I would love to see us come out the end of this series with good ballpark numbers for optimal port timings! There is literally nowhere on youtube that has even attempted to put that kind of specific info out there for everybody. Of course I realize that every one is not going to be exactly the same, and different people will be using different parts, however with some baseline numbers ALOT of folks can be helped out and I think its a great idea starting from the stock outta the box like this! I look forward to seeing more, thanks!
Based off of every cylinder I have work on in the past, we will be able to give a safe universal cutting measurement that should work well on nearly any motor, without the use of a degree wheel. I'll be sure to include it early in the series.
I really appreciate your videos, I just got into the motorized bike game myself, it's been an amazing hobby, I also have a 47mm piston 40mm stroke (not a Zeda but a BFG bottom end) with a bunch of frankenparts. Funnily enough I'm about to get a new cylinder (not a G4 but should still be good with any luck) and was going to have a friend port it and it's nice to see the process going into what is needed to find timings and get a baseline for porting it. Thank you so much for everything you do. You've given a lot of great advice and it means a lot to me that you keep persevering and trying new things. If you're interested, the full setup is a Trek Mountain Sport 800, 6 spoke mag wheels (still going strong so far) w/Michelin Protek Cross tires. 11 front tooth 32 rear secured w/12.9g bolts, the engine is a BGF 80 "super racing" bottom end, basic cylinder (changing because the casting is complete potmetal, and a high compression head running a 63 jet on the "racing" carb (19mm Runtong). I'm hoping to get a felt faker frame at some point w/adjustable damping forks and see how well it rides after. Hope you have a great day, and safe travels on your break in! Looking forward to the next video!
Your top dog man. You are helping the motorized bike hobby a grip! Thank you. I love your new gas bike frame, it looks amazing. All your bikes are cool but that one by far is my fav.
That’s what motor I’ve had for I’d say atleast 500-700 miles and love it and it runs freaking great. Of course I jetted it put a pipe on it but other than that and light polish/porting it’s amazing little engine
I have 4k miles on a Kasei 1e48f 63cc powerhead , 2.2k miles on a Zanoah g430 and only problem besides very light maint was broken starter rope on kasei at 600miles and new fuel lines and filters , also dismantle and cleaned Walbro carb on Zanoah cause fuel line cracked at filter in the tank . Ive had both these engines 2 1/2 yrs , never been inside of them and whats amazing is they both run better than new . I primaraly run Echo Red Armour oil and can only get 87octane non eth fuel so i use octane booster to around 91 octane seems the sweet spot at 32 : 1 mix .all street miles I want to try these type engines but when i do i want a really hi quality outta the box engine , but china dont seem to take us seriously . Had my eyes on the new moto 85 but the cylinder has tiny fins designed for forced air and they already have wristpin trouble . Wish Japan or Taiwan would notice us as china dont give a sxxt
Perfect timing for this video.You seem to be humming right along with this series already.Thank you for taking your parts and skills in hand to show us what we could do to have a better chance at making our motors better with power,and efficiency too.
The triple 40 firestorm edition is a great motor one of these day im going to start posting videos as well for fun. Thanks for being the badass you are bro
To try and get more life out of my gas tank mounts and clutch hand lever pin. Before installing, I put some JB weld around the base of each gas tank threaded stud (sanded a bit,cleaned, added JB weld) and a little dab of JB weld on the bottom of the clutch lever pin where that flimsy aluminum washer is. I seen some people using a dab of solder. I'm not sure how much longer it'll make it last but it was only 25 cents worth JB weld.
I just bent my left handle bar up by putting to much force on it while trying to take off really hard from a stop... sometimes I’m happy stuff breaks,, it gives me an excuse to replace it with something better.
Nice vid man . Ive shyed away from these types engines but now wanna dive in if theres truly hi quality outta the box long life engine already on the scene or hopefully come out in the future cause im tired o gettin caught in the rain w friction dr
I love your videos I have a seeutek 80cc that's my daily driver for work any tips to keep her running good. Only had one spark plug go bad yet after 200 miles would love your input
Same here. I didn't have any plug go bad but I put a new in and I'm at 800 miles on mine and it is running great! I would really like to keep it that way! If you or anyone has any tips since I am learning small engines with this I would really appreciate it!
I have put around 1500 miles on my Anbull 100cc same plug. I did have to replace the fuel tank, my 3 liter tank developed a leak. Mixing gas and oil is important 32:1 to 40:1 will make your plug last longer.
@@raymondsoutherland245 thanks for the input. My plug wasn't covered in oil or junk it was just cheap Chinese made. I used the proper oil to gas mix for the brake in and after but I love how you inform people gas mixture it's very important for 2 cycles never run without oil mix.
Great content..can u please tell me what mud flaps or fenders i can get for my cranbrook..the bike hits about 35 mph top speed i only weigh about 160lbs..lol so its plenty fast enough with the motos engine kit which i think is a pk80..nice strong,grabby clutch..i just need some wheel fenders from amazon just not sure which one to get..thanks for all of the great videos! You really know your stuff man!
Although I don't recommend fenders for bikes over 30mph, I have these on two cranbrooks and they work great. Portland Design Works Sodapop MTN... www.amazon.com/dp/B003LRAVWQ?ref=ppx_pop_mob_ap_share
Hello. I have heard you talk about the speed carburetors. I just added another carburetor to my Amazon list and it says speed on it. The reason I had to order a new carburetor is so I could get the idle adjustment screw. Bike Berry is sold out. It's a common OCCURRENCE with bike Berry.."SOLD OUT"
Hey hover I had a question. Two stroke ports said “good luck with your free motor get something better”. He also said that it’s gonna take a while to catch up to me as far as testing motos. Why does he hate you? I thought you guys shared knowledge.
I think I'm his new target because I asked bicycle engines for supplying a motor to the series. Out of nowhere he started commenting on one of my videos about how I can't possibly test as much stuff as him... So I called him out on it, and he exploded!
@@LAHover man oh man hover I just want you to know that your a good dude you actually help people out. He just makes quick vids doing nothing. Keep making videos and in my opinion he’s lashing out at you for no reason.
How well you think this would run. This is a 49mm piston. And Made it a case reed engine. The numbers I got with my degree wheel is a 170 exhaust and a 140 transfer?
Could you test the bike berry deluxe expansion chamber? There really aren’t any videos confirming it is a decent pipe, or it exists at all. Could you please try it out. Thanks.
Great video, thanks! You mentioned that the carb they use has it's downfalls with the jets. Will some of the other carbs out there work to change it out, or is this engine limited to only using the carb that comes with it?
Going on 2 years of pretty steady riding with my Firestorm, and in that entire time, besides the usual stuff I tighten/check every 3rd ride, today in fact I had to tighten the Flower Nut, as the clutch was slipping quite badly whenever I'd try to popstart it, other than that it's running great!
Hey buddy I just wondering if u no I got a yd100 I have had it about 4 years I bought the phantom 85cc kit off bicycle engines I got the jug piston and needle bearing for it but the needle bearing want fit because they change the rod on the crank hole little bit to small I looked ever where for the rod or the crank do u no where I Can buy one
Interesting... I'm new to this stuff. What is the "blow-down" term (the 14 degrees)? I'm still trying to understand and amazed at how engines work. Currently using oscilloscope and pressure transducers to plot how engine pressures work (especially the 2 stroke) and their waveforms.
Sorry for the late reply. Blow down is the amount of degrees between exhaust open and transfer open. Will cover it more later, but in general the more blow down the better. As it allows more time for the exhaust gas to escape without mixing into the intake charge.
New one is on the way with an upgraded bushing. From what I was told, it sounds like they are still testing the updated motors before putting them back up. Will keep you all posted.
Although length does play a part in views and watch time, it goes much deeper than that. Here is a great video that covers video length in detail, if you are interested :) th-cam.com/video/uh2ZoxpiYm8/w-d-xo.html
Since I have only gotten into motorized bicycles a little over a year I have only been given g4 cylinders in every motor I have had since it’s the new cylinder style but I don’t like it I would rather have one of those old school closed transfer port cylinders with the crude casting it seems as if they run better from the videos I’ve seen
The older style cylinders are good, it's just hard to find a good one these day because the molds used to cast them are worn out. :( ... the last three I got had bad port castings which have caused bad timing and low performance. My Seeutek has the old style cast off a still good mold and it rips :)
Your not so much limited by the angle of the motor, as you are by the angle of the carb. At some point a steep angle will start messing with fuel delivery. Ideally you want the top and bottom motor mounts to set as flush on the frame as possible to avoid stressing the frame.
@@redneckinventions8733 It's his thing, live and let live I guess... Just be carful if you try to give him a compliment, he might take it the wrong way and explode. If you try to explain it was a compliment he will double down and make it worse.
Hey LA, I was wondering if you had some (extra/junk) parts you could spare in order to get my china doll up and runnung again? I can pay for shipping Please ...
Hey, i need some help with something. So i lost the little piece of metal that goes into the little notch the drive gear has on it. Do you know what its called by chance?
out of the box they will top out at 5,500rpm~. Porting can get them as high as 11,000rpm~, but you will need to balance the crank if you want to go higher than about 7,000rmp Will be covering this info in more detail during future videos.
@@LAHover Very cool I love that the gas tank is integrated as the frame. I do not love the price tho would you say that it is of quality compared to similar priced bikes as far as the other components?
I think he had an injury that makes it difficult to ride anymore. Now he has all this knowledge on bike motors that he can't use for him self. I don't know what the man is going through, I just hope he gets better.
