So I just ordered a set of Bub 2-2 Exhaust for my 08 Bonnie Black and had a few questions about the jetting. Is anyone out there running Bub that can give me an overall starting point for Pilot/Main/shims? I know that each set up can be different but I just want an idea of what I should buy. I called Bub to see if they can give me the factory recommended set up but they told me to ask my dealer. I could have swore that D & D and other companies sent Jet kits with pipes/mufflers. Apparently Bub does not. The bike's stock BTW (performance wise anyway). I appreciate any help/advice that can be given...
I'm sure you will get responses from many who are expert in this field. In the meantime I would check out this info. It will help a lot. You should at least get a good starting point.
you still have the stock airbox in place? I would try 125 mains, leave the needles alone, and you might have to richen the idle screws a bit. With the airbox still in place you shouldn't neet too much more jet.
Enjoy the loudazz Bubs! Go set off some car alarms
I just installed a set too. I ended up getting a dynojet kit, using the supplied needles and the 114 jets, which are about 120 from what I understand. It still is a little rough at 2000rpm, so I'm gonna try messing with the needle height to see if that helps. This is the first time I've ever tried re-jetting so I'm no expert, but it's fun to mess around with.
Oh and I'm running a K&N filter with the airbox still in place.
Thanks for your input guys. I ended up buying an airbox eliminator kit (along with a crap load of other parts from Bella Corse) to go along with the pipes. The jets should come included. If anything else, I'll dabble. I just couldn't find it in myself to only replace pipes and not the airbox...
