#1:  blue oil line-SOLVED Author: crow Post Posted: Sat Jul 03, 2010 6:04 pm

put 1100 kms on the bike since I bought it and I think I'm noticing increased blueing on the rear cylinder oil line. It was a bit blue near the top bend when I bought it and i figgered it was just because the line sits pretty close to the jug but now I think there might be might be a problem. Is there any cause for concern here and if so what should I do?Thanks.

Never heard of an oil line turning blue . . that's usually reserved to the exhaust.
Got a pic?

make sure that your oil filter is installed correctly...the hole should face away from the engine toward the person installing it

Heat like that in the head area could be generated if your bike was running super-lean. That would also be very hard on the engine components. Check your plug color; black and/or wet means too rich, stark white means too lean. You want 'em to look sort of gray or tannish-brown at the insulator.

Plug looks like it's not running lean, maybe a little rich if anything---I made the switch to the Autolite AP63's and have been very happy with them. Could be the blued line was a one-time occurence with the previous owner. I wouldn't worry about it too much unless it gets much worse or you start hearing ugly noises from your front jug. Just keep an eye on it.

Crow - wrong plugs - should be bp7es or bpr7es, and this is covered in your other thread!

might want to check the line for oil delivery, just to be sure (loosen the oil line bolt a bit while running & watch for oil coming out)

It looks like that line is missing the rubber piece that prevents the line from touching the cylinder head. It's probably why it blued.

good eye, Imac!

How about rear jug ?

Attached picture shows what Imac refers to.

Great eye, Imac, and thanks for the pic, Jake. My oil line sits about 1/8 inch from the top fin and about an inch away where the rubber should be. It looks like its shaped slightly differently from Jakes and positioned closer to the jug and farther from the intake.PO must have bent it ,bike shows evidence of being laid down on that side once.I'll try to reshape it away from the jug so its more like Jakes and make a spacer until I can find one.I think you guys have solved the mystery of the blue oil line.Thanks a bunch.

ok I put that line back where it should be and with the ap63's gapped to .028 she ran real nice and didn't get nearly as hot.Gotta love this forum! Thanks again for the help,amigos. XV1000 blue oil line-SOLVED
