find yourself a welder...i have the same bike and the same problem. i do hundreds of miles at a time not fifty squid miles. i drilled out the spots on the top yoke that are actually there for holes for risers..i believe they were cast for several bikes using several bar appĀ“s....hoever i notice alot of flex and head shake with the new set up...thats why im taking my original clip ons to friend who can weld...and weld quite well..were just gonna chop the bar off and add about 3 inches of rise to them...finding a good welder to do this very simple job should be much more affordable then your other options
