hey guys i have been toying with the idea of replacing my stock 06 tank, the tank is great but just doesnt fit the old school bobber look im going for. have been pricing some tanks online(old sporty and custom bobber tanks) and the prices are outrageous. thought all was lost when i passed a mechanics shop today and noticed an old bike frame sittin out back. called the place and the guy who owned it told me it was as fiberglass tank and i could take it home for fifty bucks. seems like a good deal but im not sure dont know much about fiberglass tanks. any advice is great pros cons etc

i have heard very bad things about fiberglass tanks. they rot from the inside and the resin residue clogs your jets... they develop leaks if they have seams... also, fiberglass will delaminate with too much sun exposure unless the builder used some very specific laminating techniques with UV resin. not worth it in my opinion when you can get a mustang tank or old sporty for about $200.00. (after misc. install parts)

Add to those negatives the fact that it's getting near impossible to find regular gasoline anymore. The 10% Ethanol blend (E10) that replaced MTBE does a real number on fiberglass. Ask all the boat owners who now have to rip out their tanks...
