Thank you so much. I own a CBR600RR, but I always wanted a supermoto. Got a DRZ400 because of the low maintenance it requires. I ended up loving these bikes and now I want something for the mountain. I 've had my eye on MX bikes for quite some time now, but I 've always been skeptical about the maintenance. You just showed me that 2 strokes are, in fact, easy to maintain and you might have sold me on a YZ250. Or a YZ250X, almost the same bike. Immaculate 250 you 've got there, by the way.

Liam Jones honestly the ease of maintenance on them is one of their best attributes. Sure you may have to do it a bit more often, but parts are way cheaper, and you can do most of the work yourself. I was on four-strokes for a number of years racing, but came back to this and I don’t have one regret. Thanks for the comment!

great video.. i seen you using prestone coolant like i used to do but i got a digital temp gauge to keep on eye on temps and when i switched to ENGINE ICE coolant and added 1 oz of water wetter super coolant to the mix...no bullshit my bike runs almost 10 degrees cooler once fully warm and maintains peak power longer....and i kept the control factors all the same as in same plug..same day air temp and humidity ... same premix......etc etc... and im running 8 degrees cooler now...not so important with motocross as running 2 strokes hard actually keeps them much cooler but if on single track tight trails for extended periods of time that can def make the bike run alot hotter and eventually that heat stress will shorten motors life some but even though my yz is a 2010 its basically same bike.....SO YOU SHOULD HAVE SAME RESULTS......

DO NOT put a stone hone like you'd use in a Chevy small block or other iron block engine in a plated cylinder. The surface hardness on a plated cylinder is ridiculous. Just clean it up with a scotch bright pad to get it clean. When the plating fails get it replated or buy a new cylinder. Don't put a normal 3 stone hone in it, you'll destroy it. It's too abrasive, it'll take the plating off... Then you'll be running an aluminum piston in and aluminum bore, with steel rings. Best case scenario you'll seize the engine and trash a piston and cylinder. Worst case you'll have to replace every engine part.

@turdpike

You’re just checking the gap of the split in the ring when it is installed in the cylinder. Too much gap is bad, and too little is bad too, for different reasons. Very important to check it prior to buttoning the thing up. As far as where to get piston kits, that’ll depend where you’re from. If by chance you are Canuckistani like me I order Vertex piston kits from Fortnine.com typically

You'd have to be an idiot if you can't do this. I've done dozens of top end rebuilds on bikes I had no experience with. They all have basically only, 12,10,8 and 6mm bolts. It's incredibly easy. Bottom end is a little different, still not that hard. I don't have the press or jig to rebuild a crank. I just take my cranks to a bike shop that has the tools. They press it apart, replace the parts and true it. Put it back together. Get a manual this shit is easy.
