Re: a lil nitro in the tank?

all ive heard about putting nitromethane RC fuel into a pocket bike engine will frigg it up pretty good.

remember they are much different engines. the glow engine has no spark plug, no piston rings, higher comp. ratio. if you put that stuff in a regular 2 stroke engine it could detonate too early or not detonate at all, and it wont lubricate as well because the oil is weighted for the tiny glow engine components.

all youre gonna get from using it is probably going to speed up the wear on the engine, wont last as long. and it probably wont run good either.

if money is no big deal to you go put it in your engine and tell us how it works. but it wont be like "nitro=engine steroids"


hmmm.. i have a brand new gallon of odonnel's in my shed, been out of the RC hobby for a couple years now

That's too bad, I want to use it just because it sounds cool. I got "Nitro!" in my bike dude. ha

Re: a lil nitro in the tank?

there are some kits to put nitro on i think, its a little expensive, the money could be better spent on HP parts like a pipe, filter, etc.

IIRC, nitro isnt what makes an engine "go faster", it just allows fuel to burn faster so you could lean out. not too sure about that one though.

BIS has a Nos kit with intake manifold, 2 boost bottles, tubing, handle bar trigger, and 5 Nos Co2 cartriges to feed it for around $85.

Re: a lil nitro in the tank?

nitro not nitrous
i just figured it would be like running race gas in my street bike
not even just a lil? hahaha

Re: a lil nitro in the tank?

yeeeah i get it now, the fuel itself. my bad.

well race fuel in a stock motor CAN decrease performance because, from something i said earlier, the higher octane will make the fuel detonate earlier, and it could even fire before the piston is at TDC causing pre detonation. the piston could go back down the wrong way

BUT no one i know of has put RC fuel in a pocket bike and tested performance over 2 stroke fuel. therefore in real life, anything could happen. but theoretically it wont work.

EDIT: i think the pre detonation thing may only apply to 4 strokes. because thinking of the cycles in my head, the 2 stroke has to move the fuel to the combustion chamber while the piston goes up, so unless it fires at this point when the piston is still going up i doubt there would be a problem. on a 4 stroke, compression stroke is before combustion so the valves are closed when the piston is moving up, and this pressure plus heat could ignite the fuel before the piston reaches TDC.

another problem is the lubrication

Re: a lil nitro in the tank?

Nitro is mixed with a form of alcohol and measured w/ in a glass tube with float to tell what percent the mix is, like they do with acid/water batteries. Walbro makes an alcohol carb that will run up to 10 percent. Bob's bike ran around 80 percent.
Bob Bur****, built a Funny Bike Nitro, he help me build the engine for my Pro Stock Kawasaki. We mixed it in the back of his Van, in the Pits.

Theres vids all over utube with people running two and four strokes on r/c car fuel.....its not good to do but can be done for a slight perf increase...

wanna make race gas add some toluene to high test premium fuel and add some outlaw 108 octane boost to it too....I even get a boost out of adding acetone to gas too but its sketchy to use with plastic float carbs....

I ran my 15:1 Evil Wasp cag on alky/methanol mix for a lil while...It ran cool,,crisp and killer,,,,the fuel bill was the only problem when you gotta pay for it...When I worked at the race shop the fuel was comp and alot cheaper...not anymore....lol

You dont gotta buy an alky carb to do it either...You can get a Stens rebuild kit and put in the transparent internals inside which are most alky resistant for a pumper carb....you also gotta mod the pumper spring and the fuel adjust needles .....

If still running a float carb on alky/methanol mix youre gonna have to rejet 20-30% richer and bump up the compression to between 15:1 and 17:1 compression for best results...

Youre also gonna have to flush the engine with premium pre-mix everytime you finish using your bike too to prevent internal oxidation and contamination from moisture when sitting....

Right now im experimenting with E85 in one cag and a 4 stroke dirtbike.....so far its going pretty good....

Re: a lil nitro in the tank?

anyone know how long RC fuel is good until? i got a full gallon of odonnel 30% thats been sitting in my shed for 2 years, that was a waste of $45. RC in general has been a waste to me, sure its fun until you break it $$$$. of course i dont drive slow but they dont takke abuse.

put that nitro in, even just a cap and who knows how much you are reducing the engine life.

Listen to Cam2, he knows what he is talking about. If it don't work we find a way to make it work,lol.

Re: a lil nitro in the tank?

that 2 year old nitro will be dead by now. i been into rc for about 10 years now. and tbf its not fair sayin all rc wont take abuse, my savage keeps comin back for more and my strada xt went through absolute hell when i first got it and its still goin strong. apart from an engine in my savage which dont count because they are consumables in nitro, all ive had to pay to replace was the gears in the rear diff and i picked those up cheap from an rc forum. if you buy cheap its gonna cost

sorry bout sayin that lol. my friend put $800 into a MGT 4.6 and it needed new rims servo pull start and engine head on the first day. probably more but thats all i remember

i blew the engine in my ofna ultra after about a month. and my MMGT lasted about 4 months with no damage but then eveyrthing started breaking every run and after a year it needed more $$ in parts than a new one

Re: a lil nitro in the tank?

No.

Don't. And besides, the nitromethane in the glow fuel isn't going to do squat in terms of performance because there is so little of it that is being added into the mix, plus its not healthy for the engine.

Also, nitro fuel- aka glow fuel, is basically diesel- with nitromethane- hence the name nitro.
Its high grade diesel.
The glow plug that you have on that thing is basically nothing more then a starting aid, when you put the starting thing on that top of the bugger its basically preheating the glow plug to enable the first bit of combustion to happen, and afterwards it relies on the heat caused by compression to keep the ignition going.

The two stroke uses a true plug.

Its two different types of engines, and too little you won't notice any difference, and when you start adding even slightly a sizable amount it would blow your engine. Its octane rating is too low, so you would likely pre-ignite the crap and kiss your two stroke good bye.

Re: a lil nitro in the tank?

Two strokes can naturally predetonate on premium fuel if using the wrong heatrange plug or the heads running unusually hot.Even a glowing ember chunk of carbon build-up on the pistontop can do it......To deter perdetonation when using volitile fuels retarding the engine with a rocketkey installed backwards will help out alot..........

Im running my new Goldhead 3 port cylinder with 6 port windowed piston on juiced up E85 fuel without any side effects of predetonation from the super tight squishband when running the rocket key retarded...so far its going pretty well running wise...starting-it-up is a diff story right now due to it maybe needing a custom weighted flywheel to get more revolutions per pull.............

What u wanna do is buy some cream chargers they have 10ml of nitrous in them and buy the machine and put about a syringe full of 2 stroke in the cream charger dispenser screw lid on put ya cannister in the tip twist until the nitrous releases in it ya gonna have to run a valve through ya intake manifold or ya air filter then ya just hook the hose up and strap it to the side of ya bike and squeeze with ya leg when ya ready to unload the nitrous but u absolutely have to put the 2 stroke in this dispenser otherwise u will seize ya engine so the 2stroke acts like a wet shot which is what you want I do it all the time on my x7 49cc telling ya know I can hit 80 km/h I keep up with cars in to 80 km zone near my house in Perth western Australia

Ahhh the magic of Hollywoods imagination coming into reality of imagination through folklore sold by those greedy mofos under a ruse of lies that's bought by those who believe and swear by them.LOL

Do you know theres 2 different kinds of nitrous oxide and contrary to popular belief they are not interchangeable either....??

Sweet air is 100% nitrogen based and designed to deprive the body of oxygen to get it to slow down and can go into a deep vegetive state through basically being temporarily nitrogen poisioned....

Another fact is its also used to keep dairy products under pressure from spoiling too...

Plus in-case you didn't know meat sold in stores gets treated with carbon monoxide to give it its redness and extend its shelf life...…...

Automotive nitrous is synthesized through the heat process involving fertilizers.....Sulfur is added to control the burn seeings the oxidizer is very potent and anybody stupid enough to try to filter the sulfur to huff the oxidizer synthesized from fertilizer isnt the sharpest tool in the shed...


Believe me when I say if you want power use the real stuff and use your sense too.....Ive been using the stuff over 25 years and tuning really high hp cars that run NMCA class for a descent chunk of those ...…Ive seen my share of some pretty intense carnage involving it too.

Heres a couple links outlining one of my nitrous setups done to a 49cc reedported engine...….

a YouTuber did this with the whip cream chargers he thought It gave him a boost in performance but the reality of the matter is his engine was just going leiner thats why he got a few MPH increase

this is how you gas up your ride on N20

Thats how you basically turn a very small engine into a virtual bomb from what I see...…

Kinda like Wile E. Coyote riding an ACME Rocket with more Boom than Zoom.......….LOL

How do you plan on regulating bottle output pressure all the way down to a safe pressure also and stop raw liquid oxidizer from flooding the cylinder instead of getting gaseous oxidizer with the bottle mounted like it is.... ?

Im pretty sure youre gonna need a 3.5oz bottle for what you want to do....Ive sprayed 10ouncers through golf carts....LOL



Are you going to purge the nitrous line directly into the engine or just spray n pray??

Whats gonna deliver the fuel...…;-Gravity?

My smallest solenids draw between 10 and 11.5amps each.The larger ones surprisingly draw 8amps...

Running both nitrous and fuel solenoids are gonna demand quite a load on a small sla battery alone without any replentishment...Operating them under amped will result in getting burnt out coils as inside the solenoid theres a spring that has to be forced against to get the valve pintle to open...

Youd be better off using pure medical or even the small Bernzomatic brazing torch oxygen tanks on that teeny tiny 2 stroke engine and putting that overkill n02 setup on that Savage650 or the 4 banger drift truck you have and really get to enjoy it............LOL

you right im going to need a smaller N20 tank i put a pick up tube bent up but your right its not going to work as mounted

im not worried about the amps to pop the solenoids im just going to use my lipo rc batterys to power everything ( my racing drone pulls 80 + amps at WOT )

im useing a micro fuel pump to pressurize the fuel side

there will be a manual purge valve to get the N20 down there

the jetting is at .009 at the solenoid then toned down farther useing a modified propane torch nozzle

the Arduino microcontroller controls the progressive duration of the solenoids and it's mindful of engine RPM and the WOT switch.
