Thanks for the words of encouragement guys, it's appreciated. Bryan, on the twisting method, do you do that with the bolts slackened, then tighten after getting alignment, or is it done after initial tightening. We used a similar method back in the day after one of our many minor tumbles, but I don't recall if we slackened off the pinch bolts first, in fact there are a lot of things I don't remember.

First ride out today having had the engine running last week. Took some pics and included an original from when I first got the bike to show the difference. Engine ran well, smooth pick up and stable tickover. First fill up, then first problem, bike started to stutter about a mile from the garage, erm, fuel tap off! Realised this and turned on and all well again. Amazing how we get used to our modern bikes and never having to think about these things, I had turned it off at the garage. Gear change too high needs adjusting. Some clutch slip but this improved during the short ride so need to monitor. However, one bigger issue, immediately apparent that handlebars were not square in order to achieve a straight line, they are slightly to the right. Balls.

When I rode the bike before the restore this was not the case. I have had the stanchions refurbed at Philpotts so they are now straight, there was a slight bend in them that was visible when removed. So I guess this means one or both of the yokes are bent OR I didn't put it together correctly. As I am not really happy about the balls, and I nicked the lower yoke with the dremel to remove the lower ball cup, I was thinking of putting in a replacement yoke with taper bearings in any case.

Anyhow not too bad for starters and, still no oil leaks!

Getting there Ted. The weather has been great for motivation recently, let's hope it's better than the forecast over the next few days, 8 degrees is going to feel bloody cold. As a matter of interest, where did you get the idea for putting silcone sealant in the exhaust joint? I have re-used the old gasket as it was in good nick but haven't checked yet to see if it has made a full seal.

Looks very neat Ted. I'll bet lots of 400's have the loom under the coils. Mine was. However I have routed as per the diagram above them, let's see how it goes.

Video is a bit blurry but you get the full glory if you download it. Something to do with HEVC video on iphone not compatible with blah blah blah. Something for me to work on.

Welcome Rob, can definitely recommend parakeet yellow especially as it's one you haven't had before!

Sorry for the pre amble but a significant day in the rebuild. Dithered about starting the bike for the first time today as it started off badly, touchy negotiations with neighbour over a back fence dispute, puncture on dog walk, crap customer service by National tyres in Corby, 1/2 hour wait followed by we can't fix that, £195 quote for a tyre they can fit tomorrow, well I don't live that near to Corby it was the nearest place to the dog walk. Tiptoed back home and organised same tyre tomorrow for £120 by my trusty tyre fitter. Anyways sod it I got things ready for a start up, including tipping the bike from side to side and moving the overflow tubes into a viewable position as the carbs leaked again, and much to my amazement ..... it started. Lots of tinkering left to do! No oil leak from the area of the crank case I was worried about as discussed in my earlier posts. Touch wood! Sounds absolutely great!! Occasional reluctance for revs to fall back but did start to improve after a little bit of running, hopefully this will settle down. Enlisted wife to video the event, hopefully link works. Start was from stone cold, genuine first attempt, no cheating!

Misc / Open / Re: LED H4 replacement bulbs experiences anyone.
« on: March 16, 2022, 04:36:20 PM »
I can recommend the one below. Fantastic and the same beam pattern as a standard H4. Pricey at £33.00 but passed an MOT with it fitted and transformed the headlight on my CX500.

Link takes you to a bulb that is £65, that's inflation for you.

Carbs finally leak free having fitted 4 new float valves, leak free for now for now anyway. Tried the starter motor, nothing doing. Checked continuity to starter button and found it to be intermittent, took it apart and cleaned it out, too liberal with the dielectric grease when I worked on it about a year ago I think. Continuity sorted, still a no go. Tried the spanner over the solenoid contacts and the starter turned fine. Traced the actual fault to an oxidised female connector to the neutral light on the solenoid so put on a new connector which sorted it. Didn't take many turns of the engine for the oil pressure light to go out so that was a relief, I had kicked it over quite a few times previously. Not many jobs left before an attempt at starting!

CB350/400 / Re: WoW - Chroming is how much for the front mudguard????
« on: March 12, 2022, 09:49:15 PM »
Slacken off the top screws, the 2 pairs on the outside of the guard, you should then find it goes on OK.

« on: February 28, 2022, 10:19:43 AM »
I think it possibly comes down to what tools you have available, everybody has a hacksaw but I'm guessing Ash you used a pillar drill? If I had six to get out I'd buy a pillar drill! Just one then get yourself a good hacksaw blade, I used a Bahco and had to grind away a millimetre all along the top of the blade before I could fit it through the tube. If you used an ordinary hand held drill then fair play to you Ash.
