LOL its all in the Ignition tell him to double check all the components (Stator, Lose pickup in the fly wheele, Ect.)... It is the motor running back wards. So some thing is way out of wack...

I heard somewhere that 2-stroke motors can run backwards. Try to push start it (in the right direction) and see if that fixes it.

I would not advise really trying to pop start it, in this case it may mess things up. If the motor tried to run backwards, and you try pop starting it, making it run the right way couldn't it bend a rod or something worse from the jolt of the motor quickly changing direction??

Wait, so the bike starts and runs, but when you shift to 1st, what does it do???

You can get some motors to run backwards which is not very good. My tecate was off a little, but it wouldnt fire. What happened to mine is that the stator was too far, causing spark before it should and the kick starter whould shoot back and literally give your foot a bruise on the bottom. A 210psi motor kicking back HURTS LIKE HELL.

Im lost as to how you guys actually got it to run backwards and keep it running.

Correct me if Im wrong, but I believe that some older quads had the ability to actualy run in reverse... in order to achieve the desired reverse direction, instead of have a reverse gear. Pretty cool, unfortunantly that doesnt help your problem at all.

thats what I am thinking

Double check the stator.

2 strokes can and will run opposite direction if the timing is 180 off........different engine's have used this in the past to get reverse.

I had a TRX250R ('84 air cooled) that would run backwards. I found out the hard way....trying to climb a hill, killed it, and let it roll backwards a bit before I let the clutch out (no brakes) to slow it down. It started right up. The rotor key had been sheared I guess...never did run right. I got it home (backwards) and it needed crank bearings anyway, so in the process, I pulled the rotor...and yep, sheared key. New key, crank bearings/seals and it ran like never before...and I sold it not long after. That thing was a death trap!

Timing issue I'm sure. Old Detroit diesels would run backwards, we had a tank truck that always got parked far from the building for when it actually did start backward...

yeah... like everyone has said its your timing. its actually quite usefull that 2-strokes can run backwards. in many snowmobiles they use that instead of adding the wieght for a reverse gear.
