I HAVE RACED THE THUNDERCAT ENGINE IN THE F2 SIDECARS FOR 10-11YEARS TODAY I HAVE COME ACROSS A FUEL INJECTED T REG THUNDERCAT. I WAS AWARE THAT THE BIMOTA SB9I FITTED WITH THE CAT ENGINE HAD FUEL INJECTION BUT NOT AWARE THE PRODUCTION MODEL CAT WAS. CAN ANYONE ADVISE ON TYPE OF INJECTION BODIES (SIZE) IGN SYSTEM, INLET RUBBERS ETC,OR WHERE I CAN OBTAIN PARTS. DOES THE INJECTION T/CAT HAVE A DIFFERENT MODEL ? HAS ANYONE RIDDEN RODE BOTH THE CARB AND THE INJECTION MODELS FOR A COMPARISON. ANY IMFORMATION APPRECIATED.
