I have a 2009 V-Star 950 that I have recently put on a Vance and Hines slip-on muffler. I am getting regular backfiring at deceleration. My dealer/serviceman tells me there is not a AIS on this model of bike for him to remove to eliminate the backfire. Short of installing Power Commander, he said there is nothing he can do. Any suggestions?
SOURCE: Question about Vance and Hines quiet baffles
about 3-5db but you must remember db is not a linear scale but logirythmic. basicallyy the baffles will remove the harsh rasp off the pipe and make them deep in sound, when cold they will be as loud as normal but once they have some heat in them they quieten down

Whenever I have a question about an aftermarket part - I contact the manufacturer, they are very helpful, but to answer your question, In general, if u get the correct part for your model bike, it should mount the same as the OEM part you;re replacing

SOURCE: Which size Jet Kit for 800 Vulcan Classic?
general rule of thumb is to go up about 10 jet sizes,unfortunately it is a bit of trial and error,and you may have to swap out diferrent sizes to get the bike running right,(jets are quite cheap though)but first step about 10 sizes from standard,your local dealer should be able to tell you what jets are in it and supply replacements,if you change to a hgh flow aftermarket air filter you may have to change jet sizes again as changing the filter may effect the mixture ratio in the carbs,,hope this helps
