The cam is in the head, it has lobes that move the valves in and out.
Don't get blown away with camms yet, the stock one in the lakota isn't that bad.
You can get a high comp piston .020" over, a standard size would probably work on a new bike but I heavily reckomend going one size up. But this will give you quite a bit more low end.
How many HP, good question, I'm shooting for 25 my self but not sure How far I need to go to get there. Unfortunately it won't be for another month befor I put it on the dyno!!

 

if i go one size up what would i have to do, get bigger sleving and stuff? if not what size is it? you told my 10.5:1 is that it?

 

8.6:1 is the stock compression. You want a 10.5:1 high comp piston that is .020" over bored. You will only have to bore this piston in.
You could go with a stock bore size but it is best to go .020" over this way the new piston will be sized correctly to the cylinder.

.020" is how much wider you make the diameter of the sleeve, compression is determinned by the type of piston you put in.
No resleeving is required for a over bore piston, just a simple boring by a machine shop. You can get a .020" bore job done just about at any machine shop.

 

ON my mojave can i go 2ed oversize and would that give me 10:5:1 or what would it be?If i just put in a 2ed oversize pistin would i have to do any thing else,cams,valves ext.How much of a difference would going 2ed oversize make.Just alittle or like night and day.Would i be able to keep up to a 400ex?

 

mojavekid13,
The mojave comes stock with a 11:1 compression piston, and no not much would be felt with a .020" oversized piston.
If you went with a cam, some port/polishing and a black box mod, you would feel a graet deal in your top end.

 

oh i didnet know that,Thanks gaff.But already have webcam race cams so what else could i do besides port and polish.

 

OH ya i forgot to ask.Will a black box of a KLR250 make a difference?if so how much higher will the reves go?A stock mojave is 8500rpm isent it[img]i/expressions/face-icon-small-confused.gif[/img]

 

I kinda got lost in the dialog, I'm ordering the 330 FST kit, this lip you speak of, is it on the lakota, Mo or both? does the lip have to be machined off prior to pressing the sleeve? Can I press the sleeve myself (I have a 30T press), or is this better left to a machinist?

 

sorry about that, hossman and I have been on here for some time, and, well we kinda leave little things out that we both know one another knows already.

The sleeve on any quad has a lip that sits in a groove on the top of the jug.
What I'm referring to is usualy a replacement sleeve's lip will fit in the already existing groove, the FST kit comes with a sleeve wich doesn't fit in this groove another will have to be machined.

Trying to press out, machine, and press back in a sleeve isn't the easiest thing to do, and being a aluminum jug causes the level of difficulty to go up.
Then your looking at having the new sleeve bored to the new piston thats provided in the kit.
Now knowing this and how critical it is to get the tallerences correct, I heavily suggest you go to www.wesleeve.com, and call Mr. Echoff and have him do it. He charged me $115 to do it and he does a graet job.

This will leave you much happier with the end results.
