I am considering putting the HD Chrome Nacelle on my 07 Fatboy, but I have HD Street Slammers on the bike and can see that there might be a problem with fit. Since the street slammers come straight-up out of the triple tree, there really is no "riser".Sincepart of the kit is a "riser cover", I'm curious if leaving it off will create anygaps or simply not look right. Has anybody hereattempted to install the nacelle on a bike with this style of handlebars?

 

What dia. are the street slammers ? Are they 1.25 " or 1.5 ". If they are 1.5 " ...you will need to modify the nacelle. If they are 1.25 " then you will be fine.

As for the cover over the top of the nacelle ...go to cyclevisions.com They make a high quality top piece especially for drag bars.
