Hey folks! This weekend I changed the oil and primary on my 1998 Buell S1 White Lightning. The Primary went fine, but for the engine oil there is a reservoir under the seat with a drain hose, so I drained that and removed the oil filter. After refilling and running the bike the new oil looked pretty crappy - I'm thinking it's due to mixing with the old oil still inside the engine. I COULD NOT find any low drain plug. Anyone else have this issue? Is it only possible to do an 80% oil change? Thanks for any help! -Greg | ||

I would let the bike sit for a bit after changing the oil and running it, then check the oil with a clean probe of some type. Let the oil drip onto a clean surface. You may be looking at oil that is mostly foam. The scavenge side of the oil pump has a higher volume than the feed side, so it sucks a fair amount of air. Hope this helps, Dave | ||

Being a dry sump design no oil really sits in the engine. What i do is approx every 3rd oil change i drop my oil pump down to inspect the oil pump drive gear with a mirror and flashlight. Then i spin the oil pump by hand to manually pump ALL the old oil that sits in the bottom of the tank and the oil pump feed line. It wont be much maybe 3 or 4 oz. Then i'll pour in a few oz's of cheap thin 5W30 and pump it through again just to flush the line out. I just did this last month when i changed the oil on my S3T. When you start it up the lifters will usually clatter for a while until they re-prime themselves. It would be overkill to perform this ritual every oil change for sure. That's why i do it every few years when i inspect the oil pump drive gear. Don't forget to pick up a new gasket for the oil pump! | ||

Make sure you use the right motorcycle for your oil. |
