Went riding this weekend (1st time on bike) and bike ran good. 1. During the ride when I would come to a stop and hold the clutch in the bike would maintain a high RPM and then 10-20 later it would drop down to the normal idle. Any ideas what is causing this? 2. My rear brake line burst/split and I found out while on a very steep hill that I had no rear brake. Does anyone know where I can get a steel braded line? Is this something I can get at a dealer? Thanks!
