Coming soon: Performance goods for the biggest singles. We'll mostly be concentrating on the Kawasaki KLR650, the Honda XR650L, and the Suzuki DR650S/SE. Some limited availability of pieces for late ('68-'74) model BSA 500 singles and possibly some bits for the Husqvarna/KTM 690/701. Also, look for a log detailing my attempt(s) to build a five valve ~800cc (to one liter), high compression, possibly liquid cooled, high-revving, single cylinder, sport-touring/supermoto using XT/TT600 and Raptor 660 parts.
