Hi!

New member here from Southern California. Let me start by saying thank you in advance for any help and advice offered here. There will be many, many newbie/quite possibly painful beginner questions. Hopefully that's okay, just here to learn as much as possible and work on a cool rebuild project =]

I found this 1976 Honda CB750 on craigslist for $100 and basically said what the hell, I'll give this a try and learn some lessons about mechanical systems the hard way. Definitely willing to put in the time, effort, and money, but clueless as to where to begin.

Some info I got off the bike:
engine: CB750E-2400088
frame: CB750 2048817

I guess my first two questions here are:
1. How to safely secure the bike with a stand so I can start working on it
2. Best way to remove rust or loosen fasteners (the screws and bolts on this thing are extremely rusted over and do not seem to budge)

Plenty of research to do, but any newbie advice is much appreciated. Thanks!

Best thing for securing that bike is a front wheel chock. I have several, my preference is the Condor brand. You can use it on a variety of sized wheels, front or rear tire. Once pushed in, you can even strap the bike to it for added safety.

First order of business is to buy a proper set of JIS screw drivers. ALL the screws on that bike are JIS, not Phillips. That's why several are stripped; some ham-fisted PO used a Phillips. And every nut and fastener is metric, so proper set of metric tools too.

Any steel screw or bolt going into aluminum needs Anti-Sieze applied to prevent corrosion. When you buy your JIS drivers, you also should buy an Impact Driver. That will break loose any screw with little to no damage.

Good luck, have fun, and take your time-

Welcome from Lake Superior,

Is the engine seized?  If not, you don't have to tear apart then engine just because the bike has been sitting for 20 years.  Clean the carbs, check the oil level, check for spark, get a temporary fuel source and borrow a battery.  You may have a runner.

Welcome from Georgia, just want to reiterate the above statements.

100 bux for a 750 is good man...........that's what I got mine for too.
