Anyone else come across this problem area? The new rod is on the left side in the photos.

That rod reflects 2 changes that were done to the FA180 rods I have purchased in recent times. The slot cut into the bottom was employed in a rod I purchased in the last last year or so. The groove cut into the crank web face was added to a rod that I purchased just a few months ago. The OEM FA180 rod from an engine I purchased back in '98 when they 1st came out was made like the one that failed in your friend's FA125.

The FA450R3 master rod I recently purchased also had the web face groove treatment while the one it replaced did not.

I suspect that Saito has done this to most of their engines to improve crank journal lubrication.

It will work in your FA125 & will probably eliminate the problems your club member experienced.

Just installed a Keleo exhaust on my 125. Having a problem with leaking exhaust oils at the bolt. Nothing between the head and the muffler. Do any of you think a sealant will work to stop the leaking. Any other suggestions. Richie

One of my 82s had been run for about 40-50 hrs and there was only a little carbon build up on the exhaust valve . Elsewhere it just wiped off . The dreaded carbon , castor combo is not worth worrying about me thinks . Cheers the pope

If I recall correctly (where I got this one - a friend or an old engine) the instructions say to use clean oil on the threads when installing and that actually seems to help. Take what you have off, clean it up, lube the bolt threads (both of them), reinstall and test.

I tried to keep it "civil" but my posts were constantly being misquoted & taken out of context.

I'm not familiar W/any "bolt" holding a muffler onto any Saito single. I'm curious now.

So the question still remains. How do you "bolt" a muffler to a Saito FA125 single?

Perhaps he is speaking where the engine bolt's go through the flange that secures the exhaust pipe and engine to mount

This is how I do it.

Seriously, it's time to stop trying to pick a fight. You know what he meant. We all know what was meant. I once joked that it was time to go kick the wife and kiss the dog to a guy who was fighting with someone here on RCU. One person was so offended he wanted to press charges against me. True story.

The "bolt" passes through the muffler and into the cylinder. As it turns out, I did not have the "bolt" torqued enough and it leaked. Problem solved.

Here we go again, I ask a perfectly legitimate question & I'm "picking a fight".

The muffler in question as 2 bolts as I read the posts.

If he knew what he meant, he wouldn't have asked the question. By the way, I didn't know what he meant either. I've never seen that setup.

Is that an assumption on your part or have you had "complaints” from others?

The fact is, now that the OP has posted a picture it seems that my question was valid as that is a set-up that is totally different than any I have seen.

It seems that perhaps an apology is in order?

I have never seen a site where there seems to be such a childish propensity to take offense when something is questioned or debated.

That's great. It seems that Keleo mufflers cause trouble in this forum.
