hey guys, my names devon and i have a 1999 yz125. ive been riding for about 3 years, and this is my first bike so heres a little history.
obviously you have to take what everyone says when theyre selling a bike with a grain of salt, but "supposedly" this bike was a practice bike for the kid i bought it from's uncle, who raced for yamaha and got the bike straight from the factory. the bike was ran from 99-02, then put away until 2011. once brought back out in 2011, it was run for a year, then had a top end rebuild in winter 2011-2012, and i bought it the end of summer 2012. i picked her up for $900, with a brand new rear tire that wasn't even installed, a brand new fender, hand grips, 2 bottles of 2 stroke oil and a bottle of gear oil. it had GP racing suspension tuned for track, bills pipe, pro circuit silencer, and Tag bars. plastics obviously have some stress marks, it was a 13 year old bike. usual wear and tear, but she started up easy and ran well, putted around the yard and brought her home.
since it was my first bike and i was basically learning on it, it took me a while to start actually being able to use the power, but after 2 and a half years, i can say i can rip her hard enough to have one hell of a time. the only issue this bike has ever given me was when the clutch basket blew apart in a sand pit and wouldnt shift past 2nd gear. i thought i blew the tranny, but upon disassembling the clutch i saw what really happened.
after a new hinson racing clutch basket, clutch plate and a new DP clutch kit, and 6 cans of brakleen, she shifted through every gear perfectly. and of course, as soon as i get alllllll that back together, i blow a wheel bearing! oh well..more maintenance.
so after a total of 1 year of learning then 2 years of tearing **** up on this bike, with numerous amounts of other people beatin the piss out of it, INCLUDING winter riding last winter without rejetting, she STILL hasnt had a rebuild since ive owned her. so, i decided its about that time, before i end up with an unrebuildable bike.
luckily, i just did my rear pads and rotor, and did my front pads. i have a front rotor, and i also have a set of MSR steel bars i havent put on yet either.
so heres the plan: disassemble, have the cylinder honed, the ports ported and polished, then-
-wiseco pro lite 2 ring piston
-wiseco needle bearing
-cometic top end gasket kit with thin base gasket
-moose torque spacer
-Delta v-force 3 reeds
-heat and pressurize to fix dent in my exhaust pipe
then theres all the typical maintenance ****.
-EBC or wiseco clutch plate kit
-all balls front and rear wheel bearings
-all balls fork seals
-o ring chain and 13f-50r tooth sprockets
-twin air filter
-stator cover, bolts, and gasket (my own damn fault)
-radiator hoses (blue..just cus)
-hand grips
-plastic front and/or rear brake guards
-possibly all new plastics, but i havent decided yet
im hoping to get the parts ordered just after thanksgiving, then having all the parts there for christmas break to get the build done. this ****ty part is i can rebuild it and get all excited......but then i have to wait till march or april for the weather to warm up to properly break it in
cus first off i dont even know how to jet for what im modding as of right now, none the less jetting it for cold JUST to break it in?! hell nah. im just gonna wait for spring.
also once spring rolls around id like to take it to a local shop and have the suspension revalved or tuned or whatever for woods riding and my weight. anybody know what a general cost for that would run? basically a suspension tune up and mod for my weight and riding style. also, would i want to wait to do fork seals until when i go to have the suspension done? or does that not matter? thanks
i also am going to consider taking the motor out for the build so i can properly clean the outsides and in all the crevices i can, that way i can also clean the frame and possibly paint it while the motors out. i have to look into how much is left with the shock and linkages and all and how easy painting the frame is with that in, or if i need to take it out anyway to get suspension work then that will be that. but as i said, i dont know how intensive suspension rebuilds are and if they require the shock and spring to come out? guess well have to see
however, as just mentioned, i dont know much about jetting. if someone can point me in the right direction for jetting tips or suggestions based on my mods and build, please let me know! thanks for stopping by, hope you enjoy!
