BIKE BACK FROM HERMY'S IN 2013 AND IT RANBETTER THEN EVER. THEN IN 2014 SHE THREW A ROD AND YOU CAN SEE THEWHOLE IN THE CRANK CASE. SO IF YOU HAVE A CRANK CASE AND WANT A BRAND NEW TOP END AND CLUTCH WITH LESS THAN 900 MILES ON IT, HIS IS THE BIKE FOR YOU. ALL THE ELECTRICS WORK GREAT AND SHE'S JUST SITTING THERE COLLECTING DUST. I HOPE SOMEONE CAN GIVE HER A GOOD HOME AND USE ALL THE GOOD PARTS. I'VE HAD MANY BRITISH BIKES OVER THE YEARS ANDTHIS ONE WAS ALWAYS THE SMOOTHEST RUNNER. GOOD LUCK IN YOUR BIDDING. I HAVE A CLEAN TITLE IN PENNSYLVANIA.
