Just a brief understanding of what the proper intake system should be like on a motorized bike engine versus setups that will cause problems and inhibit power.

Three hills that I have used for testing my bikes on over the years. most of my china girl engines couldn't tackle any of these hills without pedal assist. This engine climbs these hills like it is nothing. Definitely impressed me today.

Nice
You shaved on the sides of the key not the top of the key that way you have clearance left to write an equal on either side you saying left to right of the key
Always enjoy seeing engineering and manufacturing variations in things
Oh geez did he say he never had a pd24j gy6 carburetor but he is showing us how to do what look at it.😂😂.just kidding Franky
Not original buy it anywhere
I was about to pull my whole engine apart I was searching for videos for hours it is currently 11:37 pm and I’ve been trying to figure out why these things fell out thank god I didn’t break anything😭😭😭
My temp gauge came with the ring that goes around the spark plug but then there's a yellow wire I'm not sure where it goes? Can u give me some suggestions please, need help!
Yellow wire for Tachometer
no non ha solenode, ha una PTC che scalda un polmone di gas, e spinge per chiudere insomma una soluzione un po ambigua, quando lo accendi impierga un minuto per chiudere, poi consuma sempre corrente per tenere chiuso, a freddo ha un picco di corrente di piu di 1 ampere poi a caldo cala
The buck bar isn't carbide it's probably 4140 HT.
wHO SAID ITS CARBIDE.CARBIDE CUTS METAL.
How was your mid-range? I heard on these diaphragm carbs its difficult to tune for it or is non-existent Also, which Tilly carb is this?
I felt like the mid range was great. it pulled consistently from bottom to top. the pipes hit will change where the midrange dip is going into powerband. they feel just like any other carb though. way easier to tune on the fly. you just pull over, adjust while still running then keep going. this i believe is a walbro carb for like a ms360 saw i think? ill double check
@@wtmotobikes8838 I've heard various things such as mid-range being poor due to the application they're designed for where chainsaws it's usually idle, low or wide open. Here is a Tillotson HS-274 that I fabbed to work on a 372xp big bore cylinder. Did you need to mess with drilling out the jets in the carb or did it all work out well? ua-cam.com/channels/7RXesTK6t8M9d4mBUwdoNA.htmlcommunity?lb=UgkxdSqD390D-PGPY9R_TKkH6dohN21Ww2wV
How exactly do you fix it in the same spot so that it doesn't move while running
i locked the magnet in place by pinching it between two washers.
No castor based oil on the shelf? I read the castor based oil offers really good protection for accidental overheating situations or hot running air cooled 2 strokes. Since the castor oil actually gets thicker & coats more. The hotter it gets, instead of getting thinner or completely burning 🔥 away causing a no oil- metal to metal wear situation. Like non castor based oils will once they reach a certain temp. Many dirt bike riders say they use cheaper non castor in their water cooled bikes & the castor in their air cooled bikes for protection. Apparently the downside of castor is it gums up the engine quicker. Needing cleaned more & the price. But on a little engine that's easy to take apart. It shouldn't be a big deal. Some oils are a mix of castor & synthetic. I'm gonna buy some for summer. I think anyone that has a Phantom85 prone to overheating should probably invest $25 in a cylinder head temp gauge &/or use a castor oil. Apparently the Avenger 85 with a stock head likes to get really hot really fast. That's enough of the long winded comments for now.
I actually have a gallon of klots super techniplate not in the video lol. It’s 20% castor. And your 100% accurate, it does an excellent job of lubricating and not burning off. It’s downfall is it will leave a thick carbon buildup that is a pain to remove from the engine components vs the typical carbon buildup that we see in synthetic oils burning in these engines.
Isn't Benol a castor based oil?
Thank you brother
Your welcome man. Glad it helps
Your welcome brother
Best vid on clutch adjustment I’ve seen
Thank you man I appreciate the comment
Simplifies a lot of questions. Thank you.
Your welcome man. I appreciate the comment
Thanks for tutorial
Those are the best carbs I think...IV been running the phbg19mm for 5yrs now...I put it on all my engine and it makes a huge difference in power...
Are these frames the best choice for road racing? They are very long.
There’s a shorter tank frame that works decently too. I prefer this frame over the other one. Hard to get the steering castor geometry perfect tho.
I remember the Race, was this your Stroked 49mm 👽👍 🚴💥☁️☁️☁️
Yeah this was my stroker 49mm. That race weekend I had a lot of problems lol. Yeah
Great job bro bike sounds great thanks for sharing it
Great job bud. That china doll you have rips!!
Thanks man! This currently engine build was a bit experimental lol. I had the intake held on with a hose clamp lol.
@@wtmotobikes8838 Do you have any pics or vids of this build? Would be cool to see.
I’ll have to make a video specifically on the build. I’m sure many would like to see the interesting works.
@@wtmotobikes8838 I'm new to the hobby. About three yrs...tried to touch 50MPH with a 47mm china doll. I was one mph shy😄 No cigar.
@@jmrides777 nice man. Iv been toying with these since around 2008. I didn’t break 50 mph until like 2019 I think lol. Didn’t try before then either, they were just transportation back then.
I starter to Watch your vidéos I like a lot. I am getting a mountain bike this week end for a project of a two Stroke engine kit on Amazon. Do you think i could have a little fun with one of em?
Yes. Any engine for a bicycle is fun, just know they break easily and will need repairs often. Sometimes you get lucky and have one with minimal repairs for a long time
@@wtmotobikes8838 what would be the possible parts to break you would say?
100 cc 2 Stroke is good??
@@user-pt4xk5kv7e I haven’t run one yet to know if they are good. I should probably do a review
What a ending..
Pretty much a no edit clip I had. I need to make more videos for UA-cam. It’s been quite a while.
Ever hear of a fuel filter
I hate how all those clone pipes dont have a good top end to them
They’re not designed well. It’s basically a muffler with a balloon attached to it. Doesn’t actually reverberate a harmonic wave to actually harness any gains
@@wtmotobikes8838 exactly
I make chinadoll intakes for those. The bigger Tilly.
What’s the carb called? This one was a 20mm Venturi and it ran great. It was small enough that a mostly stock engine ports wise could run and have decent power. I actually raced in California on that exact carb setup and it won me a race lol.
@@wtmotobikes8838 tillotson. 24mm Venturi if I could post a picture here I would lol.
Head temp 309F ........What's the hottest you'll let the head temp. get before shutting off to cool down?
Honest 309 isn’t all that hot yet for a air cooled engine. 350 is hot, 375 is probably starting to be red zone. Iv had race engines stay in the 330-390 range an entire day tho. Depends on if you have the clearance for piston swell and if your rings are gapped enough as well. Not enough ring gap and to much heat will hot seize or eat your cylinder.
Always liked the sound on them carbs, bike was ready to Gooo 😂👽👍
she decided it was enough revving lol
Oh my God I don’t know where to fucking get this at the store dude
I just brought the 49mm iron sleeve and putting the grinder to work.
Awesome man. Cover yourself up, those metal grinding shavings are the worth slivers you’ll ever have
Thanks for the information. That's everything I needed to know
I hope you doing well man this is jayden from sweet home oregon the guy you help me out with my bike i build a new bike that fast and building 2 bike at the moment get a good shop now at my new house
You made good videos, we wish you would make more again, hell what people think 👽👍🏻
Iv been thinking about it man. I miss building them that’s for sure.
It probably ran backwards
Great vid! Question have you ran this Athena cylinder with a 40mm stroke with a 10mm spacer, or a 38mm stroke with a 6mm spacer? With the 40mm stroke my exhaust blow down percentage is 26% which seems high with the china bottom end. Also, I calculated a 21% blow down with the 38mm stroke which seems to be in a better range.
close your eyes and imagine Kermit the frog.
I run a out of the box ld90(similar to a g4 with 1mm bigger bore) running reed valve and i enjoy it quite a bit
He said the retard side 😂
Damn that thing is quick. Really nice ride you got bro. Good video.
Thank you man, I appreciate the comment.
I can't get my engine started ( bad CDI box) can the CDI box be substituted
It's me Sophia I love you videos
Great idea, thanks!
All engines run perfectly fine out the box, ya you can port, bore, put a case reed, upgrade it, but some things are just unnecessary. Still cool to experiment.
I haven’t done mine yet..but it’s gonna be necessary. I’ve installed an expansion chamber, and it’s struggling at the top end ,to break through that 4 cycling. I’ve been watching a LOT of videos on this.. yes you’re right,the damn things run really good right out of the box. Especially after break-in…so crazy
@@shawnstone4949 Right! Agreed. Keep on riding fellow bike builder. Love seeing people get into the Motorized Bicycle mindset!
My next motorized bike is 💯 gonna be full suspension. It doesn't need to be locking suspension. A low midgrade fork & rear shock makes a huge improvement over an electric or motorized hard tail.
J.w im having issues with my Ld100 portrd with a 3rd transfer,no window piston needed because of 3rd transfer.. running a oz reed wit nt carb but idles to the moon and 4 strokes and just runs like doo doo nowi Kno i need a better carb maybe a vm18 but shoul i go with a g2 reed instead of oz?
It sounds to me like you have an air leak which is causing the high idle. And your main jet might be to bit causing the 4 stroking.
@@wtmotobikes8838 I took the air filter off which helped it's not 4 stroking but I have a bad air leak om assuming it's where the oz reed bolts on to cylinder
Purchased a new one today from Amazon and was missing fuel /air flow screw will it run ok with out it ?
I have a question about a 50cc cylinder. I just recently ruined my 47mm engine and had to use this 40mm one. The new cylinder came with no open transports so I opened them up like my 47mm cylinder was. Was this a bad thing to do. was wondering because I cannot get the engine to run
How'd that black CYL run with that very wide 3rd intake port & wide boost port? Most people only make em about half as wide as the intake port.
