2011 250 with a drinking problem...
Hello
Just rode my 1st enduro yesterday. DNF mainly due to lack of fitness lol Severe arm pump stopped me halfway up a steep 500m long climb and took 45mins to get to the top of it again! and stopping to help someone whose chain sucked up between front sprocket and swing arm. Anyway it was a 35mile lap, I hit reserve around 32miles. Route was mixture of service roads, rocky trails and slow technical forest section with a few road sections in between. Bike pulls well and idles perfect. Starts easily from cold with no choke, usually need throttle pulled to get some air in when hot starting (normal for 2t?). Quite spoogy out the exhaust. Not a fast rider so mainly a gear higher and working the clutch rather than singing on the pipe apart from the more open bits. Could pilot be a bit too rich?? Or am I better going whole hog and see what the squish is like and fix that? cheers |

What are your current jetting specs? What level is the float set at.
My 2010 EC300 with stock jetting ran out of fuel by 70kms. After some head work and better specs I could ride the bike harder and get 100km before reserve. |

Ive only had it open once to check and set the floats (via info on here, AS2 carb) and everything checked out stock.
DISREGARD THIS POST SETTINGS WERE INCORRECT. SEE BELOW 180main 42 pilot airscrew set around 1.5 float 8mm rings a bell, doesn't leak on side stand N1EF needle middle/3rd #7 Slide Set for sea level, max altitude id likely encounter in this country would be around 600m Last edited by Thompo; 05-28-2018 at 03:39 PM. |

Ive been searching here and see the NEDW needle is recommended for the 250/300?
Would this give a more noticeable improvement in fuel economy than sorting the head (assuming the squish is "loose") |

Just pulled the carb.
My memory was not good!. 178 main 40 pilot N1EF 2nd from top #7 slide Air screw 2 turns Plug is currently black but I was just off idle for 300m with a half full 20l Jerry can on my lap before it was shut off. Idles perfect and i think it pulls well from low to high. bit smokey at 50:1 at idle maybe loads up if idling for any length of time but couple blips and it's cleared. Edit Checked float before and after Was in around 6.5mm to the highest point Set it to 8mm reducing amount of fuel in bowl. Does that look correct? Last edited by Thompo; 05-28-2018 at 04:15 PM. |
