Rev limiter

[Brenna1960]

I am going to put the RamAir intake on my 15 X I already have big 4" high flowing Vance & Hines Pro pipe, so basically a stock head pipe straight to the v&h. I am going to use the Doebeck EJK tuner to do away with the O2 sensor. I am having problems with the pipe flowing so much it is bringing in cooler air through and throwing off the computer so I am "hunting" bad at idol.

The guy I talked to at Doebeck seemed very knowledgeable and was willing to help me tune it via phone. So I believe with the better breathing I should be able to get another 800-1000 rpm out of it

The EJK is a good unit. You can go one better with the AFR Plus. I have both and like the AFR Plus much better. It uses the wideband O2 sensor and makes a big difference as to what you can do with the fuel and different intakes and exhausts.

I raised mine to 7000 simply because I don't want the rev limiter kicking in when I'm getting it on. There are those times when you can't help yourself......

mine would only raise to 6800 but i like that (with tuneecu )

That's interesting.
My recent dyno went to 6900 RPM.

maybe the year of bike allows it to go more.

The stock rev limit is 6300. Someone must have changed yours at some point using TuneECU.

Sometimes it seems over too quickly ie hitting the rev limiter but then I've been riding bikes with twice that limit for the past few years.

I've bounced off the rev limiter at 9000 a couple times, she's screaming good at that point.

I took an old friend for a ride who had never been on a bike since her brother's dirt bike as a kid, she started out nervous and fearful, made me drive on side streets at 30 mph first, by the end of the day she was ear to ear grins, I showed her once what it could do, wound out first all the way, hit second and picked the front wheel up a foot, held it almost to redline, then eased it down gently, she was laughing so hard she couldn't breathe, I told her husband she's going to make you buy a bike now, LOL.

Thought I had made that clear - absolutely!
Was commenting on a remark that a stock engine couldn't do that
Best tuner in the NW, Nels Byerasdorf, tuned mine.
