Hi to you all and a very HAPPY NEW YEAR. I own a cbr 954 2003 which by looking at the exhaust it appears to be running rich. My question is with the price of a new fuel pressure reg. is more than double for the VTX1800 and yet they look alike as with the F4i as well. I did see somewhere where a F4i reg was fitted to a 954 with no probs, but according to Honda Aus, they would not list the same item with different numbers, yet for the 954 they list 16740-MCJ-013, which is over $100.00 and the part no. 16740 -MCH-013 is half the price for the VX1800 and the F4i can anybody tell me if I can use one for the VX1800. Cheers and many thanks. Brian.
