My Grubee Super Rat 66cc just arrived and I have been looking it over. Compared to the engine that I bought from Spooky Tooth a couple years ago there are a lot of noticeable improvements. The whole thing just looks beefier. The internal magneto/CDI is clearly better designed and built.
Has anyone removed and successfully replaced the skinny plug wire with an 8mm wire? I called Robert at Piston bikes and wasn’t sure because he hadn’t taken apart a Super Rat. We both think it’ll be a simple twist off and twist in…but I would prefer not to be the guinea pig on this one.
Anyone with a Super Rat made or attempt this mod?
