I am a new member, "BSAJUNKIE". I am an old fart, having raced MX in the 70's - proud owner of two vintage CZ 250's and one vintage 370 Bultaco Pursang. Way back when I had a 250cc BSA scrambler and decided to build a newer (1980's) version of a thumper trail bike. Just bought a 1981 Kaw KE rolling chassis from BikeBoneyard (an online salvage yard in MT) and will install a 200cc Honda 4-stroke hot rod engine. While I'm in no physical condition to race, I plan to have one kickass, stripped down, berm busting trail bike. Would love to hear from anyone who has completed a similar project!
