That engine is screwed. You guys need to break those motors in! I literally just bought a pexmor 100cc a month ago and the break in is vital!! I’ve since then moded everything you can and ported and polished mine and changed sprockets. Mine does 60+ mph now.
What most people don't know is you can take nitromethane and add 20% to 80% gas and that will be better then ur so called nos! My bike gained atleast 5-7mph just doing this
I know how stupid you leave the chain on and then at least if it breaks down you can still pedal it home. These things can be hard to start sometimes especially when they have a few hours on them and you're starting them cold definitely so much easier to be able to pedal start it.
@@fadedbreads No it doesn't. It's the way most bikes are designed. Now there are probably bikes out there that it would but all that I have seen or had no that does not happen.
keep the stock chain on that's how you're supposed start it. you pedal to speed and slowly start adding in throttle to allow the engine to get warm first bump starting can seize the piston. you're supposed to pedal to assist the engine while it's warming up to lubricate the piston
Motorized bikes are the best dude. So cheap, highly customizable, tons of performance, awesome hobby. An actual solid mode of transportation too. It's actually pretty straightforward, just watch some in depth videos on how to do it. Just get a large frame bike if you can, not to hate but this bike was janky especially without being able to pedal 😂
I went to the ground 3 times until I dislocated my shoulder, enough motorized bike for me XD too much power and little safety and little respect from the other larger vehicles
On a 4-stroke, it's true. But on most 2-strokes, having no baffle will actually gain more power. Most 2-stroke race bikes don't even come with baffles from the factory. So an aftermarket exhaust is kinda pointless.
@@Joshtheweatherman So true, I figured this out very quickly on my 4-stroke after taking the baffle out. Not as much oomph nearly. I thought so at first, but in my head, it was only louder. I think this is a Suzuki DRZ-125L nice pit bike, good size for my first bike for sure. It wasn't as big as a regular 250 dirtbike, but just a tiny bit smaller probably the best to learn on tbh. Kinda miss it, that thing could basically climb any hill I threw at it...
Plus it's turned off lol that valve is weird, when it's between on and off, (sideways) no fuel flows through at all. But it flows through, when it's set to on or off. It messed me up at first 😂
You still need the peddle side chain to get started. Think moped... Also those wheels are going to make you wreck at speed. When you start feeling the heat on your arse pull over. It is your rear axle heating up and will snap and High side you. Speaking from experience 🤙🏻 🚴🏻♂️💨✨
@@JB_Lego I was going 60mph and slowed down to 45 when I was feeling the heat. That's when my axle snapped and half of it fell out of the bike. The wheel started violently wobbling and I took it into the grass and that is when the wheel flopped to the right and steered me to the left which high sided me onto my right side. Slingshotted me. I bought a set of Gemini's to stop that issue from ever happening again.🤙🏻 🚴🏻💨✨ ✨🇺🇲✨✝️🙏🏻✝️✨🇺🇲✨
@@Zane.Wellnitz all my bicycles have been stable into the 40s. I haven't found any safe downhill to get them any faster. A Scott Voltage MX3, Giant Yukon, Saracen Helix and some Viking Race. The bearing did eventually go in the Scott but I rode it a lot - a few thousand miles with a bafang kit - and the replacement wheel was good. A bit blustery at 47 mph due to the wind but no speed wobbles or mechanical issues. Also is the heat of a bad bearing even noticeable above the engine or simply using a back brake? Potholes however. Killed a rim hitting one at 35 mph. Nearly threw me off the bike! Thankfully on the Scott with tough beater rims with 36 spokes and not the dainty Saracen road bike.
Exactly why I came into the comment section! I was yelling at my TV screen, No lie! They have no idea what they're doing at all 😂 Then they removed the chain so they can't pedal start 🤦🏻♂️! They should've at least bought a pull starter to start the bike! 😂
"We're having a fuel issue". Yeah, it looks like it's turned off! 😂 With that fuel valve, it has to be up or down. If you put it sideways, between on and off, it stops the girl from flowing. I have the same one, it messed me up at first 😂
It has to be broken in before using nitrous and u need to be at top end speed before using nitrous so the piston doesn't explode and the nitrous kit needs to be attached to the intake for a better performance gain
I beg you to buy another 2 engines and mount all three of them on a single bike. You will need welding, but I am sure that is no issue for you. You can mount them over or behind the rear wheel, connect all of the engines to a new axle with chains and then connect the new axle to the wheel using a single chain.
That's badass brother you were smart wearing a helmet the nos was cool might have to try it I subscribed they make a double break handle that will help you out and you can get a engine for 200 bucks called a minaralli hybrid bicycle engine 7 hp a lot more balls than nos ride safe brother
Did you make the fuel mix any richer for the NOS? More oxygen = more fuel to go with it. Do you have any two stroke oil in there, cause if you don't it will kill the engine. Also, the left brake is the front in America? Weird.
You should get rid of the old sprockets front and rear, and then get rid of them peddles and weld some pegs cause there isnt really a point in pedals. Also I am getting a 50cc 2 stroke kit for a small supercycle. I have got rid of the front sprocket and am leaving the rear. It is almost done 😄
@Stinky_Couch_Pickle they are acctually very power full when you take the stinger out the exhaust and take the sponge out the air filter drill some holes in the air box and 2 holes at the end of the exhaust and pedal with the bike i swear you can get up some really big hills I think they are deacent to be honest
Now learn how to drill out the main jet a few sizes and give it more fuel. Without more fuel you're just leaning the hell out of it with the nitrous. Learn how to read the sparkplug for nitrous use and get ya a set of pin drills and pin vice, then have some real fun! Oh yeah, a GOOD expansion chamber will really wake that thing up.
I did this too with a 80cc big bore kit and a carb and muffler off a 2015 rm250 put a 32 tooth sprocket on the back with nitrous would do 100 to 120 kmph
Y’all gotta stop pestering my boys about the sprocket video I I think maybe he shouldn’t have shown the sprockets on UA-cam before making a video about them but
You guys need to put the chain back and the gears back again like when you first bought it and changing the gears when driving will take more speed and drive better. It's like having a car with a transmission in one gear put the transmission back on the bike and I guarantee you you will not regret it
I just bought one of these Pexmor engines and it arrived well but on further inspection, there was metal fillings inside the engine this concerned me and I looked further into it. I found that the engine cylinder had jagged cuts on the intake and exhaust. I sent them an email on Amazon and on their website. on the website, I have yet to know if they’re going to fix it for me. However, the Amazon side of things has asked me to provide them a UA-cam video of the engine, not working, which I really don’t want to do as I had a similar problem and it blew up, the crankshaft and scratched the cylinder. I just wanna know how was your experience with pexmor? Regards, Sebastian.
A little history. This engine was created after WWII in Ukraine (then part of the USSR), after which it was produced in Kharkov and later in Leningrad. In the 2000s, the Chinese copied it, changed the volume and shape of the cylinder, removed the spool intake, and installed electronic ignition. But the shape of the body, its dimensions, clutch, and drive sprocket remained from the original from the 50s, made in the USSR. Live with it.
People are going to be commenting on how the muffler creates more power through back pressure but that is just an old rumor the more free the airflow the better
Why did he take his chain off I'm so confused you keep your chain on so you can pedal your bike to start the engine and to have more power you need an expansion chamber
Fun fact: NOS doesn’t work by increasing engine power, it doesn’t. It’s an oxidiser, meaning you can add more fuel than you could have if you used the air alone. It’s also why top fuel is called that, nitromethane has its own oxidiser so you can just jam it in there and run suuuuuuper rich.

remove the plastic cap that you used to put the nos in (the bike wil have more torque)
Get some marvelous mystery oil, use in 2 stroke. Coming from mechanics that make bank breathing. Etc
Great videos. you deserve more views.
You should leave the normal chain on so you could pedal and start it like a moped
