As many of you know- I have fairly recently acquired a Lakota. The thing is, I'm seeing information that the 300 Prairie- which I understand used the same engine, had 10.2:1 compression while the Lakota, while billed as 'sporty' ran a paltry 8.6:1. And can I get away with pirating a piston from Prairie, or even an 11:1 Wiseco?

Hey kwackermann, i now they make a praire 360 and 650 but not sure a 300. I know for a fact that the lakota motor is from the bayou 300 and it is tuned for more of sport riding but they are the same thing, that's why the lakota does not have to much sport performance like newer racing quads, it's more in the sport/utility. But with a nice pipe and jets and stuff it sure wake her up a lot.

. Yes Vunit, just before the Prairie 360 was released there was a Prairie 300 and 400. I'm kinda looking for a P300 4x4 because it doesn't have all the actuators all over like engine braking and what have you.

Kwackermann what do you want to do with the praire motor anyway.

i thought it was based off of the bayou...the lower compression helps it run cooler...which probably isnt' a problem to about 12:1...my 11.5:1 added a lot of torque to my mojave

Wow, a half a point in compression- didn't think it would be really noticeable. The stock 'jave compression is 11:1 outta the box, which I thought was fantastic. Certianly a higher compression piston is in order for the Mojave- probably when I do the cam work and everything else is apart. I'd like to go about 10.5:1 on the Lakota, so the next time I see a piston on ebay- it's in order...........

i donno it sure seemed more powerful

That's cool. Say, Rols- do you need a green sticker to ride your quad up there in Wisconsin?

What's the reason for this.........
 

you gotta register it the color changes every year this year is orange...perfect match for my plastic...there are some really nice trails in blackriver falls and farther north

Gotta really watch when bumping up the compression on an air-cooled bike. Go too much and it will ping and you can only run race gas.

Water cooled stuff is a little more tolerant of higher pressures.
