I recently acquired an old Bayou from a neighbor that I cleaned up a got running, then from nowhere a problem crops up where it refuses to start........ I pull the plug and it has no spark, pulled the plug cap off and laid the bare wire on the exhaust header and still nothing......once in a while though when I push the starter button but as I let off the button it might spark once. Now it did begin sparking normally just once and I plugged everything back in and it ran normally again until I turned the engine off. Next time I tried starting it we were back to no spark or the one spark deal.
I have tested the stator wires at 140 ohm, the pick up at 130 ohm (I can't seem to find a reliable number for these values online), I bought a new ignition coil and ignition switch on chance those may have been the problem but were not, not sure where to look from here......... does the starter relay switch have anything to do with the ignition on these? I know these older Bayou's are magneto type ignitions and do not need battery power to operate but I wonder if there are safety switches involved I may not be aware of. Also, can someone point me to a good wiring schematic for the magneto 220's? Pre 95 I believe.
thanks for any help!
I have a 1998 Big bear 350...the tail pipe/spark arrestor is broke in the exhaust....how can I get it out to replace it? And what's the best way to get the new one in?
Fixing for a friend. Atv was at a different friends house to be fixed and he rebuilt the carb and had it running nice, then it shut off and no more. He replaced the key and the coil.
So he got busy, so I am helping, I checked the wiring from the stator to the cdi, and from the cdi to the coil. All is good. I checked resistance on the pickup coil, good, and on the source coil, open. I buy a new stator (China) and the 4 prong plug only has 3 wires in it while mine has all 4. I checked resistance in the source coil and it's in the 300's. I pulled one of the old pickup wires out of the old stator and wire it in the new one. Still no spark.
Why do the wires differ, I checked the VIN again and it's "J" for the year and I got a 1988 stator. Please help!
So my parents have not let me get my license yet and I need to get around to gets parts and stuff. Answer: Yamaha CW50 scooter. This is a 2-cycle self-mixing scooter that so far, I am really surprised with the power output and speed. It reaches about 45mph since the speedo has been disconnected and has plenty of power for two riders. Its stupid looking, but with some work and a title and plate, it'll take me around town.. My issue is this: No key. I bought it for $150 from a friend and he bought it from someone for $100 who wired in a switch in place of the ignition. That guy got it form his neighbor who's renter left it behind. The scooter will run with this switch on or off (kill switch on handlebar kills engine) To get it tiled and a plate so its road worthy, I need to get the ignition working either by a replacement key or a new ignition. All wires are cut to the ignition and the switch turned on the power to the signal light switch. Also, the 2-cycle oil was leaking out the carb, through the air filter and onto the scooter. also, it runs great, but its making blue smoke with throttle and the muffler is wet with oil.
(I have new signal lights for it btw) So the issues I have with it summed up:
No key (need new ignition) smokes burnt out headlight- can I replace them with LEDs?
