what do you rev to?

standard rev limeter is spark cut at 6300, and fuel cut at 6500 rpm (as stated in original rs work shop maunal)

small resistor on the board controlls the rev limeter, and i believe it can be adjusted in 100 rpm incrememnts,

jamsport posted the cose of the standard resisitor once, so you can check,

cvh bottom end pretty tough though, 7000rpm is ok as long as its not every single gear chang
