Push Rod Lengths and Different Rockers (Predator 212, Clone 196cc, Go kart racing, Mini bike racing)

[@darryllawrence2530]

Watching in 2024. Best tutorial discussion on Heads, Camshaft, Push rods, rockers, lifters.

[@predator_boiz336]

I been running a mod2 on 1.3 stamped rockers with stock pushrods and stock guide plate and 26 Lbs springs for over 1500 miles soo far lol, it’ll top out at 76 mph on the minibike , gonna get me one of them billet guide plates

[@NubsWithGuns]

Is that on one of the bikes on your channel? We need more mini bike stuff, I'm gonna go check out your vids.

[@diegosotorojas6593]

What gear ratio are you running? I have same setup 53 rear 12 clutch. But 22lb springs and I am floating the valves around 68mph lol

[@predator_boiz336]

@@diegosotorojas6593 I run a 12/53 but I run 26 lbs springs soo no float

[@Nouri_TV]

This video is gold thank you ARC

[@larryfisher]

Ohio watching all your videos 😄

[@larryfisher]

your the only one that says use a little shorter pushrods with ratio rockers on 1st gen predator n how to with out having all the dial indicator and the pushrod tool,thank you so much I know you're not responsible,but very helpful n informative

[@larryfisher]

and I watch n learn so much watching your vids

[@sonnywhitlock6220]

Do you have anything on cut to length push rods using ratio rockers on a 9mming predator

[@MesaMinis]

With +.060 valves I would need .060 shorter push rods or the correct geometry right?

[@theshredcouple]

How did you fit the .310 cam with 1.2 rockers in a hemi? I have a .308 with stock hemi rockers and I’m less than .090 valve to piston clearance on both intake and exhaust. Shorter rod? Dish piston? Fly cut piston? What’s the secret?

[@jimmycooper7248]

Silly question perhaps but on a stockish motor do you ever use a stamped ratio rocker on intake only? Good video, thanks!

[@Nouri_TV]

I got a 1.3 stamped on the intake only stock on the exhaust works great.

[@Strict30]

Is it a must jody to have billet side cover? Ill be 32/28 head 285 cam with gage 1.2 and 60lb duals???

[@eddiedoran7427]

I bought a set of roller rockers from OMB, not sure if they are ARC. One of the rockers has a pointed end on it. Which valve does the sharp end rocker roller go on?

[@eddiedoran7427]

Exhaust or intake they are steel, not aluminum.

[@spikemandan]

hi i just bought nr roller rocker 1.2 rockers for a 212 hemi is the stock push rod length a bit to long for what im trying to do because im having issues with getting the darn thing together

[@jimmyalley792]

Did you do a video on shaving the head and block.

[@yuknasty9199]

Can you not shim rockers for better angle

[@donraabe3529]

Stupid question for you Jody, what do you use to measure push Rod lengths

[@Robbobshiskabob]

Calipers

[@chuckhuff7123]

How much work schedule does a Ballroom dancer have?😮😊.

[@crazyjesse11]

Now with the shorter push rods would I also need longer lifters?

[@EnginesbyAustin]

No

[@chriskeevert7332]

If I changed from my stock rockers with 18lb. valve springs, to champion "hd" shaft rockers (1.0:1), would I have to change pushrods? I have a mod2 cam short fin billet flywheel and 18lb. springs. If I would have to change pushrods which ones would I need and would I have to do anything with the valve cover?

[@weskartingnl821]

Hey chris have the same question what length did you use?

[@chriskeevert7332]

[@brandonmurphy3996]

You ever need to have 2 different pushrod lengths? I have the exhaust valve stem about 1/16” shorter than the intake one. With the same size pushrod the intake spring compresses fine but the exhaust one seems to bind and then bend the rod

[@arcracing7637]

The pushrod length will have little to do with coil bind. The spring install height is what controls that. You will either need to cut the spring pocket deeper to give the spring more height, use a longer valve or cut the valve seat to sink the valve in the head to give you more height on the spring side.

[@samstewart4807]

Why do you run such a big ex. valve?

[@arcracing7637]

The size of the exhaust valve needs to be with in a certain percentage of the intake, depending on cam and head work.

[@edgualdino628]

Hello just a mini bike an I gonna do a predator swap whats a better to get most power hemi or non hemi an like in price an horsepower thank you just subscribe

[@NubsWithGuns]

3 years ago but, Anything with a clone taper shaft AND a straight valve head is easier to get parts for, still. That leaves out both of those.

[@eddiedoran7427]

Lost the needle bearings 2nd race,destroyed my engine. Just saying.

[@eddiedoran7427]

I had the same thing happen. Billet aluminum. USE the STEEL ones!

[@Mroswaldo16]

So why go big cam if your going to require shorter rods? That takes the point of going big cam, to get more lift! Just get a cam that gas the right require lift before hitting piston on stock valve kits

[@NubsWithGuns]

Think of the stock push rod being too long instead of the new one being "shorter".

[@built2last31]

turn your phone sideways to record in full screen!!!!! thats why i don't watch too many of your videos
