Larger gas tank.

[hawkhan]

I love my hawk, but the only downside is that i hold down my riding crew when i have to stop every 80-100 miles. I can milk the tank out to 120 miles, but why take the risk of running out of gas? I know there is the f2 tank mod, but i am not to turned on about the welding end of the bargain. I remember last year there was a guy who had made a stock tank bigger, but was selling them at a high price. If it comes down to having to use the F2 tank i will, but i was wondering what you hawkers thought about it.

Thank you

I didn't know you had to weld the f2 tank?

[Hawk Jr]

Doc - no weld on the tank - u need to weld the sub-frame

(macfartlane) is the guy was making a larger stock tank at a high price... he's on Speedzilla. Think he was wanting $399 for the tank. U needed to mod ur seat to work with it. He is useing a tank off a Revere which is a european hawk minus the SSSA and moding it to work.

I have seen a few others use different tanks than the F2 but don't know anything about fitting them and what not. I went for the F2 mod and the monster seat.

Paulyboy just did the tank:

I don't know if he needed to do anything special to make it work with the stock seat.

From the other Hawk list:-

The Hawk is severely range-limited by it’s small tank. There are a few options out there for increased range. BD Tech has a kit to adapt an F2 tank fairly simply and these can be picked up used for not much money. At the other end of the spectrum, there are carbon fiber/carbon-kevlar tanks made by Kiyo Watanabe and MotoMorphic. These are beautiful, but pricey. Paul Ritter used to make expanded metal tanks, but has stopped due to an accident. I decided to do the Expanded-Tank method for my Hawk.

After THOROUGHLY cleaning the tank out with non-flammable brake cleaner and electrical contact cleaner, I flushed it with large amounts of water. After air-drying for a few days, I took it to a local fabricator and explained what I wanted and used photos and pictures to make a plan. Basically, the roof was raised about 2” all around. There is a problem area in the front, in that it has to be sectioned back so that the angle to get to the front tank mounting bolt remains the same. He did mention that the metal was thin and warp-prone, but with a little bondo and paint, and a sealing kit from POR-15 on the inside, I had a 4.9 gallon tank.

Another trick I did was to cut a small section of the splash lip near the filler hole – this allows almost a quart or so more to fit in near the top & I haven’t had any overflow problems since.

how much did the last tank mod cost?

[jaysun0ne]

i remeber the cf tanks those used to be sweet
i woulder if you could still get them?

[Hawk Jr]

I think the last new CF one sold last summer... some where in the $800-1000 range... I was told about it when I asked this question last year, he had it up on he web.

Didn't think 1.5-2g was worth it... cash or my wife kicking my ass... even with the killer CF cool factor...

hmmm CF covered F2 tank would look sweet... would match my new CF monster cowl i just bought.

Isn't someone working on a CF monocoque design over in Germany? I bet you could buy one of those for the price of two used Hawks lol
