I just installed the Clarke 2.8 on my bike this past weekend. Had a few minor issues. When I pulled the petcock (funny word) off it has the reserve which has two pipes going into the tank. My new Clarke tank only had one hole. I had to drill another one to install the petcock. I installed the petcock on the new tank using the original oring and I could not get it to seal. I removed the oring and used the supplied gasket and so far it is holding tight with no leaks after one ride. The other issue I had....I had to shim down the rubber that goes across the frame under the tank to get the tank mounting bolts to line up. Anyone else have these issue with this tank? It is good to go now, but....I did not feel I should have had to do all of this to get this installed.
