Project bike: dive in or jump off?
« on: July 30, 2016, 12:06:21 AM »
Hi guys\gals,

I have an '82 cb750 sc project bike I need to get running or sell. I'm hoping to get some feedback on the practicality of starting this project. The story I was told is the previous owner was knocked off the bike on the highway when his riding buddy was sideswiped and washed out in front of him. Ouch! The bike flipped and needless to say it was totalled.

The fenders, tank, bars, controls, pegs, seat, lights, side covers, muffler, engine side covers are all wasted. Luckily the fork and frame seem to be straight. I replaced the bars, engine covers, master cylinder, throttle, battery, oil and clutch lever about five years ago and it started up and ran but lost power when trying to ride around the block. I was ready to cafe it at the time, but moved to the city and had no place to work on it.

Now I have a driveway to work on it and access to a blast booth, paint booth and large powder coat oven. I'm not afriad of taking apart the carbs, fork or other parts of the bike (thanks to a little aptitude and lots of awesome people on the internet sharing their knowledge). However, I don't have a ton of free time to be wrenching and don't have another bike. My main goal is to get a fun, affordable bike to cruise around on and occasionally commute with. I love the style of these bikes, I'd prefer to own an original, but building a simplified (brat, cafe, naked) bike with what I got seems edifying to the soul.

Given a bike in this condition, on the low end of cb750 year\model spectrum and a real desire to ride without spending a ton of money\time to be able to ride safely; should I dive in or sell the project and get something ready to roll?

Thanks for your opinions!

Hello, and welcome. With you wanting to get riding quickly and safely, and with as much of the bike you say is "wasted," I say find another bike in good mechanical condition. This forum is dedicated to the SOHC bikes (for 750, that would run through '78) So you might not get all the answers you're looking for here. Also the post 78 cb750 sell for considerably less than the earlier ones, so I think you would be putting way too much money and effort into getting it running safely when a nicer starting point could be had for cheap. Just my thoughts. Good luck.

It takes always much longer to finish a build, I would say find a running bike.

Find a running bike, keep this project, and work on it as time and money allow. Checks both boxes on your list  ;) The project bike doesn't cost you anything to keep, and won't yield any return when you sell it.

Not worth the time/money going by your description of being totally wasted.  Buy another and enjoy riding.  On the positive side the 750 SC was one fun bike to ride-smooth, somewhat powerful and lightweight.  Welcome...Larry

Thanks for your input and directing me to the DOHC site. I hope to get a early model 750 one day... Until then happy riding!
