This is a barrell i had in to tune recently that had been steel relined and ports were all over so was left no choice but to go full on with a high end tune on it ,ports hadbeen cut below bdc and other issues which i felt would detract heavily from its final output
it was brought for dyno other week along with the avanti tune and ran up on the dyno with its supplied pipe a race item ex bsso use so expected it to rev some and it didnt dissapoint
results were good and decided to test the pipe on the shootout rb250 motor to find it was 2 bhp down on the franspeed and 3.5 ft lbs down too
so with a franspeed fitted i reckon 40bhp 25tq would be seen ?
60 110 (230cc)
35 mikuni
bsso pipe
rb triple port (linered)
