IRK:

Are those 10mm to AN adapters in the caliper and M/C?  You can also get hoses made up with metric straight end fittings.

Yes, they are.  Seems to be cheaper to go with the metric to AN fittings and Russell DOT hoses.  I'm spending half of what it costs for Galfer or Venhill.  I don't think Galfer even does anything but banjo hoses.  And Venhill does the same as the Russell hoses with an AN fitting to a banjo.  I'd be interested in someone who does a line with a metric fitting to have the line be one piece.  I haven't found one yet.

Spanking new pistons and cylinder block with the machine shop, and while it's there they're doing me a solid and fixing the busted fins too for a good price.  Once I haul it back to my garage I can finally empty the cans of satin black paint that have been sitting on the shelf for two months onto the thing.  It might actually start to look like something.

Youíll have to show us some before and after shots of the fins Iím interested to see how they come up. Are you going to run the same cams now that youíve gone to 823cc ?

There are suppliers on ebay that will make them up with almost any normal end fitting.  I have had them made with female 10mm and male 10mm.  There used to be a place in the UK that had the most amazing options of end fittings in anodized aluminum or steel, straight or banjo.  Fren turbo do teh same (or used to) but a bit expensive.

I have bought a bunch from this ebay seller.  Only issues were where I measured wrong and can't really blame a supplier for my screw ups.  http://www.ebaystores.com/Rennsport-Auto-Parts

This 3AN is new to me...is 3AN the male and -3AN the female?

3AN is short for -3AN. AN stands for Army/Navy the 3 denotes how many sixteenths of an inch the ID of the tube is, in this instance -3AN is 3/16" ID a -4AN is 4/16 (1/4") and so on. Its worth nothing that this size is a nominal value, tube ID is often smaller than the stated size. IIRC the reason AN fittings were developed was to standardize lines across a large variety of machines, reducing the need for proprietary lines.

I personally like the Goodridge lines, which are for use with banjos. Ive setup many bikes with them and the lines are pre-fabricated  and sold in a variety of lengths.

Thanks Doc for the expanded info on the 3AN fittings and teaser for the link.  I'll look into my options some more and then decide, but I've learnt a lot more than I knew last week about brake lines just from your last few posts.  Cheers fellas.

cb250nproject - I have some CB 900 cams that I'll be installing instead of stock.  The situation was kinda fortuitous (for me anyway) but 900 cams are mine nonetheless.  I'm told they're a simple drop in - just need to check for any clearance issues that I may have between the cam lobes and the head.  That's on the to-do list.  Right now I'm waiting on the machine shop to finish up the cylinders, but this weekend we're doing a market down in Toronto so tools are sadly downed for the next few days.  Sucks too - it's the first bit of dry weather we've had in what seems likes weeks, so the KLR's gonna have to fidget until I'm back.

You can buy all of the Goodridge fittings and line (Amazon lists them) and make your own to length/clocking/end type. I used their small line and banjos for the upper front on the Hunley. The line is no bigger than a throttle cable sheath.

Remembered that it was recommended to check clearances on the CB900 cams I'll be using.  I bought a valve spring compressor tool off amazon for $35 (and saved having to ask my long-suffering mate if I could borrow his tools again) which had one job to do and did it perfectly.  Out came the valves, dropped in the 900 cams and they fit just fine - no clearance issues.  Apparently these cast heads can have slight size differences in some areas and it's a good idea to check even though 900 cams are a straight swap -



Looks like no drama in that dept so got the valves back in (with some more assembly lube) - hoping to get my newly-bored cylinder block back from the machine shop soon and this lump's gonna get painted.  In the meantime - Ottawa for mother-in-law's day.
