Stretched Mini Bike With UNDERGLOW!
Id say i'm about 50 percent done with this build. It is not the same Motovox as video (Progress #1) ;that bike is on my profile pic.

I wana see you get 80+mph
U need just one. If u run a pulse pump
whats thay stuff you used for the vents from the side cover to valve cover
What size head gasket did you use with the flat top piston and extended rod? Or just oem gasket?
He said .027 inch
do I need to vent pls answer I have a stage 2 kit on my motor DynoCams MOD2 Cam ,billet fly wheel ,billet rod,rockers,push rods chromoly,billet lifter,
vent asap, been needing it at the flywheel
1 50 dollers 😂😂😂
Interesting with the vent, from side to head to catch, when im building my piece, im also gonna do this, nice built btw!
Bro gained 100 horse from this lmao there’s no need in doing this people don’t waist your time I’ve ran an built these for years these kids are just doing for looks
If you have a big block with a 69mm crank you should vent the block.
I have a freshly built engine 265 cam billet rod aluminum flywheel 26 lb springs but only hitting 50mph I think I’m reving around 7,000 rpm but not sure if it’s my ratio could I run a 18t clutch with a 40t rear sprocket to gain some speed
And the reason most people remove the Governor gear inside the engine is so it doesn't come apart and cause your performance parts to be destroyed it is awesome that you took the time to build your own engine but but you have the reasons backwards the governor is removed for reliability and the oil sensors are removed for performance reasons many other people building these engines they don't really know why they're doing certain things they're just copying other people and think they know why they're doing it upgrade job on the build
The reason most people remove the oil sensor has nothing to do with it coming loose and creating an oil leak nothing at all to do with that the reason they remove the oil sensor is so when you are on hard acceleration it doesn't push all the oil to the back of the engine and make it cut out because there is no oil on the sensor
How many teeth did u have on that clutch bro? Cuz the sprocket is a 40 tooth right ?
No camshaft?
what gear ratio are you running currently, what is the top end looking like?
those breather tubes are FAT bro
What does venting it help or do? I'm asking cause I just got a 212 tillotson on a bicycle and I love it! I like working on it and want to make the best I can. Thank You for the video and hopefully the response to my question.
Relieves pressure inside the crankcase. It’s necessary for bigger cams and even the stock one as sometimes the pressure can be too much and blow the oil plugs out or a gasket. Better safe than having to replace more expensive parts.
Why two vent lines...? Looks very good
1 or 2 shouldn't make any significant difference
What would the front sprocket change?
nothing really? most bikes will typically only have a 12T and a 10T depending on what size chain you are running
Awesome
It's not the engine that gives up to 80mph it's the total setup the chassis the gear ratio it's a combination as a hole.
My predator jerks back and forth after I put on the 14 clutch and the 60 tooth sprocket an I changed it back to 65 an still does it I’m so confused
It is because that gear ratio is way too low. For instance, my clutch was burning at 40/12 = 3.333 ratio and I only weigh 160lbs. You are trying to do a 4.2 ratio and you may weigh more than me so that may be your issue. Try lowering the teeth on the 14t to a 12 but it also could very well be another issue that is causing this to happen
you need check vavles because on the intake stroke it will pull oil back and gases you dont want into combustion.
how to use them? why not only 1 line from block to head with check valve, and one on head with check valve to outside?
The only way you can pull oil into your combustion chamber is if you have valve stem seal leak or bad rings. How else would oil get in there without a positive crankcase setup?
Make sure to always clean out the shavings from the engine even if it’s one you don’t need you never know I might just use it and remember when it’s taking a big shiddd ohh yeah I didn’t clean it out I learned the hard way 😊
dont need a cam because you want to get bigger springs
Wow
Bro I need that part list.
in the description
what clutch are you running on this?
It’s the Hilliard I think 10t
Why not use wheel bearing grease?
How much is the payment for the honda 16hp engine?
Maybe a dumb question. Why could you not vent off the pre drilled and tapped oil fill holes/caps?
Do you mean the hole in which the oil sensor is placed?
hes talking about the stock oil hole where the tube goes to the carb airbox its the hole on the side of the motor @@JulDeeMotorSports
Are you referring to the original PCV .?. I just stumbled on this video. Is the original pcv left alone.? I'm assuming have to vent to atmosphere or you blow seal somewhere ?. Right,.?. And this isn't for case pressure, it's for oil return, correct?.
alot of people get this wrong, but welding the head or gettting a flat top piston or smaller head gasket will not increase compression, it will stay the same, its all about compression ratio. without a stroker crankshaft all those very expensive parts will be useless. the first thing to get is the stroker crankshaft then add all the parts on top of it.
😂yes it does having 30 thow less head gasket adds compression u might wanna check your facts
That's exactly why people try to get zero deck high with race engines it raises compression
Dude. Just drill and tape. Goddamn I wanted to kill myself. This was pure torture.
Removing the oil sensor also slows it to hold more oil
Where do you get the bars from ?
Would you get the same results from a hemi?
why do people think 80mph is out of the question its all about gearing and rpm im sure it coulddo 80 with the right gearing
This dude talking a bunch of sh*t 80mph and only turning 5200 rpm BAHAHAHA
What if you don’t run hemi ?
dont matter
1 year later… it never came 😞
I sold that, sorry. It was a hasty sale on my part, the guy wanted me to make it white and red so I discontinued that. Don't worry, I am remaking this after I finish my new db30
@@JulDeeMotorSports gotta start posting again
@@559Minibike_AV Don't worry bro, I'm about to come back stronger. I recently picked up a bunch of filming and editing equipment so I don't have to film everything and edit on my phone. Stay tuned, making some new custom performance products and new videos. Im thinking a few more weeks and you will see me consistently back on here
@@JulDeeMotorSports hope to see a vid 💪🏽
Hey I might build a 212 and love your engine if you can could you maybe send some links to the upgrades on the engine Thanks 😁
how did you connect those leds
Damn bro! You got it..nice tutorial!
Just drill and tap top of front cover and top of valve cover, add barbs/hoses for crank case relief? I guess pressure exits from the stock vent on valve cover?
what is a front cover? Do you mean the block?
The proper way to remove the Flywheel is to screw the Nut on so it's flush with the end of the shaft and then whack the nut with a Hammer once or twice while prying behind the Flywheel at the same time with a Flathead Screwdriver. But I'm sure you know that by now lol. What happened to your Channel you haven't made any videos in the last year or so ? Gave up on it ?
No, I am sorry for not making videos recently. I have so many unedited videos ready to be worked on but I am planning on scaling up the production. I am planning on remaking most of these videos since I have learned a lot more over the last year. Stay tuned and subscribe if you want to see my future videos. I have more bikes coming that should be the firsts of their kind in the minibike community.
what cam did you run
Size valve n carb bro?
So what arc rod # did u use in the build with the flat top
Why do you need to put 2 lines for venting the crank case in to the head cover and then 2 lines to vent to a catch can? Won't 1 line, or 1 larger line, do the same job and be half the work and half the potential for failure down the road?
1 line will work. Personally I like the look of 2 lines and I wanted to copy the billet side cover which also allows two lines.
I just run 2 into1 vent line with a large diameter up to triple tree area with a gauze filter. No catch can needed as oil doesn't seem to climb that high anyway. Catch cams are only for race tracks
Been doing these motors for 6 years and this video is amazing
thanks
Maybe a dumb question. Why could you not vent off the pre drilled and tapped oil fill holes/caps?
I would suggest a 265 cam and add a one way valve to the oil catch can.
256 to small
