I got a question. I own a 2016 KX 85. It ran AMAZING after it first bought it used and was in beautiful condition and I picked it up for only 2500. I was riding when all of a sudden it started bogging down right before the power band.i don’t think it’s jetting because the bogging just turned on like a switch and it was running perfect before it. The bike was like that for a month. Apparently the previous owner never oiled the filter so it was dry as a rock and was falling apart and got sucked into to the intake so I’m guessing my power valve is gummed up or stuck close or open. I was riding one day with the bog issue and about 35 minutes of riding I shut it off to take a break. Came back 20 minutes later and it would not start.I changed the spark plug, cleaned out the carb,checked the reeds,and tried hill starting it but nothing. When ever I try to hill start it I can hear it trying to crank and It starts for like half a second but then dies.I don’t remember if I left the fuel petcock on but what I’m guessing is that I flooded the engine and tried starting which messed up my electronics.The reason why I think I flooded the Engine is because when I took off the reeds the intake manifold and reed were soaked in gas.I heard that starting the engine while flooded can mess with a woodruff key or your CDI or something. There is spark coming from the plug though.And yes I mix the gas with oil at 32:1 cause I’m in the pipe all the time.This is my first time owning a 2 stroke.Any answers or tips.
I'm new to your forum and I tried searching for help on this topic before posting, but I wasn't' successful. Please forgive me if I missed the Topic that could have answered my questions. I am looking to purchase a 2001 XR650R from a friend, but it hasn't run in almost 2 years. It was stored with gas in it that went bad. After cleaning and disassembling the carb multiple times I'm stuck and I'm about to dump about $75 worth of new parts into the Carburetor just to see if it helps, but I'm not confident. Could you please help me figure this out? To date I've tried: 1.5 bottles of Mechanic in a Bottle (MiaB) mixed 50/50 with ethanol free gas. (No start) Running the old gas out until the MiaB has sat overnight (No start) Removing the carb, complete disassembly and (soaking in Gunk carb cleaner bath for the recommended 20 minutes) -- 2 batches, small parts and body separately. Then we cleaned all the parts individually until spotless. Reassembled carb (with pictures to insure it was reassembled correctly) -- at this point the carb was spotless (started for up to 2 mins 1 time, but could not keep it running). Checked that it was making compression, though didn't test if it was adequate compression, decompression lever working well. Checked that the spark plug was sparking, but we did not test if it was strong spark. (No start) Disassembled again re-cleaned all the parts and hoses with spray in carb cleaner and ensured that EVERY passage was blown out reassembled (No start) Tried every combination of air screw, throttle settings, choke, kill switch and throttle position we could. Checked for spark, and adjusted valves, .006 and .008. During these attempts used starter fluid (No start) Cleaned off the spark plug, as it was wet after all these attempts, and it was sooty and wet. Cleaned it to shiny but did not check the gap. (No start) Towed behind a truck for several attempts to start and no joy, wouldn't even run well while actively being towed (No start, wouldn't run) We adjusted the float several times to ~16mm to keep it from pissing fuel during our vigorous starting attempts. (No start) I think there might have been a high altitude kit in the bikes past because the jets are pilot:065 and main:118. I believe the stock sizes are 68s and 125. My current altitude is about 4000 ft, and I plan to do most of my riding around 4500-7000 ft. With an occasional ride around 1000ft. Could this be part of the issue? To date I've purchased a complete rebuild kit to include the stock jets, metering rod, o-rings, ect, and new floats, new plug but have not installed because I don't want to waste money if it won't help. I'd really appreciate some help as we have spent soo many hours on this it has become incredibly frustrating having no success, and the more cleaning we do seems to make it worse. It would be very helpful to know what the best starting settings are for this bike/carb [choke, air screw, throttle, clutch, decompression lever ] just incase that is something we aren't doing right, though between my friends and I we've probably tried them all. --- Here is a link to the album on FB. These are the disassembly pictures before cleaning, only the last few are of clean parts. I have lots more pictures, but I couldn't figure out what was useful. https://www.facebook.com/patrick.moon.9/media_set?set=a.10221999157194013&type=3
My 2008 raptor 250 has never started right. It nevers hit right away, and if its just a little cold it will not come close to starting. I have bought a new starter battery and selonoid and it still doesnt start right and if i keep try and keep starting it will break the selonoid, and i will have to get a new one, which has happened 3 times. It will start but, never has right so what do i need to do so it doesnt keep blowing my selonoid and so it starts right up. btw the motor and everything is perfect it just doesnt start right.
