Impressions,
I've not got much to weigh it up aganst cos I did it all at once (pred pipes, K&N's, secondary removal andre-map)
but it is really easy to remove the secondaries, just the 6 screws that the other posts state and it's done, only problem I had was 1 of the screws was "awkward" initially and that's why the plates moved.
the power is now all through the rev range, I upped the limiter to 7k rpm (just because I could) the bike is a bit greedier than it was before but hey, I'm a rich student pensioner I can afford 18 - 20p per mile approx. :shock:
I found that because the power was all through the range and she was sounding so **** lovely that I was running lower gears than I used to, so I'm consciously keeping her lower now which isn't spoiling the fun at all :twisted:
the conversion was simple using Miami's how-to (cheers Miami)
so, for me, the mods are well worth it, and I'm sure all others agree also.
