I think it hasn't been used for about 15 years, The guy I bought it off said he bought it as a spare
Unfortunately my gamble didn't pay off in hunting for a reasonable condition/priced 43f acerbis tank.
I found this good condition tank advertised for the 2KF in france. I thought 2kf and 43f frames were similar enough and could carry the same tank since Clark tanks are sold to fit 84-89 models...bad assumption. (I forgot US kept 43f up until 89) this tank is just too long for 43f frame, it may fit later models, but thats your gamble to take.
It took a month to get here and cost me about AU$350
Anyway its a great looking tank, and since I cant find a 2KF to buy to put it on(have been looking for 2 years LOL) I am going to sell the tank for best offer near AU$300, or even better I'd love to swap it for a 43f acerbis/clark tank
