Can you send a link I don't really do Amazon but can and would give me pictures of the engine I'm looking for
Theas are all valid?'s ..Are you gonna do some port job on the head?
Experimenting with filling intake with jb weld? To gain velocity?
Or make it bigger and maybe lose velocity?
It’s a fun subject and without testing or a lot of knowledge and experience who knows what works
Welding and grinding camshaft is an interesting idea, might need to grind those things on the piston so it won’t hit the valves if increasing lift
Keep it up and experiment and share everything
Sounds great, it’s about time people try to make gains on those small 4 stroke engines. And not only put on an oversized exhaust and the biggest carburetor they can find.Theas are all valid?'s ..
The statement was made b4 I noticed the mini 4 stroke seams to more tuchy than 2 stoke ...of the same size .. also b4 I have laid eyes on some of the parts you have mentioned above ....
As for port the head will probably just small with shaping and smooth out air flow with taking out as little metal as possible ...after looking at the intake it will be a custom made intake ! I will try my best to include details on what The amateur and runner length And material used and why .I'll give you a hint it has to tune the velocity and volume of air into the engine during a period of the RPM rang .....
As same will be said for the Exhaust
On the cam or any other valve timing I will be sure to check Is valve clearances with the piston if needed I will notch the< [eyebrows] = Valve relief> in the piston and if if increasing lift I'll also check on how much the valves springs can handle and modifications are needed....
Thanks for showing interest ! With your request I will try Keep numbers with in better and give reason why and the actual results....
yea this was just going to be a ah that will do project and go 2 stroke but I joined this place to witness new 2 stroke pocket bikes dying just like MX bikes ....... so it's time to start working on improving them it's what the future generations are going to have to work with..Sounds great, it’s about time people try to make gains on those small 4 stroke engines.

I’ve been porting twostrokes I used to never touch the 4 stroke engines.
But now I had a lot of small 4 strokes that I’ve been fixing and then selling.
So naturally I’ve been like a sponge about 4 stroke porting and trying to get as much knowledge as possible.
I have a few heads with bent valves. So I’ve ordered new valves, and I’ll do some porting.
Mostly blending for now, I’m also interested in filling the intake with jb weld in the right spots, I’ve heard that on some small 4 stroke engines the intake volume are too big and they benefit from making it smaller and not bigger as most seem to do.
Without a flow bench and knowledge for the different data you get from that, then trial and error will be my only bet.
Not sure if I have 3 heads unfortunately, cause it would be fun to see the difference if
one is only blended and casting errors is removed,
one with blending,removing casting errors and making intake volume smaller
and last head with blending, casting errors and making intake volume bigger
Then test them all and see which performs best
