Re: Still getting really bad gas mileage.
So see what you think of this, i just removed my spark plug, which is the stock kit one that i have been using the whole time that i have had the bike. The porcelain insulator in the middle is very gray colored, which i would think indicates very lean running, but it 4 strokes at wot. Now this wasn't a proper plug chop, this was just after riding for a while, with plenty of idling and stops, and also quite a lot of WOT. What does this mean? Should i adjust the carb clip down a notch?
My motorized bicycle is cooler than your Vespa, even though you can go faster.
