A. Okay I used this method when I worked at a lawn mower repair place and we didn't have the right puller to do it right. Loosen up the nut and screw it up to where it's even with the threaded shaft. Figure out a way to put pressure on the magneto itself with levers but be careful you don't break or bend anything else. You just need some continuous pressure upwards. Take a dead blow hammer and stride the bolt head sharply. No deadhead hammer then use a piece of wood against the nut and strike the wood with a regular hammer while keeping pressure on the magneto. when it "pops up" the nut still on the shaft will keep it from dropping off too quickly. It's not the force but the sharp impact with upward pressure on the magneto that… [cont.]

A. magnet and coil A magneto provides pulses of electrical power to the spark plugs in some petrol-powered internal combustion engines where batteries are not available, most commonly those in 2-stroke and 4-stroke engines used in small motorcycles, lawnmowers and chainsaws, as well as in most small aircraft and some racing automobiles, serving a similar function to the coil-type ignition system found in automobiles. In aircraft, typically each cylinder has two spark plugs, each driven from a separate magneto. This arrangement provides redundancy in the event of a failure of one of the magnetos, and two sparks burn more efficiently than one. Magnetos combine the functions of a dynamo, contact breaker points and coil into one unit. The engine… [cont.]

1982 Yamaha xt200j?
Q. My 82 Yamaha xt200j has an electrical system problem that I can't seem to find the answer to. When the left, or right blinker is turned on, the taillight flashes just enough to be noticed. It doesn't cut out, it just dims in sequence with the flashers. I have checked every ground on this motorcycle and every connection appears to match the schematic drawing , and is clean. I need these blinkers to pass NY State inspection ( not sure if it will ). All other problems are now resolved thanks to the help "Yahoo Folks" have given me. Battery is new and is charging with the magneto, switches seem good. This situtation happens with or without the motorcycle running. I doubt this is "Normal" or acceptable with the local authorities. Why does this… [cont.]
