bmiracle Posted June 27, 2008 Share Posted June 27, 2008 I have a 81' xs 400 and when I let off the throttle at high speeds it tends to let out a single and very loud backfire. This is the only time it really backfires. Is this normal or is there anything that I can do to stop this? Also another question to all those that own similar bikes, this is about gas millage. I get about about 100 miles out of the main tank (not including the reserve), does this seem like what the norm should be for this bike? I seems low for a motorcycle but this is my first motorcycle, so it could just be me being naive about motorcycles. thanks Link to comment Share on other sites More sharing options...

I get less, but i like to ride like i stole it!! Link to comment Share on other sites More sharing options...

When I used to get about 50 I got about 135 miles before reserve. I'm guessing that that's just about what these bikes get these days. I just can't seem to get it better than that, and it's running pretty good now so I think it's about what it's going to get on todays gas (the added ethenol lowers the milage you get).
