350sxf with metal in the oil

Recommended Posts

I was riding yesterday at the track and everything seemed fine till the last ride. I got on the track and the bike was making a weird noise and bucking back and forth. I pulled off thinking the rear axle might be loose. As I slowed, the clutch started to grab and pulsate. I was able to ride it around starting and stopping to try and figure out what was going on. The clutch was grabbing.

Today I drained the oil and found metal on the drain plug magnet. Little bits and pieces. After the oil drained I put the drain plug back in and pulled it out to find a little more metal bits. No metal was found on the oil filter. I poured about 500cc of oil in to flush it and drained it again. No metal this time. I then put the used oil filter back in and filled it with oil. I started it and then put it in gear to run it on the center stand. When pulling in the clutch the rear wheel would still spin. Hitting the rear brake pedal to stop the wheel with the clutch in and releasing the brake the wheel would spin.

The metal isn't clutch material. Maybe something with the clutch basket. I don't know. I guess I'll have to pull the clutch out to explore more.

All this after 30 hours on the bike.

Any ideas?

Exactly same as mine. no issues, just minor particles in the oil. just keep an eye on it, but I always get some metal in my oil.

As for the bike on the stand, I also found this strange as the wheel spins even with the clutch engaged, but on the track it's fine, so I never gave it much more thought.

My 350 has metal on the drain magnet every oil change also and the clutch does take a while to warm up.

30 hours on mine so far and the only complaint I have is a notchy gearbox and the forks. The rest is awesome.

Same here. Nice that KTM gives us a magnetic plug. Just small metal slivers.

I am not too excited about the tranny either. Some false neutrals that could have ended bad. May try to put the shifter down a notch but as you all know that may require AStar elf shoes:ride:

I've always had whiskers of metal on the drain plug but never particles like today. Since I had the problem yesterday and now more metal, it seems like there is too much material on the magnet.

I'll call my dealer tomorrow and see if my vin number shows up for any alerts/warranty issues.

Should I say what oil I'm using or will that start an oil war? Because of this, I may be changing brands.

A fellow rider/mechanic thought it was just the clutch plates sticking or the oil was too warn out. I change my oil and filter every 5 hours and I don't ride the clutch. He suggested using the oil that KTM recommends.

I'd say change your oil more often. It's not about the oil...The frequency of changes, yes. Especially being a high revving bike. And don't be fooled into believing the oil that KTM recommends is the best...It's only what they recommend. As Ville will tell you - a lot of marketing propaganda there. And yes, check your VIN...The link is on the KTM site somewhere..i just used it.

I checked with the dealer about my vin number. It's clear of any recalls.

The service tech said to check the oil screen pickup for metal. When I questioned him about this, he didn't even know if the 350sxf had one and he'd have to look it up. So, he offered something and didn't know about my model bike. Grrr!!! He suggested I look at the clutch for any damage. If there is none, then start with a topend teardown.

The question is now... Is there another filter screen?

I guess I'll be looking through the manual for such a thing.

pk6n, thanks for the info.

I've seen the filter kits but wasn't sure if our model/year applied.

rickk, you say change the oil more often.

I change the oil & filter every 5 hours.

How often do you guys change your oil/filter?

Do you change the filter every oil change?

Thanks for all the input.

its probably excessive but i tend to change the oil every two or three rides. depends on how bad i beat on the bike.

KTM dealers just received a service buliten RE the trans/clutch shaft on the 350

I'll check this with the dealer I bought my bike from (they were closed today). Maybe they can do the exploratory service. Nothing happens this week though, I'm having my suspension revalved.

03SVT, Every 2-3 rides is not excessive. That many rides is probably close to 5 hours. It's better to error on the safe side.

same story for me as well metal in every oil change, done 30hrs and I use the motorex 10w60 and change every 5 hrs, I too had shifting issues but since I replaced it with a hammerhead shifter for my size 11 boots its gotten better.

I called my dealer where I bought my bike and talked to the service person today. I asked him about the service bulletin and he confirmed KTM had sent one. I told him I thought I had that problem but what are the signs. His reply was, "you'd have metal on the drain plug magnet". I replied "I do and I have pictures". His next comment with a concerned voice was "really". He's contacting KTM about the issue and I sent the pictures to him.

I'll wait and see what happens in the next couple of days. This dealer I'm going to work with is very reliable in the area.

Keep us in the loop on this.

I think all of us have had metal on the drain bolt though so I'm not convinced there's any issue, but I open to hearing what you find out as perhaps there actually is a problem.

Does anyone have this service bulletin?

Before everyone panics. as new gears wear in tiny slivers come off the faces of the gear teeth, they are dark grey, maybe 8 to 10mm long and maybe 1/4mm or less in diameter, being steel they stick to the magnet, this is normal on any new bike and to a lesser degree any bike.

That said the bulletin titled I saw is titled "PB1103". Not that familure with bulletins from KTM but as I read it I think the PB means "Parts Bulletin" as opposed to a "Service Bulletin".

It is 3 pages;

Page 1. It applies to engines with case #12 0001 to 12 0470 and talks about a different seal on the left end of the transmission main shaft behind the slave cylinder, this seal has changed and that moves the bearing over .2mm and that requires a different shim washer between the bearing and 2nd gear. What it leaves unclear is, is this action that should be taken on all bikes? Or is this something to be aware of when replacing parts? Having re read that it’s a “Parts Bulletin” I am suspecting it’s a non issue unless your replacing the bearing?

Page 2 explains that if you buy new cases it comes with the new bearing & shim

Page 3: Talks about a change in the size of an oil jet in the oil circuit that lubes the clutch, if the seal covered on page 1 is changed then more oil goes into the clutch which makes the clutch drag which you can fix if you change this jet from a 100 to a 60.

Sorry if I set off alarms.

Dave,

Thanks for the information.

My shop mechanic mentioned about the shim. Having the cases split so early (30 hours) isn't something I wanted to do. The question I have is...Are "parts bulletins" covered under warranty for parts and labor?

My mechanic contacted KTM. I have to authorize the tear down for him to do the work. Once he verifies the problem/damage KTM will then be notified and hopefully cover the cost. I drop it off Tuesday and should know something that day. I'll keep you posted.
