Old question

I have an 08 Uly with Drummer and EBR box. Love the bike but would like to correct the flat spot (3 to 4.5k rpm)..Any ideas? Not doing well with the search.

An aftermarket exhaust coupled with proprietary fuel remapping has solved the issue for many.

Re-read your post. Observed that you have both as stated. Hmmmm.... Know anyone that has a dyno?

the race mapping doesn't always agree with the exhaust pipe used, unless your ebr ecm was tuned for the drummer pipe. even then there are a lot of things to consider like altitude & climate.

I live in the SF bay area and would be happy to have the bike dynoed . Any suggestions on a shop?

I had good results with brisk spark plugs
Even customs mapping didn't help in the 1st place 100%

bay: NGK iridium tipped plugs # DCPR9EIX which is stock heat range....and installation of ecm spy race maps cured all the fueling problems on my 2007 Uly including the surging and leanness between 3000-4000 rpm range.

Good advise coming from a 4 and 5 star general. Just remembered RC cycle in Hayward that did a good dyno on a Harley I had. Sonoma looks good but a bit of a trip, By the way is that Fireman Jim?

JTS is fireman jim.

 

[baybueller]

Thanks. Looks like a road trip.

Talked to RC cycles and they sent me to JTS.
