  1. Got a second hand rm and am looking for stock jetting specs for the 96 rm125. Anyone with a manual? Not trying to be cheap but parts are hard to find, expensive and am on a budget. I'm looking for needle size and float level in particular. Any help appreciated Thanks
  2. Perhaps but not jetted for that temp
  3. So it seems that you'd need to rejet and move the clip as wel as the air screw to be riding at below 40 Also how bout the pilot being clogged? Does fuel flow with the bowl removed?
  4. What does the plug look like? Perhaps it's fouled Also what is your mix ratio? I used to run spectro 32:1 and for some reason it was too rich so I backed off this fall 42:1 How do you know you have fuel flow? Have you checked the pilot jet for a block? Finally what is your "stock" jetting? Is it stock jetting per the manual specs for under 50 degrees? The bike has different requirements for air fuel mix, jetting etc for different temps and you're now operating in the coldest range. Start with simple stuff like plug check and do one thing at a time so you can narrow it down.
  5. As it turns out the longer dowels go right front left rear.
  6. Disassembled the tower on my 90 xr80 and did not pay attention to the dowel lengths. Looks like two Are longer by 1/4" or so. Can someone tell me which go where? Thanks
  7. 01 yz125 Never really had an issue....til my son started riding my bike. He's a lugger and I know my pinger doesn't like it. Long and short of it, it's now fouling plugs even after I ride. I had a 30 pilot and dropped it to a 27.5. Haven't ever changed my 32:1, same oil as always, same br9es plugs,Constant temp It used to be more forgiving in the woods but now unless it's rung out for all it's worth every 5 minutes or so it'll foul the plug. Ideas?

  9. I have since the beginning of time run either of these stabilizers because if I don't the ethanol in the fuel these days wreaks havoc with the jets especially if it sits for any amount of time
  10. Sorry about this again but I am stuck. My 97 xr80 has run like a top for years. Then all of the sudden once it warms up after like 10 min of riding it stalls out. I can start it right back up and then it'll only run at 1/4 throttle for me to limp home. Here's what I've done and I still am having the problem: Rebuilt entire carb and ultra static cleaned it, adjusted float etc Checked valves they're in spec Replaced cdi Replaced coil Replaced plug Checked compression which is in workable range Replaced left side cover which was busted from the chain flinging and let in dirt/mud Now it starts harder and still has same problems Btw I have always run k100 or sea foam in gas. It has a good spark when I ground it but am wondering if I am missing something. Is it possible the stator is bad and once I get past 1/5 throttle the spark weakens? I didn't think that was possible. Now I'm getting aggravated that what I'm doing is turning this thing into a money pit. I'm about to drive this thing off a cliff. Ideas?
  11. Done. It appears I have the same thing going on as LCXr who you responded to back in October. The exception is that my bike has a cdi. If this problem continues when I ride (it's 5 degrees now) do go for a new coil or cdi?
  12. Hi guys thanks for the replies. This year has a cdi After all the carb work I followed the electrical advice. Before I got too far as I was inspecting the valves I noticed a lot of dirt buildup in the magneto housing. I cleaned the raised portion of the flywheel and the pulse sensor( not sure of the term) and this far things are ok. From my reading I understand the next move if the problem persists would be to replace the Cdi and the coil.
  13. Update 2 Replaced sprk plug and still the same misfiring when warm.??????
  14. Update: also checked the valve clearances which were in spec. Decided to swap out my carb from my other xr80 and this time ran problem free. Returned to the shop and had them put the thing in the ultra static cleaner or acid bath....and now it runs great. Last question: can I clean my carb at home like they do at the dealer? Whatever they used beat my spray cleaner and k100. It would seem that my cleaning did not reach the inner most places which apparently housed the problem. Ideas?
  15. I'm stuck. I have never had a single issue with this bike and This just recently started seemingly out of the blue. My xr80 starts and idles cold. Once it warms up it craps out past 1/4 throttle. I can slowly roll onto the throttle more but it will not hold a sustained higher rpm. Here's what I've done: -Cleaned and replaced all carb parts -Set float height -replaced fuel line and checked fuel flow -checked for air box obstruction Anybody offer up ideas as to what I've missed or should check next?
