My non hemi box was sealed, got it home and had a Hemi in it and even had the non-hemi part number on sticker on blower. Make sure you mention to your viewers, to look through the hand holds and see what valve cover to verify what’s in the box. Problem is I already ordered an electric start kit for a non-hemi! 😢
Thanks RB. For those of you wondering why he added the extra 1.5 thousandths (.0015) after he had it perfect he was splitting hairs as he knows he’s got to keep .003-.005” gap between the lash cap and roller so he was using up some of that to keep that valve open just a bats ass longer. I can see the value for this on intake but not really for the exhaust side.
Hey Red, that was some good knowledge to pass out to builders. It will help them to build better engines wh1uich in tun equals better, safer go carts! Keep the videos coming, youcannot have to much information!
Wow tillotson 212cc Its only my dream this kind of engine because in my country Philippines it's very expensive. this engine set up if i use to my racing boat wow it's very powerfull. Here in Philippines the competition we call it pioneer national bancarera..
Damn your springs compressed are almost binding . Mine are. Have to cut seats but was concerned that cutting the seats wouldn’t suffice . Now that i see yours i feel better.
I know that this is a bit of an older video. What pushrod size would a "internally" bone stock 196cc predator use, I'm looking to change valve springs an pushrods all the advice helps a lot
If the pushrod is too long for example +.004 the total lift would be greater than .369. In that case you need decrease the adjustable pushrod. Correct?
You said that you have 1.2 rockers. I have the Tillotson Racing head 225RS and can not find the rocker measurements like you have to do the equation. I have the HOT265-NHP cam. I do have the adjustable push rod tool. All my parts are from GoPowerSports. Thanks for any help.
I've wanted to do cerakote myself, but I'm worried about the durability of the coating. Do you have any motors with a lot of hours on them with cerakote on the internals? If you do can you do a tear down on one to inspect as part of a video someday?
I thought you were showing us how to utilize “cut to length” push rods. I get that for this application you’ve found off the shelf pushrods that would work but….show us how to use the cut to length ones plz!,,,
Based off of your oil cooler test video. Have you ever ran methanol in one of these engines? I bet they would run a lot cooler. Just an idea I had at work today.
I’ve got a 3” tillotson at the machine shop now that will be a methanol motor. You can run a lot of compression and lead but be prepared to burn a lot more fuel.
About .000 % of the time to be honest. I’m surprised he told us to buy the precut set for that engine combo as he just said every head and block and valve seat machines area have tolerances. They all different. But the self sizing and cut yourself. Practice on the stock pushrods.
Hey Greg, with the milled head, high lift cam, and ratio rockers, do you ever do a valve to piston clearance check? Is it necessary with these small engines? I have been binge watching your videos lately and haven't noticed you doing so.
Wats up redbeard my name is juilio and I'm from Harrisburg Pennsylvania and I'm a stage 4 cancer survivor. I got into mini bikes and I have a baja mini bike that I need help working on because I don't know to much about them
#RedBeardsGarage if you have a performance head, and it was milled say .003, does that effect the # s you calculated? you had a .308 cam, and 1:2 ratio lifters... so you did .308 x 1.2...just curious if a milled / shaved head would make those numbers fubar since that wasnt in the equation. I mean I seen you get them numbers on the dial gauge, but its making my head want to explode for some reason
@@WARIIIIRONWORKSyou have to measure unfortunately. The blocks, heads, valves, valve seats cut into the head all have a tolerance. What works for some will not work for all. Sadly you need to measure like he showed us for EVERY application if you want it right.
Hello there. Not to change the topic on the cool video here, but my carburetor on my small engine which is a duromax 7 hp it’s spraying gas from the top of the carburetor ball where it connects to the carburetor itself. If anybody has a solution fix this issue please comment would be very much appreciate
What i missed over here: the size of the valve gives how much it needs to open. The max flow of a valve is on 1/4 of its diameter opening up. You can get the max lift out of your cam when pushrod and lifter operate around a 90° angle. Check the lift of your cam and lower the lifter halve that measure. So the lifter operates between for example 85 and 95° Then check if it lifts the valve enough the get max flow trough. Every opening up more is lost power, power needed to open the valve.
I’m not sure what you’re trying to say here. Are you suggesting someone who bought too large of a can should compensate for this by measuring the valves diameter and deciding by 4 to get what their max lift should have been and then adjust pushrod length to ensure you get less lift than the cam was made to provide? Then in that example how would you add duration to this theory as the longer a valve is open at any height you would get more flow through them. 🤔 I’m just not sure where you wanted to go with this outside of making certain the rocker arms and push rods are at 90 degrees but even that is slightly debatable with ratio rockers as they tend to lean slightly backwards towards the pushrods at a slightly open of 90 deg angle per Gage roller rockers website.
@@ol-man-duffyj688 sir make a circle please. That 1/4 diameter gives the flow through the opened valve at that its maximum. Lesser lift means lesser flow, more open wont give more flow trough. How long the cam keeps the the valve open just gives the amount of time gases or air can get out or in the cylinder. The remark about the rocker arm: at 90 degrees in the middle of working gives the least possible angle for the most lift. And: the lift of the cam and diameter of the valve should be matched.
@@henkoosterhof5947Interesting ideas do you have data or a website I could go read and learn this as well? I’d like to see if there is actual calculations to best cam range for certain valve diameters. As we know bigger isn’t always better. Bore size has a factor in this as well as you increase valve diameter and lift. Thanks for sharing more I appreciate your insight even though I don’t quite grasp it all. That’s how we all learn more 👌🏼
@@ol-man-duffyj688 no sir. Things i learned at the training college for marine engineers. It was in the dutch scoolbook for engines, but i dont know if they are available where you live. But try those sort of books please.
If you don't know what the cam lift is, put your dial indicator on the pushrod side of the rocker. Zero the gauge and roll the motor over until you see max lift. That will be your camshaft lift.
Hey red beard umm got a question. I own a 670cc predator buggy and need help and wanted to know if master of the predators could allow or make it easy to communicate about my predator issues thanks
Hi Red, I have the 224cc. Predator engine and used all of your parts in your video ruclips.net/video/K5nkGiTAyuM/видео.html Really close to being done and wanted to get my push rods cut the right size. What was your push rod length from that build? Really appreciate if you could get back to me when you get a chance. Thanks very much!
Go Power Sports is a rip-off when it comes to these roller rockers. I can get myself a set of roller rockers, which are 16 in a set for a small Chevy for $182.95. They want over$200 bucks for just TWO rockers😂😂😂😂. They are taking advantage of people with their overpriced products. For the price they are asking, they need to throw in 20 roller rockers. I'm sure the ones for the Chevy V8 are much stronger and built better than these at power sports, and yet they are cheaper priced. This is price gouging. Those flywheels they are selling, the same thing on those. We are all getting ripped off. It's not right people. I built engines for my muscle cars and then I got into this mini bike engine build but I'm slowly but surely getting out of it because of these rip off prices on these cheap parts.
I'm going to ask you a question off topic Yamaha golf cart until 357.cc do you know of any companies that make anything for them to get a little bit more power out of them without going to like what you all do at it's jacked up with 20 inch tires and I can get it to roughly about 20 miles an hour on flat ground

On the these motors can you add a lighting coil with a aluminum flywheel?
Nope. Not on any billet wheel manufacture to date
Could you make a video on how to set up the dial indicator
Doctor Red Beard the small engine expert...
Just sharing as I learn but Thank you for the kind words!
Great vid as always👍
Another great video.
Based off of your oil cooler test video. Have you ever ran methanol in one of these engines? I bet they would run a lot cooler. Just an idea I had at work today.
I run methanol in two of my engines a 200cc and a 236cc and it definitely runs cooler than gas
That's one of the basic common knowledge facts of methanol fuel - runs cooler.
I’ve got a 3” tillotson at the machine shop now that will be a methanol motor. You can run a lot of compression and lead but be prepared to burn a lot more fuel.
That´s just great! Thank you!
If you're shooting for .000 accuracy, how often will a precut .00 pushrod work?
About .000 % of the time to be honest. I’m surprised he told us to buy the precut set for that engine combo as he just said every head and block and valve seat machines area have tolerances. They all different. But the self sizing and cut yourself. Practice on the stock pushrods.
I think it about time I do the something 🤔
Hey Greg, with the milled head, high lift cam, and ratio rockers, do you ever do a valve to piston clearance check? Is it necessary with these small engines? I have been binge watching your videos lately and haven't noticed you doing so.
that's a good question why no answer ?
I don't think he ever does. All his parts are free now from go power sports so he doesn't give a shit.
I don’t see him doing it but it is a necessary thing to do Espically on hemi motors because they have way more valve to piston clearance issues
I think as long as your cam lift is 400 or below you are ok ,I haven't seen one yet touch
When will you make the video to make the proper length pushrods and put them together?
And great job red beard this is really interesting
Nobody said there would be math!🤯

Will a 212 engine have enough power for a golf cart
We are going to try it this summer.
Where did u get the measurements for the max amount of length?
Cam lift x raito or rocker used .... .308x1.2= .3696

Supercharge or turbo the Duramax 999
This only works with knowing the cam spec? But if you're doing this on a stock cam....? How the heck would I know the right lift?
Just use stock
@@trentstreichert2217 are you trying to make sense?
If you don't know what the cam lift is, put your dial indicator on the pushrod side of the rocker. Zero the gauge and roll the motor over until you see max lift. That will be your camshaft lift.
sorry for my stupid question, but if you got stock rocker arms and a modifeid cam, you still need to check push rods measure?
Sir you missed your cue. Said 369 twice! And it was not followed up correctly!!!
What? Probably something ridiculously niche.
