Yeah at the time of building, it seemed to be a great idea, a "hey! I can adjust how firm it is!" but I do hate them too, they constantly leak leaving me with a very soft front.
I think my tank is a 750A tank, but not entirely sure. I picked it up off ebay and just fell in love with the sharp lines.
Found out last week that I have only been running on 2 cylinders! #3,4. So I'm going to pull the spare motor I have and rebuild the head. Figure I'll just use that engine because it has about 25,000 less miles on it.
I'll post some new pictures of my progress on this bike soon.
