Zeda80 engine build.(obtaining parts and game plan) (69.4cc)

My motor is finally purchased...i went with the pre sale option at $109 ,delivery im not sure when will take place..This will be somewhat of a slow build as im only expecting to invest so much per month towards the build and im in no hurry anyways..lol

You can find this particular motor and alot more sold through
ZedaMotorsports.com

Expect lots of before and after pics of the build.

Ill start with bottom end and show more as it happens.

So, heres the game plan for the bottom end build...To start, the motor will be taken apart and inspected prior to the changes and thoroughly cleaned.

(Bottom end)
1. Balanced crank (Zeda factory)
2. Lightened rod and pin
4 RB Tech 6202 2RS C3 (ABEC 3) premium crank and clutch bearings.
4. Upgrade upper rod bearing.
5. Seal retainer. (comes with motor)
6. Arrow (Red) metallic clutch pads

Ive always read 10x14x13 was the stock sized bearing and 10x14x15 was the "upgrade" size wise.

That's what I thought too until I received the 50cc scooter bearing and compared it to my stock bearing. So now idk. I'll take your word for it anyway as I'm sure you'll measure everything and let us know when you receive your new bearing.

When i was trying to find bearing sizes ,all info i could find pointed to 10x14x13....if you scooter bearing is 15 then its the size im being recommended to upgrade to...im fairly certain of the size.

Same here, I thought those dimensions were correct, and that's what i ordered, but then it arrived in the post and was clearly shorter than the stock. Stock looks like 15mm but I can't check that now.
I think the common 50cc scooter size is what you ordered. It's quite possibly the same bearing as mine in every respect except for the silver plating.

This scooter bearing cage seems like it has less stress risers than the stock bearing cage...

Ha good luck with that!
From all my reading and searching I believe you want a genuine Stihl 028 (not Stihl compatible- that's the same as the stock!) bearing.
But if you can find or make a couple of reliable spacers more easily, I think there's nothing wrong with the 10x14x13mm "50cc scooter" bearings.

Ooooh! That is an interesting find! It does appear to have longer pins than stock.
I'm sure it's worthwhile having a look at one. Can't be worse than a spare stock bearing at the same price.

What is shipping cost to usa?

 

[6blueoval9]

Sigh..im lost....considering stock is supposed to 10x14x13 and if the bearing i ordered which is said to be the same if it is shorter then apparently thats not what i want to use...why would i want to go smaller if stock is already considered too small.

 

[FurryOnTheInside]

Oh, yeah shipping cost is a bit much. €3.90 for EU and €4.90 for non EU countries.

Im about ready to just leave the bearing in it and hope for the best
