I just purchased a 2012 k1600gtl with Hannigan trike kit. It only has 240 miles on it. The dealer I purchased it from had a local mechanic do oil change, drain other fluids and replace, etc. No history, previous owner died after having conversion done, and its been sitting since.
It runs, but has the expected cutout with heavy throttle application. It runs and idles smoothly, until it cuts out. Stay off the throttle heavily and it cruises at 80 just fine. It is included in the fuel pump recall but Bloodworths cannot take me until late June to replace it. Id really like to get it running soon to participate in some rides.
Bought the trike since Penny Moore, my lovely wife, has had back surgery last September and while she loves to ride, she's not comfortable with riding two up on our current k1600gtl 2 wheeler.
