    Q's on Keihin needle

    The KRAN, I'm confused on your 2 post here. I'm a newbie trying to learn. In the first post you say If the air screw is less than one turn out you need smaller pilot and if more than 2 you need bigger pilot. In 2nd post you tell him he needs smaller pilot with the air screw out 2.25. Am I missing something or just reading it wrong?

    Repacking used FMF Shorty

    So I tried saving some money and purchased a used 2014 KX85 FMF Shorty Silencer in "Excellent Condition". Ya and as usual I get the shaft. Lol. It came in not excellent condition bit It can work for what I'm doing. The question is it definitely needs a repacking. It has 3 screws on the pipe side and 2 rivets on the exit side. Every video I've watched just shows removing the 3 screws. We have tried and tried to get it apart. Used rubber mallet but it keeps wanting to come out crooked and gets wedged. Any suggestions? The two rivets don't need to cone out do they?

    2010 KX85 bogging down

    Ok. I will check them next. It has Boyesen carbon reeds in it that have about 15-20 hrs on them. Im not in front of my notes so I don't know which boyesens I have in it. I believe it's the pro series carbon. If they are bad would the Boyesen Rad Valve and reeds be a upgrade?

    2010 KX85 bogging down

    I'm going back to all stock jetting and starting all over. I've road a few different guys bikes and it's nothing like this.

    2010 KX85 bogging down

    I've already been there at the 3rd clip with same result.
  6. I have a 2010 KX85 for my son. It is completely stock. Currently has 140 main, 52 pilot, 2nd clip on needle. 1-1.25 turns out on air screw. We tried different jetting but it seems to really bog down in 2nd when he gases it coming out of a corner. I know you need to keep it up on the pipe but it takes it a few seconds to come to life and by then not enough momentum to clear jumps. Where would you start? Has about 10 hrs on complete new bottom end and top end. Never has been right.

    Got my son a KX85...

    I bought my son a 2010 KX85 this summer and he rode the hell out of it. We just started getting the jetting close to make it run well and Bam lost the rod bearing. We ended up doing a full top and bottom rebuild. Should be done this week so we can put it back in and see if it runs better.

    Stalling issues at takeoff

    Well I didn't get the results I was looking for. Changed reeds and didn't changed much. If I'm idling along and gun it it takes couple seconds to wind up. We no longer have the oil issues and the plug looks pretty good, maybe tad on rich side but definitely not what we had. It more of a very dark brown. It idles like crap, will set there and idle perfect for couple mins then just die. Pilot jet 45 Main 130 Clip #2 position. Any suggestions now?

    Stalling issues at takeoff

    OK here is what we have found. The oil issue has quit but the bog hasn't. I had carb off so I pulled the reeds. Bingo, just as KRAN had said. They were very bad, especially the top one. I have ordered new ones that will be here Tues. I'm hoping this helps.

    Stalling issues at takeoff

    Thanks for all the advice. KRAN, it's ran this way since we bought it used a few weeks ago so Im not sure if it ever ran well. Honestly I think the people we bought it from know less about it than me. It had been sitting since last fall. We are going to try some different jetting and see where the needle clip is set and go from there. Those options are alot easier than tearing motor down to check seal. 😉.

    Stalling issues at takeoff

    First off I love this site. Great for newbies. Have had many questions answered already in a short time. Now.....Son has a 2010 KX85. Runs decent but it seems very rich. Plug is very oily and damn near has raw oil coming out exhaust. While practicing motocross starts he winds it up with no blubbering but drops clutch and it almost died and takes few seconds to clean out. Seems fine at mid range and idle. Running 32:1 gas as per manual Has 135 main jet and I havent checked to see where needle clip is. Ambient temp is around mid to low 80's and testing this is after engine warmed up. I can tell you it's running so rich that you can lay your hand on motor after 30 mins of riding and not even come close to burning it. Lol. I big into only changing one thing at a time to see what difference it makes. Where you guys start? Thanks

    Jetting help??

    PS:. It runs very good on the top end once you get it going

    Jetting help??

    We are having same problem. We just bought a used Kx85 and when he goes to take off it bogs way down and sometimes dies. We are running 32:1 gas and plug is very oily with alot of oil coming out tailpipe. I pulled the carb and our main jet is a 135.....Damn. We are at 690 elevation. We have been advised to change to a 118 to 120. That sounds like a drastic change to me but looking at plug and oil out the pipe it may not be.

    2010 KX85 clutch issues.

    Thanks for the replies. I drained the oil completely and put in the 750cc. Runs like a charm. Thanks

    2010 KX85 clutch issues.

    First off Im a real newbie to this. Im almost positive Ive caused this problem. LOL. My son has a KX85 that we bought used and he has rode the living hell out of it the past week. Everything worked fine. Yesterday, not noticing the site glass on the oil case, I started pouring oil in the case because I couldn't see any oil when I looked down the fill hole. Quart later I still don't see anything. Long story short would to much oil cause the clutch not to work? It will not engage all of a sudden. Start bike in neutral and pull in clutch and put in gear and it trys to take off and stall. No laughing please.....lol. Im guessing it has a lot of extra oil. Didn't have time to drain and start fresh watching the site glass before it was time to go home. Thx
