Wheel Rush...The first pick look's like his front fender (Black) with the L-bracket's for the fender mount to his forks (orange) and his brake cable.

That's how I did mine the first time..but they still broke.

Its too bad that there isn't anyone in your area that could help you. Hope you get your engine problems figured out and share them with us.

OK, I know now what I'm looking at !

Did you paint the engine head black ?

Yes, I painted the whole engine black. I used Krylon BBQ paint, and it has worked great.
I am very aware of the whole it will make your motor run hotter - , but the other side of the coin is that black also dissipates heat the fasted.

I had a pic of my plug already downloaded, and when I tried to preview, it stated I was allowed to post only 4 pic's. So, had to make a decision and went w/ the 2 I chose.

I have no idea how unless it was weak at the mounting point. Mine isn't. That's where I have read the weak spot is. It stress cracks at the nut. Maybe there is more than one flaw, but I know there is no way mine is going to break in that location at least. Where did yours snap??

Still . . . Krusin Style,

The weak point is at the bend on the stock brackets, I have broken three in exactly the same place from vibration. I swaped them out for hardware store L brackets and have had no more problems but still check very regularly for cracks...Kelly

Yes....that's usually where they break...I went with bigger L-bracket's and they still broke. I custom made my brackets and so far 5 years, 4,000 miles and they are still holding. But like Kelly say's, I check them often.

My 80cc Mystery solution (I think)

The mystery was caused by many problems, here's a list:
[1] Improperly mounted gaskets (cylinder gasket left gap for air, no gasket on intake)
[2] faulty rear mounting bolt (it sheared right off)
[3] Improper fuel mixture (my bad)
[4] Air leak out of bottom of muffler (the darn thing wasn't sealed)
