Okay, so I did an oil change today. 200miles since getting the bike on the road, figured I'd get rid of the sludge from the previous owner. Then I had a stupid idea:

Why not get rid of the rotten midsection of the oil cooler pipes at the same time?!

I copied some guy on the internet somewhere - hacksawed either side of the flexi, slapped some 10mm fuel line in and a jubilee clip at either end. Completed oil change, ran the bike for a bit and all looked good.

2 miles down the road my back brake stops working and the oil light comes on.

So... Anyone successfully done this? The only replacements on ebay are shabbier than the horrors I already sliced up.

Have you tried to replace jubilee clips with something more strong, like clips for pneumatic hose? https://www.hcl-clamping.co.uk/double-e ... ?quickview

I think that your problem are those clips. Try here. http://www.brammer.co.uk/hose_tubes_duc ... ucting.htm[/url]

Hi mate,
Recently done my '98 N
Used 10mm I.D. Stainless braided hose, and 4 Stainless clips, bolt type not Jubilee.

Cut the rotten original swaged clips off, if possible dont destroy the swaged collars on the steel pipe.
Unbolt pipes from the cooler end, work the pipes / hoses off leaving the bottom sections connected to sump.

Cut 2 lengths of 110mm of your chosen hose, bit of grease to ease them on metal pipes so the clips can bite behind the swaged collars on the pipes.
Refit in reverse order as they say.
It's not how old you are, It's how you are old.

Thanks for the replies!

It looks like I screwed up in a number of areas - first by hacking the middle out with a saw which cost me the original collar/lip, then by using the wrong clips and finally by using the wrong hose.

Rather than have the bike in pieces while I figure this out, I found a shorter union bolt for a few quid and finished the oil change. I'll take your advice and rebuild the hoses correctly, probably will have to braze a 10mm olive on to make a new lip.

Cheers!
