Hi I want to look at topping up my 4 speed gearbox on 93 Bullet 500. I noticed some oil dripping from the drain plug so tightened it and the leak seemed to stop but I dont know whats in there or its condition. I am confused as to what to put in there I have seen a youtube video of a guy warming up a concoction of snotty grease on the stove and squeezing it in but have read posts saying just to use engine oil or thick gear oil but not EP90. Some posts say to use synthetic oil but knowing my bikes tendancy to leak, grease seems like the best option. I have looked up Veedol but all that comes up is old antique rusty tins. Has any body tried Shell Gadus grease I have seen tubes of that available. Also some people say to add black molly I have a tub of black cv joint lith molly grease is that the stuff? Will general purpose grease be ok I have a tub of that as well.

Sorry for the double post it was the back button.

If you are only topping-up, use any grease that you have. If the gearbox is being stripped and cleaned out, I would repack it with an EP grease similar to Shell Alvania EP OO or EP 2 (Extreme Pressure) which are designed specifically for heavy-duty gearboxes. If you would prefer an oil, 140 gear oil is similar thickness to a diluted mixture of grease and oil slop.

Thanks have ordered some sae 140 classic hypoid oil non EP. That sounds like a good fit.
