Hi All . . .

I have a 96 Xplorer 400 2-stroke, but I need a 4 stroke machine.

I know that I can sell the bike and buy a new one. Getting $4000 . . . if I'm lucky . . . and plunking down another $5000 . . . is well . . . difficult right now.

I was thinking about an engine transplant of another 96 Polaris . . . a Magnum 425 as the chassis is the same and both riggs are chain drive?

I can then sell the 400 motor as it runs just fine . . . I just dont like the 2-stroke blue smoke.

Any comments? Anyone do it?

 

You may need a re-build, my 2 stroke only smokes at start up which it should??

 

The swap you are talking about could be done if you had lots of parts like oil tank exhaust carb airbox motor mounts.It would be easier and cheaper to trade for a 425 Magnum.

 

ftwflh . . .

I see you have the machine I'm considering. You are correct in the fact that I would also need an exaust, carb, etc. Never thought about motor mounts though. I would almost have to put a 425 next to mine an do a visual.

If I could get a bashed 96 425 then the parts swap should be rather painless . . . depending on the motor mount thing.

 

Let me know if you find a crashed 425 I need a heat shield off of one.And keep us posted on how it goes.

 

It seems like a drastic solution to a small problem (blue smoke). I say just put up with it for now,,,,and make the next quad a 4 stroke.

 

I bought my Xplorer in late 1996. Up until about 18 months ago my wife and I used the bike with little problem. Since that time we have both developed chemical sensivities (not the illegal kind [img]i/expressions/face-icon-small-smile.gif[/img] ) and are "allergic" to many man made chemicals including the 2-stroke blue smoke . . . even after the bike was tuned. Where 4 strokes are cleaner burning we dont have as much a problem with them.

It may just boild down to the fact that I will have to sell her - bike not wife - and buy a 4 stroker as getting a bashed doner 4 stroke may be difficult.

I have even thought of replacing the gasoline motor with an electric one from a forklift or some other similar vehicle. I believe that I could also eliminate the tranny as well as electric motors are high torque and are reversable. Battery storage may be the problem . . . unless I hook up some soar panels . . . Hmmm.

 

If you use the Polaris sythentic gold oil, you don't get the blue smoke. I switched over to it, and the blue smoke is gone. Maybe just a little on start up.

 

Definately try a synthetic oil first. Try a couple different brands if you need to. Also check the oil pump to see if it's properly adjusted.
