currently I'm in the process of figuring out my tuning and might be able to use a few tips. I'm trying to track down the cause of sputtery cold starts and trying to rule out the easy fixes first. The bike will sputter and backfire ~1 min into the ride but is usually fine once it warms up. From what at least my common sense tells me is the cold start fuel enrichment might need adjusting - but without anything to compare it to I'm not sure what it needs.. Here's my data:





without knowing what they're supposed to look like I don't really know what to address. If it helps, it's a '00 X1 w. Forcewinder intake and Wileyco pipe.
