Hello to all..my name is Joseph Hodges...my nephew called me 2 days ago to tell me that this 1980 cb750 custom I looked about buying from his friend 2 years ago was back up for sale and the $800 price tag had dropped down to $100....why you might ask..well he let kt just set for the past two years and decited to see if he could still get it to crank up and run..well he put some {way to much} Lucas oil fuel cleaner treatment in the tank and tried to start it..he says it would run and idle out fine but then it started running rough within 5 mins and now he can't get it to idle or run correctly...he also said it needs a new battery and he broke the clutch cable..well I just happen to be 1000 times more mechanically inclined then this guy is..I'm no motorcycle mechanic by any means but I have done my fair share of engine building and auto restoration..I used to build race engines jor Jasper engines in Jasper Indiana and then bolt them to the dyno, breakem in and dyno them out..I feel pretty confident that with the help from the people on this forum.. and my new 1978-1982 honda cb750 manual, and my 7 older brothers and other various friends and family members that we can get this $100 CB750 Custom road worthy in no time...I have not seen the bike n 2 years but its just been sitting in his shed so I kindaknow what to expect when I get up there to pick it up...50 mile drive..I,ll be sure to post up pics as she sits and plenty more as I tear into cleaning it up and fixing it..already planning on going threw the whole eletrical system and rebuilding and syncing the carbs just to get it whipped into somewhat a reliable state..Then I can begin modding thbe looks of the bike..molding it more into what I prefer it looks like..any way that's me and my story..I'll be back with lots of questions that I hope you all can help me with..anyway enough for now..plus I'm about to my destination...later...Joe....ps sorry for my grammar and mis spellings but I'm trying to post this from my Droid while riding shotgun at 65mph in a bouncing truck..lol

Sounds like a R/R (Regulator/Rectifier). Used ones are about $40 on Flea-Bay - or you may find a cheaper deal from some of the chaps here. New ones (after-market) can be had for about $120.

A 750K for $100 sounds like a deal. Use the search function to learn about the issues you'll invariably have in getting this ol' girl back in running condition. A checklist to get your started is in my sig below.

If you can get your hands on a compression tester with a 12mm adapter (for the sparkplug hole), take that with you and give the girl a check. Good compression will make all the difference in how much sweat-equity you gotta put into this bike. Electrical issues and valve adjustments will probably be in order once you get her home.

Good find! Cool

Please read the new member's line in bold green on the home page.

We do not support modifying these bikes by chopping or bobbing if that is in mind for you to do. We do support mild engine performance mods.

There is a lot of helpful information in the link.

Thanks
