That's the way the world is going. Who would try and sell a bike with a dead battery. Have these people no fathers to ask. ;D

CB750 / Cb750 Clutch rattle
« on: October 01, 2025, 10:28:42 AM »
Morning. Had a quick site search and didn't come up with an answer. Did anyone ever come up with a truly workable solution to the famous CB750K clutch rattle. Somebody mentioned a Barnett kit, is that a real thing and does it work. Cheers.

Can you still get Avon RoadRiders. They quit making them a while back when Avon deserted the UK.

I should clarify that the one I fitted that failed was a cheap Chinese eBay item not the Silvers unit.

Yes I tried them, it failed in about 5 days. I then fitted a well made unit from Electrex World and it's been right ever since. Cost a lot more obviously, but as they say buy cheap buy twice. I could have sent the failed unit back but couldn't be bothered so I just binned it. Electrex products are UK made and top quality, worth every penny if you don't want to be stranded at the side of the road.

Can weights are just 2 circlips to remove them. Then the Boyer bits fit as the instructions. The hardest part of a Boyer is finding somewhere to fit the control box. Got a Boyer on my 750K5 and it is superb. Bike runs lovely. Bit of a strange procedure to strobe the timing as you have to rev the engine to 5000rpm to set the full advance.

CB750 / Re: Best Electronic Ignition?
« on: July 18, 2025, 09:13:17 AM »
Are you using genuine points or those horrible Diechi things (sorry can't remember the spelling). I fitted a Silvers electronic on my 750F2 about 10 years ago and have never touched it since. It has done a fair number of miles in that time as well.

Julie is right though, probably best to find the condenser issue first.

The sleeves were made out of stock mild steel tube the right internal diameter to slide over the painted frame tubes.

The bolts were drilled through for slight clearance on the front, but drilled and tapped in the back. The bolts were then screwed into the tubes and just gently nipped. Then a nylock nut was tightened onto the back of the bolt to secure it. That way there was no need for sleeves as there's no crushing force, plus the threaded part located the tubes perfectly.

It was done about 12 year's ago and not the slightest problem with it, and the bike has been used quite a lot. I took it apart about 5 years ago to fix a leaking rocker box gasket and it came apart okay. I did coat the insides of the sleeves with copperslip when I originally built it and that helped. Would have been an engine out job without the modification.

You are looking for a rare part if my search is anything to go by, even complete bike are scarce now and over £1000 on fleabay.

That's not the problem Bryan. It started with a base gasket oil leak at the front. Bodgers fix was to fill the area with plumbers silicone. On stripping, the barrels have been welded at some point and the they have distorted with the heat. The gasket face is not flat. Also has an incredible bodge to the front lower made up of wire wool mixed with JB Weld to block something up. Cant see what it is as I cant get it out. Thought I had seen most bodges but that one is new on me. Easier to just find another decent set of barrels and swap my good liners into that.

I have a friend who just dropped off a 1980 CB250N that needs repairs. Just wondering if any of you wonderful people have any stashes of parts available for that model. Am firstly looking for a good set of barrels and a left hand exhaust header pipe. It's allowed as its an SOHC Honda. Cheers.
