Re: advice for exup valve and flapper mod on cbr 929
backdoc and catch22, thanks a lot for the replies, much appreciated.
Okay, I am now in agreement with you to get the flapper mod done too, and seeing the filter is being replaced, it should be easy enough.
I have read previously about not using k an n, about engines running lean etc., however, I note too that you backdoc use a bmc filter, and not stock. The people I am using for the work are professional tuners, and their tuner is a professional road racer and short circuit, competes in the TT etc., so I am satisfied they know their business. My blade is purely for road use, I would never take it on a track day. Is the k and n really such a bad idea? A new stock filter I think won't be much cheaper, the tuners are the ones who said replace the filter with a k and n.
Thanks for the link to the Leo Vince, but I am not sure they would ship it, and I would be hit by uk customs charging me import
tax on it too. It's a pipewerx end can I am having fitted, they are decent enough exhausts.
I am happy to leave the cabling and servo etc. in, should I wish to change things or go back to stock later, unless they
really will cause trouble being left in situ?
I am hoping for better fuelling and a small power increase after the custom map after dynoing.
