My father has a 1999 Valkyrie. Is this an F5 or F6?

I'm looking to get a Valkyrie belt buckle is why I ask....

 

f6 = flat 6 cylinder my father has one too but what the hell do you want a valkrie belt for?

 

x-mas for his pops im sure

 

well if ya'll seem to know about these valkyrie my dad has one too its a 98 and has about 24,000 miles one it. he has a problem with it now, it seems to be dumping gas on the block on the left side of the bike. we emptyed the fule out the tank and put carb cleaner in casuse we was thinkin one of the carbs where sticking. that really didn't seem to help that much but its still leaking. any help would be appreciated. thanks

 

I just acquired a 97 Valk with the same problem of it dumping gas on the block, seemingly out of one of the carbs, did you find a solution, Thanks
