Help Me Need 98 Kx 125 Cylinder And Head

[lance]

I am in desperate need of a jugg and cylinder head for a 1998 kx 125 contact me if u know where i can find these parts!! thanks

[dlowe102]

i would put a 99 00 01 02 cylinder as the 98 powervalve was a little to close to the piston and would barely contact it

[lance]

i was told that i could not interchange years?? i heard that i could only get a cylinder for that year only or it would not fit right??? is this correct??? ive checked all the local dealers and thats what there telln me.1998 kx125 only takes that year??

[dlowe102]

they just go by part numbers and yes the 98 99 00 01 all have diff part numbers they have diff porting i think the 01 02 is the same...if you were to get any one of the cylinders it should work they are the same design and everything just better port timing through the years. although i could be wrong but i doubt it

i was wondering have u ever tried or seen this done using the upper year of cylinders put on a 98 kx 125??? i just found out that my cylinder was dicontinued!!!!!! which sucks and nobody over on my end can give me a straight answer on what u said about the other years fitting!!! im just afraid to buy a 99 through 02 cylinder and it not work no what i mean, write me asap man i would really appreaciate ur help!!!!! thanks

Is it totalled?

If not give a shot at fixing it with say LA sleeve or a shop like that.

i dont have a cylinder or head thats how the bike came but the bike is MINT!! just cant find jugg, no whaere i can get one

[dlowe102]

so you dont have the cylinder or head? so that means you would need a complete cylinder,head,and powervalve. If so YES a complete cylinder off a 99-02 will fit for sure. i was just worried about the 98 powervalve working with a 99-02 cylinder even though they are the same design the 98 went a little further to the piston to seal better and when really hot like on the gas for a long time in deep loam would somtimes contact the piston on some 98's
also the 98 the valve would open all the way and over extend at times and sometimes get cocked open. pro-circuit sold a powervalve cover that had a set screw that limited it from over extending and therfore not **** itself into that stuck open deal. i raced this model extinsively it handled soooooo well had a great midrange hit. but if you are using a complete cylinder head powervalve off a 99-02 i promise it will fit and work great.

You dod not even have the core parts to turn in, so have you looked for a parts bike, or a complete donor motor at least.

As dlowe said already, another jug should work from those years, and you need a new piston, and pin, bearings, etc anyways.

How are you for a crank etc?
