    What gas tank?

    Ineed some help on deciding on a gas tank to switch to. I would like to get a 5 gallon tank, but don't know which tank fits with as little welding as possible. Any help would be greatly appreciated.
    Thanks ,

      Yuppers on the F2 tank... and u can find them pretty cheap on ebay dents or no dents. I got mine w a small dent for $75 shipped. Now I am in the process of grinding and bondoing it up... waiting on my new HVLP spray gun and welder I am getting for Xmas to finish it and add the Monster seat for the look...

      U need to mod the front tab so it goes into the existing mount by adding a inch to the front tab.

      Here is a link to the tank mod:

          I've got an F2 tank on my bike right now:


          Filling it up from sputtering it was just more than 4.3 gallons. That's enough to take me almost 200 miles, so that's pretty damn good. If you need any more, strap a jerry can to the back.

            F2 all the way! I found mine on eBay for $80 w/ a cap/key and the stock petcock.

            FYI: your Hawk gas cap will fit the F2 tank.

                We were goofing around and discovered that not only does a VFR800 tank look cool but it fits surprisingly well on a Hawk! The line almost perfectly matches the Hawk's frame.It's 5+ gallons - way further than I'd want to ride a Hawk.I had an F2 tank on mine but love the skininess of the NT and since I live on a 100mi2 island...having a 100 mile tank range isn't exactly much of a worry-it'd be hard to run out of gas too far from home.not that I've ever run out of gas on a bike ops:

                    F2/3 tanks are all the same.

                    I did not actually mount the VFR tank,just sat it on the Hawk, and it was on a bike with a Hiperform subframe-dunno how it would fit on a stock Hawk. Steve Lenac has a couple VFR750 tanks modded for Hawk that have brackets welded to the rear - don't know the particulars so I'm not especially helpful.

                      I banged up an F2 tank to get it on, but the petcock clearance (with an aftemarket petcock)was the hassle because I fabricated a new seat mount for the project

                          I hear that the later model Harley Davidson petcocks fit. Anyone know?

                          I did the tank conversion on my bike also. The way that I did mine is listed in the following post:

                            I really should have been more dileberate about writing down the part numbers I used, but in truth I would not reccommend my method to anyone as it was not a very good solution. I heard from Alex Carlson that Harley petcocks do fit, and I found that to be true. After the too-be-expected nonsense of dealing with the Harley Boutique shop parts guy, I had a 90 degree petcock in hand. I had brought the tank down there to them, and I ended up with a petcock and some kind of adapter that came with it. It fit, but when I got home I found it was too tall and hit the rear head. I had been to the Harley shop a few times at this point and was resolved to the fact that they were no help, so I had to modify it myself. I placed it in a vice and through a combo of sawsall and a cutting wheel I trimmed the petcock threads down. I cut them about in half actually when all was said and done. I was so relieved when the adapter caught the first thread on my grinding job. I bought a rubber gas resistant washer and put it in there and tightened till I was afraid of damaging the tank bung, and it worked. It wept a bit at first after a ride or two, so I had to snug it just a bit more, but it has held for a year now.

                            I don't think others have had to grind like I did, so I did something wrong or got a less than ideal part. I share this with you only so that if no one shows up here with a definitive answer and you buy a part that is close but not right, that there is a work-around.

                              I'd like to get a 5 gallon tank too, but I don't really like the way some of the tanks don't quite follow the frame rails. Does anyone know if the tanks from the Revere model would follow the rails and if you can still find those tanks anywhere?
