However if you rejetting with both mod's then i would consider using a 17 in front and a 14 in pilot. That is alittle smaller than my friend went on his when we opened the exhaust up alot and dragons breath intake we went with a 19 and 16. But those number we guesses that turned out to be good.
Thanks brother, that answered my question...at least now I have a starting point to go by....

Live life to the fullest and be careful while doing it!

I have 2000-Vstar 1100 Custom

I just want a simple exhaust change, make stock a bit louder, but dont want to damage engine.

have you had good results from the phelps mod shown below?
What i have read seems positive so far.

http://www.vstar1100.com/jack_phelps/vstar/exhaust.htm

Will the bike work without backfiring and retain AIS?
Any issues with air/fuel ratio changes or overheating of engine/valves. i really dont want to make carb chages and ais changes .

Thanks for your input

Well before I put my V&H slip-ons I had used the mod with the bike for over 3000 miles and I retained the AIS system I had alittle backfiring but overall good sound i only switched because i wanted a different look to the bike.

Default Mod on 2006 1100

I am considering doing the Phelps modification on my 2006. I noticed in the thread there was a specific set of instructions for the 2006 model. However, in the instructions it doesn't describe once the baffle is out if you still place the short piece of pipe into the exhaust. Can someone give me some advice?

Default 2009 1100 Exhaust Mod

It is basically cutting out the baffles. I am thinking about doing this until I can afford real aftermarket pipes and was looking for stories of anyone whom had already done this.

Anyone have experience with doing this mod on a California 2009 1100 Classic? I did the mod on my old 2002 Classic and all went well, but rumor has it there is a catalytic converter in the later model years and I'm not sure what effect the mod would have on the cat, or if there is any difference in the modification procedure itself?

I done this mod to my 06 1100 and my 07 650 without one problem.
the 1100 is at about 28,000miles and the 650 is at about 35,000miles. I removed the AIS from the 1100 but not the 650.
