I bought RCComponent 'Nitro' wheels , 838 miles into my New 2009 FLTR.
I didnt get 5 miles down the roads, and got the dreaded 'Wobble', with my hands off the Handlebars!
Took bike in for 1000 mile break in service, and the 'Fallaway' was 6 Schwings!!!
Got it adj. and was good to go for almost xactly 5000 miles!
Then it came back.
Replaced, bottom triple tree plate, 2 winters ago. Bearings were 'SHOT' and couldnt get the bolt that holds them together 'LOOSE'!
bout 9000 miles , after replacing, what I've just stated , havent had any more problems!
Is ur Dealer blowing smoke?,....possibly!
52 lbs. of air in ur Rear Tire? take it down to 40lbs.
I'd lay a $20,00 bill on the Table and say ya aint got nutn wrong w/ur Rims and Tires!
Find the most xperienced mechanic in ur area, and buy him a few,....whateva's! Shoot the Shit and get to know him WELL!!!
