Thanks Hoss. This was a 5 minute job, because you made this video for me to look at before I started it. Much appreciated.

[@YouMotorcycle]

That's awesome thanks for the kind words!

[@falconwings583]

Thanks for the video! here is one thing that I want to mention to you... if you have a lot of build ups on the magnet of that bolt, that means either clutch is not working well or your gear shifting is harsh. The gears shouldn't work rough to have the particles in the oil. Thanks again for the great video!

[@YouMotorcycle]

Thanks Falcon Wings!

[@jobbymctuned6584]

Yes, good tutorial. Folks- examine the fill plug before opening the drain plug. Crack it open first actually. Could dribble a bit so be ready for that minor inconvenience. 'Cause a frozen fill plug + empty final drive = conveniently no riding until fixed.

[@YouMotorcycle]

Could you please do a video on changing the drum brake and changing the sparkplugs on the m50

[@YouMotorcycle]

I don't currently have an M50, sorry. These videos were all working on customers bikes so I just did whatever the customer hired me to do.

[@typicaledc]

I appreciate your videos. I rode a lot of sport bikes back in the day but after about 10 years of not riding I bought an '06 M50 to get back into it and I've been using your videos to do my work. Do you happen to know the washer size or part number that's on the filler cap? Since the bike is new to me I'm going to go ahead and replace it as I change out the final gear oil. Thanks!

[@YouMotorcycle]

Welcome back to motorcycling! Glad my videos are helping! OEM Part Number for the washer: 09168-08016 Part: GASKET (8.2X14X1) I wouldn't worry about the filler cap's seal unless it looks in bad shape.

[@StanWilhite]

A good tip is to make sure you can get the "fill" plug out before draining the oil....at least that way if you can't get the "fill" plug out you won't have a bike with no shaft oil in it!

[@YouMotorcycle]

Definitely right. I show that on all my newer videos but totally missed it in this one.

[@fernandodias2023]

Nice job. Another video rhat would be very helpful would be drive shaft spline lubrication. It is a critical service that should be done periodically. If neglected, the spines will wear down to nothing especially in the rear of the shaft.

[@YouMotorcycle]

Thanks!

[@madblunted]

on any differential, you want to make sure your fill plug can be removed first.

[@YouMotorcycle]

100% right. On other diff videos I remembered to mention to do that first but apparently not on this one three years ago. Oops!

[@lifewithabe312]

You should do a coolant change on this bike

[@YouMotorcycle]

It's my customer's bike so I won't see it again for a while. At this point it's the only fluid in the bike I haven't replaced for him yet so he's probably due so I will ask

[@Mike-xf1vy]

Thanks, but ALWAYS remove the fill bolt first. If that ever snapped you're going to be out your bike for awhile.

[@YouMotorcycle]

You're 100% right.

[@dblake8756]

Quick question. According to the repair manual, you drain it on the kickstand (so it’s leaning) then you fill it with the bike in the upright position (so it fills up all the way). Is this correct? By the way, appreciate the video. Thanks for making it.

[@YouMotorcycle]

I'll take a look but that sounds right to me. You also measure oil fill level with the bike upright / not leaning. Might need a friend to help you :)

[@jo-annemurray5923]

Hi YouMotorcycle! I read you should change the Shaft Drive Gear Oil every 6,000 miles. Do you agree? I trust you more than google search. ;) thanks so much!

[@YouMotorcycle]

Hey Jo-Anne, your owner's manual should have a section called "ROUTINE MAINTENANCE" or "PERIODIC MAINTENANCE" (can't remember, it varies by bike), which will have a table showing you when everything should be done. It's a good idea to familiarize yourself with that table to avoid problems down the road by being proactive and on top of maintenance. From what I remember it's every 12,000 km (7,500 miles) or at least every two years, whichever comes first. Check the manual to be sure!

[@jo-annemurray5923]

@@YouMotorcycle thanks, I bought my 2015 Suzuki Boulevard used it was well maintained, but it didn't come with the manual and I don't know how old the battery is. One thing is for sure, I need to buy a manual. Thanks again for the great tips and advice!

What size crush washer is needed for the drain plug (bottom one). I am assuming it needs to be replaced with every gear oil change. Thnx.

[@YouMotorcycle]

Hey there. I don't know what size exactly, but I know the Suzuki part number is 09168-14004 and the price is about a dollar. The service manual doesn't actually say anything about replacing it, so I would take a good look at it, see what kind of shape it's in, and decide accordingly. The cost is only about a dollar online.

Hi, would appreciate yr comment, I am riding Suzuki M50, I just change the gear oil last yr july. Today I went for an oil change from a bikeshop, to my horror, the gear oil was LIGHT BROWN like coffee . Do you have any idea? Is there any danger or damage for my bike? I notice there are leak at side of the shaft hub. The bike shop guy told me its likely to be broken oil seal. I am from singapore, No one rides a boulevard here and thus I cant find any parts. Hope you could provide some advise. thanks

[@YouMotorcycle]

Did you see the color of the oil coming out of this one? Find the nearest Suzuki dealer, even if you have to find one from another country, and order the seal from them.

[@dean7968]

I have a 2004 volousia suzuki and see leak that seems to be coming out from where the cover goes over the brakes. Wondering where the oil is coming from considering there are only brake shoes in there.

The drain plug and fill plug are not leaking for the gear oil so unsure of where it's coming from

Now I twist throttle and engine doesn't respond the same.... Thanks in advance c50 06 Blvd 5k miles

[@YouMotorcycle]

Hey Jason, did you do your change with the bike on the side stand, or totally upright?

[@rayl7718]

After I changed the oil, I realized that I didn't put a washer with the drain plug. I dont think I saw one when I unscrewed it. Maybe it fell in the oil pan when it was draining. But I replaced it without a washer.. is this going to be a problem?

[@YouMotorcycle]

It might cause some leakage, and you might risk overtightening the drain bolt which could cause damage because you're screwing it in an extra few mm more than it's designed to go in. If you want to order up the part number it's 09168-14004 from Suzuki. The cost is about $1. For that price, I would just order it and put it in.

[@robideals685]

Is this the oil that goes to the driveshaft or is that located elsewhere? I have heard the driveshaft is known to fail on them as the factory failed to lube them properly.

[@YouMotorcycle]

No. This is routine maintenance that should be done every two years, or sooner, no matter. What you're talking about are the splines. If you google "Suzuki Boulevard m50 splines" you'll find what your after, but what you see in this video you should do routinely

[@timhassan9451]

Does the bike have to be upright or on a kick stand?

[@YouMotorcycle]

From the instructions (link in the description): All work should be done on a warm motorcycle that is perfectly upright. Not a cold bike. Not a hot bike. Not a bike on it’s side stand. A warm bike that is upright. If the bike isn't straight up, you won't be able to get enough fluid in there. Not having enough fluid can lead to problems down the road.

[@dalepoulette]

How often should you change that oil?

[@YouMotorcycle]

I can guarantee the link in the description has your answer!

[@hoisinga]

Always loosen FILL PLUG FIRST!

[@YouMotorcycle]

Yes. I've come to the realization that Suzuki service manuals aren't very good.. because you're right, you should do that, but it isn't mentioned in the manual lol

[@lifewithabe312]

Can I drain the oil without having to ride the bike before hand to warm up the oil?

[@YouMotorcycle]

Sure, but you won't get as much out and it'll take you longer. If you don't want to ride it (why not?) you can just leave it idling for a few minutes.

@@lifewithabe312 Sorry I thought you were commenting to my engine oil video. Yes I would take it out for a ride. Even just 5 minutes should be more than enough. Takes this from a 5 minute job to a 10 minute job.

[@xIKeroppi]

I’m guessing this is the same with the intruder ?

[@YouMotorcycle]

To be honest I'm not 100% sure. I'm assuming it's all the same with the only possible exception being the oil capacity. There may be a sticker somewhere on there letting you know how much to put in, if not I would look it up in the owner's manual. If you don't have one you can download them online for free or just put a call to your local Suzuki dealer and they'll email it to you or just look it up for you.
