I wasn't going to do a project build since I'm still low on funds after the crazy YZ315 build I did and now a 2020 YZ450F...but here we are.
Found a rough, blown up 94 YZ250 on OfferUp back in August. For some reason, I always loved the very 90's look of the 93-95 YZ's and had to have it! Was just going to get it running and just have it around for my friends and family to ride. Basically a bike they can thrash and not feel bad about it.
Problem is, I can't leave things alone. I have to wrench of something at all times...
So now here we are. I was just getting the bike looking fresh, greasing the bearings, new steering stem bearings and what do I find on eBay? There it is, a DeVol linkage! That's all it takes for me to want to start a new project. One little part that's somewhat rare to start a build. I guess it's time to start building.
Not 100% sure which direction I want to go with this build yet. Was thinking either a more hardcore WR style build with stronger (Tom Morgan porting), smoother power, re-valved, re-sprung stock suspension to go with it. Thinking almost like a modern YZ450FX feel. But with that, it will look like an old YZ replica. Almost something you could race the Glen Helen 24hr race. (Yeah, I saw RMATV do this but I had that idea before they even did it)
Or I can go the route of an actual replica which plenty have done. Hard hitting, stiffer suspension. Still undecided since I'm still browsing the web hoping to find some parts. Plenty of people have done this. I was thinking of doing a long rod engine, but Tom Morgan talked me out of it...although it would be very cool.
I will be powder coating the frame with the OG dark blue metallic paint. Will also want to vapor blast the engine, swingarm, etc.
Some other parts I am looking for.
-Works pipe
-Ti Subframe
-Blue plastic shrouds (Only white and black for sale new)
-Frame guards (DeVol I believe?)
-Radvalve
Jetting was 40 pilot, stock needle 2nd position, and 350 main. A/S was out far enough to cause a lean bog. Way too lean of jetting, especially trying to ride it in the desert with a paddle.
I threw in a 45 pilot, and 390 main. Runs really well with this old Mikuni carb. I see no reason to swap to Keihin at this time.
Also waiting on seat cover. Will be going with the same one, but I want to go with new foam and possible the grippy version from Evo-MX
I went with the number "823" for now since that is my wife's birthday. Have to make her happy!
Funny thing is, it was very easy to ride. Very comfortable and didn't tire me out even sliding all over the bike. Power was plenty as well.
With some new bars, grips, seat cover, porting, foot pegs, tires and suspension re-valve, I think it will be an easy bike to ride fast.
When I got home I swapped to much more modern Pro Taper Evo SX bend with better grips. Haven't ridden with them yet.

Rear integrated rear brake master cylinder will fit as well.
Maybe in the future I will try SSS if I can find it cheap.
Good idea on the rear integrated. I will try to find a cheap one on ebay
Bolts right up with no issues. Anyone have a good starting point for jetting? I threw in 172 main, N3EW 2nd pos and 50 Pilot. It was very hard to start, plug immediately got oily due to being too rich on the bottom. A/S didn't really make a difference, so ordered a 42 and 45 pilot to try out.
I have a set of 2020 pegs sitting there for my 1994..
Cheers
I have a 96 Wr 250 which is basically a 1994 yz. I just found some YZR race team graphics and seat cover from 1995, and I found a devol link for it too on eBay. I’d love to find a pc silencer for it because I have a pc platinum pipe, but the crown jewel is I found a YZR long rod kit in the package still in a small dirt bike shop in SoCal. I stumbled across a YZR cylinder but way too pricey for me haha. I found a set of blue shrouds maybe a year ago but nothing lately I had pro action do my suspension I ordered a Scott’s stabilizer over a year ago but I guess my order dropped of because of the age lol. My buddy had a FMF mag cover laying around so I snagged it. This thing is a blast to ride!!!

That bike is mint! How much are they asking for long rod kit? Asked Tom Morgan about building me one, but he talked me out of it.
I think I payed like 75 with shipping, I did notice a difference in the power, with the WR gearing it made a beast of a trail bike. some of the tighter stuff normally is 1st but now iv got the torque to pull 2nd on some of the nasty stuff and not spin the tire like i would in 1st gear. I haven't had it out in the wide open desert yet so kind of curious.
haha look what i found https://www.vitalmx.com/community/dezracr,71352/setup,90381
