I want to upgrade the carb on my 85cc but don’t know how to set the carb

[@BraydenAtyeo]

​@@danajettTake it off and look in the inside and twist the throttle to see the movement inside and redo throttle on the new carb and make it the same movement you seen in the old one you can take pics and videos of it to to help you and watch videos on how to set it up aswell so you have a good idea to put it together properly and the racing carbs with the honeycomb filter if you take that of it will give the bike 7 to 15 kmh of more speed but people don't recommend because dirt can get in the carburetor your welcome.

[@I.M.SofaKingdom]

I hope your build went well. I just discovered this guy, and I'm impressed with the way his bike just screams! This guy knows his shit! I'm thinking of putting a Phantom 85 on a chopper frame. I just did a yd 100 on a Cranbrook, and it runs crappy. Constant 4 stroking, and so far nothing is working. I moved the needle, changed the carburetor. Nothing. Can't get the power jet to kick in. Top end speed is 28 mph. My first yd 100 got me 35 mph out of the box! I'm thinking about going back and taking off the head and checking the insides. I know I should have done that first, but I never really had to before. Again, good luck with that Phantom. I heard it's a very powerful motor and can get a wheelie from the get go. Sounds like fun!

That's scary fast next to moving cars and right next to the curb. Especially when the ground is wet. I don't trust people in cars as they seem very impatient to be behind someone on a bike. They do the same thing to people in motorcycles. Stay safe brother 😊

[@trentbikes]

haha yea

[@peterjohn3180]

Try using minimoto exhaust expansion chambers. If you can weld you can pie cut etc for right shape to fit. When you raise exhaust port you lower compression ratio as the distance between the top of port and head is less. I raise mine about 2-3 mm! I lower inlet by the same! What is the cylinder you started with? Coated bore and enclosed transfers! All I can find is open transfer slots or cylinder with liner that makes lips.

Hi in have na yd100 and How i do to fix the problem of the engine jumping, jerking at low speeds?

[@1RickSanchez]

I have noticed in your newer videos, you are not running that Tillotson carb. What are the downsides to that carb in this application? Lean midrange? I Have seen good things about the Nibbi. What do you think. My riding style is similar to yours. I also noticed, you were not using your RMH pipe for your newer build. Why? I already have a couple of their pipes for my current/future builds. I am mostly wondering what to look out for when I use these parts. Thanks for your time!

[@trentbikes]

Because it was an old and clapped out pipe. Decided to buy a stage6 streetrace pipe for better welds and thicker metal for a cheaper price. And the carbs, for whatever reason I'm having issues with them now, harder to start, idling very high and going from 6 to 7k rpm up and down in a cycle for whatever reason then dying. Not feeding enough fuel at WOT no matter how much I back out the H screw. Once I go back to my VM20 carb, those issues are gone. It was making me really angry.

[@1RickSanchez]

@@trentbikes THANKS! I have not run my RMH pipes yet but have noticed some questionables, obviously optimizing everything I can. As far as the carb goes, I wonder if the vac sensing circuit has a leak. It is way close to inside and outside air. Thank you for your response,

Thats insane (3 minute mark) how fast that kicked in....i top out at 29mph and im not sure honestly whats really holding me back.... I have a cheap $65 ld80 motor...stock nt carb...i do have some type of expansion chamber exhaust...it has a VERY small expansion chamber on it but its a long pipe...i got an mz65 on the way im curious what that will do....id be happy at 35 maybe 40.... The motor is advertised to go 24mph so maybe it's got a smaller rod height or rod stroke whstever they call it...maybe you can only get this cheap motor to go so fast i dint know

[@beppisdoggo8213]

i would recommend using a pulse pump like a lawn mower to solve the delivery issue keep up the good work

[@trentbikes]

a pumper carb already has a pulse pump built in

[@bigcconservativeguy2534]

@@trentbikes No you are incorrect. You are conflating the diaphragm design that works similar to a weak pump in response to a vacuum pulse but it definitely does not have a true fuel pump built in. You need to add an external mechanical fuel pump if you are going to run a diaphragm carb or you will suffer perpetual delivery issues as the diaphragm is in no way strong enough to work as an actual fuel pump!

[@tauncfester3022]

@@bigcconservativeguy2534 Guess I've been doing it all wrong all along then. My weedeater engined, friction drive bike engine has been happily delivering fuel to the carb from a fuel tank set underneath it for 6 years now. Guess I'm going to have to find a "mechanical" pump... Oh that's right, pumping gasoline using vacuum pulses is what my old 2 cycle SAAB's did for 15 years of use, and most backpack leaf blowers and a lot of garden implement engines "pump gasoline" just fine using these little vacuum to mechanical pumps.

[@peterjohn3180]

On vintage bikes they have cranks like this note the crank pin is far from the edge/ outside unlike modern bikes? Loads of space around the road, you can machine crank was smaller and fit stuffers in case to raise cash compression or make a shaped stuffer that clears the rod. Old Villiers 210 and bsa Bantam racers swore by it. Also fill any balance holes with resin. Btw how did you get the pulse signal for the pumper cars? I was going to buy that exact one but seller said it wasn't adjustable!

[@trentbikes]

crankcase pressure as I said in the video.

[@RayleneCawood]

Use a pneumatic dremel that spins at ~30 000 rpm to get smooth cuts: The low rpm electric dremel catches and hooks making it jump around and difficult to control. Thx to it's higher rpms the pneumatic dremel doesn't do that. It cuts smooth. Also flap wheels work way better than cutting tools on the exhaust. Use a bench grinder to size and shape them to suit. You have to make your own small ones for the transfer ports. Smooth to 500 grit or higher. (That's where skin friction drops off) Do NOT underestimate the power of a proper Bell Mouth (Velocity Stack) on the intake. WITH a properly tuned length intake tract. Try for ram air (into the wind) but be aware that the float breather then also needs ram air and tiny bell mouth. Glass lengthwise; carbon widthwise reed valves. Stuffing the crankcase. Especially with all those balance holes. (Requires more calculation) Don't underestimate aero either. Even a small but proper aero front fairing makes a big difference. NB that the top of your wheels are moving forward at 2X the speed of the bike, Drag goes up by speed squared... So aero mudguards over the top 3rd of the wheel help more than most realise.

[@trentbikes]

@@DJb-ill219 Idk about bbr, I think they're fine? I would feel safer with actual sealed ball bearings, because with just balls in the hub and axle, you do have to re-tighten every once in a while, you are also tightening the balls against a race that is also a wall inside the hub. Usually you don't want to tighten it too much, nor loosen it too much, just a little bit tight while still being able to turn the axle over, without any play. Gemini wheels are $400 a set, thick and big aluminum hubs, uses actual sealed ball bearings, and looks great overall. Or buy a set for $230 from a wheelbuilder, that I know, join my discord server and you'll find him, it's Mitchell's BikeWorks. (Note I haven't bought a set from him, nor do I know anyone who uses his set, but from what he's been saying in the dms, they seem like they will last a very long time)

@@X1GenKaneShiroX It would be upgrading the valve springs, rockers, cam, maybe porting the ports. I can't help you with that. Idk what 4 stroke you have either, and there probably isnt any aftermarket parts for things like that

[@mybikes1970]

Was it really that slow in stock form?

[@trentbikes]

Yeah somewhat. 35 to 40mph. It was during break in and also tuning, it probably would've hit 45 maybe 50 if it was broken in more. Regardless it wasn't that powerful and had weak acceleration

[@mybikes1970]

@@trentbikes thanks for" the real world test" on that motor. Seems like everyone claims 50+ right out of the box lol 👍🏾😁

[@KB_Joys]

Are you using a phone app to test head temperature?

[@Lebron2ez]

what engine are you using?

[@trentbikes]

I said avenger 85 in the video.

[@Nojusk17]

Is the banana exhaust really bad or is it just better than the stock one? Really good videos btw 💪🏼

[@trentbikes]

It is better, but you're better off with the mz65 clones as i imagine it will do way better for the price.

Did you say the squish band in your smolik head was flat?

[@trentbikes]

[@KB_Joys]
