New-to-me YZ250
I'll try to make this short. At the Penny Pines group ride over Memorial Day weekend, CJ let me take his YZ250 out for a spin. I was hooked. As luck would have it, Eric B had a co-worker with a 2002 YZ250 that was just sitting around decomposing in his front yard. A week later I'm the very excited, somewhat shell-shocked owner of a well worn, but mostly intact, 2002 YZ250.
What follows is three months of complete disassembly and replacement of virtually all moving parts, plus some that don't move: re-plating the cylinder, all new transmission bearings, crank, piston, rims, tires, shock linkage bearings, wheel bearings, steering bearings, final drive, etc., etc. Plus all new plastics. Invested twice as much money in parts as the original purchase price. Not to mention the innumerable calls and texts to CJ for advice and tools (couldn't have done it without him). Finally finished it about two weeks ago and have taken it to Metcalf a couple of times to start re-learning how to ride a two stroke. For your entertainment, a time-lapsed video I put together of the assembly. youtu.be/5_S63TH2QkQ |

Nice!
I'm about to put all the new stuff into my YZ250 engine (cases already split). You work pretty fast, will you do mine? should only take you, what, 3 minutes? Looks like you are making it into a trail YZ? Will you be racing it, too? More mods to come?

Had not heard about this project Leo. CJ tells me 2002 is the year to have. I can't wait to see it at Stony. It will be a ripper.

Awesome, I especially like the project manager early on in the video. But all that work and it's the wrong color!
Team YZ is going to shred at StonyBARF. I'm even bringing spare tubes for you know who.

I just had time to watch the video -loved it and she started on the 2nd kick!
If you don't need a plate or long range, there is nothing like a 220 lb. two stroke off road bike, specially if you tune it for low end torque. I can't wait to see it Leo!

How to carry enough gas or get fueled dropped is the biggest issue to overcome. Neither easily solved. I'm not trying that trail again on the 650. Someday I'll have a smaller lighter 4T desert bike to attempt it again.

The hardest thing you have ahead of you is trying to get the transmission and shift drum into the case. I did mine twice just to make sure I got it right, and no, it wasn't much easier the second time. Combination of skill, patience, and a little luck. Right now I'm trying to get the suspension sorted and learn how to ride it effectively. Needless to say I need a much different riding style than with my XR400. But - it does pull surprisingly well, and I can bog it way down without stalling it thanks to the 11 oz Steahly flywheel weight. As for racing - no immediate plans, but who knows? |
