I'm going to "Sound off" here a bit but first I want to remind everyone of my racing heritage. I've been involved in racing snowmobiles, mud drags and D.I.R.T. Modifieds and now lawn mowers. What I first found ironic in lawn mower racing rules was the "Must start as a certain block" and "All internal modifications are allowed". What? No other racing organization that I know of allows internal modifications without limit yet bases the start off an engine cu in. If you are going to have a cubic inch or cc limit it must remain as a complete limit. Let me give a clearer example using a small block chevy. A typical 350 without being resleaved will get to 4.060 maybe 4.090 if the casting is really good. Now a bowtie block 350 will get to 4.215 from its 4.00 stock bore. A small block 400 will get the same. But now you say the small block 400 isn't legal because it started as a 4.125 bore at the factory. Kinda nonsense if you ask me. That's why they use a cube checker to keep everyone under 368. If I want to run a 4.125 piston and 3.44 stroke it is allowed. If I want to run a 3.82 bore and a 4.00 I can. The is no physical size difference between the 44 and the 49 block. It can not be measured externally to separate the two. There is a minor casting difference that allows a trained eye to differentiate the two. This is not a big block. you can't make the Intek 49 as big as you can the 46 Kohlers with any amount of boring. The material isn't there. What I see is the pure hatred of the intek by people who shrug their shoulders at 60+ cube Kohlers.

Depending on tracks. We race a touring series which has tracks as small as 400 ft total to 700 ft with different surfaces and shapes. We utilize 1st gear for pits and race 4th - 6th. Next time I take it apart I'm going to eliminate 2 and 3 gear.

The 2 Barrels were only on the 30 hp motor both vertical and horizontal.  That intake and carb will bolt up on 18 - 27 hp commands.

That's not true, they actually have two barrel intakes on several of the new 2014/2015 model engines including a 22hp CV682 or CH682, and many other models from 22-27hp as well as the 30hp. But you are correct in that the two barrel intakes will bolt up to any of the 18-30hp engines.

hp= rpm x Torque

rpm does have a lot to do with it. 

A lot of thought has gone into this motor and it was an experiment on my part to see if I could make it work. I still have a bit to do to the valve train, ports and head and might even try to stoke it a bit more. If I can do that, the piston and pin will be a lot lighter do to a more common replacement.

Ordering the bolts and bearing soon.

Jason mikula who won fxt in the uslmra finals runs stock rods and pistons. With kawaski v twin. You have more torq cause of big parts then any other motor. So you don't have to spin it to the moon.

You buy that line I have a bridge in London for sale real cheap too!!!
