Motorcycle Repair: Tearing up solenoids, starter solenoid, compression stroke

Question
Hi, I am also from Ohio, Cleveland area. Own a late 1984  fxr evo. I too have a problem with the starter solenoid sticking. The bike is pushing 170+ psi in each cylinder and is tearing up solenoids every 2000 to 3000 miles. I have installed a 1.4kw starter, replaced the breakers and starter relays, installed the shortest 4 gauge cables I could find and made sure that the starter was grounded properly at the housing. I also have replaced the battery with a big boar 350cca battery. I also have tried to start the bike with the start switch in the off position until it starts to crank, this only delays the inevitable. I have taken the last 2 solenoids apart and found that the copper washer looks as if I have been arc welding with it, pits are so deep I cant get them out without destroying it. After replacing the solenoid with a new one all is o.k. for a while. Although a noticable delay is present right after pushing the crank button, the bike will turn over but it takes a second or two before it cranks. I can hear the starter engage but it takes extreme effort to turn past the compression stroke. After 1500 mile or so the solenoid starts to click real bad until I get the motor off of its compression stroke. Which is not fun to do. Putting it into 3rd or 4th gear and trying to roll the bike forward or backwards. Are there any high current solenoids? I have used $39.00 accells and $100.00 harley replacements and all is the same. 2000 to 3000 miles and a new one has to be put on. I have also checked to make sure that the starter jack and shaft aren't binding. All looks o.k. to me. Bushings o.k. not alot of slop. Please help as the bike is getting to be undependable.

Answer
Here is somthing that seems to work. remov ethe solenoid and spring. Install a spacer inside where the spring goes. One that is the same size as the hole and .1 thick. .1 is slightly over 3/32. I would also install a new spring. Put the spring back in and install the solenoid. I would put a new washer in the solenoid. What this will do is push the washer tighter to the wires and make better contact
Good luck and happy riding
