The 94 YZ/WR/iT project
« on: April 29, 2015, 12:22:17 PM »
At the end of last summer we found a 1994 YZ 250 on Craigslist for 150.00 Bux dead engine with a spare bottom end & FMF fatty answer pro bars. we sold both engines & rear 19" wheel $475.00 a friend gave us the remains of a 92 WR 200 everything except the engine & frame we used the 18" rear wheel & complete front end seat & tank front & rear fender & number plate w/ light, I found a 81 iT 250 bottom end ( like new well taken care of or very low time) CDI, pipe regulator for 72.00 Bux for everything on eBay, Next I found a iT250 cylinder with a fresh bore .60 w/ a wiseco piston kit in the box & a 82 YZ bottom end w/ another iT250 cylinder with a new LA sleeve in the deal for 80.00 Bux.

I did the chassis mod to move the RS down tube to clear the pipe & mod the fatty, I blasted the chassis painted, all new swingarm & link bearings shock is done engine in & its rolling were doing a little plastic paint work should start er up next week.

Its looking good Mike, Great Job. ;) I will  be curious on how it preforms with the added head pipe lenght. That should pull the peak RPM down. I will be also curious on the jetting with the added head pipe lenght.

A little more done today in between, using Krylon Fusion plastic paint works well..

We tried to start the project on Saturday no good I thing the CDI has a problem fires 3/4 times then nothing kick a few times firing again only 3/4 sparks. I checked the stator/charging coils & pulse coil & Ign coil all are in range. I'm thinking that's why the engine is so clean had a CDI problem & some one parked it.
