    Excelent quality speedy delivery

  2. Malcolm B. (verified owner)

    All products received are very good quality and delivered on time, however paying over £500 for inner and outer primary chaincase I would have expected it to come complete with filler cap !!

  3. Dirtdigger11 (verified owner)

    I purchased the last one in stock 2yrs ago along with the stator adapter ring. All parts & hardware fit perfectly ….but I can’t permanently mount them because Im unable to find the correct rotor & stator to complete my ‘58 6t build
