Again another mod that gained you 25% more top end speed. These videos are awesome little experiments that can allow those starting off have an actual idea of what to expect when the do this or that. Not to mention you are doing off the shelf vs homemade. Something everyone can replicate vs watching a mechanic of 20 years hog out their their intake and exhaust, replace valve guides, Drill out their sponsors piston's oiler ring grooves, fly cut 1mm larger valves, turbos, ecu's ,so on and so forth.

If you have a non hemi 212 check out the stamped 1.3 ratio rockers especially if your already running a low lift cam the stamped 1.3s drop right in for 20 bucks thats what i cheater power as they look like the stock rockers but provided the extra lift especially to a untrained eye you could really make some big power on a stock looking set

If you change 1 thing its gonna effect another so you will have to compensate for your changes

We're running a 120 jet on our flat track mini. It's definitely popping when you let off throttle. This knock off mikuni does not have the needle valve adjustment clip. You think a 130 would be ok? That's all I have at the moment.

[@Black66]

If you are running a VM22 knock-off, it has a clip and needle inside the slide for adjustment. At least all my VM22 carbs have an adjustment. You must be running a different style or brand carb. When you let off the throttle, it runs on the idle circuit only so it gets lean and Causes a pop. That's ok as long as it runs well under throttle. You can get it to go away by richening up those circuits A 130 could be ok. It's hard for me to know for sure because everyone lives at different altitudes with different engine combos. So everyone's jetting could be different. I would just try it out and see how it runs.

Strings are cheap but for the cost of a stage 2 kit if your running stock 196 buy a ducar or a Tillotson 212e or 212r you will save money in the long run

If you are running a TAV with a 19 inch tire valve springs aren't going to help anything. The stock springs can easily handle the RPM you are topping out at.

Only the internal governor will remain if you add the slide carb because the slide carb doesn't use the stock throttle linkage.

@@Black66 would it be fine with the internal still in the engine or would it be at risk

[@Black66]

@@Minty8901 There is always a risk. Its always recommended to take out the internal governor when you no longer are using the external stuff. Just more stuff to potentialy break. With that being said I havent opened the case on this one . No problems so far. I have a Coleman 196 that I have ran for about a year now without a problem with the internal governor still in tact. It's still smart to remove it though.

[@Black66]

If the governor is still hooked up it will stay the same. If you disconnect the governor You should gain some. I gained about 8 MPH on a Hemi Predator just by changing springs. It should be ok. But there are no guarantees with any of their stuff. Just the nature of it. The thing about it is even if the engine will rev that high you don't have to drive it hard all the time.

[@JNC1973]

There is something majorly wrong with my bike. I just put a brand new non epa carb on it along with the mod2 cam and 18 pound springs go to test ride it and even floored it could barely move me with the slightest incline. I'm guessing it has to be the gearing on it cause i got a 44 tooth sprocket on the read and in front i believe there is either a 11 or a 12 tooth sprocket. I knew the smaller the rear the less get up and go it would be but i didn't expect it to be this bad to wear it would barely go at all. I don't think i got it over 10 mph. So i'm think maybe trying leaving the 44 tooth on the read and changing out the 12 tooth in front to a lower tooth like 9 tooth maybe and seeing how that rides. If that don't work i'll just lose the 44 tooth and put back the stock 50 tooth. And if that don't work then something else entirely must be wrong with it. I did accidently rip a small corner of the side cover gasket when putting in the mod 2 cam and have not changed the torn gasket yet with a new one but that wouldn't really cause a huge power loss like that i wouldn't think ? also valve cover gasket is not the best either so i got a new set of gaskets i will be adding soon. And the stock bolts that came on mini bike just suck in general cause several of them broke in half while i was tightening them down. Broke a valve cover bolt, broke both front of gas tank bolts/studs and broke the chain adjuster bolt next to rear tire. All broke just from tightening them lol. Like what the hell man ? Made in China !!! ;)

[@jtaylor9355]

Ive never broke a single one off of the many engine ive torn down and put together. Try to run the nuts or bolts up flush and then a 1/4 to 1/2 turn more. Unless you torquing bolts like the the head or side cover which ha e torque spec they suppose to be tightend to. And if your running a 12 front with a 44 rear that gives you a 3.6 to 1 gear ratio. Thats way to high. Go back to the 50 tooth rear and a 10tooth front or 8 tooth if your in the 200lb plus club.

[@dustinmalone4707]

You're going to want to change all gaskets. Sounds like a compression issue. Best to use good, quality gaskets too.

How would I make a predator 212 go like 50mph? Would what I have to add to it?

[@madness_-yg3lw]

Gearing gearing gearing its literally everything a stock engine can go almost 50mph but a built one only go 60 its depends on your gearing and the max rpms you wanna turn then gear it around that for 50 or 55 but the best way to go faster is to change your gearing you build the engine go what ever max rpms you wanna run and look what gear ratio and tires sizes you need to hit your speed goal

[@madness_-yg3lw]

The engine its self to build it reliably your gonna wanna billet rod and a aftermarket flywheel rated for higher rpms i personal prefer the billet 32° flywheel because if say you only wanna turn 7k ar first and you buy a flywheel rated for 8k if you run the engine and realize you wanna turn it harder then 8k then would have to replace the flywheel again save up and get the billet it as it will save you in the long run and give your engine the potential to rev higher if you so choose its what i did to build my 212 was over build incase i wanna go for more rpms witch i have found my self doing going from 18 to 26 atm and possibly 37lb single or 60lb duel coil springs because once you get the itch for rpms you will wanna keep turning it up especially if its still pulling
