Well, it's on. Just installed the race kit on my XB9SX. Had the muffler Jet-Hot coated black to match the stock look and everything. The big news is I'm not sure I like the overall performance. Pulls great from 4500rpm and up. Below that it's weak. I ride really tight stuff. I need pull from 3500rpm, 3000rpm would be better. I need to spend more time with the set up but stock pulled better. I hit some 180 degree hairpin turns today. Unless you were "on the pipe" you could give it a fist full of throttle and not much happens. Someone suggested I install a Techclusion and that would fill in some of the bottom end. Any other ideas before I spend $200? | ||

 You know my answer. It's either that or you can try the Drummer... Personally, my low-mid hole with the Race ECM is filled. Could it be better with a different pipe? Perhaps...but you're going to need to balance that desire of yours to keep the noise to a minimum also. The race ECM is designed to add more top-end which, per your description, it does aptly. Ride my bike this weekend and then decide. You'll be able to see if you like it or not with the race ECM, race pipe and Techlusion. If you don't like it, you can always go back to the stock ECM with the race pipe, too. ...or again, there's the drummer! Most of the other exhausts we spoke about are going to be a good deal too loud for what you described you wanted. Chris On Edit: If you decide to go with the drummer, just send the boys your stock muffler. HOWEVER, I get first dibs on buying your jet-hot coated race muffler, OK!?

Hi Chris, I knew I would hear from you. Hope all is well. Spent a good amount of time in PV in the switchbacks. Unless you are in the right gear at the right RPM there is nothing there when you want to hammer out of the turns. Most noticeable when going up the hill in the 2nd turn. The stock ECM may be the answer. Or the stock ECM with a Techclusion. I don't want any more noise that's for sure, I'm not sure how loud the Drummer is. I'll keep you in mind for the muffler if the Drummer turns out to be the way to go. Thanks, E.J. | ||

The Drummer is just a bit louder than the race pipe. I've never had a problem or complaint about mine being too loud. I can send you a .wav file if you email me. Go to http://www.patmedia.net/haynesfam/dynamometercharts.htm to see the dyno charts. The Drummer removes the dip in the torque curve. | ||

 The drummer is no louder than the race pipe, EJ. When I compared them side by side, the drummer was more baratone (deeper) than the race pipe while the latter was more raspy at the higher revs. You don't spend a lot of time on the freeways and you enjoy the twisties, so I totally resonate with your comments. I rode a lightning with the Drummer (on the street)and it was fantastic. No low-mid dip. Might be the way to go for you. 'course I could just send my stock pipe out and have it drummerized also Ride my bike first to see if it meets your needs then decide. Chris | ||

i am new to fuel injection,have xb9sx w/race kit ,race ecm ,race filter. BarkAndBite did you add the techlusion to the race ecm.if so what does the techlusion do? | ||

I've added the TFI to my race ECM. The TFI can add gas based on the position of 4 pots on the device which correspond roughly to main jet, idle jet, accelerator pump and needle on a carb. | ||

The more I ride the bike the more I discover the attributes of it's driveability. It dawned on me it's like it needs an accelerator pump. Around town driveability is fine, in traffic, off lights etc and anything above 4500 rpm is fine. There is just nothing there when you stab the throttle at 3000-4000rpm. Reminds me of a 125cc 2-stroke when you are off the pipe. I also noticed a vibration at 3500rpm on up. I think (hope) it is a harmonic of some sorts produced by the pipe...and not the axle I left loose or something like that, Yikes. Jerseyguy, the only one complaining about the noisy pipe is me. It's loud and I have had a lot of loud bikes in the past. I must be getting old. Had I known then what I know now I would have left the bike stock and just removed the snorkel and added the K&N. It was very relaxed. E. J. | ||

...needs an accelerator pump... And that, my friend, is exactly what the TFI does! Sounds like you already know your next step... Chris | ||

After studying the Drummer dyno charts compared to the Buell stock and race mufflers, the Drummer just may be the ticket. The Drummer appears to work as good or better at all rpms. The race kit muffler mimics stock pretty close up to about 4500rpm, it dosen't feel like it though. E. J. | ||

Just talked to Kevin at KD Fab. Very nice and helpful guy. I think the Drummer is the way to go. He said he can even make it quiet. So I'm going to go find a box to ship my muffler. Chris, you still interested in a Jet-Hot coated race muffler? | ||

I would be very interested in knowing how quiet it will get. I asked Kevin about it a while back. I might be going to the track next year and with the db levels of drummer on my bike I won't pass the tests. A quiet Drummer would be the ticket. I still my stock pipe laying around so keep us posted on how that goes. |
