I'm getting my 17mm PHBG dialed in on my 65 Metrakit. 17 mm custom intake, derestricted Estoril. Its hitting about 45 mph at WOT right now with 16/40 gearing. I went through MarkRyans guide and have it roughly tuned in, slightly rich with a 50 idle and 78 main, W7 needle at richest setting. Again, this is a rough setup and it runs alright but I want to get the most out of this kit and have a solid bike with good take off. And before anyone says "check the spreadsheet", someone obliterated most of the Puch setups and none of the Metrakit setups remain. So what are you guys using?
