i love mine. if you race gusset the frame....do the oil mod..i never have and never had a problem but better safe then sorry. no major issurs. change the oil every two rides and your have a great bike aslong as you take care of it.

no real issues, decomp plug pops out on the older ones that can be fixed for like $12 tho, its all about how the owner cared for it otherwise
