Step 1: take possession of one engine, not broken.
Step 2: begin fixing said engine, not broken.
Step 3: stare at one now broken engine.

I think I'm going to get the 212 running properly, then move it to the minibike.
I'll put ONLY one engine on the buggy, but it will be the 420.

Minus the governor/oil sensor this will be broken in on the buggy free of GAB. Then stage 1 mods. AND then ???

My opinion, FWIW, I would go ahead and do the stage one stuff and run it.

And you know, I thought there was another box in that box, but there isn't, it's just the engine lol.

I'm pretty sure mine was less than 199, I'll have to go through my purchase history, I thought it was 189 though.

They where 199.00 then they where gone after that. All there is now is recoil start. Maybe next run of engines will be the same price but maybe not. So I picked one up for 164.99 "make offer".

Added the stock specs to the fist post.
(All hearsay, I haven't opened it yet)

390/420 Connecting Rods seem to run from 4.410" - 4.450" and I saw one at 4.610"..
I think the stock 420cc Rod is 4.430".
Guessed the Piston sits around 0.035" In the Hole.
The cam stuff came from that Geoff at Vegas Carts.

Being somewhat new here wtf does GAB stand for? Are you using as chit chat. Or some other meaning.

Also kinda low compression compared to other new engines. Easy starting since a few of us got recoil starts.
