Is there really that much different's between K&N, DNA, BMC. For air flow. And if you was to put one in a zx6 would you have to have the ecu changed?
I would like to know this too... your logic makes sense to me.Ive always wondered if changing the air filter, change the way the ecu set's the fuelling setting's on that bike. but wouldn't that be the case in all bike's if you adding more air you have to add more fuel. so you would have to add a power commander to stop things running lean...
Guys I hope this isn't a total hijack but I have a few questions.
Firstly, I have just fitted a Danmoto Carbon GP exhaust system to my YZFR125, it sounds and looks amazing but it's lost a tiny amount of top end power and backfires like a shotgun! I took it in to Yamaha who said there is NO WAY of adjusting the fueling on the bike except with a power commander / ECU plug in, is this true I thought they could use an FE tool on it?
Secondly, I think an aftermarket air filter will certainly help but am lost as to which one is the forum favourite and am very open to suggestions, bearing in mind the can is a straight through full system and has the connector for the air box hose.
Oh and the videos on YouTube do not give anywhere near the real sound this exhaust makes I think my neighbours sleeping habits are about to change lol
The r125 doesnt have a lambada sensor also as above, the r125 runs a bit rich to begin with, so with an air filter and exhaust it should be fine, my r125 still ran excessively rich after a scorp exhaust and k&n filter. You should be fine mateSo just to clarify... Yamaha CAN adjust the fueling on the bike using a lambda sensor and an FI tool?
Why would they say they can't? Did I just get a slow mechanic?
