Thanks for the responses.

The repair kit requires engine removal, cleaning, then drilling and tapping a hole to accept the M10 insert? Whether it works will depend on the degree of damage to the case, which is not clear yet. However it is more than just a stripped thread, so some repair may be required first.

I have sourced some cases from Steve Cooper - https://www.400fourbits.co.uk/. There are two sets: one set can come with crank, bearings and rods for £175, or £120 for cases only; the other is cases only, requires the same repair that has been mentioned and goes for £85.

I think this might be the best route for me as I would have to get someone to do the welding and drilling for me and I’m sure that wouldn’t be cheap, if I can find someone.

I know on the CB750, the cases are matched but I can’t remember if they are paired with the crank; is it the same story with the 400? Can I just get the cases and then fit my own bearings and crank, assuming they are OK.
The engine number on this set is 1015*** while mine is 1084***; no problems here?

I’ve looked at Philpotts and the cost is £195 to rechrome the pair. DSS sell repro legs for £95. Anyone have any experience with these?

Hi Guys,

Thanks for the thoughts. I got the retainers taken out at a local shop; he machined them out from the hubs and just removed the retainer from the sprocket flange. Have to check now if the threads are OK; that could be the next issue.

On the forks; in Zimbabwe at present there are only people specialising in rip offs!! I can't get even normal chroming done here as they do not have the materials. Most specialist things I send "down south" as they say here. I see CMS or david silver (forget which) have fork slegs available - bit steep at 300 Euro or something, but may be the easiest option.

Stay well

Sean

Hi All,

Having restarted my stalled rebuild, I encountered some diffs . Help appreciated!

The bearing retainers on both front and rear (wheel and sprocket flange) wheels are siezed solid - even my attempts at destructive removal failed. Rather foolishly I sent the wheels to be rebuilt and rechromed with the bearings intact, hoping I think that the guy would remove them before doing the work - he didn't and I am now reluctant to apply too much heat to my shiny new chrome. Would the rechroming process have helped in the seizure? How can I get these off?

Problem number 2 relates to the fork legs. These were so badly rusted and pitted at the top as to be unsalvageable. I got a set of forks from a 750F super sport. Now these area bit longer than the originals. Can I use these safely?

Thanks for your thoughts

I am restoring a 1974 K2. It is blue and I am trying to identify the correct paint colour, and a source of same.

I think it might be \"Planet Blue Metallic\".

Anyone got a part number and a source?

Thanks
