So I’m running a 70cc kit on a puch maxi. With a techno circuit pipe and a high flow air filter! There’s a 14 bing that looks like they dremeled the part where the filter goes to try and make it a 15?! I got it with a 60 jet in it. So I decided to Upjet to a 74,70, 64 and it ran really weird with those sizes. It would bog at high speed!
This is what my spark plug looks like!
