I see BMW has had a major influence on your ability to overcomplicate things for worse reliability 😂
😂😂😂
I think I've seen a few ppl use like a banjo plate to mount the tensioners on for a cleaner look but whatever works for you is all it has to be! these engine kits are always fiddly and sometimes fussy but you get a good idea what they need after the first one you do
keep up the good work bud. building is the best part of this hobby. Just a tip from my build, I re positioned the drive chain behind the bike chain and the chains didn't collide anymore for me. Be safe, bike life!
Quick tip if you're not using it already, rubber fuel grade hose and clamps. Doesn't fail as easy as plastic. Check with NAPA auto parts they sell it by the foot and its fairly cheap. Same place for clamps.
I had one of these on mine and it was just the finickiest thing I ever experienced. I finally tossed it after riding down the road at about 40 the chain on the jackshaft decided to explode
re seat the grabby guys . I love it .
That bad boy is scary but dude you are going for it .
Congratulations on the Bike
I opened your video to motivate myself to make bad decisions 😅 but now all I see is that E30 in the back 😍😭❤
The video I'm looking for about a bicycle engine that uses gears is just you are very good
If you send down the area that the Post starts sits in end clean A play a little grease in there it will pull smoothly.
The simpler the mechanism, the better.🎉
I always buy 2 of everything. Sometimes you just have to experiment.
Use a bmx chain from shaft to freewheel works 100% better that 415 chain is not made for that sprocket
good recommendation
just buy an actual motorcycle 415 it will support the 3 hp much better than any bicycle chain as no bicycle chain is made to support 3 horsepower for at least 5 minutes, i had my setup loose and the chain went up between the sprocket and spokes at 30 and i didnt had any problems xD maybe with the spokes tho anyways the same thing happened to me with those cheap motorized bike chains and it broke the chain 1 out of 2 times when it happened, sorry for the shitty english im portuguese and i havent practiced much latelly xDD

@@robertbrawley5048 damn bro thanks a lot xD
@@ez_do_102 have you seen JSARCADUURA channel on fig tree propagation. . He is Portuguese and lives lives in Portugal. . He was shy about his English and started off with caption only then he added his English narration. With apologies. . No apologies need his Portuguese accent English is very understandable. To an American listener.
First and last name please? I want to buy an insurance policy before it's to late LOL! Looks like fun build!
Actually safer than regular gas bikes it puts 2 free wheels between the motor and the rear wheel. Usually when a motor blows the rear wheel will lock up because it is direct drive after the clutch
I'm about to put an engine on mine.. but it doesn't have multiple gears on the outside and a derailer .. the gears are all in the hub.
Pretty cool
nice e30, I have a few myself lol
Ohh so a shift kit is how you get the power to the pedals can this give it a higher top speed? Do the peddles spin fast with it or can you keep them still ?
The pedals are on their own freewheel that comes with the kit so they only grab in the direction you pedal in.
Thank you
Wait so are you still able to hold the clutch in to pedal or does the clutch not work when you add this I’m confused lol. I’m only asking because the clutch is fun to use, and it’s easy to start since all you have to do is just pop it out and start the bike especially on a. Cold day
Yes you can hold the clutch in to pedal. I don't remember if you can still bump start the bike or not but I prefer the pull start. It's easier for testing things since I don't need to go anywhere to fire up the bike.
I think you need to pedal to start it, because the cassette just rathchets if you're not pedalling
Great explanation though as I didn't know anything about it either and went through a have always been good at tinkering on 2 strokes got that thing mean in the engine to really run when you change the car braiders the 1st thing and intake just like on anything for 2 stroke you put a different pipe on it that makes one heck of a difference after you get a good carb for it and it has a good intake The engine kit suck my horse I can't remember the full name Crazy Horse I don't remember but anyway that is I feel the best set up for the generic setup engine compared to that other stuff they're making now
Thanks
I think i would die if i put a shift kit on mine🤣 without disk breaks i just stick my foot in the back tire LOL
it just looks over thought but thats just me. the star thats drawn with all the rectangular lines is easier to to draw than the other one but more complicated from the looks of it lol if that makes any sense at all.i retract this statement well thought out great job
The set stew can be purchased most large hardware store
I know. They all rattle out. Hose clamps worked better
the hole in the gear is threaded for a set screw. it would stay on and you could get rid of that hose clamp
I went to war many times with the set screws. Hose clamp and woodruff key turned out to be the most reliable solution.
Literally had a e30 also working on bike in the background
This may seem like a dumb question but why do people put on shift kits? Does it go faster?
They can go faster. I like being able to take off from a stop in first gear without really pedaling, climb hills easier, and cruise at a lower RPM.
I have the 80cc on the same bike and its great
80cc is really just 66cc
@@nostalgiaholic4874 Depends on if he is talking about a 66cc or 79cc
your head gasket should be turned 90 degrees to let air go through the fins. great bike though!
Oh yeah 😎. "Jack Shaft"?
Dude you got the engine in their sideways! You got that all cockeyed the engine needs to be straight readjust clamps motor mounts! The drive chain are on a bind!
That's a perfect example of how to complicate the hell out of something that's very straightforward and what's with the parts of washers the hose clamp and everything else when that stuff let's go and all those bits and pieces are binding up against each other and like your whole Driveline just seizes up in one instant you're going to be one hurting unit take all that stuff off and save your life
If I die I'll be sure to haunt you and let you know you were right.
Chill and leave us to our own builds. If it works, it works. Not your problem if it breaks
how long does the chain last if you are hard or soft on the throttle?
Haven't broken one yet. The engine isn't powerful enough to hurt the chain.
@@kelso840 alright thanks for the info!
Any reason everyone installs their head sideways? The cooling fins should be with the direction of the wind so you get more air passing through them. Sideways I can’t see you get any, it would hit the fin and turbulence would make it go haywire and you wouldn’t have as efficient cooling.
Only reason I can think is it's a 50/50 chance if you don't know any better, which I didn't at the time. It doesn't cause immediate or obvious harm so I'm still running it sideways a couple summers later.
@@kelso840 I thought maybe they’re coming preinstalled like that from some suppliers or something.
@@kelso840 should swap it around fam also give you a chance to clean your piston and head up im sure you have carbon in it
Hey! I got the same bike frame as you! I’m considering a jack shaft kit for my build, you think I should install one? I plan on buying a Chinese one.
Don't buy the Chinese one. I thought I could figure it out and failed miserably. Get the Sick Bike Parts Kit and tensioner.
It's only worth it if you like tinkering, want to cruise at a lower RPM, and not be as reliant on pedal power when taking off from a stop.
I gained nothing in terms of top speed.
@@kelso840 I love tinkering. Hell, I practically take my engine apart after every ride lol. I’m starting to reconsider as the price is high and I’m better off stock. Have any other suggestions? Thanks.
@@Farmtractor I'm considering port matching my intake and exhaust to get a bit more top end power. You're right about cost. I have way too much money in that bike.
It's "reliable" enough that I don't want to make too many changes and spend more time fiddling than riding.
You should get a pull starter if you don't have one already. People say they're junk but I tightened the screws on mine and use it tenderly and it works great.
@@kelso840 it will hit my crank arms though.. I would get one. I also plan on porting my build.
@@Farmtractor ahhh. Right. The shift kit comes with different crank arms that give some extra clearance. Good catch.
I had bought one of sick bike parts kit and ended up throwing it away cause it didn't work right on the motor and bike I had at the time.
Your cylinder head is mounted in the wrong way
You caught me. I'll fix it if I ever take the head off.
Its not wrong if it works! Bike building 101
@@aggro0o886 aircooling flow must be disturbed that way
I see this all the time in the “community”
Love that bmw 🦾
How fast does it go
Your gears are right. 17T on the left side, 10T on the right.
Da hora
it looks like when the clutch kicks in , you're involuntarily force to pedal is run????????????
Can the jackshaft kit work on one piece crank
Don't think so.
@@kelso840 oh
how fast is that
Having a tensioner on the drive side of chain is asking for trouble
Do the pedals rotate the hole time
Nope
@@kelso840 god can you imagine lol
Do you still have to pedal
Not really. It's still helpful to pedal from a dead stop but the engine can move the bike from zero if you're in first gear.
Why did you even put that pull starter kit on it? Cause when you put that kit on it, it becomes a kick started motor on a bicycle. I'd like to like to say is a MMB motorized mountain bike.
Unless we're in a court of law I don't see it as a fundamentally transformative modification.
Forgive my noobish ignorance but why not skip the entire jackshaft kit bs and just use the bottom bracket/ crank as the jackshaft by putting large drive sprocket on left side, to just go straight down from motor sprocket and leaving the stock right crank in tact?'
In other words, just like stock engine drive setup except output sprocket moved forward from left side of rear wheel to left pedal. Would seem a lot lighter and less complicated other than having to replace left crank arm, (which you're already doing to the right side otherwise). What restrictions are there??
That's an interesting thought. You would probably still want this crank because it has an additional freewheel built into it so your pedals aren't directly connected to the motor.
I bet your could work if you found a rear wheel that had the gears on the left side.
@@kelso840
no, don't need rear wheel with gears on left side. it would transfer power through the crank to the right side as it is. just like the stock situation does putting the sprocket on the left side of rear wheel, you can still pedal shift. but instead of rear wheel, put it on left side of crank somehow.
@@Thrashaero I think I see what you're saying now.
You would need to come up with a freewheeling drive gear for the left crank arm so you aren't forced to pedal at the motor's RPM but I think your idea could work.
@@kelso840 Right just take the right side freewheel crank and put it on left. probably needs reversed direction of pawls ofc and maybe different width dimensions but that's all that's needed, not extra sprockets, axle, bearings, and flanges to hold what's essentially already on the bike (bottom bracket)
@@Thrashaero totally stealing this idea!!! Gonna see what I can come up with using a freewheel for both sides...but as of now, all I can come up with is the sbp kit has the freewheel on the right side of the crank spinning around the crank to keep from having to pedal. I imagine it could be done but would have to do something about where to put my feet and how to start the engine.
I haven't used any of the motorized bikes I have in years but I have many different types of styles of bicycle all the same engine I chose from China's wondfrom china there's one that's I feel 1 of the better ones but anyway the speed is what hurts the stock chain I was eating up chain left and right have a friend that builds bicycles and got bills bicycles and got me a bag of master links but they break because of the tension on 1 of my bikes ago over 55 . But then you're burning up the barrens and the wheels of the tires cause they're not made for that kind of speed
Just use a impact power drill to start it
yeah bro thats a cool idea much better to carry a fucking portable drill then just have a pull start everywhere ( fucking dumbass Bommers probably )
what size engine is on it?
It's a standard China kit. 66 or 80cc.
@@kelso840 so you got the larger motor,, here in west virginia we have to keep the 50cc to ride on the main roads and be legal , 50cc and under no license required. larger you have to have a motor cycle license.
SickBikeParts is now inactive. RIP
Dude your piston head is on wrong. The fins are soposed to be parallel with the wind. The wind flows through the fins and cools your engine
This is known. I'll change it if I ever take the head off again.
why don't you make a chain guard
Haven't needed one yet.
That back wheel ain't gonna last I went thru eight of them
Aye, I've gone through a back wheel after my chain tensioner was bent into my spokes and again the other day, front brakes sheared the rim and locked up the front wheel, certainly didn't tickle when I went over the bars at 50kmh
Why are your handlebars catywampus
Everything about the bike is catywampus. Adds character.
Je veux voir ton pédalié quand ton moteur tourne..pcq si ton pédalié tourne tout le temp sa donne complètement rien..apport ce blessé ses que ton pédalié faudrais qu il face du sur place quand le moteur tourne..
Shifter kit puts too much strain on the thin pedal chain
People think a fair price constitutes false advertising
Seeing this monstrosity, if I ever buy one of these kits, it's gonna go with a 3 or 5 gears within the rear hub, so it's not these tiny little chain that takes all the torque.
Ouais mais..ton pédalié doi tourné quand ton moteur tourne..??quoi tu te lève les pied dans air.?
Looks dangerous, don't ride near road, that'll lock up when it breaks soon !!
Before and after top speed
About the same. The engine is running rich and starts bogging up top.
My masterlink keeps falling off
Make sure it’s not bent in any way, and is going in the direction of the motor spinning. If it’s backwards it will come off every time
Please sorry but you need a camera can't see anything that you are recorded just a blurr.
Ganhou mais um escrito se pode retribuir Tmj 👍👍👍
your head is on sideways turn it 90 degrees
OMG will it be ok?!?
@@kelso840 OMG your so cleverly sarcastic
@@JERRY-ix2mn My apologies, Mr. Dingleberry.
@@kelso840 all is well
I saw some pictures where they put the piston in backwards and head on backwards
how about BMW? :)
More BMW videos on my channel.
You didn't shift. Damn you.
There's a 1, 2, 3,4 shift @9:41
... Oh. Damn, that was subtle.
@@bowlsnapper6206 the click shifter is where it's at.
Can that regular bike chain and rear gearing handle the power for long?
@@bowlsnapper6206 hasn't broken yet. I don't ride a whole lot but it's got a good two summers worth of riding on it.
Bro no what are ya doin, you got the head on the wrong way
OMG!! Is that why there's blue smoke?!?
Bro... Blue smoke, yea you gotta turn that head so the fins are facing the same direction as the bike
please get a new exauhst
Why have a shift kit if your only gonna go 15 mph ????????
Get rid of that crap pull starter .
Buy two leg kick stand.
Use pedal to kick start bike.
Class dismissed.
How fast does it go
