OK here goes... Picked up an 04 200 EXC few months back, needed some work to say the least, wont go into detail of all the things i've fixed on the bike just the current and most present issue I cant seem to fix... it is smoking IE blue smoke/lots of splooge to the point that at the end of a few hour's ride, it's out the tail pipe, running down the back and dripping onto the swing arm/rear break caliper and blue smoking quite a bit. When I first got it, it smoked more and smelled like shit. So first things first went to the carb, I live on the Oregon coast (elevation/temp reference) it's old dirty/stained but inside looks good, came with jetting pilot-45, main-178 needle: no idea what brand guessing stock in the 3rd clip, adjusted the float height due to it leaking gas when bike was upright no tilt with the gas on, Bought JD jet kit and running pilot-45, Main-185 and Needle is blue 3rd clip (JD's recommend specs for my bike @ my attitude). I have also replaced my Inner crankcase seal twice (First time I thought I messed up the O-ring so redid to make sure). I've rebuilt the top end/new piston (same thing) cleaned the PV, NOTE HERE that the PV has some issues, it seems to work fine but the screw that goes on top of the cylinder, down into the PV/flap would not come out preventing me from removing the flap to clean it, however it move's/ function's correctly, and has minimum clearance on both sides. One of the PV cover bolts that also works at the exhaust spring holder, was over torqued at some point (impact driver prob), or a result in a hard impact, the hole the bolt goes into is flailed/jared open a bit, not bad, not in the way of any function/ PV Gearing/hinge, it is not needed for that area to be air tight as their is also a breather that goes out of the PV so will not result in an "air leak" or loss in Top end PSI.... anyway... it's still smoking.... quite a bit.. now the bike itself rides fine I feel, the carb does puke gas when tilted over slightly/ hard to start (kick start) after flooded (like all bikes tho) I don't have any stalling/low idle issues outside of user error on clutch control. Honestly outside of it smoking as much as it does I would think nothing is wrong with it.. I have also tried raising the needle Clip to 2nd clip and it changed nothing at all, not even feel of the bike/response and have a new Spark plug I have yet to put on the bike. I have also "compromised" the crankcase Gasket (new one in the mail) while I was putting the Crankcase back on but that should do nothing with the exhaust just a little gear oil leak not relevant but throwing it out there. So I am at a loss... I've been toying with the idea of getting a Lectron carb... However... would hate to drop $400~$500 and the issue still persist, if it's a jetting/carb/float issue that would fix it and improve MPH/fuel consumption Or something with the PV? but I don't see the PV causing that much smoke/sploogee... I've ridden the bike normally/hard and nothing's happened but I don't want to keep pushing it and possibly clip the bike. Any ideas? "Oh help me 2 stroke community you're my only hope"
Hey guys, I just finished building up my 2001 XR as a winter project. She was pretty neglected when I got her. Low hours but sadly the last owner didn't treat her nicely at all. I lovingly went through everything except the engine with all new parts, and finally got it all together last week. It fired right up on two kicks with half choke, ran great for about a minute with the choke off, then (still choke off) it started running rich as heck: popping, coughing under power not idling, some puffs of black smoke, cutting out, smelling like unburned fuel, wanting to die without throttle, etc. Took it down the street and it got worse, so I put the choke on back to halfway, and it ran much better (not perfect but got me home). Still running a bit rough, but nevertheless tremendous arm socket pulling pig power with half choke. Took out the plug when I got home, really black and sooty as expected. I'd already rebuilt the carb, but I went through it all again with carb cleaner and compressed air two more times i.e. once, installed it, same problem, went through it again and installed it, same problem. I've checked everything. Its got an FMF header and can, with a Jet kit from Moose: Pilot jet is a 68s (tried a 68, no change), main is a 170, needle provided is at third clip as recommended. Fuel screw is at 2.5 turns, although it doesn't matter where it's at, same condition. Float is set at 17mm, needle seat and valve were polished with the q-tip-in-the-drill trick. The only issue that might be in play is the carb piston is scored for some reason, I got it that way from the previous owner. Do you think this could be the problem? Few other things, Ricky Stator 200w, brand spanking new BD dual sport kit, Uni filter (clean). New plug. Spark is really good, no problems there. This is the second Pig I've had, my first one was a 2000 and totally problem free and I badly regret selling it. This Pig is giving me the run around. Any help would be immensely appreciated, thanks in advance!
ttr125 works fine when running but to get it started I have to lay it on its right side for about 5 seconds. It will not start otherwise no matter how long I kick it and its been like that ever since I got it last fall. I got the carb professionaly cleaned and the oil changed but it still dosent start unless I sit there untill the daylight is gone or I lay it on its right side and it starts up like a charm.
