Exhaust DB :(

[ghostbiker]

Went to castle combe 2 weeks ago and had my 2004 FZS1000 noise tested with a blueflame twin port on, tried with 1 baffel 109 DB and a fail, tried with both in and hit 106.5 and a fail. (got to be 105 at 3/4 throtle so 9k rpm for the gen 1 )
now it passed with just a single baffel in at brands but they check it at 5-6k rpmso i put on the OE exhaust i kept and tried it again yesterday.
101 db and a pass so at least i can do the castle combe skills day in a few weeks time.

but WOW dose it kill the feel of the bike, its just destroyed the midrange and the top end bhp.
the bike feels so flat and at higher revs feels like the engine is in pain lol
With the full monty and ignition advancer would the bike now be running realy rich as it cant get the power out or is it purely just the exhaust outlet thats strangled
prob gunna leave on the OE for a few weeks as not sure i can be arsed to keep swaping them over but wanna make sure its running as best it can with the oe on.

It's strangled, mostly.  Supply and demand on fuelling.  If it can't flow well enough, it won't pull extra fuel from the carbs, in simple terms.
