|  81 Yamaha Maxim problems help plz....
Hello everyone just joined this site and like the lay out so i thought i would give it a shot.....Well... My problem so far: I bought a 81 yamaha maxim 650 and have been having problems getting it to start. I dont know how long it sat before i got it but i have tested some already problems. 1. compression tested and is good 2. pulled spark plug to test there is no spark 3. gas is getting to cylinders but is not firing can tell because plugs have gas on them. 4. checked wiring replaced all the fuses when i first bought the bike there was a spark but but only the first time i hit the start button every time, then it would crank over and there was nothing after that. I just put a new battery in and now there is no spark! The battery is good and turns it over very well. I have search all over to find info on the web and bought a repair manual but will take a while to get and want to get this fixed. Does anyone know of a good way to troubleshoot this problem? I have read all over that it says to test the coils, rotor and contacts, and other wiring...but it dont tell me how to actually do it? Is there a selonid or fuse that i would be missing for the ignition? Any help would be greatly appreciated! TIA gjewison |
