Hello just joined the forum, I picked up an Rt 180 for very cheap, just something to get some dirt experience on. I'm looking for a repair manual..... The bike has a 198cc piston in it, just rebuilt and I'm wondering if I need to do anything to the intake or exhaust to make this a good running reliable bike? Any help or suggestions would be great, I saw someone said to open a choked exhaust, that may help for starters. Mainly I'm wondering if the stock reed valves will be ok.... I've mainly only riden street bikes so not to farmiliar with the dirt 2stroke world!!
