Difference in horsepower specs?

I appreciate all of the input on my question about hp differences,but I really don't need a fuel guage. Mine works great.

Why don't you test your old one and see if it is in fact bad. The spare sending unit I have is round five bolt pattern. I found a brand new one from a distributor last year. It's worth its weight in gold. I have rebuilt them before for my Z1R and my 1300. The four bolt square pattern is the most common and they are easy to find on eBay. I bought two of them for my brothers ZR750 Zephyr about 4 months ago for about $20 each.
