Don't say it ... *sticks fingers in ears* !! ... But yeah, it's true!

I was wondering: my 2010 570 has probably always had the ignition map set to aggressive w/ a switch. Something to think about? Maybe stock is stock for a reason

I've put an hour or so on the bike since the last oil change when I found the swarf / particles. Going to have a look at the oil screen. Are there any signs that it'd be useful to watch for or things you're curious about, in case I have an engine that is *about to go*? In other words, where should I look for evidence that is useful to analyse the trend?

If the coating on the big end is flaking, then how is it diagnosed for sure? Does the crank have to be pressed apart or can it be measured through tolerances or seen "from the outside" somehow?

These are the steps as I see them:
Step 1: Check the oil screen. If particles, then wash, examine closely, take pictures and post.
Step 2: Remove an engine cover or two and poke around - what to poke at? Can I at this step tell anything conclusive about the big end?
Step 3: Split cases, have a closer look?
Step 4: Press apart crankshaft, inspect and document.

(I don't have tools to split the cases but could probably borrow, and Step 4 I'd need to get done at a shop - so those steps aren't likely to yield useful information very soon - broke atm - therefore I'm thinking to make the most of step 1 and 2.)

Check your Step1,smal tiny metal spikes seems to be normal but if there is metalsludge you´re doomed,specially if the sludge contains chromed pieces.I also cut up my oilfiltres to check for chromeflakes.Chrome flakes/sludge is as sign of a broken bearing.

I could feel the gap in the conrod by hand,but you have to remove head and cylinder.Removing Engine and taking off head+cylinder takes about 3beers a normal weekday

Btw.....

congratulations!!


- and thanks for the info!!

There was indeed some sludge last time :/ ... Or yeah, with my limited experience I'd call it sludge ...



a few more pics here: viewtopic.php?f=5&t=18292


I took a video just now ... is that a clattering/knocking/hammering type sound I hear? Seems to be more audible from the left side. From somewhere, well, where the big end should be, or hmm actually I'd locate point a bit further forward, towards the cylinder. But hard to tell.

Does anything jump out at you?

(I loooooooove the reverb down in the basement car park here at work.)

Kris that is the death rattle, take the head and cylinder off, wind the crank over to tdc and push and pull on the rod in the plane of the cylinder. You will feel radial play. Stop riding it now and you will save piston and liner maybe.

I showed you a general selection of the tools in the first page, cylindrical rollers make splitting the cases really easy.

Jas666 that looks sweet, you will be assembling soon by the looks.

Oh well Good to know - thank you!

I'm actually looking forward to doing the work, it's only the money part that's less fun. Might sell the Suzuki, but I really really don't want to. Will probably find some junk around the house to sell. refrigerator, washing machine, who really needs that stuff anyway?

- Sorry for the threadjack!!

berglsmerg

Don't worry about the threadjack, I'm more concerned that you'll sell your refeidgerator and have no cold beer to help you fix your bike.

Just snapped this one ... I think I'll figure something out for the beer Or facilitate the repairs with judicious use of hot toddy ..!



I'll have great support from some local mechanics for the rebuild. I won't want for competence! I'm already ahead a warm fuzzy feeling.

Jeez mate it looks well cold enough to freeze beer ! You could sell a kidney maybe ?

tourist

Gah, a nuked bearing in my Berg and my Suzuki is sideways ...

but ... I think I've figured out the logistics of doing this.

I'm looking forward news on the 610! do keep us posted, and thanks for this thread, it's been quite useful already to gain a better oversight

berglsmerg

Thanks mate, keep the faith ? Perhaps you could bomb the ass out of the motor as well as a rebuild ? Time to show these old school, floppy crank, stink bug high rear end, wheezy conrod, 206 main, junk riders a good lesson !
