I recently reshaped the combustion chamber in my 79cc predator and the amount of torque easily doubled. Next part I'm going to reshape will be the cam shaft. The goal is to atleast triple the power output of my scooter engine or blow it up trying. Good to see I'm not the only one going extreme thanks for the vid.
Ill be buying a head from you soon. Just gotta get past spending the coin on a good race head for a weekend toy lol. I currently have a Pred 212 with 32deg flywheel, .265 cam, billet rod. Light porting i did my self, 26mm carb tuned. Runs great but i really feel a bump in compression and bigger valves to go with that carb would make all the difference. Im almost convinced. Great work man
I’ll be here ! Thanjs
Damn that looks good! Sweet stickers too. Pumped about you getting your own website that will be sick man.
SAL Motorsports ya can’t wait for website too
Yea .. it’s going to be the #1 site for high performance predator / clone builds .. big and small block .. from my heads / my cams to custom Paul’s karts valve train , working with manufacturers to revolutionize the industry with better parts .. like 32/28 seats that don’t touch ! Custom valves , and I just bought a CNC mill .. anyone want to see Paul’s karts rods ? Side covers ? Valve covers ! Imagine how cool these engines will be ! Just wait ! Next year or so will be the future of karting and mini bike power and customization ... thanks for the support , the like , and the comment ! ... always proud to help ! ... Paul
Paul's karts Lifan 420 best small engine site in the industry i can agree
Thanks man
Any info on the site?
Love yer channel
Paul,I am curious to know how many cc's the welded big block head is to compare to my stock head.Great info here.
What kind of HP gain is that head going to give you? What stage of upgrade is the minimum you need to do to the rest of the motor? I am pretty new into karting but love all the mods that can be done to these small engines. Also have a lot of respect for the knowledge you are passing on with your videos. Thank you for taking the time to educate us new people to the sport
How many cc are your welded chamber honda 200cc heads?
Do you have a vid on how to port
what would you charge me to do a Tillotson 212 hemi head? wont need any of the parts like rockers, springs, retainers, etc, all i'll need is the guides of course and the valves. the 35/28 exhaust?
Text me
Is this process possible with an aluminium hemi car head?
Most likely
Do you do Briggs stuff
Yes
I’ll put seats in anything .. got and own a flow bench and the equations are all the same .. builds are just a math problem ... can’t beat an engine that’s built to the numbers
Do you have to take the valve seats out before sending?
That’s nice of you to ask but it’s prob easier for us to do it. If you cut to deep you can damage the counterbore behind the seat. It’s an easy enough part of seat replacement for us that we don’t ask for this to be done before sending in a head that’s getting seats. But thoughtful of you to ask. 😊
@@paulskartslifan4206 how much would you charge to tighten up the squish on a set of v6 mustang heads
@@thejunkshredder2345 so mill the heads ? Like $75 per head. Just ship in and put amount you want milled off written on the heads in marker.
@@paulskartslifan4206 do you think it would be possible to weld up the combustion chamber and then reserface. The pistons are dished on Fords so you can't mill them alot. I'm aiming for 12:1. You might be able to add to business welding tighter pockets on Ford heads. V6 and v8s.
@@paulskartslifan4206 a good set of high compression heads for a V6 runs about 1800 bucks online.
What filler rod do you use?
Not sure , been awhile since I bought it last. Got a shit ton
5356 is better for cast aluminum 🤘
Is that 249 welded
If you’re talking about a site item. It has welded chamber and depending on item has big seats installed. Chamber is shaped and head is milled. Site item is not ported .. but this is very similar.
Just watched the video .. yes that’s the one 💪
You have to show vid of actually welding
You want to stare at the light !!!!!! Lol ... I’m blind ! Blind ! Lol
That looks like 50:1 compression wth
First
