I have a new metrakit and estoril on my e50. I was running a 66 jet which seemed too rich because I had no low end and when I up jetted to 70 I wouldn't even nudge at full throttle (only a few seconds).
So I went down to the 62 because I don't have a 64 and now it rides like a champ except that I have my idle adjuster all the way in and it dies when I'm sitting.
Is that a sure sign that I'm running too lean? And doesn't 62 seem awful low for a 65cc metrakit, estoril, 12mm bing with a de-restricted airbox setup?
