I have the t-bags 3-pouch w/s bag & it didn't quite fit w/6.5" Klock Werks shield. Ended up ordering the 8.5" KW shield & sold my 6.5" to another forum member. BTW - the t-bag part# is TB3200WBP & you can order directly from them (Welcome to T-Bags.Com Saddlebags, Luggage, Harley Luggage, Travel Bags, Motorcycle Bags), or I got mine @ Dennis Kirk for $65...good luck!
I had the same issues with my 6.5" KW windshield and sent them an email requesting a list of windshield bags that fit and they have a small bag that fit fine with mine. Kind of pricey but what isn't. This bag is excellent quality and has worked well so far. Go to Kustom Baggers or Google Boss Bag. Would post a link but don't have enough post on this forum. Hope this helps.
