Gene1020 Posted July 1, 2008 #1 Posted July 1, 2008 HI everyone, I'm about to put Bub 4-2 exhausts(full system, not slip ons) on my '06 RSTD. Has anyone done this? Did you have to rejet? If so, where did you get your jet kit? I can't find jet kits for this bike anywhere. I have already put K&N filters on it. Any help would be great.
Gene1020 Posted July 2, 2008 Author #2 Posted July 2, 2008 Does anyone know where to find jet kits for a 2006 RSTD?
bobbyduck Posted July 3, 2008 #3 Posted July 3, 2008 I added Bub Sleepers, K&Ns, and a Dyna ignition module. I had read here on this site that with these mods, no rejetting is required but I was skeptical so I had a local tuner play with it on his dyno. He agreed it was fine and suggested no changes except to the size of my wallet! I have since put over 13000 km on, about 7000 km pulling a 500+ pound camper trailer with my wife and I bothe aboard, on 87 octane gas with no problems whatsoever. Spark plugs were done about 1000 km ago, nice light brown, even colour, just like it ought to be. I'd just stick them on and run it!
bobbyduck Posted July 3, 2008 #4 Posted July 3, 2008 I just noticed you have the full BUB headers, not slip-ons. I don't know about that. There is a good article on rejetting at http://www.venturerider.org/forum/showthread.php?t=502 Good Luck!!!!
spyderhead Posted July 4, 2008 #5 Posted July 4, 2008 I am putting Bub slip ons, K&N filters this week (2005 Tour Deluxe). Did your changes hurt or help your gas mileage?
FuzzyRSTD Posted July 4, 2008 #6 Posted July 4, 2008 I am putting Bub slip ons, K&N filters this week (2005 Tour Deluxe). Did your changes hurt or help your gas mileage? 2007 RSTD - K&N filters - Roadhouse slip on pipes - 44 mpg after pipes, 38 mpg before pipes. Very criticaly checked mileage. I also plugged off AIS sytem and had carbs synced ($20.00 at dealers- Jefferson City,Ky-Boone the mechanic. ). I think it is very important to have carbs synced after the pipes and filters, this changes your air flow on your bike and thus requires syncing carbs. My bike had a small surge at around 60 mile an hour and was not getting a good gas mileage, synced carbs because of the excellant advise of these fine folks and FIXED MY BIKE:cool10:. Thanks to everyone and VentureRider.Org........... Just my opinion.
spyderhead Posted July 4, 2008 #7 Posted July 4, 2008 Thanks for the advice on having the carbs synched. The bike is due for a 16K checkup/service in a couple weeks, so they can just do it then. Thanks again.

Baseline hp & torque numbers? After the mods? Inquiring minds want to know...
Reshired Posted July 7, 2008 #9 Posted July 7, 2008 I have heard that jetting is needed if you install the bub complete system, but not with just slip ons. Here is a site to buy parts if that is what the OP is asking for. http://www.motorcyclecarbs.com/Mikuni_Carburetors_and_Parts_C6.cfm
bobbyduck Posted July 7, 2008 #10 Posted July 7, 2008 Sooooo..... what are the numbers? Any performance increase? Baseline hp & torque numbers? After the mods? Inquiring minds want to know... If I remember right, 73 HP at the rear wheel stock, 74 HP with mods....torque I can't recall but very little change as well. Seat-of-the-pants says it works a bit better but since it also sounds faster it's hard to really say for sure. I think if I did it again I'd just put the slip-ons for the sound and leave it at that....
Gene1020 Posted July 8, 2008 Author #11 Posted July 8, 2008 Thanks guys, I'm going to install my exhaust today, then have the dealer check the carbs to see if they need to be changed any.

I think if I did it again I'd just put the slip-ons for the sound and leave it at that.... My bone stock 05 RSTD turned 75 HP and 75 FT-LBS on the dyno.
Gene1020 Posted July 9, 2008 Author #13 Posted July 9, 2008 Well I got the exhaust on today, haven't got the carb's checked out yet, but had to go for a short ride. It sounds great and felt like it ran better than before, time will tell on performance and gas milage.
bobbyduck Posted July 9, 2008 #14 Posted July 9, 2008 My bone stock 05 RSTD turned 75 HP and 75 FT-LBS on the dyno. (tsigwing from Texas) Sounds similar....Calgary is at 3500 feet so a short drop from 75 to 72/73-ish would be about right. I guess. That's about what BUB's dyno chart shows - the one that compares their header system to stock....
