leaking oil lines gs750

[Guest]

Have a 83 gs750e and the oil lines from the crank case to the cylinder head appear to be leaking around where the fittings are crimped on, any one have another source for them other then 65 a piece from Suzuki?

Ok, mine have no cooler lines, but here's what I will do if I decide I need a cooler. I'll go along to the nearest industrial hydraulic hose stockist and ask them what fittings they have. Much cheaper than off the shelf OEM parts, unless you luck into some new old stock.

You have a top end oiler on your bike? Pics? Okay never mind, just looked at the fiche. Thing is, partsoutlaw doesn't even show them available.

huh, bikebandit.com shows them availble, might half to go somewhere and get some made or nos or get lucky on used ones that don't leak.

everyone is forgetting your 83 750 has a lot more oil pressure unlike a roller bearing engine.
some braided stainless lines would look quite good on your bike

Have you tried any hydraulic shops that make lines yet? If they don't have the same ends in stock, they can usually re-use yours.

I know they show them, though what's odd, when I looked at the exact same parts fiche last nite, there was no price listed, that usually means that part is discontinued. Now I look at it again tonite and there is a price listed...weird.

theres quite a few motorcycle/quad speed shops around here, I will call them up see if I can get some braided ones made.

I was directed to goodridge as a potential source for making the parts up, when I was looking for the same lines for the 550es

Ermm... hydraulic hose sneers at a mere 75psi.
I should also add - hot oil tolerant hose is commonly available too.
As I said above, my first port of call for cooler, external filter, or oiler hoses would be an industrial hose stockist - get somebody that knows their job and they'll steer you right and for half the price of OEM parts. Of course, fancy-panty SS steel external braided hoses don't usually get much of a look-in on skidsteer or Cats, but you never know...

Google anPlumbing.com I ordered my lines from them, mine were AN-6 order a 3 foot hose and cut and get the adapters you need.

Lots of confusion in this thread about the oil lines in question. The 3rd generation 750 engine transports oil to the top of the head via external oil lines that run up the back of the engine. These lines are totally different than those moving oil up and back from the oil cooler. These lines use two different sized banjo fittings, which complicates replication from standard parts such as Goodrich and/or Earl's parts.

Salty Monk (Dan) went through the process of trying to replicate the lines so someone might want to ping him. Can't remember what he did but using a hose shop is a possibility.

has the OP confirmed that the lines themselves are leaking; not the crush washers? like the ones used in brake banjo applications they are dead soft copper and will work-harden when re-used, and will not re-seal
