I have a large Clarke tank on my 07 YZF. The stock petcock is facing the wrong direction and forces the gas line to make a big 180 deg loop that could catch on a branch. There is not enough room to flip it around as it will hit the cylinder head. Where is a good source for petcocks? It looks like a stock 03-05 petcock will work OK. I suppose I could order one from Yamaha.Has anyone else encountered this problem?
