4/7/2025 3:44pm Guys, gals, I have some leftover parts if anyone is interested. They're up on eBay currently. Full Yamaha front spoke set. Full (plus extras) Yamaha rear spoke set. $120 for each set. Way less than what I paid. I did mount some of the spokes on some newer rims but decided to stick with stock instead of aftermarket (Thailand) rims...

4/7/2025 3:28pm Great job! Good looking bike! I just finished a 1983 YZ125. Man, talk about hard to find parts! These old girls should be saved and restored. Nothing like the old two strokes!!

4/7/2025 3:06pm Finished my 1983 YZ125 build and found that the carb that was on the bike was a cheap Chinese piece of junk! I bought a new Mikuni VM34SC to install but am unsure on the jetting. The bike has a DG pipe and silencer so I'm not sure if stock jetting will be good enough or not. Also, I'm running...

12/5/2024 7:44pm I don't want to do it that way! I want to buy a complete set, ready to go.

12/5/2024 5:12pm Ok, fellas, and hoes if there are any...🤑 Anyone know where to get an engine bolt kit in black at a reasonable cost? I'm going to build the second engine I have and a new bolt kit is pretty much all I need. Peace bros!

12/5/2024 10:21am Great site! Thanks, bro! I'm pretty much done on the full rebuild but have a second engine I'm considering rebuilding/fiting out. Anyone have a cylinder head cap they want to part with?

11/11/2024 5:02am Guys, can anyone recommend some wide foot pegs that will fit the 83 like the stock versions without any modification? Reasonably priced also.

11/8/2024 5:28pm Guys, have a question on the power valve. In the diagram below, the part circled, does this go on last to hold down the “guts” of the valve?

11/8/2024 4:17pm Almost there! Waiting on a few additional parts and it'll be ready to fire up. I did check spark today and do see some on the plug so my fingers are crossed! That DG pipe I bought off ebay, man was it sticky and a bit rusty. I guess from sitting around for so long.

11/6/2024 4:07pm Got the engine put together and in the bike today! Moving right along... I'm hoping the damn thing starts when the time comes. The stator issues still have me worried. I put in a 1982 CDI, coil, generator, as it was said to work with the 1983 so we'll see! Those cheap ass Chinese hoses are a bit shitty I...

11/1/2024 2:16pm Been working on a second fuel tank. Received the decals today and finished the sanding/polishing. Not sure if I'm going to part with it or not just yet.

11/1/2024 5:14am Don't buy them then, bro! I've been getting my ass gouged with everything i buy for this bike! You think I'm going to lose money, you're nuts!

10/22/2024 3:49pm Some updated rebuild pics for those interested. Got the motor ready to go for when LA Sleeve returns my cylinder. Fingers are crossed the stator is going to work the way I had to set it up. Also put a shock cover on the blue spring. It looks better! I also found the correct size "mono-x" swing-arm decals!! Check out...

10/8/2024 3:45pm Got the rear shock back today from Pro-Action. Kind of looks a bit off kilter with the blue spring but I couldn't find anything yellow or black in 5.7kg. They were able to get the dampener knob off with great effort. They had to make me another adjuster to fit in there as the original was destroyed. I need to...
