Question about spark plug heat range

DanielMaia · Jan 17, 2011

Hi there,

My 60cc motor revs good, but it gets really really hot! Im using right now a B6HS. Should i use a higher heat range? Like B9HS?

9 is probably too cold for these bikes. i run a 7 in southern california, year round.

how does your plug look? these engines run pretty hot anyway, but if your plug looks nice and cocoa coloured, it's probably fine for it.

But first make sure the carb float shuts off the gas inlet valve at 21mm. If its set for more than that then it will automatically be too lean.

Ya got pictures of that?

After 400km, it runs better and colder
