I have a 1990 CB125T (125cc twin used for MSF training) that is the most cold-blooded vehicle I have ever owned. One "feature" about the carbs is that they are the same carbs for this 125 twin and the 250 Rebel, so lots of air for the 125 (or too small for the 250?). Regardless, this thing sucks to ride until it warms up after 10 minutes of riding. And then it's so anemic that Fresh gas, cleaned carbs, good plugs, spotless air cleaners (and no rags in the intakes). Do I go richer or leaner on the pilot or main to get it to warm up faster? Or can I get away with just adjusting the mixture screws? I'm all about experimenting with jetting (lots of two strokes in my life), but these carbs SUCK to remove. It's like they bolt the carbs to the engine before they install the engine. I almost want to pull the head to make it easier to play with the carbs. So I want to make as few internal adjustments as possible. I'll play with the idle mixture screws first, but I don't know if I should go richer or leaner. Thoughts or suggestions?
