Misc / Open / Re: eBay promotion --New non-PayPal payment

Thanks for that Allan... looks straight forward enough. Hopefully won’t happen now as the buyer has contacted me and arranged collection, and offered to cover the costs... which I have agreed to split with him...
Nice RD on your avatar by the way! Here’s mine 😀

I’ve just sold an item, marked as collection only, to an idiot who has immediately paid through ebay even though he is going to have to collect the items in person, thus costing me £12 in fees for no good reason. What I am wondering now is, if this idiot thinks i am going to post this item to him and then realises that it cant be posted and decides to cancel. If I have to refund him how does it work? Do i have to refund the full amount leaving myself out of pocket, or is the fee cancelled in such circumstances.. Ebay do not allow you to prohibit electronic payment in the first place, only they can manage the payment methods...

Sorry to read your news Andrew, i can only imagine how you must be feeling. Taking your time sounds like the right thing to do. Best wishes to you.

Peter James for me too.. at the moment they seem to have the best classic multi bike premiums. Before them I was with Footman James but their premiums started to rise....

2 stroke very difficult to diagnose. Running worse off choke suggests it may be too lean but could be something else. My advice re 2 strokes is always to start with the basics before leaping to diagnose major problems such as crank seals.. Start with the basics, new plug, fresh fuel, strip and clean carbs and all passages thoroughly, make sure all settings are correct, jets clear, float height correct. Then you can move onto compression testing and then onto crank pressure drop testing. Do you have a manual for the carb settings? You’ll need one. Good luck with it, be careful cos if you get it even slightly out things can go wrong very quickly...melted pistons etc.

CB750 / Re: Bent steering tube.
« on: January 18, 2021, 09:35:26 PM »
Cheers! and good luck with the replacement johnny. When my replacement came it looked ok but i noticed on close inspection that the lower race was cracked (as it was on the original stem) and the distortion was right at that point where the race fits on the stem, as with the original, so not easy to detect until the race was removed. All the weight of the bike is basically loaded onto that lower race and I don’t know if its long term forces that gradually distort the stem or a single impact. The low milage would be an argument against that, but then the usa users possibly spend more time riding on unmade roads in certain districts....? I guess it doesn’t matter how it happened but I am a bit concerned that the metal could be stressed, it looked ok but who knows. The material Honda used would be tough and not prone to fracturing but those properties also make it slightly soft and therefore able to distort under load... Its a job I need to tackle before the spring... My brother has a little myford which is handy as I am a turner by trade but don’t have my own lathe... but the lockdown is keeping me out at the mo.

I have a similar issue on my K4... the stem is not bent as such but is slightly distorted right at the base whee the lower race presses on. I did buy a spare when I was doing the resto but that also has a very slight distortion in the same place. The bike rides great but i can never get the bars to be pointing absolutely perfectly straight which I suspect is due to this. I obviously don’t know how this happened, whether it was due to a minor front end (no other evidence of this) or whether its just wear and tear, usa dirt road riding, whatever.... The stem tube walls are fairly thin and would probably be fairly soft material too. As I have a spare lower yoke I am planning on turning off the lower weld and making a replacement stem to press back in. You can buy a modern replacement from a place called cognitomoto.com but they are ridiculously expensive.. Anybody with a small lathe could make some, they could probably make a few bob selling new stems on here. 😄

I always liked the look of these bikes, nice and compact and nice colour scheme. But I always thought that they just didn’t warrant the “CBX” moniker... more of a modest sports tourer than a sports bike, but great looking.

CB350/400 / Re: No Vacuum on Carb#1
« on: January 12, 2021, 07:39:24 PM »
Sounds a bit worrying, if there is no vacuum that means there is insufficient movement or air through the cylinder which could be damaged, bent or burned out valves or missing, broken or stuck rings or a holed piston.... you should be able to get an early indication of the situation by putting your thumb over the plug hole and turning the motor over.

Misc / Open / Re: Exhaust gas analyser
« on: January 09, 2021, 04:55:19 PM »
It could be done but the best way to analyse the gasses is to put it on a dyno, preferably somebody you know and trust and is into his classic bikes. You need to analyse the gasses at various engine loads and speeds to get it right... I recently had one of my classic 2 strokes on a dyno, the level of info and setup that can be achieved is amazing... there’s no way you could match it with traditional tuning methods. Fortunately the dyno belonged to a good friend of mine who specialises in setting up classic 2 strokes. I was never keen on the idea until i finally bit the bullet but now I am a massive convert.

And the 2 strokes still had more than a decade of astonishing development and exciting biking in them before finally being phased out... starting with the iconic LC and then it’s YPVS derivatives before finally bowing out with the parallel twin TZR’s in the UK... By that time the R1 was in the pipeline so not much reason for Yamaha to be sulking as far as producing exciting performance motorcycles is concerned  ;) ;) ;)
