Hi, Jason for this situation I would call my local dealer or reputable shop's service/parts department and inquire about any possible quick fix, answers, or parts inquiry. If necessary, transport your bike to the dealer or shop and have a professional technician take it for a test drive, if it is in running condition, and give you a written estimate of repairs and answer any specific questions you may have about your issue. Good luck and have a nice day.

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

No it will not. You probably don't NEED to rejet at all. If the manufacturer suggests it for your bike and pipe combination I would follow their advice. If they do not suggest it I would use a dyno to get the best performance from your new setup. Keep in mine your new exhaust only lowers the back pressure. You haven't changed the intake parameters at all as far as airflow. So any additional air going into the cylinders due to your new exhaust will only be because of the reduced volume in the cylinder while the intake valve is open. This is a rather small amount, so don't get all crazy and jump several jet sizes at once.

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

SOURCE: Loud Vance and Hines long shots

Depending on the pipes you purchased, they will be stamped as to whether or not they meet noise requirements. Many if not most aftermarket pipes do not. Sorry.

You have fitted an awful lot of kit and so I would suggest that you take it to a rolling road (Dyno) and get the bike set up properly. It will csot you , but it will be well worth the money.

Hard to start when hot

It sounds like you fuel map is wrong. Motorcycle are extremely sensitive to any changes you make in the intake or exhaust system. Sounds like you need to take your bike and have it put on a dyno to figure out the new map for your fuel. I'm not familiar with the the Vance & Hines fuel pack. Sorry I couldn't be of more help, Good Luck, Steve

Whats the best after market slip on pipe for both power increase and a nice sound...i have been looking at a very reasonably priced Vance and Hines S4 for just $249?

Vance and hines is always a good choice of pipe, the nice thing about vance and hines is that you can back out the hex bolts on the back of the muffler and repack it when it gets old, or unpack it if you want it louader. Makes it quite tunable. I had a vance and hines 4-1 on my CBR 1000 and I was very satified. The price you are mentioned is good too. The V&E I had on my bike had a good sound at idle and rev and sounded awesome when I tached the bike up.

2009 1200 low harley..pipe turns red after 2 min of running

If you did not adjust your EFI (load a different MAP) then you are leaning the bike way out! This is very bad as the bike will often run at an AFR of 14.0+. do not run the bike until you get the fuel adjusted!! You will void the warranty!!!
