Some of you people are absolute assclowns. You’re acting like it’s open heart surgery! It’s a damn go kart, and it’s his! If he wants to pour hot tar in the crankcase it’s his right! Never seen so many professional engine builders on a damn go kart RU-vid channel. He spit a head, cam and a piston in that cart in half an hour and will probably run it for 3 more year. Jeez. I think he did just fine.

@ProbeGT2 5 лет назад

You are right, but given the fact that these videos are shot as tutorials, Some precaution about the dirt would have been more professionnal. But yes, he can do whatever he wants.

@SportbikerNZ 3 года назад

Internet experts, aka mechanically inept couch potatoes. Amazing how often you see them in karting channel comments with various tarded advice which a sensible person wouldn't touch with a bargepoll.

@andrewhammes1183 3 года назад

This video is well done. Precautions about dirt are a little overboard. That should be learned as a prerequisite for any engine building. How far do you want him to go? Explain the MSDS of oil, gasket sealer, and gas? Explain all pinch point dangers? Make sure you have hearing protection when your air compressor kicks on? There are some things that should be expected when you are tackling something as precise engine Assembly. There are plenty of other videos on those subjects as well

@RedBeardsGarage 5 лет назад

A couple of things for the people that are whining. 1 The oil was changed right before the meet up and went through about 3 quarts in one day from burning oil. 2 I didn't clean the engine before tearing it down and it runs perfectly fine after. 3 the dowels for the rockers were in the rockers when installed.

@tylergriffin8299 5 лет назад

Red Beard's Garage you can rebuild the top end without removing the swing arm. Remove the seat . That is how I did my carter gy6 kart.

Standard A-block gy6s can be bored and stroked to 212cc along with having 4 valve heads. B-block gy6s can be bored and stroked to 240cc along with 4 valve heads. Theres also DOHC 4 valve heads. Theres now custom machined gy6 blocks that are pushing around 350cc. Theres also water cooled cylinder kits available.

Nice job, Red! I love watching you build engines, or just about anything. Not much excuse for someone needing a building guide with content like yours! 👍👍

@drewsey5733 3 года назад

I stand by these gy6 motors as one of the best engines to learn how to rebuild an engine on. They’re a great first project. The best second project would probably be something like a predator 212. A small lawnmower engine. But these engines are super forgiving, you don’t have to worry about the bearings as much because it’s all roller bearings. Very simple project to learn the very basics. It’s the first engine I ever rebuilt. My rebuilt motor is super sketch and idk how long it’ll run for but it does run, and it does run well. My issue now is with the stupid cvt.

Great videos, something to note. The wrist pin clip should be installed with the open end facing up or down in reference to the stroke ( I couldn't tell the witch way you did it, not saying you wrong). If they are perpendicular to the stroke, inertia could cause the clip to come out. Thought it would be something for your viewers to know. Really dig your videos, love that setup table!

@MRT_H 5 лет назад

Guessing there is a witness mark on the crank somewhere that should be lined up to make sure the cam is timed to the crank? Sometimes when you drop tension on the chain the crank can move and set the cam tooth or two off once put back together. But maybe this isn't an issue on these?

@JG-iw8mh 5 лет назад

Never been a problem for me. Line the dots up and let it hang. Although i keep tension on the chain by placing a screw driver in it while its hanging.

@RedBeardsGarage 5 лет назад

You would have to spin the engine to get the chain out of timing.

It's better than a gy6 but not fast by any means. flat ground it made 65km/h on gps, downhill it could make 75-78km/h But i have very light rollers on it, 17 grams and a red torque spring. I might have lost some top speed. acceleration and torque is decent tho.

@brianmiller5074 4 года назад

Love your channel. Can you any of you subscribers advise me if I was going to buy a used kart for my yard and street (I live at a dead end). What kart would you suggest I look at getting. My plans were to purchase a frame and build from there I may go a stage 1 or 2 on a predator motor. Nothing major just a little more that the standard 6.5 hp provided by predator. I have some mechanical experience but will learn everything probably off you tube from great people like Red Beard's Garage. I have checked Ebay and FB but most everything I am seeing is mainly for racing. Any suggestions. I see some retailers that sell karts. Is there a place that sells used or just kart frames? Thanks

@rickcook5335 3 года назад

I agree that the rebuild looks easy on this motor. Just not sure I need it. My friend asked me to look at a Trail Master Challenger 150 that won't start. It's got spark and I checked the compression but it only has about 35lbs of compression. The engine will not even fire. Compression sounds very low to me, but perhaps it has a compression relief for starting. It was running fine, no smoke. They shut it off and it won't start again. I cannot imagine that the motor was running with only 35lb of compression, so I'm suspicious that the low compression is a red herring. Any advice?
