2011 250ec/300 cylinder swap
Hey guy, i have a 2011 ec 250, i would like a little ore bottom end out of it,i was thinking of putting a 300 jug on it.
Here are my questions 1 will the 250 head work with the 300 cyl. 2 is there a better(cheaper) way of getting bottom end torque out of this bike , i just pit a piston and rings in it last year. i guess what iam looking for is a little more bottom end , my dad rides this bike now and he rides a little slower but still wants some bottom end grunt !!! thanks in advance guys |

Welcome to the forums.
1)The 250 head won't work on the 300. 2) There are several options. a) Install a flywheel weight. b) Install a high volume power valve cover-on left side of cylinder. Non e-start only. c) Adjust the power valve actuator to open the valves later. You will have to pull the clutch side cover off to do this. |

You're welcome.
For massive low end power, you'll have to get a 1998 Gas Gas. The motor has a counter balancer and a heavy magnetic type lighting coil. |

You could get the head set up properly, they are notoriously poor from factory.
Jet it a bit fat. Bigger rear sprocket, 52T. An FMF gnarly pipe. |
