Five classic ma­chines brought back to life


1979 Yamaha RD400

We re­built the mo­tor on this RD, while the cus­tomer wanted to do the cos­met­ics. Work in­cluded carb mods, a Zeel­tronic ig­ni­tion con­trol box that works with the orig­i­nal gen­er­a­tor, an ig­ni­tion coil from a TZ250 and mod­i­fied cylin­der heads for mod­ern fuel.

1984 Yamaha FJ1100

Race Tech­niques ported the head, di­alled in cam tim­ing, and Rob did the re-bore. It’s also got XJR carbs, starter mo­tor and ig­ni­tion plus a Stage 3 Dyno­jet kit which helps pro­duce 92 lb.ft and 136bhp. Thun­der­cat front end with R1 fork in­ter­nals fit­ted.

1987 Yamaha TZR250 2MA

Rob Pem­ber­ton’s own sub­tly mod­i­fied F3-spec TZR. All Yamaha parts in­clud­ing race kit pipes and R1ƒZ wheels, and it now has a healthy 58bhp. The Zeel­tronic ig­ni­tion con­trol box al­lows ac­cess to power valve tim­ing where real gains are made.
