I just bought it two weeks ago. I've ridden it for about 4 hrs. Anyhow, today, after I started her up, I noticed some smoke on the right side of the bike, where that chrome steel thing protrudes out and covers some pipe. I noticed that the pipe was burning in two spots. The spots have like a rainbow color to them. Anyhow, some smoke was coming off from there as it was burning so I turned my bike off. However, is this a natural part of breaking in the bike. Is that pipe supposed to be burning like that?
