Hi all, have 2008 road glide no issues until now. Was out for a ride on the I95. As I shifted into 5th gear I noticed the bike had no pickup but was still cruising. After a few seconds bike just started to slow down. Downshifting/Upshifting had no effect. I coasted off at the exit and stopped the bike. Put bike in neutral and back in first, bike just revs but want move no matter what gear it is in. Anyone encountered this or have idea where to start. I have been running homemade exhaust for about a mouth could this have damaged the engine?
