Crank seal sizes? EC300
Does anyone know the exact sizes of the left and right crank seals for the EC300?
I have a good seals and bearings shop nearby who can supply them. I'm currently having a problem running at WOT (wide open throttle). The bike runs great at CLOSED to 3/4 throttle, but won't run clean at WOT. After a couple of WOT plug chops the plug looks grey/lean. I'm a bit concerned as I've tried a 175 and a 180 main jet, just ordered a 185 main jet to try. I'm starting the suspect lean mixture at WOT might be caused by something other than jetting. By the way, I'm running in South of France, altitude 500m, temperature 20 to 30?C. Thanks, Dave. |

Are you certain you have good flow out of your petcock? Tank venting correctly? Carb vents dirty?
Since you tried a larger main jet, it sounds like it might be fuel starvation.

Hi Neil
Thanks for your reply. Yes I understand what you're staying about fuel starvation. Just this afternoon I checked the fuel flow out of the tap, also removed the tap and cleaned the filter, all looked good. I've removed, stripped and cleaned the carb, all seems ok. Regards, Dave. |
