My starting point would be the black earth cables on the mounting bracket. The one in the video has little chance of earthing as the frames paint is still on. Make up another wire from the same bolt and take it to the earth either on the loom or a good reliable earth on the frame somewhere. Suspect those dodgy red cable connectors as well.

Did you hear anything back from common motors? I think you need to chase down the no spark situation before anything else. If you can get it to run you can ignore the coloured timing lights and strobe it.

Yes that was my problem on the Bomber. Unfortunately I ran out of adjustment. I considered filing the sides of the sensor plates to get them closer together but it would have made little to no difference as it was so close anyway. Bit of a design and manufacturing problem I think.

Yes I noticed that. I think it's just a different decision on how to best fit everything. Sensor position doesn't matter as long as the rotor is keyed correctly to accommodate that position. My biggest problem was getting both cylinders timed, as you can see the sensors are actually touching and there was no movement left. I had to half the difference and this left it very slightly out but it still runs well.

Now your asking a big question. From memory (it is quite a few years ago now) the K5 rotor and sprag clutch fits and the timing marks should be the same. That said, there are a few engines out there with a different crank configuration that were used mainly on the police specials. They are that rare I doubt you would have one of those. So if the rotor is correct but still doesn't line up correctly something else is amiss. You didn't say what work has been carried out on the engine? Is it possible that the cam chain is maybe a tooth or two out that would put the cam out of sync with the crank. There are timing marks on the camshaft that need to line up, I would check that first. Also check that when the TDC mark on the rotor is set that the piston is actually at TDC.

I used a "Charlies Place" electronic ignition, and to get the timing correct it was right at the end of it's adjustment. I never did get to the bottom of why that was as it ran well in that position. But there really was no adjustment left. Just a thought, is it possible to get back to the points setup and see if all is okay, or was it already running on points before you decided to fit the electronic. As I said, you didn't mention the bikes history before you attempted to fi the new unit.

I didn't back them off, didn't want to risk it. Some were nearly loose anyway. Appears to have taken a retorque okay though.

Really sorry to hear that news Phil. I have a good friend struggling with cancer at the moment. Sounds like the brain guy is on top of the situation so best of luck mate.

Sorry it's taken a while to update, I have a friend who has terminal cancer so I have been busy reassembling his Kawasaki ZXR750 so he can sell it.
Finally got round to the 350F last weekend and got the cam box off and down to the head bolts. On original assembly, the head bolts were tightened to 22.5NM in the correct sequence, going through 3 stages then left 24 hours and torqued again.
On checking them now, some are barely past finger tight and non were still at torque. So again I have torqued them down in stages this time to 24NM. They were loose, really loose. Following reassembly the bike started first time (that had become rare) and no obvious oil weep, it also ran really well. When I looked closely at the gasket it had mushroomed out of the joint slightly which is unusual. I think it was an Athena head gasket that I have since read bad reports about. It does look to be a good bit thicker that a standard Honda item. Anyway, it's good now just hoping it stays that way.

Scratch that about the extra thick O-rings. Done that many jobs in the past few years my old brain is a jumble. Looking back at old posts shows that the thicker O-rings are for the 750. Dementia strikes again.
A re-torque would be nice as it's quick and easy. No need for taking off air box and carbs or the exhausts, plus it doesn't cost anything.

Cheers Ken. If I remember correctly the head gasket is Athena/NE, but it's so long ago I cant remember if the o-rings were standard or thicker. The oil jets are no problem as there's good flow to the head. I may as well re-torque the head before I take it off. If it takes a re-torque to 21.6NM because they have come loose or the gasket has compressed I will give it another go. If it wont torque up anymore I will take the head off and have a look.

Hi. My CB350F (the one in the Avatar picture) has started a slight oil weep from the right hand side front of the cylinder head. Leaking between head and barrels. I know Trigger recommends an o-ring thicker than standard at that point which I can't fully remember if I did (done a lot since then). Is it possible that the head just requires re-torquing down, and if so, is it safe to slightly over torque like recommended for the 750. Or should I just take the head off again and fit another new gasket and o-rings. The bike has only done 400 miles since its rebuild years ago. Cheers.

Have you got a photo of the electrics behind the side panel.

Is it a USA spec bike with the safety unit.

Did not know that Julie but not surprised, do we know where they went?
Yes, I do as I was discussing it with someone a few weeks ago but for the life of me I can't remember who bought everything. I know it wasn't P&K though.
Edit..... I remembered 😊😊😊😊
