I'm looking into aqua basting or vapor blasting or whatever you want to call it but I cannot find anyone in the US that I can send my parts out to. Any recommendations?

Tnank you

Bike is a 1970 Harley Davidson dirt bike. If I am correct I can just wire a toggle switch in-between the magneto and the ignition coil to kill it? I'm trying to make a very stripped down fail-proof trail bike, no lost keys, bulky lights, horn...

Cool thanks. I just didn't want that extra wire coming out of my motor and not being hooked up to anything else. So If I wire both coils together and then connect to ignition coil will it provide a more powerful spark?

If my magneto has an ignition coil and a lighting coil and I am choosing to wire the bike without any electrical system is it a problem to remove the lighting coil from the magneto if I am not using it? Would it throw the balance of the flywheel off?

I saw that but I just cant justify putting a $100+ piston into a old beater trail bike. I found these.. http://www.ebay.com/itm/1980-1981-1982-1983-Kawasaki-KE125-OEM-Piston-std-size-56mm-13001-1124-/130700674265?pt=Motorcycles_Parts_Accessories&hash=item1e6e5e04d9&vxp=mtr...

Took apart my 1970 Aermacchi Harley 125cc engine and the piston is shot. I did some research and found the standard piston size is 56mm and apparently the stroke is 50mm. It is next to impossible to find a NOS piston for this engine but there are many 56mm 2 stroke pistons on ebay, most do not...

FOUND THE PROBLEM. Quick inspection revealed nothing, then I took the head and jug off, piston is cracked around the rings, missing a ring, missing gaskets.. Someone took it apart and slapped it back together just to sell. Thanks for the help.

On my other bike someone used a jumper cable on the rectifier to bypass the battery

Yes, although none of these bikes ever have the battery. Bike came with headlight, taillight, a couple other misc. bulbs, horn, ignition switch, rectifier

Yes the plug only sparks when is grounded to the head

It could be that I am not testing this motor right. I have both magneto wires directly connected to the ignition coil, no kill switch. Is this correct or am I just stupid? I bypassed all wiring.

Not quite in the city, but this looks pretty good http://chicago.craigslist.org/nwc/mcy/4343739825.html

Gaskets all seem to be in check. I rebuilt the carbs and all looks good. points were just cleaned and adjusted to .016 gap. The spark from the plug seems to be OK but I don't know. Looks to be a little weak but I am relatively new to this so I don't know what a "hot" spark looks like. The piston...

Its premix. The cylinder and piston look great. Engine does not have reed valves, its a pretty simple motor.
