I got around to pulling out my starter solenoid assembly on a bike I've started working on to do the necessary solenoid clean/tune up, and low and behold there was/is no pinion spring or thrust washer in there! This bike had been rebuilt and bored over for/by the previous owner, so no doubt the engine has "been into".....just not all the parts put back in........I assume basically the starter/pinion/solenoid can operate without them, but of course they are there for a reason!
Nothing like left over parts on the work bench after a "professional" rebuild huh. There are other ways to shed weight and simplify that bike. I'm paranoid at what other vital organs may be missing now.
Anyway, I've yet to look, but what are my odds those parts are still available new? I may have a spare spring laying around, and can probably produce a thrust washer, but my first thought is to just find a honda part for each maybe....Those expectations may be unrealistic, but I'm not going the $30 route on ebay for a spring either. Time to search the parts bin and compatible substitutes.
