Hi there, I’ve recently installed a Naraku 70 cc kit on my super 8. Running a 86 jet with stock airbox which I took the snorkel out and a Leo Vince sito pipe. Starts up pretty much first kick and idles up nicely. Acceleration greatly improved, I’ve only gotten up to 40 mph briefly as I’m trying to break it in properly. However, twice it just died on me whilst riding, I’d roll off onto a pavement and start it again and it’d run like everything was normal. Wondering if anyone has any experience with BBK on these bikes and could give me an insight of what the issue might be.
Thanks

You are soft seizing (overheating). Pressue test your cylinder first. If it holds 6 lbs for a half hour you are good to go. If it doesn't hold pressure, reassemble with hondabond. Next step, get a temperature gauge. I am using a $25 one from amazon which works well. Tune the carb (jet size, needle clip position) by temperature. Tune the variator (rollers/sliders) using the tachometer. Keep the engine under 350 degrees, the lower the better.
