Hi Dan. 
Thanks for the direct ask. As top fuel has said. Most probably the output shaft seal behind the engine sprocket that is leaking. You may have to do a bit of de-greasing about that area to spot the leak and even take off the sprocket to tell for sure it is leaking. A new seal can be inserted from the outside. A repair shop should not charge you too much to replace it, or get yourself a workshop manual for the beast and have a go yourself. Happy to talk to you more about it. Good Luck.

Fuel leek from the carbs overflow


Hi, Neil and the usual suspects are:
1. Damaged or restricted fuel tank venting system.
2. Loose float bowl screws.
3. Damaged float bowl o-ring.
4. improper fuel level in the float bowl.
5. Worn or dirty inlet valve or seat.
6. Damaged or leaking float assembly.
7. Particle contamination in inlet fitting cavity.
Good luck and have nice a day.

Flooding xj900


Hi I had the same problem after rebuilding my CB900 carbies a few years back.

The floats hang down so far in the carb that they actually get stuck down even when the fuel flows in after a rebuild.

Turn the fuel on and tap the bowls with the handle of a screw driver (plastic) I used a long shaft screw driver that way you can pretty much get all of them from one side.

This light tapping jults the floats and it allows them to pop up with the pressure of the full bowls if helps with them moving.

Hope this helps.

Restoring a Yamaha SR125


well to start you need a new engine gasket kit. then take top end off and check rings and piston . Take carb off and check lines which the fuel line will need replaced. The carb will need tore apart and soaked in some kind of carb and choke cleaner or b-12 chemtool. But not the floats dont put them in there take air gun blow jets out and take them out and do it again. valves will prob need cleaned. Spark plug replaced . etc etc general rebuild with carb cleaning and fuel line replacement prob looking at 200-250 bucks and it is really not that hard to do. and make sure you clean gas tank out good and replace fuel filters out from in tank and if in the line it too. And replace oit and oil filter if there is one.

How to remove oil from a yamaha SR125


Hi Amalia
Not too hard to get the excess oil out. Easiest way is to tip the bike on its side with the oil fill bung out, and drain off some of the excess via there.  The only other way to do it is drop the oil entirely and start again with fresh oil(dont reuse it even though it is new). Gets really messy trying to put the sump drain bung back in with oil pouring everywhere. You also stand the risk of getting dirt into the engine, so i Dont recommend draining off the excess from underneath.   Dont run the bike with excess oil. The site glass is fitted from the inside of the casing, and is rather hard to clean. They get dirty from a build up of clutch friction material settling on the glass. You have to strip the motor down completely to do that. Hope that helps you solve your problem. Happy to answer any questions you may have. Riding bikes is so much fun...cept when it rains!!   regards robotek
