    Hello,

    I'm starting work on a pretty beat 400cr. First up I know I'll need a piston and possibly a conrod and crank. Somebody left the carb off and I can see the piston rusted inside the intake port. Not sure about the rest as I haven't got the barrel off yet. I'm planning a full rebuild anyways.

    Is anyone making replacement pistons? I looked on the wiseco site and they did not have one.

    What other engine parts are hard to source? I'm hoping bearings are standard sizes that I can get from a bearing shop.

    Also, is there a good manual for this bike out there? I'm in the US and can't find anything except some Clymers on ebay, but they come from UK. Is the Clymer worth it?

    Thanks for your help!

    Better than nothing ! The parts list on this site is a great source of info. There does not seem to be a workshop manual there though.

    Thanks! Didn't know to search for MK & ML. This is my first foray into old husky's. What about pistons?

    John doesn't list all the stuff he has on the site, but call him. He had the piston for my 400 in stock last summer. Good guy to get advice from also, phone # listed on his site.

    Are there specific tools I'll need to pull this motor apart? Other than a crank puller, and typical tools. I know the manual calls out a case splitter, but is it needed?

    Couldn't agree more steve,

    John has been an invaluable source for the engine stuff mine has needed, he's not the cheapest guy around but i'm not bothered about that because he always helps out with advice when i call, he's running a business, time is money so i support his business buying what i need, he supports my build helping me with the advice i need to move forward.

    The clymer manual is a virtual reprint of the factory one, i have both and they're both pretty vague, but it's all there is so take plenty of photos and make lots of notes as you pull it apart, i was a vintage virgin before i started on my '71 but the guys here have been super helpful, get a good supplier on your side like john and you will be fine.
