Hey, So I recenetly got a 1986 Honda XR250R. All I can say is I had quite a lot of work at the shop put into it and it is running amazing. I was so surprised. Anyway. So what gas would you guys recommend putting in it? I was planning on 91. Also how long can that sit? It wont be always staying at my house so I was curious if I were to leave it for 2 or 3 weeks without touching it if that will be fine or if I should drain it. Also, is it true that after riding I should turn the fuel off and run it until it dies? That's what I was told but I never knew if it was actually true. What oil would you guys recommend I use in the bike?Last question, total noob question, there is almost like a little cap at the end of the exhaust. What is that? Am I supposed to leave that on? I mean it's on there tight. I haven't have a good look at it so I cant describe it too well, but Im pretty sure ive seen other bikes with something like it. But of course it's better to be safe then sorry. Thanks to all of you who help.
