The down pipes have a collect manufactured on the end where the silencer butts up to so would have to trim the silencer. ☹️

Anyone had a problem with the DS pattern silencers for the CB250k3?

Mine seem about 5mm too long in that when mated to the down pipes the mounting holes are 5mm further back than they should be and can not get the mounting bolts in.

They are pushed on as far as they can be onto the down pipes, so may have to trim a little off at the connector end.

Any ideas

Thanks Ash, it’s almost done.

The paint work is all NOS parts. Took me awhile but worked out only slightly moe expensive then a respray but I can say it’s all original Honda paint 😉

That chromeon yours looks the business. I paid £140 for just the rear guard I got from you to get plated.

Ok nearly there, quick update and should be all done in a couple of weeks 😀

Engine back in and now starting to put the back on. My box of parts is emptying nicely

Just had my camshaft and rockers for my cb250k3 refurbished/reground by Brendan at the Common Motor Collective in Houston Texas US.

Including return postage £219 + £18 vat, cheapest price I could find, though someone will probably tell me different 😉

Great service recommended 👍 does take about month to turn around.

Tricks & Tips / Re: Cylinder seating cb250

Ok, have had the barrel off again checked seating of dowels and dimensions of dowels and all ok.

Measured gap between base of cylinder and cases with feeler gauges and found to be 1.2mm. Can slide Althea way through until I can feel the O ring at base of cylinders. Took barrels off again and found that the o rings stand 1.3 b 1.4mm proud of the cylinders.

So my conclusion is the gap is caused by the O rings and should disappear when all is torqued down.

Comments welcome.

Hi all,

Finally getting round to rebuilding the motor on my cb250K3.

Quick question, just fitted the barrels and they do not seat all the way down onto the base gasket. Have lifted up numerous times to check what could be hanging it up but can not see anything.

It’s only sitting proud about 1mm, am now thinking it’s the o rings at the bottom of the cylinders.

If that’s the case this means it won’t close up until I torque everything down, also will this effect the valve timing once set prior to torquing it all together. 🤔

Any ideas.

Cheers

Looks like the Keyster KH1200F kit may be the one! But I take your point have found that on several items I’ve bought ☹️

Tricks & Tips / Carb identification

Just about to rebuild the carbs on my CB250K3 1971 and found that the carb kits, Keyster KH-0120F, do not fit my carbs!

The keyster kits are the ones listed for my model and year of bike but they are clearly not right.

This makes me think I have the wrong carbs.

Can anyone confirm what carbs I should have? The ones I have are Keihin 725B.

Many thanks

Thanks James that would be great 👍

Have seen a few “universal” fitting kits but would probably end up wasting my money.
