    So installed a 86xt600 carb on my 85tt600...... Thx for all the
    Info everyone. The bike starts right up now, idles great, performs awesome. After installing the carb I realized I needed a new throttle (twist/pull) type so I got that. Like I said the carb worked wonders with no instalation or performance hiccups. I even located the stock airbox for it. Ebay, Craigslist, and my local part store I've pretty much found everything I need and continue to need. My new prob is I've got 2 oil leaks one will be fixed today which is a relatively easy fix. The other is the threads on one of my oil filter screws (case side) are stripped and gone completely. So I've filled the hole with jbweld and its been curing all week I will drill and tap it tomorrow. (Helicoil did not work) Hopefully it will be as good as it is stock. (Fingers crossed) if not I will have to figure something else out. Like I said the bike runs great and I can't wait to really get out for a day on the trails. I just need to get everything dialed in. I will keep ya posted. Btw Thx for the skid plate info I will invest in one of those after I get all my mech probs out of the way. Thump On Thumpers!!!!

    You could go for an alloy street sign bashplate but you need the frame rails to support it.

    The XT skid plate, bolts up with 4 bolts on the bottom of the skid plate. And in the front it bolts with one bolt. So, to put the the XT plate on the TT you will need the front motor mount off a XT bike. Good Luck! Thump-On!!:lol3

    85 tt600...... It was dead when I found it. Bought rebuilt stock carb, fired right up. Located stock air cleaner tubes installed uni boots at ends of air cleaner tube. Installed crankcase breather filter at end of breather tube where its suppose to go into air box. Ran fine, found about 17 oil leaks, located new stator cover, replaced gaskets on either side of crankcase, replaced oil tank, drilled out stripped crankcase threads for crsnkcase cover inserted thread inserts. All but one oil leak is now fixed. Now bike doesn't want to fire up by kicking. It use to. It will pull start at about 20 behind a truck. After started it seems to run.... I've got a little white smoke out of my exhaust, but I'm not to concerned about that. Main concern though my crankcase breather tube seems to be spitting a lot of oil and A LOT of white smoke that smells really rich. After I run it hard for about 5 minutes the breather tube @ filter starts hissing really loud spitting a shitload of oil then the bike dies out about 20 seconds after hissing begins........ Is my carb out of adjustment, do I have plugged oil jackets, is just a matter of a stock air box???? Im just lost now.... Please any advice is appreciated.
    Thx

    White/gray-ish smoke is usually oilburning.

    I pulled stator cover so I can replace, because its cracked. Upon doing so I leaned my bike over to see if I had oil in the crankcase. Low and behold a bunch of gas decided to pour out of my crankcase along with the oil. I think that's the answer to my white smoke issue. Also I found a small washer magnatized to my magneto. But would either of those still make my bike die out after it warms up??? Or make it hard to start??? Unfortunately I have to wait for a new stator cover in the mail before I can try to start it again. BTW what's the best way to flush my oil sytem??
    Thx
    Dan

    Ps the gas was my fault I had the bike on its side for a period of time (so as to not mis diagnose a problem).

    just drain the oil tank, filter , check to see if your air box has the same problem ,refill and run it to past full warm, leave the oil cap off to evaporate the last bit of fuel after you park it. smell your oil for fuel before the next run and decide if you are successful or just do it again.

    1985 tt600 I tried draining all oil and replaced guess I should check again and see if gas is in oil now. Bike still wouldn't start, I pulled it at about twenty and bumped it, after a lot of pulling it started, but immediately a lot of white smoke and a horrible hissing sound out of crankcase breather tube then it died. One thing I noticed is when I use to kick it over, every 3rd kick was really hard and i have to slowly push through that one and the next kick would usually start it. But now every kick is the same I don't get that same toughness every 3rd kick. Could I have a timing issue, if so how do I adjust? I think my stator is working ive got spark and my light lights up everytime I kick through. I've gone through my carby a couple times it seems to be okay. So it leaves me to believe, timing, piston, or rings?????? I don't get it. 1 month ago it ran fine it started right up then a bunch of white smoke came out of breather tube with a hissing sound and it died out. I laid it down for 2 weeks at about a 45 degree angle so it wouldnt leak oil as I was waiting for my stator cover to be welded. I put cover back on and now it wont start aside from bumping it. But when it does the symptoms are stated above. Originally I thought it was cuz I laid it down and gas got in my crankcase, but now I'm beginning to think differant..... Again, timing(please), piston, rings, or carby(please). Of course any input would be great. Thx,
    Dan

    put a bit of oil into the cylinder and kick it a few times with the plug out,should feel a better resistance if the rings were not previously sealed, put a fresh-good plug in a see if that will work.you may want to have the gas off the first time or two.have you checked the static compression? 8.5:1 is about 120-125 psi

    Am I mistaken or did you just tell me to pour oil down my spark plug hole???? That doesn't seem smart to me sounds like a lot of cleaning afterwards???? And how much is a "bit". Tried a new plug last week... No dice... :( need to get a compression tester....

    Just a drop of oil.:eek1 Not a quart of oil :lol3 And the new plug will burn the oil up. Do you have "new" gas in your tank?:evil

    Gotcha on the oil, and yeah my gas is good in the tank. What does the oil do? Ps how do I adjust my timing, and does this bike have points???:clap

    The oil will help the rings seal and bring the compression up for a short time if the ring seal is going bad. Timing is non-adjustable. It is electronically controlled in the CDI. No points.
    These bikes do have a bit of a reputation for the CDI units going bad.

    If the cdi unit is going bad, is it possible that there is still a spark but its sparking at the wrong time??

    I don't know. I have had what I believe, the timing advance quit working. I say I believe because I never actually checked it but by the way the bike was running--no power, not wanting to rev, exhaust sounding "flat"-- I came to that conclusion. Tried a different CDI unit and the bike woke right up.

    Another thing I have had happen is the plating flaking and peeling off of the cylinder bore. When that happens you loose power, burn oil, the compression gets lower or completely goes away, depending on how bad it is coming off and the bike gets hard, if not impossible to start.

    I bring this up because in one of your previous posts you say when kicking the bike over you noticed it doesn't get difficult to kick every 3rd time anymore like it used to. This sounds to me like you have lost compression.
    I would run a compression check if I were you. Disconnect the auto-decompressor cable that runs from the kickstarter area to the rocker cover before you take the reading.

    I didn't notice this until last night but the right side of my carb (the vacuum) side the plunged needle assembly was stuck halfway open, which very well could cause a hissing noise at idle and then shut down because there is to much air. Also my compression seemed to tighten up a little after I closed that needle with a pair of needle nose. It still won't kick over though. Today I will bump start it and manually close that valve at idle if it doesn't do it on its own and see if it still hisses. I will run comp test today I have to go buy a tester. I will let you guys know what happens. YDIS Grrrr this thing was recently rebuilt too...


    Okay the saga continues, couldn't even bump start it this time....wtf

    Have you done a compression test yet?
