That's pretty cool. I do wonder though what the crash protection would be like as not much distance between the driver and the front of the car.
Very good idea though and this is what I think EV's are best suited to, urban short runs and considering these are the types of journeys most people do they would be ideal especially on London and other cities.
The price though, that's the killer.

I would guess that sounds right Ash. I know he buys his stock from all over the world; it must be pretty interesting as I would guess it would be between him and CMSNL as to who can get to the spares stash first and claim it!
Got to hand it to DSS though, without him how many of us would be in a position to have restored one of our old bikes back in the 90's. Just wish he would give a deal to the VJMC and SOHC Forum members though and he would probably benefit from it in the long run as more people would restore more bikes and thus order more parts from him.

Welcome to the forum Phil.
The CB650Z was a nice bike back in the day and was probably the ultimate development of the CB550 engine. They were overshadowed at launch by the then new CB750/900 DOHC models that obviously took all the glory. I know very little about these engines other than the primary chain wear was not the issue on these engines as it was on the 500/550's before it. Good luck with the carbs, I think these used the PD type and known for issues.
Lots of advice on here and you'll never be stuck with a problem.

I know DSS buys most of his stock from dealers getting rid of their old or slow moving stock (or he used to, I guess the retro market has picked up a lot since the 80's & 90's and the stock is now in demand by people like us). Where did DSS buy his initial stock from to get started, was it Honda UK although Nigel's post would make that seem impossible if Honda themselves sent it to landfill?

There is a wire circlip you need to winkle out with a fine pick.
Wow, I didn't know that Ash  . Well done. Is the bit that suffers the wear the ball or the socket (sounds like a hip joint!)?

I have tried a couple of times in the past to get the joint apart but failed! In the end I took the complete gear lever for chroming but as I knew the plater I asked him to do his best to avoid damaging the joint and to his credit it came back all ok. I don’t know anyone who has managed to separate the joint to reassemble it.
The actual joint is a weak spot on the 400/4 suffering with high wear and becoming sloppy.
I think Ken (Oddjob) on here did try to make a conversion using a rose joint arrangement, I don't know if he completed it. You may find something relating to it if you try a search on the 400 and 500 pages although when he left Ken deleted a lot of his posts unfortunately.

I think you are right Matt. I went onto the GSPC website and typed in my NGK plug code and that was the answer I got for the ND plugs I need. I have just gone onto the Spark Plug Ltd site and it is showing the same plug as you state, something strange going on!
I have now placed the order with the Spark Plug Ltd and given up with the Green Spark Plug Company after waiting nearly FIVE weeks for my order. I have contacted them twice to chase up the order and didn't even receive a response the second time. Terrible customer service so have asked for my money back and left them an appropriate review to reflect my frustration in dealing with them. How can a company show items as being in stock with a two day delivery at the point of order when clearly they don't have stock and are waiting on a delivery from the manufacturer! If they didn't have the stock they should have offered an alternative plug from another manufacturer instead of the radio silence!

According to the Denso site the plugs you need are Denso-X22ES-U 4. I ordered a set from the Green Spark Plug Company on 24th April and I'm still waiting for them! I have chased them up twice now, the first time the response was they are waiting for Denso to send one plug to complete the order and second time I received no reply at all. Pretty shoddy service really and I wouldn't recommend them.

Is that instant gasket on the rocker cover? There appears to be a lot of gasket debris on the edges of the mating surfaces and into the threads. You didn't use liquid gasket on the crankcase to barrel joints did you because that can be squeezed into the oilways and block them and that could well be your problem. Likewise if loose instant gasket debris floats around in the sump it can be picked up by the oil pump and sent up the oilways and create a blockage at the restrictor jets.

A stupid question but is the roller bearing damaged and worn? The gearbox on Ratty had over 45k on it (probably over 50k as the PO had fitted a mini Speedo on the bike at some point). When I checked the roller bearings they were fine, no play, no nasty rumbling and no tight spots. The rest of the engine was in a terrible condition as a result of the PO blasting it with a sand gun. The roller bearing was good to go again but unfortunately the shaft was worn beyond repair and I purchased the two gear shafts from Ted. I have no idea how many miles were on that gearbox but again the roller bearings were absolutely fine.

I would be tempted to get some local heat onto the spacer (not the shaft itself) followed by some gentle taps with a suitable thin and flat wooden wedge GENTLY inserted between the spacer and the bearing going slowly all the way round, these things usually let go with heat and gentle persuasion. If the wooden wedge doesn’t work get that old flat blade screwdriver out that you use to stir paint with! Good Luck.

I've just noticed the oil seal is not on the end of the camshaft, did it fall off when you took the rocker cover off?

I would expect to see a bit more oil in the oil bath below the cams if the engine has been running for 3-4 minutes. Did the top end sound rattly when first started and did it quieten down after the oil began to circulate or did it sound the same? I am not really experienced with these engines but if one side of the head has more oil than the other I would be concerned the oil jet on one side is restricted and not delivering the correct amount of oil to that side.
The cam chain is picking up oil from the bottom of the engine as it goes around the crankshaft sprocket and it could be splashing oil at the top end as it comes back up to the camshaft. The oil filter is also in the bottom end where oil pressure is likely to be unrestricted.
It will be very messy but I’d be tempted to run the engine on the starter motor in short bursts with the rocker cover (and fuel tank) taken off and see if the oil is reaching the top end.
