traded xbox 360 for this bike.. excited

[Green Machine Beast]

some guy thought it was seaized after he installed new piston and rings.. said it was stuck.. so i traded him, then went home i took magnet and put near crank moved it around some and pushed on kicker.. and out came a bolt and nut he probably didnt notice that fell in.. turned right over no problem.. missing caliper and rear plastics.. looking for advice on the bike she had pro circuit pipe fmf powercore silencer carbon tech reeds new spark new oil.. just top end a lil boggie not sure why.. main jet?

[Green Machine Beast]

thats my old 1987 ktm mx 125 miss her.. but i also have a 1986 ktm 125 mx.. oh thats my boys 1990 kx 80

[Green Machine Beast]

there is the ktm again soon to be more pics of the 500 only have one right now which was already posted

[1989kawasaki]

thats a cool 500  , some new plastics and youll have her lookin like new 

id trade my xbox360 for an old kx500, sell it, buy a boat load of parts for my other bikes then buy a new xbox 

[Green Machine Beast]

that might be my intentions but idk might keep her shes an oldie but goodie and dont make no more so might have onto it and sell my 86 ktm

[Green Machine Beast]

its a nice bike and would be my first time on a bike bigger than 125 besides a quad haha.. bike runs really good just not sure why top end is boggie slacks in power.. thinking jetting issue with bike havin aftermarket parts

[Friar-Tuck]

 Can you see if the kips is moving?  If I'm not mistaken the older bikes have less moving parts.  This might be holding your top end back.

that be an 87 KX5.that x box has done you proud.eventually. welcome K.

you mite find with the mainjet that bcoz of the improved scavenging capabilities of the pipe you might have to go one size down on your main jet to get her to percolate.checking your main bearings by grabbing flywheel and trying to move it up or down to check for play is your first job.checking  crank seals and gaskets and cases/inlet for air leaks is your second.read sparkplug for jetting clues after checking for airleaks.check what jets carb is running b4 doing jetting.hth.K.

i kno it gaskets good well top end i put them on but bottom end not sure didnt check but doesnt leak no type of fluids and afterr i put reeds it seems liks it want to hit but i havent really pushed it still in breakin in stage on piston and rings heard u must wait and all together prob between idle and quick spin bike has been on mayb 2 hours in my posession.. and whats kips how do i see if they move, when i took bolt out to and assembled crank was good no loose play

[Green Machine Beast]

i will try smaller main jet size and spark was nice brown color so thats good so think im close to where i need to be checked that yesterday after putin new spark on

[kwakman]

brown is close, be careful not to go to far down, she may have been dropped already....what no is the m/j?K.

[Green Machine Beast]

300 somethin but on that carb mikuni 38mm realized main jet sleeve was broken where u screw it on so i replaced carb with keihin 36mm pj carb 170 main 68 pilot runs great low mid and top but wont idle and when i turn on gas to start it.. carb leaks alot from overflow line on bottom in back dont know why.. to big a pilot?

[kwakman]

worn or badly adjusted fuel valve/seat.she'll go better with a 38 or 40mm vm, 40mm was standard 86 kx5 carb,went to 38 in 87.K.
