[QUOTE="1984RM250, post: 692529, member: 46347"] I know I posted a message a while ago but I am still stumped. Right now there is no voltage coming out of the CDI box... I bought it with a hole burnt in the top of the piston which i figured was due to the 210 main jet instead of the 270 stock one. After I got a new piston I installed the 270 main, but the bike ran like crap and had absoltely no mid or top end power. I tried many different sized jets without success. My brother suggested that I check the stator and flywheel and clean them and mess around with timing. Finally after many trials, i found out that the stator had to be adjusted all the way advanced for it to run right. This seemed a little funny to me but i just rode it anyways. Every once in a while the bike would just shut down, especially when I was riding while it was wet. When I pulled the flywheel cover off, everything inside was wet. There was a small piece of the cover broken off and that was letting water in. I took the stator off and cleaned it and the flywheel off. That worked good, but each time it got wet inside, the bike seemed to run worse and worse. There are exposed wires on the coils that were soldered there. I'm wondering if the coils could have gone bad. One coil is producing about 30 volts AC and the other is producing about 3 volts AC. This seems too low to me. Another thing that bothers me is that the CDI box is not the right one. I saw a box for an 84 250 on ebay and it looked like it was black plastic. This one is metal and has the numbers CU1169 32900-41321. I was told this is not the right box. Should this matter? Would the wrong box make it a need to advance the timing all the way? I dont have my owners manual so I dont know what voltage and resistance my system should have for testing stuff like this. Any help would be greatly appreciated. Thanks, Shawn [/QUOTE]
