royalista,my sprag went out at 13,000 miles or so also.i determined that the other gears were fine so for me it was a simple matter of cost.bike now has just over 17000 miles. really the only problem ive had was the sprag issue and a flat tire. ive replaced the drive chain and front and rear sprockets,and swingarm bushings,but that was due to "operator failure". no fault of the bike,i just haven't rode in 30 yrs or so,and wouldn't have had the other problems if i had the proper chain tension,leasson learned![i was excited to do a 1000 mile road trip] witch came off ok except the tire issue.i really love this bike and the only thing i would change [beside no kickstarter] is that im thinking of repainting it to the old re color of blue with black frame,that would be sharp!
