I've had 3 yard dogs they all ran weird except for 1 i replaced the cylinder and piston and rings on 1 because I broke a exhaust bolt and the 1 I replaced it with ran great that's the difference between casting cylinders and injection molded cylinders like the 80 cc but you did a outstanding job sounds awesome brother ride safe

And I just seen you aren't wearing a helmet... Please wear on bro . I didn't . And I'm regretting it ....

Glad I watched this before buying a YD.........Oh yeah, I seen pop up aftermarket pistons for chainsaws. I'm pretty sure I seen a 2 ring 52mm pop up that would fit an Avenger or P85.....I'm thinking a properly ported Avenger 85- with 2 ring pop up piston- the aftermarket head- expansion pipe & good carb. I'm having trouble understanding how a 47mm Mineralli could make more power than the above 52mm engine.

I've successfully changed my account name. Let's see if it shows up already

My yd100 runs hotter than my phantom 85

yd100 ssuking suck i had one bt100s bt110s and avenger 85s are the best

I remember years ago when the yd100 first came out, mine came with two base gaskets Sooo I thought naw I'll only use one base gasket thinking I'll get more compression. Lol well the piston pinged and pinged kissing the squish band and I just figured that I needed higher octane not knowing the piston was hitting the head. Well it blew-up after about a month.well It bent the rod lesson learned. Always check the clearance with solder. Never guesstimate. Never ever ever ever.

I put an electric front wheel on mine to help me make it up hills if you want to check it out. Nice ride!

I just drilled a bunch of holes on the bottom of this new one I’m working on and it helped a lot like almost 10 mph better

Hey bro it's me Benny bro you did a good job on that motor it sounds real good you know me I prefer aftermarket pipe I like everybody to hear me coming I don't want everybody thinking that that's a regular bike plus I like the performance and Power but anyway you did a banging ass good job this video and the graphics bro you have outdid yourself real talk with this one and leave that rabbit alone the rabbit is going to get us in trouble ,but that is a nice pretty rabbit I seening it sitting on your desk but the one that you was talking to I didn't like that's the one that's going to get you in trouble 😂LoL 😂real 💯 talk though but keep up the good work bro you know I keep watching bro

lol your like one of the only people that I watch the entire video in one sitting 💯 thanks for all the information 🔥

Wut up Johnny.... Or I mean Uncle Johnny... That's the best port work I've seen bro.... In the head too... Love your yd vids... You know your the reason they made the ld 100... Your the first to cut the yd head .... Chinese copied you ... I got my friends ld running great.. it was crap B4... I had to do alot if decking and porting .. . Yd 100 s are the shit wtuned with a gud pipe.. and carb.. ... And

I assembled 3 bikes several years ago ( one at a time ) .

Longer one, but great info for all kinds of builders. The restrictions are real. Thanks for the ride.

Good video

Damn I like that little setup that you got for measuring your port timings 💯👍

You should try an avenger you'll throw all those yd100s away 😅

Crazy how much those exhaust restricts the engine

I'm quite sure your method of checking the clutch spring lock thingy was explained so clearly that an old fart can understand. My clutch popped a couple days ago and I've been sure it was this. Now I'm moreso convinced that cutting 1 of my many Allen's will make several clutch lock thingies!

I appreciate your detailed builds and the way you unintentionally show tour thinking process into why you want to do somethings, seems lately everyone shows afterwards of a their build and rides. Your videos, you explain, so many don't and so many are not..too helpful. I learn and develope my own ideas from your videos of how i want to build an engine. Keep up the good work you do
