I just got a Clark 2.7 gal. gas tank and have not put it on yet. I have read a lot of the post and they are very informative. I also did not like my logo so opted to get a plastic tank (black) and I found white vinyl tuning fork logo stickers I think will look cool on it. My question , are the plastic

tanks street legal and will they pass inspection. On the bottom of the tank it says " for off road use

only " Is the Clark Co. just covering its butt or is there a reason the plastic tank is not as safe on the road as a metal tank ?

You have to check your state and local laws, there should be links to the actual statutes on your state's DMV or DOT website.



I know that in NC (where I used to live) there is an explicit requirement that street legal motorcycles have a metal gas tank.



In AZ where I live now, there is no such requirement. It's just different everywhere, so you really have to check for yourself.

I don't see anything in there about metal or plastic gas tanks. Not to mention, your DOT website is a bear!



PLEASE NOTE: I am not a lawyer! Seriously, I have no idea what I'm talking about, but this is what I dug up because I'm bored.

Wow that was detailed.



Quick answer is no its not technically street legal (supposedly because of the expensive testing required) and yes to cover their butts.



No cop is going to look under the tank and you should be just fine. If an inspection is required and it worries you, throw the old tank back on long enough for the inspection.

I am not sure if my Clarke tank is legal here or not.Mine is the clear one and I had it on all last summer with no problems and passed by plenty of cops.I will find out for sure when I get the bike inspected and if it doesn't pass I will install the stock tank long enough to get a sticker.

Speaking of stickers unfortunately vinyl stickers will not stay on the plastic tank long before they begin to bubble.

Here in MA i had an inspection station tell me that a plastic tank was illegal but they were wrong...everything is pretty strict here but if you go to a chopper bike shop to get inspected they don't seem to care much...



(14) Fuel System. Check fuel system and controls and reject motorcycle if:

(a) There is fuel leakage at any point in the system.

(
Any part of fuel hoses are not securely fastened or fuel tank is not securely mounted.

(c) Fuel tank cap is missing or can not be properly secured.

(d) Throttle does not return to idle position when activating force is removed, if so equipped.

(e) Fuel hoses are chafed, cracked, split or swollen or are not a fuel resistant type.

(f) Fuel hoses are routed in proximity to or in contact with high temperature engine parts

Thanks for the input and sticker heads up . I have three sets of stickers one from Yamaha the tuning fork ones on the new T DUBS . I'm thinking now of having my metal tank

professionally sanded and painted and clear coated with the new stock stickers applied over a white circle and using the plastic tank while that is being done and slapping on a set vinyl stickers. What is on your tank in your profile picture ?

you can get stickers to stick to the plastic Clarke tank. It is required to first treat the tank with some heat. Somewhere in the discussions I had read how to do it. As it requires basically melting the outer surface of the tank to 'seal' it' I opted not to do for fear of messing it up. The stickers on my untreated Clarke tank do 'bubble', but have not come off. I did use some alcohol before applying them. Having enough fuel seemed more important than a bike I was gonna worry about every scratch and blemish. Hope this helps. TIM

The stickers on my tank were designed and made for me by MBGraphics, a member on this forum, for a very reasonable price.

I had heard of sealing the tank with heat but opted not to do that for the same reasons stated above.

I may contact MBGraphics to see if some kind of perforated vinyl is available.

Here is a picture of the sticker. You can plainly see the bubbles under the sticker.
