Normal to have fine bits of metal in oil filter?

[Blagger]

p.s what's the deal with these magnetic sump plugs? They sound good!


Here's a link to some pics of some for sale

They're a pretty common item, a few searches should get you there

Oil is cheap, motors arent. There is heap of info on the web about why 5hrs is a good time to be changing the oil on a 4stroke.

Lets say I see brass fillings in my oil, you'd be running another 10hrs or untill it shit the bottom end. Bit of a gamble. Up to you I guess but thats what majority of the guys that own 4strokes do that I know.


Actually just reading again, CRF would be different as they run seperate trans and engine oil, RMZ's don't.

I still change mine every 5hrs and its a honda and like many have said there is always very fine "stripper glitter" in it

I do an oil and filter change every 5 hours. The filter is overkill, but it's not going to harm the engine and I can afford it.

The Kato comes with a magnetic sump plug, there's always glitter on mine as well. Last oil change was after a particularly clutch-abusing ride at Woodhill and it was covered in crap, oil was very cloudy too. It's normal.

bought a low km DR 650 off the internet. Sounded a bit rattly so immediately changed the oil. Ferrous and non-ferrous sludge in the oil. Thought "oh dear, caveat emptor, I'm f*#@& now"! Ran it for a bit, drained it and no foreign substances this time. No problems since despite motard and trail work. I suspect the guy who got it new never did ANY oil changes.

Bike still wasn't starting well so got the valve clearances checked, they were all over the place and after digging deeper turns out there was heaps of wear under the cam shaft and the top end is now screwed, bike was most likely run without oil prior to me owning it! So beware if you find metal filings in your oil, they didn't even look like anything too alarming...

checked you valve clearances?

You tube it, it's pretty simple to check.

[White trash]

No offense intended, but christ there's a lot of crap being spouted in this thread.

Listen to Noobi.

Dang your right there best watch out there another truck load on the way im sure. My 450 as with countless others have always had small traces of fleck in the oil you only have to see how they get ridden to guess how along with clutch abuse/wear these thing are not road bikes pot around (you'll notice all comments that are telling you the motor is poked are from the road section )

Nah not aimed at you. Agreed that people are trying to help, but bad advice is far worse than no advice...

Thoroughly suckfull situation, but I guess the "no nothing" road riders nailed it first time round.

Got a quote for the suggestion that the motor may have been oil starved and the cam would wear the journal?

No, but the people that suggested it could be a worry were dismissed as "bad advisors" and there's nothing to worry about. Just found it ironic is all.

[browny]

its usual for my bike to have a bit of glitter at an oil change so i wouldnt have been worried either,not usual for bike to get run with no oil in it tho.i guess thats the down side of buying a new bike and not knowing its history.

[Jay GTI]

Well as:

a) it is perfectly normal to have glitter on the sump plug

and:

b) there has been a lot of bollocks in this thread and the fact there are issues with the bike doesn't make the advice any less bollocks

I fail to see the irony. I do however see someone with a bit of bad luck...

Agreed with others,99% of the advise here was all gravy no need for comments like this i say we were all only trying to help just because we wernt bang on with our diagnosis doesnt make us all unhelpfull and potentially damaging.

[crfchick]

I really appreciate all the help and ideas you guys have suggested. I was more aware of potential problems and otherwise may not have put the bike into the shop to get it checked out if it hadn't been for all your opinions.
Just wanted others to beware that even some "stripper glitter" could indicate bad things!

The bike must have been run a long time with no oil, A mate forgot to put oil back in his CRF250 and it ran for 30 min before he noticed power loss. Cam and rocker had worn.

He was told to replace the oil pump just in case so that may be a good idea.

[crfchick]

Thanks for that info CRF119. Sounds like what's happened to my bike too - cam is worn and the housing the cam shafts sit in is burred (hence the aluminium in the oil). My concern is when or what casued the bike to be run without oil, it must have occured before I bought the bike, but if the oil filter wasn't sitting in the right place because the spring was missing, would this also have caused a blockage to the engine?
Other concern is how far the damage may have spread, I'd hate to get it all fixed up to have the same problem occur!

Having no spring would cause the oil no to be filtered. The oil could cause a blockage to the top end but unlikely.

My friend drained his oil fitted the sump plug and then got side tracked and never thought about it till the bike slowed and i inspected it.Result was no oil at all. Maybe the same happened to your bike but in steed of fixing it they just filled it with oil and sold it. Id like to think not because it cost my mate 2.5g to fix his.

Probably worth a full strip, clean and inspect.
