I am new to the forums so bear with me. I just bought an 81 honda atc 200. It seems to run descent. It starts on the first pull and idles fine at first until we start riding it a while and then idles high in nutral. If you have an tips or advice pleaseb let me know. It is pull start only, 5 speed, and has the clutchless transmission. I was also wondering if anyone new of an aftermarket axhuast and where I could orderbone from.
