So I'm considering an ork. It looks like all that is available these days is Baron's. That's probably OK.

Question is this; All the listings say "#8 lines for ideal oil delivery equal to or exceeding factory specifications". First of all there is no factory spec for this application. When they say #8 are they trying to say 8mm (m8) or are they just trying to obfuscate? Or is this some hitherto unknown measuring system?

Thanks for any input.

Have you checked the KB?   V-Star 1100 Wiki Knowledge Base - ORK's and Oil Coolers (google.com)

Yes I have. That's why I'm concerned about what "#8 lines" means. I suspect they mean to say 8mm which is around 5/16" and should be OK. The info in the wiki is quite informative and valuable but a bit out of date with regard to what is currently on the market.

I went ahead and ordered one. I'll measure the ID of the lines and if I don't like what I see send it back. I'll post my findings in case anyone else wonders what #8 is.

In any case I don't see how they could meet or exceed manufacturers specs when there is no such thing.

Thank's for the reply

The 1100 I recently purchased has what I believe to be a Jardine ORK. Not something I would purchase but since it's there I'll keep it. If I keep the bike and start modding I'll cover it with a chin scoop

Package arrived already, less than 2 days. I don't think I want to take it apart till I'm ready to install in march but outside diameter of the braided lines is just over 10mm. So ID should be at least 1/4 if not 5/16.

there is no issue with the stock oil lines ... I've been running 70,000 on them stock and semi modified, and fully modified  @ 8000 RPM 38 lbs psi .. where the issue is .. how low you go with rpms 900 @ 3lbs on my gauge .. 1000 @ 10lbs..
