buzz 50 excess oil trouble

burge · 10-25-2014, 06:18 PM

Originally thought engine was sucking oil from gearbox but now realise gearbox is totally seperate so am now suspecting there might be a seal behind the self mixing pump that is leaking and keeps fouling the plug plus blowing excess oil out of exhaust , I'd prefer to keep the self mixing system has anyone else had similar problems

It could be sucking gear box oil though the crank shaft seal...
First check that the injection pump is adjusted correctly...

Gday
Pete , the gearbox is totally desperate , as in 200 km away so no chance of that being the problem , have had bike for 10 years so I wouldn't expect the adjustment to just go out

OK..........................
So you have not checked or adjusted the pump settings for 10 years....

Do you think it maybe over-due to have a look...?

you are right..things usaly don't " JUST GO OUT"
it's a slow process that started the day you bought it
and it's finaly got to a stage where it efects the way it runs...

If this is the issue...

I agree Pete , things do need adjusting over a period of time but this has come on suddenly ,have checked the cable and mechanism and all seems good ,the bike is still using the same tank of oil that was in it when I 1st brought it new ,so bike still like new , sorry about first message I typed seperate and 200mm apart stupid spell check

Seem to have sorted problem . drained oil tank and refilled with new stuff .took girls for a 3 hour ride and no problems . still some excess smoke when warm but am thinking it maybe excess build up in muffler as it is getting less

I recently saw an alarming pic on a two-stroke Suzuki forum. A guy cut the header off of the expansion chamber, and the passage was almost totally clogged!

You can clean the exhaust by removing it and throwing it a fire pit or burn barrel until it stops smoking. I can't do that in my area, so I clamped one in a vise outdoors and slowly heated it with a torch. It took a long time, but it worked great.

thought about burning it out but its going well again and is not a real issue so might let it be for now
