I have not seen these available for the 2018 models yet. I think your money would be better spent having the stock head machined for proper squish clearances and compression.

But i dont have anyone to send the oem head to, so it is bettet for me to by a s3 or vhm head.
And the s3 head was not to expensive either. But is it better then stock head
Thats the question?

Here is another option: https://2strokeheads.com/index.php/gas-gas-performance-heads

Yea but i dont want tonsend my oem head.
I rather buy one extra so i can ride.

There is the billet option as well

The S3 head is nothing more than a fancy stock head with a tighter squish band. They’re really not worth the money. Plus they aren’t available for the 18 yet. Spend an extra $100 and get an RK Tek billet head. It’s worth every penny

I really don't like the look of the ridges in the RK Tech heads. They go against everything I've ever understood about 2T cylinder heads. I would really like to know how that supposedly works better than a smooth chamber.

Supposedly, channels the air/fuel mixture towards the spark plug.
The tapered channels has a venture effect, which increases the mixture velocity towards the spark plug.

Google "Singh grooves".

Thank you! I'll read up on it.

There is a s3 head for gg 300 -18/19
The RK tech head with Taxes and shipping to Europe is quiet expensive. To much for my taste,,,,,

Save yourself some money and take your head to a local machine shop and have them mill .6mm off the squish band. Now you have a $50 S3 because that’s the only difference in an S3 and stock. The chamber is the same

I just got off the phone with a friend of mine that was a top NHRA SST driver/engine builder with five national championships He said absolutely that should work, increasing turbulence and wavefront focusing is very real.

Here's pretty much what he said as far as doing it on the Chrysler Hemis he built which have a very similar combustion head design.

Quench, swirl and tumble are definitely real. That is why you try to keep the quench area very small as it promotes more combustion chamber turbulence and the small amount in the quench area really never burns in time anyway. With steel rods, you need .035 piston to head clearance, and you try to keep it there, and no more. Alum rods are .045.

Oh, I understand quench. It was the ridges I don't like the look of. Just seems it could make it easier for detonation. However, I have been reading and it appears it works so, I guess it's all good.

BTW, off topic, do you go by that handle on some Mopar forums? As a moderator perhaps?

The head is much safer than the stock head AND, best part (besides the huge performance increase) it comes with a money back guarantee!!

Does S3 offer a money back guarantee??


So, there is no risk.. only reward LOL..
