Looking for a local sparky to help me with an old 6 volt Honda C50 step through which has no spark.
I’ve replaced everything electrical on it points, condenser, coil HT lead cap and plug and cannot get a spark. Other than checking continuity that’s as far as my troubleshooting skills go, so really need help from anyone that can come and have a look at it. It was running briefly about a year ago but since then It will not spark. Any help will be gratefully received with all the tea and biscuits you can handle.

Hi all, is there a technique or tip to refitting the air plenum between the carbs and air filter box?
I’ve been struggling to get the 2 sides fitted, if I do the carbs first I can’t get the plenum to fit over the oval duct at the air filter and vice versa. I’ve tried gently warming it up to make it a bit more pliable but that hasn’t helped.
My big mitts probably don’t help but I feel like I’m missing something simple. Thanks Alan.

Thanks Julie I’ll set the floats up using your guide. I’m not sure I follow Bryan’s guide for setting the slides will need to have another read on that. If I’m understanding it correctly after undoing the tick over screw you set the lowest slide with the drill bit shank as a feeler gauge, do you adjust that slide with the slide adjuster then set the idle screw to that position? Then adjust the rest to match. The way I read it you set the slide height with the idle screw and then adjusted the rest with the slide adjusters. Probably my bad. Thanks again.

I’ve recently overhauled my 77 400/4 carbs with a kit from the USA, from 4into1.com had the kit for many years but never fitted it. Now that I’ve done it the float height is concerning me slightly, the bottom of the floats do not sit parallel to the face of the float bowls but neither did the originals before I took them apart. When I measure from the face of the bowl to the lowest point of the float it measures 21mm which is what I understand it should be, but at the high end of the float it measures 23/24mm. Should the float be a constant 21mm straight across or does this sound right?
Also any tips on setting them up statically before refitting them.
Thanks in advance.

If you haven’t used one before I’d temper your expectations on the results of using your ultrasonic cleaner. I’ve had mixed results with mine, what I’ve found is very heavily contaminated parts don’t clean up that well and I’d clean as much off by hand before you put anything into the cleaner. I’ve used the carb cleaner in mine and I’d say it was ok, again things don’t come out gleaming looking brand new but they do serve a purpose. Something I’ve tried which has given good results is, if it’s only small parts you are cleaning, get a glass jam jar and fill it with evaporust or petrol put your parts in it then put that into the cleaner and run it. Watch as the jar and contents will displace a fair bit of whatever solution you have in your cleaner. The neat fluid really gets into the dirt and contains the contamination in the jar. HTH.

The bike is 1983 so not quite historic status yet.
Thanks for the replies I’ll just leave things as they are and mot it next year once it’s all sorted. Just running issues rather than mot fail problems.

Have tried to find information but not had any luck so far.
I have a bike that is currently taxed and insured until next June but the MoT has run out. It needs work and won’t get used until next spring so I won’t be renewing nor would it pass an mot at this time. Do I have to declare it Sorned because it has no MOT? If I do then I presume the road tax becomes null and void but I guess that because it’s only £20 I doubt there would be any refund. However if I got the bike back on the road early next year and I didn’t declare it sorned then the road tax would still be valid. It’s only a few quid I know but seems a waste to have to retax it next year.

Hi all I’m hoping someone on here has or knows someone that has a CB125 superdream and maybe has either a good spare engine or specifically a complete cylinder head that they don’t need and would be willing to sell.
Mine is in a poor state and it would cost too much to fix what needs fixed with replacement parts. So looking for a top end but would take a full engine if available and at a reasonable price.
Thanks Alan

Your compression readings look a bit low to me are they done with the throttle and choke wide open.
Yes full throttle no choke, didn't think they were too bad at 120/130 but not sure what I could do to improve it maybe some oil in the bores and redo the test to see if that brings them up at all?

Hi John thanks for your reply, Yes it's twin carbs.
Forgot to mention that I've stripped and cleaned the carbs twice, in an utrasonic cleaner, also got a second set of carbs and swapped jets around to no effect. Looking at the jets all look clear and no obstructions.
I had similar thoughts to the leaky airways and have tried spraying WD40 all over the carb rubbers with no difference to the running
I've also tried a 2 into 1 inlet manifold from a CM200 and can't get it to fire at all with that.

I have an 83 cb125tdc superdream that despite my best efforts I cannot get it to run properly.
It has decent compression 120psi LH cylinder 130psi RH cylinder, and has good spark on both plugs, valves all adjusted correctly and timing marks all line up.
When I try to start it from cold and on the choke, it turns over for ages before it fires, when it does it just about explodes revs straight up to 6/7k revs then dies as soon as I try to back off the choke. Sometimes it will run thereafter after a lot of turning over again but there is a noticable weakness on the right hand exhaust compared to the left and right runs hotter than the left.
I'm lost for ideas what to check next Looking for some guidance on what I could check next to get it going again.
Thanks
Alan

Can I politely ask how much the refurb costs? I'm thinking of doing mine and have a complete overhaul kit from 4into1.com but I'm thinking of farming the refurb out rather than tackling it myself.

Thanks all for the replies some good advice as always. I’ll start with the plugs and ht leads got a carb rebuild kit sitting waiting to fit but need to clean up the garage and make some working space before I tackle that.

My bike doesn’t get a lot of use but generally always starts on the button, can be a little rough running initially and occasionally runs on 3 cylinders for a while till it warms up and then kicks in.
I was thinking an ignition swap would maybe smooth things out a bit and was looking for any thoughts or recommendations on any particular systems. I’ve seen a wide variety of kits and prices and are they a “you get what you pay for” type upgrade?
Cheers Alan

Is this what you need John? The rubbers are no good but everything else is fine, if it’s any use to you, you are welcome to have it pm me if interested. Alan
