Hey my name is Bleu and I bought a 48cc bicycle motor kit a few months ago. I've been lazy so I only recently started working on it. I ran into a problem where my spark plug doesn't fit my adaptor. I went to Lowe's to try and find one that does and they didn't have one small enough to fit. When I called the place that I had ordered my kit from they told they only had one type of spark plug so they couldn't understand my problem either. I ride my bike to work nearly everyday and this Texas furnace is starting to get to me... Any help and advice would be appreciated thank you!
