Watch out for this on your polaris 400!

Both the early and the late series mikuni carbs will fit on either a late or an early 400 as long as you have the right throttle barrel for it.

I love 400 Polaris! Also I call it a "slide" rather then barrel. Round slide carb Flat slide carb Ect..

[@shanegrunke4256]

It's actually just the fuel needle that's different in the carbs. Old engine cylinders had 4 intake ports, 1997 and up cylinders have 6 intake ports

[@billallen4793]

Steal the gearbox from that explorer and put in in the scrambler so you'll have a low-range sport quad!...from Wyoming USA 🇺🇸 👋 🤠

[@TheEvilRoosta2014]

Liftmasterdoorman people who build these motors run in to i quite a bit. A few people i know have had it happen a few times before.

[@wisco-lad]

I had a 400 scrambler about a year ago.... Im thinking about purchasing an explorer 400.... Are the explorer 400s as snappy as a scrambler?

4 years later and never said what the mistake was?

[@KingSalmon]

Counterbalancer/waterpump assembly. Looses tolerance overtime and once it reaches +/- .015 of slop, you will throw out the mechanical seal. Goes unnoticed till it's too late.

[@KingSalmon]

In my case, the counterbalancer/waterpump unit was so worn, that it ground right into the lower section of the case ever so slightly. Which caused the cast aluminum case to have a slight fracture, and run lean which caused the motor to melt down.

[@chadjohnson7712]

@@KingSalmon Thanks for the heads up just I got done rebuilding a 95 scrambler 400 I did a new top end its bored one over I didn't do a bottom end cause there was no play in the crank and I read the bottom ends are strong on these. Looked like new inside the motor it holds coolant no overheating. Outside was a different storey the whole motor was just soaked in oil but I cleaned and polished the motor up repainted the whole frame I was doing it to sell but im going to hold on to it for awhile i like the power it has. I did notice at low idle the motor moves alot more then I thought it should. A little above idle it smoothes out I put new counter oil in I read the motor movement is just a natural polaris thing being a big 2stroke? I also had to pull the motor and fix all the motor mounts and bolts. I don't like setting the idle so high where the motor stops vibrating cause then putting it into gear it grinds I guess I gotta find the sweet spot for idle I probably have it turned down to much and the motors lugging causing the motor movement.

[@lukehouston101]

how can I get in touch with the guy that rebuilt the yours

[@KingSalmon]

Here's the guy--- polarisatvrepair.com/

[@lukehouston101]

how much was is for the new block and everything

[@KingSalmon]

In all, around 600 bucks.

[@KingSalmon]

If it's just a top end then it's around 200.
