#255262 lemual (User) Junior Boarder Posts: 111 Jetting and MPG 2 Years, 3 Months ago   I bought a midnight star on ebay. I found photos of the bike with short drag exhaust pipes. The bike now has the stock exhaust. Today I rode the bike and used up a whole tank of fuel going only about 60 miles. Since the stock exhaust has been put back on do I need a rejet to get the MPGs back to normal? I also believe the bike came from California and may have had the emission controls removed. How can I get the mpg back up to normal? I love the bike, but need to be ready for spring time.   Logged     The administrator has disabled public write access. #255263 Musky (User) Platinum Boarder Posts: 15137 Re:Jetting and MPG 2 Years, 3 Months ago   I just want to be sure. You went through 5 gallons of gas in 60 miles?   Logged       The administrator has disabled public write access. #255264 BigBoyinMS (User) I'm satisfied never being satisfied. Platinum Boarder Posts: 1705 Re:Jetting and MPG 2 Years, 3 Months ago   Does it have the stock airbox or an aftermarket? You're going to have to find out what jet and needle are in the carb also. More than likely it was rejetted much too rich if it had aftermarket pipes on it. Most people do that even though it isn't needed if only the pipes are changed. But to answer your question... it's very possible.   Logged     Last Edit: 2010/02/06 20:10 By BigBoyinMS.   2006 Midnight   The administrator has disabled public write access. #255269 lemual (User) Junior Boarder Posts: 111 Re:Jetting and MPG 2 Years, 3 Months ago   I didn't fill the tank back up, but did look in and it was way down. The gauge showed empty. I guess I used about 4 gallons. It started to rain so I didn't fill up to look. At first I thought it was a fuel gauge problem, but it wasn't.   Logged     The administrator has disabled public write access. #255271 lemual (User) Junior Boarder Posts: 111 Re:Jetting and MPG 2 Years, 3 Months ago   I used about 4 gallons. On the return ride home I noticed the fuel gauge indicated empty. It started to rain so I didn't fill up. I looked in the tank and it was way down. I figure I used 4 gallons.   Logged     The administrator has disabled public write access. #255279 Musky (User) Platinum Boarder Posts: 15137 Re:Jetting and MPG 2 Years, 3 Months ago   You need to base your mpg on actual gas used. The tank still has almost a gallon in it when the needle hits empty. And you need to know how much gas you started with. Look at the float bowl on the carb. See if the Phillips screws that hold it on are messed up. They are really soft and if anyone has messed with the jetting the screws will show it. Or they might have been replaced with allen head screws.   Logged       The administrator has disabled public write access. #255285 lemual (User) Junior Boarder Posts: 111 Re:Jetting and MPG 2 Years, 3 Months ago   Thanks. I filled the bike about an hour earlier. I will fill the tank again once it stops raining. I will be back. I will take a close look at the carb.   Logged     The administrator has disabled public write access. #255288 Musky (User) Platinum Boarder Posts: 15137 Re:Jetting and MPG 2 Years, 3 Months ago   A lot of people jet for just pipes which you don't need to do if you leave the air box stock. And if they follow the jetting directions that comes with pipes they end up too rich. Or they take it to a shop and them put the pipes on. Shops love to get extra money for telling people they have to jet with just pipes. And they almost always jet way too rich.   Logged       The administrator has disabled public write access. #255296 jbiv (User) Junior Boarder Posts: 152 Re:Jetting and MPG 2 Years, 3 Months ago   To get quick and better accuracy ride till you hit reserve. Preferably not going 70 on the interstate but just cruising around 45 or so. As soon as it hit's reserve hit a gas station and put one gallon in the tank. Run till she hits reserve again and that will give you a a good ballpark MPG without having to ride through the whole tank. Besides, some people's version of filling a tank is different from others so you could have a little more or a little less than what the tank actually holds.   Logged     2007 Roadstar all factory   The administrator has disabled public write access. #255298 lemual (User) Junior Boarder Posts: 111 Re:Jetting and MPG 2 Years, 3 Months ago   I've only had the bike for a few days. I filled the tank to the bottom of the filler tube. The bike has custom paint so I don't want any overflow getting on the tank. I have to admit I ran up to 80 and 90 mph while riding. Since I'm a new owner I'm glad I found this forum. I rode a vstar 650 for three years and finally move to a bigger bike, what a difference!   Logged     The administrator has disabled public write access.
