My 139qmb 50cc died on me. After taking engine apart, bearing on variator side failed BIG time. Both sides of braces holding bearings came apart, bend the timing chaing and pieces of bearing brace fall bottom of the engine. Today ordered new crankshaft with bearings, oil seals, full gasket set, timing chaing set inc guides and tensioner, valve oil seals. While waiting for the parts will wash, clean and lap the valves. Thanks for the video.
Personally, I question the quality of Glixal parts. My wife's 72cc big bore kit melted in the same fashion, with a big hole in the middle of the piston. Nice video.
Thank you.. Glial metal parts sucks ostrich eggs. That little orange cooling fan is hot garbage also, but I rarely have a problem with their plastic parts. I'm using the regulator, and maybe one or two more plastic parts that haven't completely failed on me. But I'll be darned if I'm going to put their A9 cam in my engine.
@@kachiskid hey kachi , so I have this 150 gator e3 n there's a white smoke coming out of valve cover breather is any way I can fix it ? I got my scooter started after bought new battery but had to shut it off cause of the smoke
@@kachiskid me too just need to buy right tools for it and I bought this scooter from this dude for 550. He said that belt was broken which is wasn't there's a oil spill under the seat bucket. When my guy took the dip stick out there's no oil smh the other day I bought 15 w40 then I change the oil there's a black chunks coming out . I have no clue what he did to the scooter and I just bought new spark plugs today I just gotta fully charge the battery and see what's going to happen . Oh hey the exhaust doesn't have a bracket around it so I have no idea tbh
@@merjimjimenez1361 Dang, sounds like you have a project on your hands. Black chunks? I wonder what that piston looks like. You might want to crack the whole case open, just doesn't sound good. How long was the bike sitting for, how many miles?
@@kachiskid you're gonna laugh. So I put on my second no name belt and almost 200 miles later I hear a pop... scooter dies...so I assume the belt. I let it sit for a week. I just tore it apart and it turns out I dropped a valve. My head and piston are more melted than yours and the valve is one with the piston now, but hey the good news is my cvt belt is still good.
When you put new cyl and head on make sure you clean out crank case pull oil screen and spray carburetor cleaner inside till it is just carb cleaner and no oil or metal let it sit open for a day and all cleaner will evaporate in that day .if you leave metal in it the bearings will be destroyed
Be careful with compressed air there is a bb above the screen oil strainer if you blow it out you will not build oil pressure obviously you do what you want but i would not use compressed air in there you could also push metal fragments into the berings
That that happened to me with the little one the 50cc when I put the big bore kit the last three thousand miles it got hot on top of the piston same thing exactly so I order another big bore put it together and I'm trying to sell it.
I have question how do you tune your valves? Some people says .0004 for both intake and exhaust.. some people says 0.05 intake 0.08 exhaust? Which one is right? And also is .0004 equals 0.04? is that same thing?
Nope, 0.004 and 0.04 are NOT the same, big difference. It depends if you have a 50cc or 150cc, but 0.004 is the size of the valve adjustment tool, that you'll use to adjust the tappet. I think I set my last adjustment to .004 and .005 (exhaust).
Kachi, hit me up I'm about ready to post an sspg big bore I put on my wifes scoot. I used their head it's a ban jing better quality and surprisingly affordable. All is not lost..you'll get her going.
Can't wait to see it! When are we gonna get some riding video's out of you? Have you been putting miles on her this season. We must enjoy the fruits of our labors. Hope will be back on the streets soon. Gotta make a run to Florida but when I get back...it's on like Donkey Kong!
Ive got my scooter gy6 150cc with no changes or modified. Can I install NCY decompression tube item on my scooter??? Or I need to modify something aditional. Please help. Thank You!
Mi gy6 150cc la compré nueva este año tiene 7 meses de antigüedad y 897 millas le hice el cambio de aceite y de transmisión pasadas las 600 millas, le monte Mobil 1 racing 4t 10/40 y Quicksilver performance 90...ahora mismo me está tirando mucho aceite de motor y yo creo tal vez sea por el ceite que le e puesto que igual es muy fino? Aunque yo creo más bién qué va a ser el retén del cigüeñal que aunque elotor es tipo honda todo lo demas... stator, Carburador, juntas. Retenes...es chino así que la calidad muy pobre...usted que cree pueda ser?
Thanks for asking brother, very slow motion...just got back from vaca and that costs to much always. I have to wait until Thursday to even think about affording the new engine. Also assembling the pocket bike, the buyer is waiting... I got 40+ subs when I was away so that's good!
Kachi's Kid, Nice buddy. Well welcome back from whatever wonderland you went too. Lol. And you'll get the funds to revive Hope soon enough. 40+ subs in a matter of a couple weeks. Damn that's awesome. Congrats bro. I have one or two subs on my channel. But only 3 BS vids on mine 😒 . But ill be putting more up once I come up with a good idea. Libby is about 90% done. All I have left before I show her off to the world. Is to redo my new exhaust pipe brackets. I have to use the stock one for now. Not bad just no chrome but damn she rumbles real nice. But everything else I put on her looks awesome. It would be very cool if you would be alright with me tagging you in that video. Might just help me with one or two more subs. LMAO. Anyway I'm going to get back at her. TTYL Bro
Really looking forward to introducing Libby your subs and views will increase BIG TIME! Give us a really good review, film in landscape...please...lol.
That wasn't your original head right. Also you did mention when you installed BBK that you put one part in upside down and it did some damage. Did you ever get a chance to put the original head back on before valve head destroyed your piston and i imagine the cylinder too. Also the new head you put came with vavles or did you put your existing valves on the new head. Anyway good luck new bbk. I will be waiting to see that mod.
Great job Glen, you my friend were paying attention....Ok so my original 61mm head that I put in on the big bore install video was destroyed because I put the chain tensioner guide in there upside down. A chip of it broke over and damaged that head. When I ordered a replacement (61mm) I installed it but as I was tightening the exhaust the bolt snapped. I attempted to drill it out and made it worse. On to the next 61mm but they were out of stock, so I made a mistake (in my mind) and went with the 57.4mm. Doing this knowing that I already had bought the 61mm one on Amazon from eHaze. www.amazon.com/gp/product/B00ORYSWCI/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 It was originally priced at $70, but I got it for $30. Set that aside with an A9 cam, and was planning on making a video on the upgrade to see a power difference. Never got the chance to with all the weather change, tuning problems, and now this.... all heads I buy have valves pre-installed. My cylinder is in perfect condition.
@@kachiskid Ty, that cleared up a lot for me. But still a little confused. The original head is 61mm ? the glixial you link is also 61mm and the ehaze is 61mm, where did the 57.4mm come from ? Next its the ehaze one that you set aside with the a9 cam right ? So you have a new head already the ehaze, you have the cam, your gonna reuse the bbk cylinder and just get new piston and rings ?. One comment omfg 1 cylinder, 3 heads, new piston and rings LMFAO I swear i aint laughing at, its just good to know I aint alone lol. Also, cranks and connecting rods we know are really solid and compared to what it would take to crack a valve and piston I imagine they are fine, but I guess it would be wise to give those a good looking over and it just know hit when you say you are glad you didnt go with the forged piston, because if the piston didnt give way where might that energy from the collision (valve head hitting the piston head) have gone. Also on re-reading some of the comments, it was the glixial head that was 57.4 ? And if so, how can you really trash its quality if it was the wrong size ?
I didn't make a video about putting on the 57.4. I am going to strip the piston down of all rings and keep the cylinder, but I am getting a whole new cylinder with piston installed from NCY for $115, and install the ehaze on top. Yes, I will be separating the crank case to take a look but I had no metal shavings or any loose parts, all parts that broke are accounted for. Good question on the forged steel but who knows where that energy would have gone, most likely blew the head off. I know I would have been out of $50 more because I would have replaced that piston anyway. People run the smaller head with no problems, I just don't like it, she even felt better with the short time I had the 61mm on there. No matter the size, that valve shouldn't have broken off. I watched trashing Glixal, I just want to give another company a chance to make me happy. I couldn't pass up that deal I got on the ehaze head.
@@kachiskid Thanks, ok back to square if/when you have some time. Technically if i wanted to do bbk. All I really have to have is the new cylinder with piston and rings ? I can use existing head and all its components. New gaskets of course, is this right ?
Im having problems with my bike as well bro. After the rpm gauge hits 6 it'll bogg down a lot and idk what to do at this point. I just got a new carb, full pump and sparkplug and coil. Do anyone have any idea's?
Sorry to hear that bro. What size carb. are you running? When you sit on the seat you are free of fuel line and vacuum lines right? Are you running a pod filter or under seat air filter? I would check for a small leak in the manifold, or any vac. lines. to start. Also pull your spark plug, what does it look like, rich on lean? The main Jet is which controls the flow of fuel at that speed, might be to small.
@@kachiskid its a 26mm carb i believe im free of the lines but will take another look at it. How would i recognize if my sparkplug is running to rich or lean?
