they are all the same crap from china unless its $350 and says something like "comet, blah blah indiana" stamped to the bell of the drive and cam of the driven.

My ebay strategy: sort: price+shipping lowest->highest

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 ???

 

[ultralight01]

Stage 3 mods!!!!

Stage 6 mods work better.............. Just sayin of course !

P.S. And if you pull the governor your gonna want a rod its cast. It looks to be weak link when i tore mine down. I will find out for sure here in a few weeks. lol

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.

This thing is pretty heavy to carry up a flight of stairs. Wish I could of picked up an electric start for 199.00 though.

Me too!

 

[Jrgunn5150]

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

 

[chancer]

Originally the non electric start Bob found at 169! then FR found the electric for 189!

 

[Jfive]

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".

 

[chancer]

That's a good deal.
Looks like we may GAB this thread before Bob gets to it!

 

[Jrgunn5150]

Everyone will do eveything before I even put gas in mine lol.

 

[chancer]

Then you can use them all for guinea pigs! See what to GAB and what not to GAB.

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.

Joe Rep'n the 405 found it! Got to give credit. I was on the Home Depot Lifan for $250ish

 

[chancer]

Ok now it is GAB!!!

Oh and I thought all this new 420 nonsense was your fault!

 

[Jfive]

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.
