Definetly have some carb issues. And they will need to come off,be cleaned,floats set,and synched. If youve never done this before,id suggest that this bike NOT be your first attempt. They are VERY finnicky!!
Hello, carbon is a hard deposit so there is really no safe chemical that will clean it. A lot of riders will use a torch, heat the pipe red hot and then chip it out. ---Of course if you have some nice pipes, nickle or chrome, it will discolor them. An ultrasonic parts cleaner will work, but not everbody has one of those...Here's a trick the old timers use to do back on the early model enduros.
Remove the pipe from the bike, remove the silencer/spark-arrestor. Now use a
rubber plug or cork in the silencer end of the pipe & cap it off.
Now pour about a
half of a can or bottle of drain cleaner into the head pipe, next fill the pipe
with HOT water and step back. The pipe will get very hot and you will hear and
see bubbling. Let it set for about a 1/2 hour then pour it out and remove the
cork and rinse the pipe in cold water.
If your pipe is really carboned
up you may need to do the above procedure a couple of times.
very cautious since drain cleaners can be dangerous, obey all precautions listed
on the bottle... wear gloves & goggles....Not many people know about this trick, it works well though. I hope this helps, & good luck with your bike.
Could be that you have blown the piston rings, firstly i would remove the rear silencer, as 2 strokes bellow out exsess smoke and loose power when the silencer becomes blocked due to carbon, start and run the bike and check without the silencer, furthermore to eliminate the exhaust itself is blocked, undo it from the cylinde
Grinding the valves will not affect the oil consumption or carbon build-up in the exhaust. Carbon can be from a rich mixture of fuel, but then the carbon will be a light powder that will rub off easily. If the carbon is hard and baked it will be a combination of fuel and oil, and the only ways you can get excessive oil int he exhaust is if the valve stem seals are leaking or if the rings are worn. Worn rings will make the machine smoke all the time but valve stem seals will make it smoke on first start-up of the day and also when you have rev-ed the machine and suddenly closed the throttle.
Please check your exhaust pipe or the silencer. It must have been chocked with carbon and you have to remove the carbon deposit to run your motorcycle. Also clean your fuel tank as it could have dust deposits at the bottom chocking the fuel flow once it is in running condition. Please change the spark plug as recommended after covering a distance specified.
If you are talking about the carbon, oil buildup, the easiest way is to put it on the grill or throw it in a fire! You will have to paint it afterwards, tho. I have seen people put it in diesel fuel or kerosene, and light it on fire, but always be super careful with flammable liquids! If it has a baffle or silencer, take it out also
but I was curious if I need some sort of rubber seal or a sealing compound for it. Thanks a lot!No you dont absolutly need it but it would be smart to have because I had the same thing happen on my yz125 and the carbon went everywhere and staind my swingarm. I just used a piece of old radiator tube because it was cheap and I didn't have to order it.,
