squeaky noise in left turns..

Front wheel bearings/axle? Might the tire be rubbing on the fender with those side loads?

Thanks for the reply.

I put brand new wheel bearings and steering head bearings when I rebuilt it several months ago.

I checked the front end yesterday and one of the bolts attaching the fender to the fork legs wasn't tight. I haven't driven the rig yet but hopefully that is the cause..

I should really look for a fork brace..

I broke the factory aluminum fork brace on my Honda. I replaced it with a steel one. Lots of side load on the system.

Do you know where I can get one?
I looked at SOHC4 forum but they seem to have difficulty finding the supply..

Google Superbrace, they still have them for the old Wings.

They don't seem to have one for CB750..
Oh well.

You might try asking that question at the AHRMA site. I don't know if anyone races those big things, but if so, someone might know of a source. Alternatively, someone associated with the group might make you one.
Last thought would be- is there a front end with bigger (stouter) forks you could swap?

Shigeo,
Didn't you swap lower legs for a pair that had the axle located in front of the center point for a trail reduction?
If so, many of the earlier Honda's with the anti dive feature have a factory installed tweak bar that might be incorporated into your front forks. If there is a bike salvage company near you, you might check for a front end with the same size lower legs that are the same distance apart as your current ones. That model with fork brace would fit your setup.

Here are 3 examples: '80 CB1000, '82 CB650 and '84 CB650.

I see some people use Gold Wing front end..
But if I go that route, I would like to use leading axle fork legs..

I haven't.
'79~ CB750C has different brake caliper design and Comster wheels.
I want to keep '75 CB750K's spoke wheel, that means I have to do something
for caliper mounting.

Mine does the same thing. I noticed that I needed to retighten the axle and also adjust the caliper spring loaded admustment screw. I was able to get rid of at least 90% of the squeak.

I had found after replacing front tire that my speedo drive was not snug, it could rotate some so I loosed the axle caps and snuged things up, redid the caliper adjustment and now it's ok. Might try that first.

BTW I have a 78 750k with V562.

Thanks.

I will try it.

I didn't have time to test-drive the rig this weekend.
Plus the weather was lousy..

When I hear a squeak or a clunk from low up front, the first thing I check is the lower front sidecar mount. They will often make a noise in a turn if they are loose or starting to break.

Yes, it could be almost anything, but in my experience, it is worth checking the mounts over very carefully...

Many times these mount type noises can even be heard or detected by just pushing the rig around in left and maybe right circles. Sometimes they may be an issue and sometime maybe not really.
Vernon referred to 'clunks' as wel as 'squeaks'. To me a clunk indicates a problem for sure as someting is just not right. As squeak although it shoudl not be there may or may not indicate a real issue. I have traced squeaks to play in lower mount heim ends. Is this acceptable? Not really but it is also not an extremely huge issue in most cases. I do not as a rule use heim ends personally for various reasons but they are in vogue as lower sidecar mounts right now.
Sometimes a passeneger who is willing to lean and ear to various places on the rig while underway is a great tool in detecting strange noises. Be carful out there as we don't want to hear of any accidents related to the passenger falling off or sticking a finger in the spokes or anything.
Some of you have probably met Ron 'air sidecar' Smith at the RON DEE VOOs ...Ron is my number one sound detection guy. I won't go into detail here but he has taken a lot of wild rides on empty sidecar frames while lending an ear here or there to check out suspecoious noises. More nerve than me that's for sure...lol.
