Preventing Oil Leaks

When it's time to check your valve clearance be sure to replace the inspection cap o-rings. These get hard eventually begin to leak oil. The oil gets on the cylinder, runs to the left side when you park and will slowly bake on. You can't see it very well while the GZ250 is on its side stand. Once the oil gets baked on it is very difficult to remove. Both of our GZ250's had this type of leak. I have seen photos of other Suzuki motorcycles with the same engine that had the same oil leak.
