For the measurements tolerance I was going by the Honda workshop manual which only shows the specific ranges in 2 decimal places.
If it needs more precise measurements I will have to get a better micrometer or as you suggested Hairy find an engineering shop who can measure beyond 2 decimal places.

Thanks Julie.

The machine shop said they match the bore to the piston and then mark the pistons accordingly.

One more question, my crankshaft has no markings to indicate the journal size but I have measured each one with a micrometer and they all measure at 31.98mm and the crankcase is marked as BBBAB.
Can someone confirm what crankshaft bearings I will need please?

CB350/400 / CB400 Rebore question
« on: June 24, 2018, 09:07:25 PM »
Hi all,

I am getting a 0.5mm rebore done on my 400F and have a Cruzinimage piston set.
Is the piston clearance .001 inch as there are no guidelines supplied with the pistons?

I am thinking of taking the work to be done at HT Howard in Slough, anyone used them?

I bought the new speedo drive seal in Rochester on Friday but not from BearingshopUk as they had none in stock but on the proprietors suggestion form a seal shop in the same industrial estate.

Old seal on the right and new seal on the left.

K2-K6, moved from Wimbledon to Raynes park when I was 7, we lived just off Grand Drive.

Did not know there was an Aprilia dealer in Raynes Park, used to go to Frontiers in Wimbledon Chase also Elite Motors, Garratt Lane Autos in Tooting , Mocheck and Gus Kuhn Motors in Clapham.

All the old bike dealers from my youth have gone now.

Yes that is the seal.

I want to strip and clean my speedo drive but if the seal gets damaged when removing it I would like to be able to source a replacement.

I have tried to remove the seal but it seems to be stuck fast so might get damaged.

Does anyone know a part number for the seal that goes onto the speedo gearbox?

Hi,

The trip reset knob unscrews, I restored both the tacho and speedo with new glass and dial faces, fitted a grommet to the reset knob as mine did not have one fitted.

Hold the inside of the shaft and unscrew I am fairly certain that it was a left hand thread and is loctited on.

Don’t know why the photos aren’t orientated correctly but come out correctly when they are clicked on?
