A piston kit generally includes a piston, rings, wrist pin and a top rod bearing.

I haven't seen any for an LS650. 94mm or over size. Do you know of a source?

Stock pistons are only available from your local or online Suzuki Parts dealer. It appears the 94mm piston and 94mm rings are purchased separately.....and they are only a set if you buy the oversize 94.5mm piston set. (The wrist pin and clips are also purchased individually).

That's the only source I know of as well.

Most motorcycle problems are caused by the nut between the seat and the handlebars. Make sure yours isn't too tight or too loose.

We have a 94mm Forged piston that includes rings and wrist pin.
It is a Wiseco with a slightly raised crown which produces 10.5:1 compression ratio. It does add a nice little punch. 😎
Just $199

It cost a few dollars more than a stock piston but it is much stronger, being Forged.

Besides, they are downright beautiful to look at.

Just got off the phone with the machine shop...

Stand by... this is some serious stuff going on here.. Just.. what can you say when you get that kind of news??? Undecided

I mean.. you think you are doing OK.. It looked pretty good to me when I took it off.. ya know?

Well.. total taper (out of perfect) is .. less than .. .002 inches. Shocked

No bore needed. No cleanup needed. They honed it, and I am good to go with the existing piston, which they checked and cleaned up as well.
All I need to buy is a ring set!

The valves had a weeeee bit of carbon on them though.

This is an incredible testimony to what can be achieved when you use good oil, change it regularly, keep you idle speed up, and don't abuse your bike.

Youzguyz....I looked for your post on the Suzuki Facebook page. I couldn't find it. I was going to post a comment of support. How long ago did you post on that site?

Amazing that there's so little wear, too. So, since I have a 2015 S40 and I'm 59, if I take care of it as you have yours, I could still be riding it (or at least LOOKING at it) when I'm ready for the Old Soldiers' Home...?

It is indeed amazing. Comparing youzguyz' 155kmiles with the minimal work other guys manage before destroying the engine really illustrates how neglecting the machine can ruin it. Maybe Youzguyz got one accidentally built from all primo parts but still it's a brilliant result, especially the bore wear news. Wow!
On the similar topic, I have a Holden Commodore wagon with the old Buick 3.8 litre V6. Just pulled the heads off last week to replace a burnt valve (first time the engine's been opened since built in 1992) and found zero lip on the bores and the factory honing marks are still visible. Just a quick lap of valves for run, new ex valve and back to work. 280,000 miles. Doesn't sound as impressive as 450,000km but most of these donks are ready for scrap or rebuild over here by 250,000km. This one gets the regular maint. too.

Hey, Gizzo,

I had a 1991Oldsmobile Delta88 with the 3.8L V6. At 265,000 miles, it still didn't use any oil, got mid-to-high 20's mpg...only engine malfunction was the cam position magnet breaking out of plastic cam gear holder (replaced timing chain & gears while I was there).

I'd still be driving it if some yahoo hadn't run off the road, pushing the Olds thru my garage. *sigh*
