$350+, 6mm mounting instead of 8mm, Only one proprietary exhaust option & finally no piston port variant. Very hard to make that purchase when you can pay $80 for a 49mm iron bore.🤔 Did you pay for it or did the bike berry dude hook you up?
😂 I think the BikeBerry guy set him up. Ouch.....I have a 47mm china Doll that could take this motor on😎 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0RzH1eDA6lE.html
Bt100 has lots zink in casting materials made in chin lousie indina foundries. Lots zink cadmium makes it crack easy. All the metal is pot metal in bt engines. Same factories that make hone drpo (amazon brand) weedeater things blow up after 7 uses worse then China made castings lolz steel probably flung cast steel then bored out with razorblade 😂 you know for sure this was a freebie arsh kiss video😅 so huge cause all zink retains heat Lack of sleeve index point is dead give away spun casted steel sleeve. Zink makes it nice dull shinny white color though😂 oil resistant easy to clean😮 best thing this whole damn engine is fact it has 14mm pistion wrist pin lol
Good-luck with that,🙄, Alex only makes video's when someone sends him something for free,🤑, these companies sending him stuff should demand more than just one video from him.😋👍
I think this is what we have been wanting from a 100 they already had great power but they always got to hot and melted the exhaust side of the cylinder walls and piston this iron sleave and more surface area of fins and the humongous head this should last at 3/4 / wide open for as long as you want and be able to do the long distance drives a modified 80 can do like 200 300 kilometers round trip
10:05 @MotoredLife the 4 screws there match with the G2 reed valve, drill out the G2 reed valve, install an intake manifold where you screw it onto the cylinder and install it completely. Then you would have more air-fuel mixture than before, then it will displace more and the engine will turn like that theory higher with out porting- or piston changes details actually !
I actually like the 2 bolt chain tensioner because of the straight vertical adjusting slot. I just drill out 4 corner holes and make it a 6 bolt. I wrap skateboard grip tape on the frame chain stay where I clamp the tensioner and it dosen't move at all.
My bt100 has 3 piston rings the bt100.2 on the video only has two will this change the compression? Also those reed valves look amazing, engine size might be a little too hunky for a pleasant ride and a two piece jug might have compression loss if gaskets are not seated properly. All in all looks amazing hope it performs wonderfully yet I do have some concerning questions especially heat transfer to carburetor and piston performance with one less piston ring
I would like to see the bore and stroke checked to make sure the stroke is 40 mm not 37 mm also would like to see how they stuffed the case. And also would like to see what the transfer ports look like with the person at the bottom center to the transfer ports clear of the piston are does the piston block part of the port which would restrict flow into the cylinder?
I have a question, i have a bt100 v1 and as far as i know, the only mods/upgrade i can do to my engine is to change the block/cylinder head to make it v2. I didn't see any video on YT modifying this engine or even any of the shelf parts that's plug and play... So theres the question, what other mods can i do to the engine? Thanks...
btw why they don't wan't make the magneto little bit bigger and heavy and aslofo flywheel wheight get heavy to, cause they importarn for get inertia movement from that magnetto to help crankshaft rotate easily???
Can I get a good Recommendation on 2 cycle oil I'm buying a bike in the next couple of weeks and I'm trying to find the best oil to use for it. Thank you
Let's play along and say this will make 5hp. That's enough to go 60km/h (37mph). Downhill 70-80km/h. If you're going that fast on bicycle tyres & brakes (even hydraulic discs) you are a hazard to yourself and others. These things look cool to kids & convicted drunk drivers but more than a few people get killed on them.
Oh' i donth' wahnt have the! Big moulf bat i forget too' thold be'fore Open the original engine doo' First Name: Druck Probe. If everything Name: dicht 85- 95 % soo' No Name: dichtflächen Fehler. Jes after meby poriting.
excited? For another super cheap jank ass 2 stroke? nah, man. it's 4 strokes or nothin. I use these motorized bikes to make money. When they aren't broken on my porch. Which is 85% of the time. I'm done with 2 strokes.
For a newbie (myself) what engine would you recommend? Note. I'm considering for use as a paramotor? Also your recommendations on most reliable 2 stroke you have been exposed to? Expansion chambers and modifications? My thinning is that if this is your bread and butter you are going to have some experience about various different engine types and modifications? I do acknowledge your dislike for 2 strokes also, but as a paramotor application running mostly as a stationary motor most of the time? I'm considering power to weight and hope you can look past your exposure to these motors in a motorised bike application?
@@jameshatton4211 bike motors have reduction gearing to drive a bicycle wheel, not a propeller. Even if you could make it work, you definitely don't want a low quality, low reliability bike motor to go flying with, at any price.
@@vk2aafhamradio I'm new to this, and planning to do my first motorized bicycle build soon. Is there such thing as a bicycle motor that's NOT low quality? If so, 🙏please, do tell, and point me in the right direction?
