CB350/400 / Re: Buying large amounts of parts from yamiya or impex

I've only ordered from Webike in Japan. I have yet to be clobbered for tax/import charges. Service has been excellent. Some parts, however, are cheaper in the UK....

Yeah, I've spent my lunch hour putting together a spread sheet comparing prices, most are cheaper on yamira but a few are cheaper or negligible on DSS.

Some stuff is half the price from yamira.

I'm assuming you have put a Brown shell in number 2 main journal - if you have ruled out crank ovality might be worth tracking down a pair of black shells to reduce the clearance so it's more on line with the others.

I've sold all my spare black shells but a member here might have a pair they are willing to part with - worth a try.

Got around to measuring with my brown shells, it goes down to around 0.025mm, so I'll just replace that green with a brown. That means it will be BBGBB, but could I get away with BBBBB? I'll measure again trying a brown in the middle main.

Ordered quite a few times from Yamiya inc bearings when I was doing the 750.
Always worked out cheaper than silvers even with the postage and capture charges.
This has always been a gripe of mine that Silvers are ripping us off.
Sure Trigger or nurse Julie will be able to offer more info as they use them all the time.

I've ordered from impex and that was fine and I didn't seem to get any customs charges unless its in the price.

What do you mean by capture charges?

Ive bought my bearings from yamiya and impex because even with expensive postage its cheaper than DSS.

I've been comparing the prices on yamiya to DSS and most of the parts are almost half the price. Has anyone ordered lots of parts from yamiya? Whats the postage and tax been like?

Out of interest which journal number is it?

From the generator/stator end its number 2.

Miss type, its 0.038mm :D

I guess its just because I got a reading 1 thousandth less than the other ones. I'll remeasure and do another plastiguage check.

I guess as long as its between 0.02 and 0.05mm it should be fine.

One of my mains is giving an odd reading, its 0.38mm when the rest are 0.025mm.

Can I assume the clearance is fine if its within the wear limit of 0.02 or 0.05mm?

How close it too close?

CB350/400 / main/big end bearing size differences

What are the size differences for the bearing, i.e between brown and green?

Or could someone point me in the direction of some documentation?

Bearing clearance update 2.

From the generator side first:

brown 0.025mm green 0.038mm green 0.025mm green 0.050mm green 0.050mm
                                                                        brown 0.025mm

I put the brown in one of the green that measured at 0.050mm and it went down to 0.025mm. I'll remeasure the one that gave a reading of 0.038mm.

I think the best thing to do would be to go BROWN GREEN GREEN BROWN BROWN.

Then as other people have said, run it in carefully.

Here you go, this is where I bought mine. Very quick delivery as well.
https://www.ebay.co.uk/itm/264575277700?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=J-zL353uSQe&sssrc=4429486&ssuid=5XpGce3OSuS&var=&widget_ver=artemis&media=COPY

Thats the size I originally used. Ted recommended going smaller to 0.025 to 0.076 mm. Which only seem to be sold in bigger quantities or are from the US. Luckily Ted had some spare which he kindly sold to me.

Working through measuring them now, got 3/4 of the way and my electric ratched went flat. I don't fancy fully tightening and undoing 10 bolts over a dozen times each :D

Would it be worth getting a smaller gauge?


Where did you get it from? I can only find big boxes of it that are £35+

Someone on this thread said green so I got 0.007″ to 0.020″ (0.175mm – 0.500mm).

I didn't realize there was a metric scale on the other side until I measured 4 of the bearings, I'll have another look. Can I just match the same 7 reading location on the metric scale?

Update.

My brown and green bearing sets arrived from impex. Took a while to get them on their end but only took 5 days to arrive from Japan which is crazy.

Pictures of plastigauge measurements here: https://imgur.com/a/WOXySvp

Ive noted which one is brown. They are all 7 thousandths or less, except one which I will measure again.

From looking back at the chart could I change the greens to browns or would that be too tight of a tolerance?

Out of interest does number 2 mains journal look visually different to the others in any way?

Gave it another clean today and remeasured it, it measured similar to the others, I think it was just still dirty. All the main journals look pretty much the same.

When you say the clearance is 0.01124, do you mean the crank measured 31.98876?

Yeah, the figures I gave are just the clearance, so 32 - whatever the measurement was.

The 2nd measurement was a bit odd but the measurements I got from measuring it in a few places was 31.98368mm 3 times.

The way I read the chart was like this. First code is B so the crankcase allowance row B, then the clearance is 0.01124mm or 0.011mm so its the - 0.010 to 0.020 column so BROWN.

Actually reading it out loud and typing it, it should be 1 BROWN 4 GREEN.

I'll order 1 set of green and 1 set of brown and measure with plastigauge.
