At this point, the only way is to go easy on that right wrist. My shift points were 25 MPH, 40, 55 and 65, which once I got my tach installed turned out to be around 4000 RPM. I tried to knock 5-10 MPH off each shift point, but the...

Hey, thanks for the advice. I am guessing since I can't get anyone to swap their stock windshield for my memphis fats, I am getting ready to cut it down and get some lowers mounts and make me some larger longer lowers to cut the wind.

V-twins and carbs don't lend themselves to 'good' gas mileage. I think 36-38 mpg is the expected average. The best way to improve your MPG's:

- cut wind resistance
- slow down to 55-60 mph
- properly inflated tires

Mine were dark BEFORE I installed V&H, perfect afterwards. If you're running rich WITH V&H, then the previous owner rejetted too rich and you'll have to address that. Enough speculation, though. Go yank them suckers out!

Well if mine are dark like yours...what are you doing about it. Tuning or what?

You and I are in the same boat. V&H, K&N, no rejet, 35 MPG. Check your spark plugs. I bet they're perfectly cocoa brown just like mine. If so, you don't have to rejet. If you're running lean, they'll look bone white and you'll see a lot of wear on the contacts.

Mthiele,

I don't know if rejetting has an impact on the gas mileage. I know mine went down after installing a jet kit and V&H, but that was because I was 'blipping' the gas more often.

It sounds like somebody already killed your gas mileage, with gutted mufflers mine was getting 40+ mpg. I just put stocks on and haven't had a chance to to check the mileage yet but when I had the carbs readjusted they told me that they were out of sync and about one turn off. I figure my mileage will improve. When they adjust them they have to do it with sensor probe in both mufflers or it won't be right.

All stock except for K&N air filter. 40mpg.

A proper jetting shouldn't kill you gas mileage. It could actually improve it. By proper I mean with dyno and exhaust gas analyzer.

Hey guys I am finally having time to post up my questions about my Tourer. I have the V&H on my bike and haven't rejetted. I am afraid that rejetting the bike will only ruin my mpg. I really don't want to loose my milelage so I am wondering what effect does the rejetting do to the fuel mileage. Also, if you can list your exhaust and carb set up...either jetted or non with your mileage so I can compare. Right now I am getting 35 mpg. Thanks alot and hope to hear alot of ideas and...
