Guess you need to rebuilt the carburetor
1992 thru 1999 then the 250 beartracker in 2000 basicaly same as timberwolf,
Check the reed valves 1 is probley broken if it is baackfiring thru the carburetor.
Here is a link below of a company specializing in blow thru carbs. Their 750cfm carb is good for 1000+hp.
I have a 1969 el camino 396 ss new holly 4bbl, timing set correctly, and sometimes gives a pop thru carb. please tell me the items to check over.
If it backfires thru the intake/carb the spark arrester prevents this. It is the metal looking air filter on carburetor...
The float on your carb is stuck down and letting gas flow into the oil thru the cylinder pass the rings and out thru the muffler.
dude it may vary from $4695 to $7899...just go thru proper study of market
if you have spark and not starting still check fuel lines and tank for debris or blockege in the fuell line, or the air filter may be too dirty fro air to sift thru try blowing they air cleaner out then replace and try startiing take the bell housing of the carb and scrub and spry with brake clean and replace . if no spark then try replaceing plug if that does not work trace back to where wire is.
Lightly turn the idle/fuel adjustment screws in the front of the carb (they run thru little springs) all the way clockwise til they stop, then out 1 and 1/2 turns. If it won't start and run there, its got other problems.
Hello: The point gap on a DT125 is basically the same as all bikes//////.012" thru .016"///////.014 inches is a good place to set them at.....Good Luck****
The only way gas would be able to get into the crankcase is when the engine is off, gas is leaking down thru the carb's and passing thru the rings into the oil. Does the engine run well ? Is there always gas in the oil, or did you have trouble starting the engine and flooded it. If it was flooded once, that would do it. Change oil and filter.
get a can of Carb Clean and spray outside of carb first, then remove all jets,and the bowl and remove the float and needle and seat,and spray thru all ports.blow out with low pressure air hose and put back together,make sure the needle is free and goes up anmd down with the float before asembly.
