You know................

It would cost Suzuki the grand total of about 25 cents extra per bike to include a magnetic oil plug as OEM.
And, it would be great PR.

SUZUKI..........ARE YOU LISTENING?

My rear drain plug has a magnetic core in it...

Thanks.

The new plug is an automobile oil plug with a rubber fabric type washer. Would it be better to use the Suzuki washer or the new washer that came with the plug. I did order the Suzuki plug as a backup plan. I just didn't want to wait 5 days.

I know this is a simple question I just didn't want to leave all my oil on the road if the shorter plug vibrated out or something. I couldn't figure out why Suzuki used such a long oil drain plug. You would think they had a good reason....
The length and magnetic qualities of the drain plug are useful to attract the tiny metal particles that get sheared off from all the moving parts. The rubber fabric washer should be fine, because the washer is really there so you won't overtighten the bolt and thereby crack the case. The washer doesn't prevent a leak, as evidenced by the fact that most of the people on this site have posted testimonials that they don't even use it, and it doesn't leak their bikes.

Suzuki never listens. I don't get the "crack the case" stuff, wouldn't you have to torque down the drain plug really hard to do that? How many VL800/C50 crank cases have you seen cracked in this manner? Seems absurd to me. The VL800 oil drain bolt is in the right side half of the crankcase and I would think you would strip threads before you crack that aluminum.

That washer is there for two reasons:

1. It is sacrificial material so that the sealing surface of the block is not damaged by rotating friction when the plug is tightened and

2. It is a sealing material that is compressed when the plug is tightened to the correct torque

It is the correct torque that holds the plug tight and prevents the threads in the transmission housing from being stripped.

On the boulevard and VL 800, that torque on the drain plug will be a maximum of 15 foot-pounds.



Installing a shorter drain plug then stock will allow great case debris to accumulate in the threads above the end of the plug. That Accumulated debris will cause damage to the threads when a stock drain plug is reinstalled if the debris is not flushed out.

The length of the stock plug is designed to keep the debris out of the threads before the oil is drained.
