When we first started chatting about idling issues and intake/head leaks, I did find a leak in my head gasket. The nuts were a little loose.
While putting the wrench to it, I pulled the head off and applied a 1-2mm thick bead of silicone to the body and let it tack before reinstalling the gasket and head.
Object was/is to seal the head without sanding. If it was leaking due to an imperfection, it isn't any more ;-)
On a slightly different topic: my fork broke last week. The profile pic I have is no longer my motorized bike :-(
I now have a 700c road bike instead of the 26" cruiser.
Still using the same handle bar, stem and motor. Only thing I truly miss is my wide spring loaded seat.
A great ride even though the tires are half as wide.
Its a flip flop fixie. I've lost my hill climb ability (with out my 7 speed hub) and some off the top end. Thankfully its mostly flat for my commute to work. Just have to leave a little earlier and pay attention not to beat the motor too hard. I did just get it running right after all...
Next is a 3 speed cassette to replace the single cog freewheel and a larger chainring on the front freewheel/pedal crank. I'll have my hill climb ability and top end back...
