I bought one of your bullet train engins and I love it. I sure would like to get a expansion chamber for it. I'm get 40mph out of mine with a 32 tooth sprocket on the drive.

I like your old Typhoon in the background! I have one just like it. Same color too. Enjoyed the video as always.

That was a nice yard sale find. 😊

I have wanted to have a bullet train personally. I have used the 2 strokes for several yrs now. I ride to & from work all year long including winter. Winter is what stops me for the most part as I am afriad that having my bike out in the cold for 14hrs would kill the battery, other than that with the engine bieng one peice I am scared that if any one place were to crack then the whole thing is just spare parts. I have been using the stage 4 since BB has not been able to get the 80cc Dragonfire back in stock. The Stage 4 is a fine engine & will be my goto if the Dragonfire is no gonna be coming back(unless I can find one elsewhere.) Thank you for your videos & the time you take to make them.

Appreciate the kind words 🙏 I’ll definitely test the bullet train this winter to see how the battery hold up in the cold. My question would be if the cold cranking amps are sufficient. I’ll do my best to keep you posted.

@@tonytaylor5087 The BT80 engine has plenty of potential, BUT it lacks basic performance parts, like the expansion pipe, windowed piston, reed valves, variety of carburetors. AND ALSO, IT WOULD BE GREAT IF THERE WAS AN ELECTRIC START VERSION OF THE BT100 WITH CENTRIFUGAL CLUTCH LIKE THE BT80 !!!

Appreciate you letting us know that. My experience has been the same.

Having had a Bullet Train, I would never have another pedal start engine. Bullet Train is hands down the best quality I've ever seen in a made for purpose bicycle engine. Sure the 4 strokes are even *more* dependable, and yes the Bullet Train is not the cheapest option by far..but it's pretty hard to beat.

Please start making at least exhaust for the BT PLEASE. I love the engine but the limited exhaust (just one) options are the downfall of this engine.

I thought 66/80 were 2 different engines . thanks for clearing that up! so i got a 66cc engine in reality

I just bought a 80cc Bullet train electric start engine that I plan on putting on my Schwinn OC Chopper Stingray. I have the boost bottle and intake manifold for it, however there are currently there are no exhaust options for the engine but I would love to have something like the voodoo performance exhaust that could fit the engine as well.

That was a pretty good video Tony.Thanks for covering all the highlights and differences of the 2.Is the Bullet Train muffler the same 1 they use on the 85 'chainsaw' head engines?It looks like it'd fit well.Btw,I like how you've customized the B-T bike.I think the B-T would be the best choice for a 3-wheeler conversion too.Have you built 1?

Thanks brother! I’ll have to check out the chainsaw head to see. Nope, haven’t done a 3 wheeler but I’ve seen plenty of them.

Nice new vids!

I would love if they built a version that was compatible with all the parts the other one has such as jugs and heads, if you could make an electric start kit for the modable engine that would be perfection :D

If there was an aftermarket upgraded chambered exhaust for the bullet train electric start. I’m in for a few. I have three of these engines. One of them has a windowed piston upgrade and Oz reed Kit it goes pretty good. It’s on my Schwinn trike.

Where did you get that expansion chamber really looks nice

Hello, do you guys have replacement parts for the centrifugal clutch if it goes bad

bro i have a bt 50 mm piston and that joint is nice but my rings broke and i dnt kn where to get em .i order some and they were to fatt but if i didnt give it full gas for 45 min run it prob would have never happened .i like to see what i can do to eng, before they break and i must say the bts are sweet .just need a 52 mm piston

And it has a pull start no way right on I'm really buying myself the bt80 cool thanks brother for this video your awesome

Is there a way to mount the bullet train to the top of the back tire, in the place a storage rack would be?

Hey tony is it better to break motor in with regular muffler or expansion chamber ??

does the bullet train have a higher top speed than the 49cc 4 stroke? manual clutch not legal in ontario canada(with pedals) and i can only get the 4 stroke to get to 50kph. ideas to improve speed? i have a 40 tooth rear sprocket, acceleration is rough. 44t sprocket noticeably better acceleration but 40t didnt really notice a difference in top speed but def noticed slower acceleration. 4 stroke also seemed to go faster when it was new...any ideas why thats happening? centrifugal clutch need new pads or something? legally im allowed to go 70kph.

I'm looking at both but which one is more reliable for long term use

I really like this video! I personally like the stage 4 better because I like working on/ upgrading my bike. The only thing that I don't really agree with in this video is at the end when he says that you have to pedal the stage 4 "quite a bit". At least with mine, I have to pedal maybe 4 or 5 rotations (at most) and the bike will start right up, and I have to pedal less than that to get going from a stop when its already running. I'm not trying at all to hate, I'm just sharing my personal experience.

Thanks Tony. Yeah, l got to say, l bought my second Stage 4, still in the box, because the first one is better than the 2 first engines l bought from guy that works out of his house. The Stage 4 with the performance carb and the 44t sprocket no doubt pulls better in the wind, up hill, and pulling my WeeHoo single wheel trailer loaded with groceries, 10gal gas, propane, water or just hailing my backpack of tools and stuff.😺👍☑️

can you make an adjustable cdi to control the spark speed. instead of shavings the woodruff key and make a custom magneto and mag so we can run brighter light and charge a battery

what can i do to go fast in a 1/4 mile i have 100 cc, you have a grate show

I want the Bullet Train engine, but with a higher performing exhaust. How would I go about doing that?

Does the bullet train leaks oil from from the side where it’s needed to lube tue clutch?

I am going ro be building a bike this summer (2023) I want an electric start , looking at the bullet , but would want a flexible exhaust and a jackshaft attachment

Hey Tony, with the Bullet Train motor, can you jackshaft the motor? Thank you.

Hey Tony I never thought of using the Bullet Train motor because of the wide cranks, I didn't like the idea of having to change out my cranks as I like them as they are. But I have a custom Bike build that I am doing that may just be perfect for one of those motors as I may not be able to crank the bike up to speed just to start it. My design requires the motor be mounted away from the cranks. I also had no idea that the Bullet Train had a centrifugal clutch I am now thinking that it might be the perfect motor for me, At least once I add an Alternator. Thanks for the heads up about this motor.

You'll want 4 stroke oil for the clutch. I used Valvoline ATV oil that specifically mentions use with clutches. As for the amount, I think it's 150ml (about 5oz)

bt looks sweet but i dnt get why didnt they up the bore to 52 mm piston.the lil 48 mm pistons are way to weak

I just started building a bt80 bike and I'd just like to know what performance parts are usable on this kit. It would be a great option to produce an aftermarket jug that's 2 piece.

@dmoore0079

Жыл бұрын

Unfortunately, none of the aftermarket performance stuff will fit the BT80 without modification. This is due to the BT80's unique intake bolt spacing (35mm vs 40mm) and the BT80's unique exhaust flange design. There's a possibility of certain moped exhausts that might fit (Honda maybe?), but you'll most likely have to do some cutting/welding to get anything to work. For adding a reed valve, just fill the existing bolt holes in the reed body with JBWeld and drill new ones with the correct spacing. As for the windowed piston, a 47mm "low hole" windowed piston is what you'll need.

I have an anbull engine with the same exhaust as the bullet train and I wish they had a easy upgrade or a adapter so I don’t have to weld one.

Why are Torque Converts not more commonly used?

I've got another question for you Tony, Lets see if this one baffles you? What are the odds that I can change out the cylinder on the Bullet Train with a stock cylinder off a regular motor and then upgrade to a better head??

How about drag pipes

Which one is faster?

You know why the true reason the engine is described 66/80cc ? because the 66cc shares the same cylinder barrel (entire engine actually) as the 80cc.You have an option to turn it into a 66 or an 80 by only needing to change the conrod. That is the only difference. The rod is a touch shorter in the 66 but they both share the 47mm piston & barrell. That is why its called a 66/80. Its not an 80 overseas & 66 in US.

I have a bullet train the full crank broke on it and the wiring harness broke within switch

Would love to send you photos of this bike

what is that on the stage 4; The gear is sticking out from the clutch breakerbar area!! Thats what I should of done in the begining!! I bought a jackshift kit, I tried everything!!

Which one has more maximum horsepower and torque and speed?

I would like it to have upgradeable mufflers for it open pipe mufflers

Why are you not offering 100cc

Build the exhaust for the bullet train!

how well can you just pedal the bullet train as a bicycle?

Is there a Bullet Train engine without the pull start? Just electrical start, that way it's not too wide.

What is the break-in period for one of those engines so I don't blow the damn thing off the get-go

Better exhaust

The pull start sucks it’s junk I just sealed it up I’ve had mine for 2 years no problems except carb,plug,and some electrical issues that’s it but it’s reliable

2 stroke is just a simpler engine with no cam and valves like the 4 stroke. Maybe if more upgrades were available I would consider it but there are just so many things you can do to a 2 stroke. Everyone is making some Frankenstein monster

I use this Bullet train electric start engine from bike Berry and I have an o CC chopper add. It's done up to the maxs perofmace i can get so far that even got break lights running lights everything modified exhaust even has a reed valve. I'm. Trying To do a booster bottle has performance. I wanna. Put The performance piston. In it? I've modified a lot on this bike and even looking at doing a nitrous. So I would like for them to come up with more performance parts because I've been able to do so much with this kit that I couldnt do with any. Other kit. It's making and no matter the mod it always hold tuff and reliable I can do more then engine performance with this kit

you can turn any chinadoll minarelli hybrid into a bullettrain

Does it come bike and all

What speed do you expect to achieve with the Bullet Train? What has your top speed been withe the stage4?

@tonytaylor5087

Жыл бұрын

Not sure top speed w/ BT yet. I’ll test that once it’s broken in. The stage 4 is capable of 30 to 40 mph depending on your setup.

As far as performance parts go.if you build it,they will come. Pretty much…

How fast

So is it 60cc ? Or is it 80cc ? 🤷🏽‍♂️

The bullet train looks a lot bigger, like a 4 stroke

Electric and pull start is ridiculously redundant and the width of the pull to much

First off the bt electric start engine they are junk I've had two of them the first one the crank broke the second one has had two different cylinders 4 different pistons all due to broken piston wrist pin clip and bike berry has no parts for them

Yeah I got a bullet train myself paid 300 bucks for that piece of s*** it didn't even last a month I can't even go out and start mine it won't even start up cuz it's junk don't buy them you'd be better off with a regular 80cc bicycle I've never had no problems with those bikes

Really that engine is way off on CiCi's the Americans ARE ALSO way off on ANY CC engine's it's ABOUT 15 to 20 less CC's than what The Americans really think that engine REALLY is but you ARE RIGHT ABOUT China's major ON ANY event's when it comes to ANY gasoline engines a lot of experts in America REALLY are NOT REAL experts if THAT REALLY makes ANY REAL sense

What are those front forks?

People tend to think performance is just top speed . They just dont get what torque is i guess. People i know are always like i dont need to go fast. What im talking about taking off . Believe me i know how that goes .
