Ec250 not revving out
Hey guys, just got a 2001 ec250 to play around on.
The bike doesn't seem to want to rev at full throttle on idle. Quick pump of the throttle is nice and crisp but pin it and it seems like it loses revs. This is my first 2stroke so im not an expert. Ive bored and replated the cylinder and put a rebuild kit in it. The bike was sitting around for awhile before i purchased it apparently. Any tips or am i just not doing something correctly The bike has a messico front pipe also, standard muffler Thanks guys |

I would start by checking the floats are even (not bent) and then make sure the float level is correct. http://www.gasgasrider.org/forum/showthread.php?t=11886
While you are doing this take a look at the needle and seat to confirm they are in good shape. Once you set the float level make sure the carb body is level when the bike is sitting level. It is on a complex angle in two directions and it can be hard to see. It is easy to verify with a short carpenters level with the tank off and the carb top off. Float level is step one and may correct your problem but if not we will cover jetting next. |

Another consideration after reviewing your float height is the silencer. The packing can get soaked with excessive oil and become restrictive. If you haven't already, you might want to repack the silencer and make sure that the rest of the pipe is clear.

How's the compression after the rebuild? What did you use for base gasket(s)?

Ive repacked my muffler. Will pull off the carby and have a good look at it. Appreciate all the advice
Compression is good. For a gasket i initually used a thin paper gasket that came with the kit. But it had oil blow through it. So i pulled it off and put some gasket good in there |

Try a new plug. Again.
