I just purchased a 2006 R50X with a little less than 1k miles on it. Even after warm-up, it seems to smoke a little too excessively or at least more than other 2-strokes I've owned over time. When I purchased it from the previous owner and got it home, I was cleaning out the under-seat storage compartment and noticed an unopened TGB check valve. I didn't think much of it at first, but I'm wondering if the previous owner had an issue with it smoking also and maybe ordered the check valve I found. I have not been able to reach the previous owner and was wondering if someone on this forum might could give me some insight.
Thanks!
