Topic: New project in San Diego

[Edgar]

Hi guys. Just bought a 1977 750k a few weeks ago. Previous owner says it runs but needs carbs rebuilt. We shall see. This is my first big build, I used to have a Suzuki savage 650 a few years back, and I currently have a little Honda ruckus that I wrench on now and then. That said, I'm a very novice "mechanic" so my goal is to get this bike running and then I have a mechanic that's going to go in and check the engine, sync the carbs, and handle any other complex problems.

Sooo, I have the bike, and the carb is in a box. Could you guys please help me out on what I need to buy please. I'm going to order the carb rebuild kits (with jets) and then what else do I need to put it back onto the engine? I don't have the airbox so I think I might as well go ahead and order the cone filters, living in San Diego what Jets would you guys recommend for cone filters and the stock exhaust? Thanks a ton to anyone who actually read all this and is willing to help! It's a bit overwhelming as my previous bike was running and wasn't a project like this

Here's what I have








Thanks!

Consider getting an airbox, it makes setting the carburetors so much easier.  Not just setting, starting and running and unlike pods it will not mess with the engine when you are stuck riding in the rain.

You can ask here in classifieds or check ebay.

And welcome, bike looks decent

Also rebuild kits, there are people who buy original Honda - still available at some Honda dealers -  pricy  but correct. I had good luck with aftermarket carb kits, your call

And you probably don't want to swap the jets or needles. Best to stick with stock Kiehin brand. They seldom wear out, so you can reuse them.

All the "screws" on the bike are JIS, not Phillips. So buy a proper set of JIS screwdrivers or bits, and you won't have any issues removing them. Look in the Parts for Sale section and member RRTools sells a very nice 8-piece set. Lastly, Mark Parris' book is a must have for rebuilding a 750. (Also in the PfS section).

Welcome to the obsession!  I'm in Oceanside and am getting pretty close to completing my CB550 project.  Let me know if you need any help!

He most likely has some for sale, and he is a great guy to deal with.

That Bobco, he's a member here.  That thing is rough, but cheap!  It will clean up but you would prolly need new rubbers...

I would defiantly stick with the stock air box. Those are always the best bet to get your bike running at top performance and without a headache. Truly stick with the stock air box if at all possible. As for the carb cleaning, I’m sure there is a great detailed description of what process to go through when disassembling/ assembling and what passages need the most attention. New O-ring are always a good option depending on the age of the carbs since the last rebuild. Do not try and remove rusted screws with Philips screw drivers. In a pinch I use a pair of vice grips to get old seized screws off without stripping. Then replace with Allen heads. If the carbs need a complete disassemble and cleaning you will need to submerge in pine sol 50% water 50 % over night, but I’m sure that is detailed in this forum. Ask for a good link about carb cleaning from one of the forum mediators. Good luck and be safe!

Yeah I've decided to go stock airbox. I've been watching the hack a week videos and in his latest he discusses why he's going stock, and it makes sense. I've been so busy and haven't been able to sit down and order parts yet. This weekend I'll probably sit down with the back and order all the carb/airbox stuff I need.

Umm, what battery are you guys using? Anyone using the maintenance free ones?

I am using a BikeMaster TruGel MG12A-4A1 Battery in my 1977 CB550F

So I'm still in search of a decent airbox, I messaged the meme we here who someone recommended and he doesn't have the one I need right now.

So, do other model airboxes fit? Mine is a 1977 750k, but there is one currently on eBay for a 77 750f, direct fit?

Also, when I was watching hack a week, he got the rubber boots done by a guy named ichiban moto, does he do custom work or sell parts? I looked him up but the only thing that comes up is YouTube videos.
