98 DS80 oil mix leak

[leirhiht]

hi everyone, its been a while since ive been on the site and since I last even rode and now im trying to sell my 98 DS80 after I get it fixed up and running. ive already cleaned the carb and I noticed a decent leak of oil coming from the oil mix hose and has pooled on to the top of the engine. maybe there is sand stuck in the hose or something I do plan to clean out the whole reservoir but I am seeking advice on how to clean the hose out the best. especially the one going into the casing.

i was going to post pictures of the leaky hose that comes out of the engine casing and feeds into the carb. but I guess it has been a while since ive been on the forum it is not allowing me to.

hopefully my description is good enough

ok I figured out the hoses go into the oil pump. assuming there is sand in the hoses what is the best way to clean them without getting sand into the pump?

I wouldn't bother trying to clean them honestly, if one is leaking it's likely got a crack or split and your best option is just to replace them. Finding such tiny tubing without buying OEM (if they are available) might be a challenge... perhaps some rubber vacuum line tubing would work.
If you really want to clean them you'll have to remove the lines completely and try to blow them out with compressed air or some sort of solvent.

Ok cool I'll try that but one thing I was concerned about is possible sand in the injection pump. Or should I even worry about this?

How would sand have gotten into the oil system? The pump can probably be removed, disassembled and cleaned also if needed but unless someone dumped sand into the oil tank it would be very difficult for it to find it's way in there.
