There was a topic on them just recently.  Contact Tom L. He seems to have a good set up for them.

The GX200 is what the 196cc Clone is based on. Parts are interchangable. What are you looking to do with it?

I would not even waste time with a true Honda motor,they are very pricey and you have to rip everything out anyway. look for a box stock project motor,or kit on the karting web sites. I would go with a bsp 2 cam,max stroke crank, stock piston, the stock rod will be fine for now,billet aluminum flywheel, .615 over bore carb, some 10.8 springs,an air filter adaptor and a fuel pump. the carbs on these will take a fuel pump without changing the seat in the carb. that would get you up in the running as of now. this is what all the mini pros built now run. most kart shops have all this stuff as a builders prepaired motor kit for around $300.00 or so.good luck and have fun!!

If you are boring it .615 are you putting a sleeve in it to bore it that much? .525 is 5/8 ,how many ccs do you gain?

The .615 is the venturi size in the carb.
Cylinder bore is restricted to no more than .030 overbore.
Its actually cheaper to buy a new block than have one bored.
MiniPro rules are written to help keep costs down.
What can be done and what we allow are two different things.
The plan is to get people into racing not drive them away.

Tom
 make the 212 legal
my 5 yr old has one of these.. if the 212 was legal id have to whip it out   196cc clone .030 over is a what? what does the max stroke crank give you? seems nitpickish

i thought we went over this on facebook.......rules say 196cc clone or honda gx200. the over bore rule is getting changed this year. i belive its going to a stock bore size rule. a new block is 30 bucks.....why mess with getting it bored at that price! you will never notice a power defferance with a 30 over bore anyway.a max stroke crank give you a better "in the hole" mesurement,which doesn't change the cc's.
Title: Re: gx 200
Post by: TomL on December 01, 2013, 08:37:08 am
Yes the rule is 196cc. Using either the "clone" or the GX200 Honda. The Clone is a copy of the Honda hence the term "clone".

The 212 is not quite the same, close but there are differences.

A major difference is the size (cc). a 212 is a little more than 8% larger than the 196. That's a lot.

We are changing the bore rule to NO over bore. This will help keep costs down. Like Russ stated buy a new block for 30 bucks.

All mods allowed are bolt on, no machining except carb (must appear stock) and porting (just cleaning up the intake on the short side radius is enough).

That's it. We don't need we don't need another money spending class. Buying everything new should get you into MiniPro for a thousand bucks or less. You can buy a race ready motor for less than a flywheel for a typical mower build.
