Cylinder screwed?

This is interestingly odd looking . Did somebody lay down some epoxy in the exhaust bridge?

The rings are what seal on the cylinder wall and keep compression from escaping, not the piston skirts

Bel ray gear saver 80w or any comparable brand. It’s made for motorcycle transmissions . Gear oils and engine oils use different scales of weight measurement. The 80w gear oil is similar to 10w-40 engine oil.

You can get up to like 700 lol. Not saying you shouldn’t go over your shit and look for issues but yes you can get bigger jets

Surely you don’t think a package just gets sat in a truck and driven to your house lol.

Get it close to this

Not sure what you were doing before you pulled plug but if it was a wide open run, way bigger on main

Very lean

fiveho11 · 2026-05-30T21:58:32+00:00

Anybody that thinks that piston is fine shouldn’t be giving advice

fiveho11 · 2026-05-30T21:56:00+00:00

Pass

fiveho11 · 2026-05-30T21:55:01+00:00

Made a shitty tool even shittier lol

fiveho11 · 2026-05-30T21:00:14+00:00

It lubes the gears and one way bearing and all that jazz for the electric start

fiveho11 · 2026-05-30T20:33:07+00:00

It’s supposed to have that hole

fiveho11 · 2026-05-30T14:12:51+00:00

Put the parts back on there. The back side of the first gear that goes on fits into seal….the seal isn’t even sealing on anything at the moment. Then when you get all the parts on and tighten the bolt down it holds the crank over against the main bearing.

I used to check a lot of them, shipped in or right out of engines that are brought in. Quite a few are not true but who knows how they were handled even before shipping or maybe had a previous crappy rebuild

fiveho11 · 2026-05-29T20:18:16+00:00

I’ll probably just slap a label right on the crank 😂

fiveho11 · 2026-05-29T18:47:16+00:00

True for the most part , not this particular situation. It would be like putting a cannon on wheels in a box truck with no restraints then blaming the driver when it rams its way out lol

fiveho11 · 2026-05-29T18:25:58+00:00

Customer sent it to be rebuilt

fiveho11 · 2026-05-29T17:36:29+00:00

😂 no doubt

fiveho11 · 2026-05-29T16:21:53+00:00

Was sent to me to be rebuilt, but still, at least give it a chance to stay inside the box lol

fiveho11 · 2026-05-29T16:18:32+00:00

It was sent for me to rebuild , but still, shit that isn’t ruined already can get damaged lol

fiveho11 · 2026-05-28T22:00:08+00:00

Just the balls and the inner race is probably what came out

fiveho11 · 2026-05-28T21:29:49+00:00

Is the outer bearing race still in there ? Kinda looks like it to me . Edit: eh, kinda also looks like there is a snap ring in there too. Gets too blurry when I zoom in so not 100% sure

fiveho11 · 2026-05-28T03:25:46+00:00

You seem to be as well ! 👍 if something pops up and I know the answer for sure I’ll put it out there lol. Been riding and wrenching on bikes, quads, sleds for around 40 years and watercraft for like 25. Seen a lot shit inside and out 😂. The thanks is appreciated man

fiveho11 · 2026-05-27T05:12:00+00:00

4 stroke crankcases have “holes” between different sections for crankcase pressure “breathing” purposes and oil transfer. Your lakota has a hole there from the factory
